The development of medicinal chemistry is advancing very rapidly. Big pharmaceutical companies, research institutes and universities are working on ground-breaking solutions to help patients combat all kinds of diseases. During that development process, tons of data are generated – not only from the lab environment but also from clinical trials. Given that the discovery of more potent, safer and cheaper drugs is the ultimate goal of all research bodies, we should all focus on making the data we gather FAIR: Findable, Accessible, Interoperable, and Reusable to push the boundaries of drug development even further.

With the currently available methods such as artificial intelligence, machine learning, many toolkits, software and access to various databases, managing big data is now inherently linked to medicinal chemistry and helps to make this area as efficient as it can be.

In this tutorial, we will therefore explore some concepts related to medicinal chemistry, explore the available chemical and pharmacological databases, and perform some basic data analyses using the Galaxy interface.

Principles of medicinal chemistry research

Drug-likeness

There are many factors that medicinal chemists take into account while designing new drugs. It is essential to estimate the properties of the molecule before synthesising it in the lab, so the structures of drug candidates are usually compared to the existing drugs by so-called drug-likeness. This includes intrinsic properties of a compound that will lead to favourable ADMET (Absorption, Distribution, Metabolism, Excretion, Toxicity) characteristics. Below are some properties usually assessed:

• Lipophilicity
• Size
• Polarity
• Insolubility
• Unsaturation
• Flexibility

Additionally, there have been some rules developed to help estimate drug-likeness, amongst which:

• Lipinski rule (Lipinski et al. 2001)
• Ghose rule (Ghose et al. 1999)
• Veber rule (Veber et al. 2002)
• Egan rule (Egan et al. 2000)
• Muegge rule (Muegge et al. 2001)
• Abbott bioavailability score (Martin 2005)

As you see, there are a number of characteristics to consider before even synthesising the molecule in a lab. One of the online tools that help to summarise all the most important information about intrinsic properties and drug-likeness of compounds is called SwissADME and is a free web tool to evaluate pharmacokinetics, drug-likeness and medicinal chemistry friendliness of small molecules (Daina et al. 2017).

Below we briefly discuss two probably the most well-known rules: Lipinski’s and Veber’s rules.

The Lipinski rule of 5

This rule of thumb developed back in 1997 by Christopher Lipinski and colleagues tries to predict the likelihood that a given small molecule can be orally active. The Lipinski rule of 5 favours molecules as potential oral drug candidates if:

• the molecular mass is less than 500
• the calculated logarithm of the octanol−water partition coefficient (clogP) is less than 5
• they have up to 5 H-bond donors
• they have up to 10 H-bond acceptors

However, nowadays there are more and more drugs being developed which don’t comply with those rules and regardless are still effective. There are voices from the scientific community, pointing out that “We are in danger of repeating our past mistakes if we assume these new modalities are not ‘drug-like’ and cannot be oral drugs because they are not [rule of 5] compliant” (Michael Shultz from Novartis, cited in Mullard 2018 where the authors re-assess the rule of 5). Then, in O′Hagan et al. 2014 we read “This famous “rule of 5” has been highly influential in this regard, but only about 50 % of orally administered new chemical entities actually obey it.”

Veber’s rule

In (Veber et al. 2002) we read that the commonly applied molecular weight cutoff at 500 does not itself significantly separate compounds with poor oral bioavailability from those with acceptable values. The authors explain that on average both the number of rotatable bonds and polar surface area or hydrogen bond count tend to increase with molecular weight which may in part explain the success of the molecular weight parameter in predicting oral bioavailability. Their observations suggest that compounds will have a high probability of good oral bioavailability if they meet the two criteria:

• 10 or fewer rotatable bonds - increased rotatable bond count has a negative effect on the permeation rate
• a polar surface area no greater than 140 Å ² (or 12 or fewer H-bond donors and acceptors) - reduced polar surface area correlates better with increased permeation rate than does lipophilicity

Big data for drug discovery

Have you ever wondered how new drugs are developed? It is actually quite a long and complex pathway and not only takes lots of time but also resources. The scheme below will help you understand the scale of that process.

As you can see, to get just one drug to the market, often thousands of structures are assessed to find the most effective and safe compound. That’s lots of information being generated in the whole process! The information can be stored in repositories and databases so that subsequent drug discovery process in a similar area is easier, faster and cheaper. Managing big data and using machine learning and computational chemistry methods is crucial in the lead optimisation step. By reviewing chemical databases and studying molecular docking simulations, we can save much time and resources to synthesise only those compounds that are the most promising based on in-silico methods. Even after synthesising the optimised ‘leads’, we still get lots of data from tests and analyses. By using appropriate cheminformatic tools and software, we can use the results to drive forward this iterative process of lead optimisation.

Ten Vs of big data for drug discovery

Hopefully, now you have an idea of what the process of drug discovery looks like. To understand why managing data in medicinal chemistry is so challenging, let’s have a closer look at the “Ten Vs” of big data Zhao et al. 2020:

• Volume: size of data.
• Velocity: speed of new data generation.
• Variety: various formats of data.
• Veracity: quality of data.
• Validity: authenticity of data.
• Vocabulary: terminology of data.
• Venue: platform of data generation.
• Visualization: view of data.
• Volatility: duration of data usefulness.
• Value: the potential of data usefulness to reduce the cost of drug discovery and development.

Medicinal chemists must keep in mind those features while both searching for data and publishing it. In this way we can focus on the main aspects of data management, try to improve the availability and normalisation of data, and be aware of limitations of repositories and inconsistencies in data quality.

FAIR MedChem

As you saw before, there are many properties that the compounds can be searched by, such as molecular weight, H-bond donors or acceptors, polarity, etc. Sometimes there is a need to assess other molecular properties but it might happen that not all the information is included in the database. This is one of the reasons why new repositories are being developed – they are more specific and gather particular properties of interest. How much easier the life of scientists could be if the relevant data was publicly available, well-ordered and contained the needed metadata? By submitting the data with the necessary information to the repository is a good way to make the data FAIR. This will make it:

• Findable, as the data will be given specific identifiers
• Accessible, as the data will be available online, open and free where possible
• Interoperable, as the repository will often enforce the use of formalised, consistent language
• Reusable, as the data will be released under a license with detailed provenance In the repositories

Chemical and pharmacological databases

Currently, there are lots of publicly available databases storing information about hit molecules, chemical structures and properties, drug targets, pharmaceuticals… In the recent paper Zhao et al. 2020 the authors collated relevant databases to advance computer-aided drug discovery and divided them into several main groups:

• Chemical collections
• Drug / drug-like compounds
• Drug targets, including genomics and proteomics data
• Biological data from assay screening, metabolism, and efficacy studies
• Drug liabilities and toxicities
• Clinical databases

Below you will find the databases listed under corresponding categories, all taken from Zhao et al. 2020 paper.

There are many more databases available, and many are still being developed. They are often quite specific and contain certain types of compounds (eg. PROTACs or are aimed at a particular disease. If the listed databases are not specific enough for your research, you can try luck by searching smaller, more specific databases.

Data management in chemistry using Galaxy

Chemical file formats

Depending on the type of analysis you are going to perform, you will work with different file formats. Below are the most important data types, commonly used in cheminformatics, that you will likely see in Galaxy:

• SDF (.sd, .sdf) - stands for Structure-Data Format, and SDF files wrap the molfile (MDL Molfile) format. Stores information about the chemical structure and associated data of compounds in plain text. Files in SDF format can encode single or multiple molecules that are then delimited by lines consisting of four dollar signs. SDF files are formatted ASCII files that store information about the positions of the individual atoms (either in 2D or 3D space) that make up the molecule. The data on connectivity and hybridization state are also encoded, although their use is less frequent and often inconsistent.
• MOL (.mol) - an MDL Molfile for holding information about the atoms, bonds, connectivity and coordinates of a molecule.
• MOL2 (.mol2) - a Tripos Mol2 file is a complete, portable representation of a SYBYL molecule. It is an ASCII file which contains all the information needed to reconstruct a SYBYL molecule
• CML (.cml) - Chemical Markup Language (ChemML or CML) is an approach to managing molecular information using tools such as XML and Java. It supports a wide range of chemical concepts including molecules, reactions, spectra and analytical data, computational chemistry, chemical crystallography and materials
• InChI (IUPAC International Chemical Identifier) - a textual identifier for chemical substances, designed to provide a standard way to encode molecular information. The identifiers describe chemical substances in terms of layers of information — the atoms and their bond connectivity, tautomeric information, isotope information, stereochemistry, and electronic charge information (Heller et al. 2015)
• SMILES (.smi) - the simplified molecular-input line-entry system (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. A linear text format which can describe the connectivity and chirality of a molecule (Weininger 1988)
• PDB - the Protein Data Bank (PDB) file format is a textual file format describing the three-dimensional structures of molecules held in the Protein Data Bank, now succeeded by the mmCIF format. It contains a description and annotation of protein and nucleic acid structures including atomic coordinates, secondary structure assignments, as well as atomic connectivity. In addition, experimental metadata is stored. (Berman 2007)
• GRO (.gro) - a plain text file storing spatial coordinates and velocities (if available) of atoms during a molecular dynamics simulation, utilised by GROMACS

To visualise the structures held by the files with the positions of the individual atoms, you can use (NGL Viewer)[https://nglviewer.org/ngl/].

If you plan to work with molecular dynamics simulations, there are also some MD trajectory file formats that you might want to get familiar with. In Galaxy, you can convert between xtc, trr, dcd and netcdf files using a tool called MDTraj file converter ( Galaxy version 1.9.6+galaxy0).

Galaxy tools

In Galaxy Chemical Toolbox there are dozens of tools that can be used for various analyses. Below we will only show a few, mostly related to data import, format conversion and some functions linked to what was discussed previously.

Let’s start with importing publicly available data. Protein Data Bank stores thousands of three-dimensional structural data of proteins nucleic acids and other biological molecules.

Hands-on: Import PDB file from Protein Data Bank

1. Open Protein Data Bank
2. Type your search term in the box “Enter search term(s), Entry ID(s), or sequence”: MAO B

Open image in new tab

1. Choose the structure of interest and copy its accession code: 2BK3

Open image in new tab

1. Switch to Galaxy
2. Get PDB file ( Galaxy version 0.1.0) with the following parameters:
   • “PDB accession code”: 2BK3

This is often the first step of docking studies that you can learn about in other tutorials, for example in Protein-ligand docking tutorial.

You can import any molecule to Galaxy using SMILES notation. Below we show an example with benzenesulfonyl chloride and ethylamine.

Hands-on: Import SMILES

1. Copy SMILES of your molecule(s) of interest. In this example, we use benzenesulfonyl chloride (SMILES: C1=CC=C(C=C1)S(=O)(=O)Cl) and ethylamine (SMILES: CCN).
2. Click on the galaxy-upload Upload data button in the tools panel on the left-hand side.
3. Click on the galaxy-wf-edit Paste/Fetch data button twice. Two boxes will appear.
4. In the first box, under “Name” section, enter Benzenesulfonyl chloride and under “Type”: smi
5. Below paste the SMILES of benzenesulfonyl chloride: C1=CC=C(C=C1)S(=O)(=O)Cl
6. In the second box, under “Name” section, enter Ethylamine and under “Type”: smi
7. Below paste the SMILES of ethylamine: CCN
8. Click the “Start” button, then close the dialogue box. Your files are being added to your history!

As you learned from the previous section, there are many different formats used in computational chemistry. Of course, Galaxy allows you to interconvert between them - just have a look below!

Hands-on: Convert the file format

1. Compound conversion ( Galaxy version 3.1.1+galaxy0) with the following parameters:
   • param-files “Molecular input file”: click on param-files Multiple datasets icon and choose both Benzenesulfonyl chloride and Ethylamine
   • “Output format” - you have many options to choose from! Not only the formats but also the associated parameters. Just scroll the list and pick the one that is relevant to your downstream analysis. Here we use MDL MOL format (sdf, mol)
2. Rename galaxy-pencil the corresponding files Benzenesulfonyl chloride SDF and Ethylamine SDF. Before renaming the files, make sure to check either the starting dataset numbers or the atoms in the file in order not to confuse the two files!

We intentionally chose to work on benzenesulfonyl chloride and ethylamine. Do you know why? Well, if you think about the synthesis of sulfonamides, that’s exactly what you need - a sulfonyl chloride and an amine. So… let’s do some computational synthesis!

Hands-on: Run the reaction

1. Reaction maker ( Galaxy version 1.1.4+galaxy0) with the following parameters:
   • param-file “Input file”: Benzenesulfonyl chloride SDF
   • “Reagent options”: Sulfonamide
   • param-file “Reagent file”: Ethylamine SDF

Tip: Reaction maker tool works also with SMILES!

Above we converted the .smi file into .sdf to show how tool Compound conversion tool works. However, it is worth pointing out that tool Reaction maker works also with SMILES files and the conversion happens automatically so that your .smi dataset is imported as .sdf input.

Details: Which reactions I can run using this tool?

tool Reaction maker works with more reaction types, such as:

• Amides synthesis
• Nucleophilic aromatic substitution (SNAr mechanism)
• Urea
• Suzuki coupling
• Sulfonamide
• Reductive amination
• N-alkylation
• Ether coupling
• Ester coupling
• Benzimidazole
• Triazole
• Benzoxazole
• Sarah Cu
• Sarah Quat Am

The output is the .txt log file and the SDF file with the product molecule. If you have a look at that file, you’ll see that there is just a list of atoms with their corresponding coordinates. To draw the resulting structure, we can use another tool.

Hands-on: Visualisation of compounds

1. Visualisation ( Galaxy version 3.1.1+galaxy0) with the following parameters:
   • param-file “Molecular input file”: SDF output for Reaction maker
   • “Property to display under the molecule” - there are many properties that you can choose from! Please note that sometimes if not enough information is provided, then the property might not be displayed. Let’s choose a basic but useful property: Molecular weight
   • “Format of the resulting picture”: SVG

Since we spoke about the drug-likeness in the previous section, let’s see how it works in practice, on the example of our “synthesised” molecule.

Hands-on: Estimate the drug-likeness

1. Drug-likeness ( Galaxy version 2021.03.4+galaxy0) with the following parameters:
   • param-file “Molecule data in SDF or SMILES format”: SDF output for Reaction maker
   • “Method” - two possible methods to weight the features are available - one based on max. weight (QEDw,max), and the other on mean weight (QEDw,mo). There is also an option to leave features unweighted (QEDw,u) and we’ll choose this one: unweighted (QEDw,u)
   • “Include the descriptor names as header”: param-toggle Yes

Details: What are the assessed properties?

The eight properties used are molecular weight (MW), octanol–water partition coefficient (ALOGP), number of hydrogen bond donors (HBDs), number of hydrogen bond acceptors (HBAs), molecular polar surface area (PSA), number of rotatable bonds (ROTBs), number of aromatic rings (AROMs) and number of structural alerts (ALERTS).

In medicinal chemistry, we often base the new structures on scaffolds of existing drugs. Therefore, it is quite useful to be able to find similar structures - below is an example of how to do it in Galaxy.

Hands-on: Search ChEMBL database for similar compounds

1. Search ChEMBL database ( Galaxy version 0.10.1+galaxy4) with the following parameters:
   • “SMILES input type”: File
   • param-file “Input file”: Benzenesulfonyl chloride
   • “Search type”: Substructure
2. Rename galaxy-pencil the output file Benzenesulfonyl chloride substructures

Tip: Search ChEMBL database tool works also with SDF!

Even though the input format of the above tool is SMILES, it can automatically interconvert between .sdf and .smi formats, so you don’t have to use tool Compound conversion tool beforehand.

Details: Parameters of Search ChEMBL database tool

tool Search ChEMBL database tool allows for searching the ChEMBL database for compounds which resemble a SMILES string. Two search options are possible:

• similarity (searches for compounds which are similar to the input within a specified Tanimoto cutoff)
• substructure (searches for compounds which contain the input substructure)

Results can be filtered for compounds which are

• approved drugs
• biotherapeutic
• natural products
• fulfil all of the Lipinski rule of five criteria

Let’s repeat this step, but with Lipinski’s Rule of Five which you learned about in the previous section of this tutorial!

Hands-on: Search ChEMBL database for similar compounds using the Lipinski rule of five

1. Click the galaxy-refresh Repeat button on the previous dataset.
2. You will be redirected to Search ChEMBL database ( Galaxy version 0.10.1+galaxy4). Leave all the parameters as before, except for one:
   • “Filter for Lipinski’s Rule of Five”: param-toggle Yes
3. Rename galaxy-pencil the output file Benzenesulfonyl chloride Lipinski substructures

Question

How many molecules have been filtered out?

Solution

If you click on the dataset, you will see a short summary of how many molecules have been found. When we didn’t apply any filters, the tool found 45 molecules. After applying Lipinski’s Rule of Five filter, 36 molecules satisfied the rules.

Galaxy workflow summary

Those are just a few tools, but they offer many parameters that you can tune depending on your analysis. Additionally, we provide you with an example history and the dedicated workflow of this small tutorial. You are more than welcome to explore other tools in the Galaxy Chemical Toolbox though!

Data-driven medicinal chemistry - yesterday, today and tomorrow

Why do we need big data in med-chem?

In the article by Lusher et al. 2014 the role of the medicinal chemist is to make decisions about which of the infinite possibilities of new compounds should be made next. As the amount and variety of data on which to base these decisions grows, so too must the data analysis skills of the medicinal chemist. The authors claim that modern medicinal chemists should be able to recognise sources of relevant information, prepare raw data, use statistical tools, extract meaningful information, interpret results, recognise potential problems and make visualisations to communicate their findings to improve the quality of compounds being produced in research. According to the authors, this situation will require improved education and increased access to data and information management tools. This is where Galaxy comes in, offering not only a platform for data analysis with a plethora of the most commonly used tools in the field but also educational materials allowing anyone to learn and excel in analysis.

The privilege of applying computational methods in medicinal chemistry pipelines allows to focus on the most promising compounds and to remove unsuitable ones before the stage of chemical synthesis. Not only is this approach more efficient but also more sustainable and can reduce the costs of the synthetic stage of drug discovery (Brown et al. 2018).

Another important role that big data plays in drug discovery is target identification (and validation) which might be currently one the biggest challenges in medicinal chemistry. By introducing genomic data in drug discovery, we can produce more specific and effective medicines. Understanding the underlying causes of the disease and the biological targets are crucial in designing new drugs and hence should be inherently linked with this process, where possible.

Data challenges

It is important to understand the limitations of the databases we use since if data is not well understood, the processing and analysis drawn may ultimately be flawed, following the ‘garbage in, garbage out’ principle. Here are some challenges mentioned in Brown et al. 2018 that you can explore more in-depth by referring to that article.

• Errors
• Reproducibility
• Standardisation
• Formatting of data
• Information held in silos
• Loss of contextual information
• Limited and biased data

Machine learning in med-chem

Given the huge number of molecules in the various databases, applying machine learning in cheminformatics and building predictive models of the physiochemical properties of molecules is more and more popular. It helps to predict absorption, distribution, metabolism, excretion, toxicity (ADMET), likelihood of interaction with the drug targets as well as off-target effects. It can be useful in elucidating complex protein-protein or drug-drug interaction networks, in understanding structure-activity relationships (SARs) and when combined with data from the ‘omics’ revolution. This approach also helps to identify bioisosteres and introduce the idea of scaffold hopping in molecular design (Brown et al. 2018).

Knowledge sharing

It is not only about gathering and managing the data but also building a culture of knowledge sharing. We work in big, international teams with well-established methods and well-equipped labs. There are so many opportunities for knowledge capture and exchange! The challenge emerges here though – how to efficiently connect and help each other? This is the question that many pharmaceutical companies try to answer, such as Merck & Co. who describe their approach to knowledge management and report on the multiple enduring and complementary teams and initiatives to capture and share knowledge (Beshore et al. 2022).

Key points

• The power of big data might be useful to shape innovations of the future in the pharmaceutical field.

• There are many publicly available databases used for drug discovery and development and they might look at the same medicines from different angles and classify them based on various factors.

• Galaxy provides tools and a platform for medicinal chemistry analyses.
