  • Report on an NIH Workshop on Ultralarge Chemistry Databases Wendy A
    1 Report on an NIH Workshop on Ultralarge Chemistry Databases Wendy A. Warr Wendy Warr & Associates, 6 Berwick Court, Holmes Chapel, Cheshire, CW4 7HZ, United Kingdom. Email: [email protected] Introduction The virtual workshop took place on December 1-3, 2020. It was aimed at researchers, groups, and companies that generate, manage, sell, search, and screen databases of more than one billion small molecules (Figure 1). There were about 550 “attendees” from 37 different countries. Recent advances in computational chemistry have enabled researchers to navigate virtual chemical spaces containing billions of chemical structures, carrying out similarity searches, studying structure-activity relationships (SAR), experimenting with scaffold-hopping, and using other drug discovery methodologies.1 For clarity, one could differentiate “spaces” from “libraries”, and “libraries” from “databases”. Spaces are combinatorially constructed collections of compounds; they are usually very big indeed and it is not possible to enumerate all the precise chemical structures that are covered. Libraries are enumerated collections of full structures: usually fewer than 1010 molecules. Databases are a way to storing libraries, for example, in a relational database management system. Figure 1. Ultralarge chemical databases. (Source: Marcus Gastreich based on the publication by Hoffmann and Gastreich.) This report summarizes talks from about 30 practitioners in the field of ultralarge collections of molecules. The aim is to represent as accurately as possible the information that was delivered by the speakers; the report does not seek to be evaluative. 2 Welcoming remarks; defining a drug discovery gateway Susan Gregurick, Office of Data Science and Strategy, NIH, USA Data should be “findable, accessible, interoperable and reusable” (FAIR)2 and with this in mind, NIH has been creating, curating, integrating, and querying ultralarge chemistry databases.

It has been estimated that GPCRs represent more than 30% of current drug targets and have attracted many pharmaceutical industries as well as academic groups for potential drug discovery. Cannabinoid (CB) receptors, members of GPCR superfamily, are also involved in the activation of multiple intracellular signal transductions and their endogenous ligands or cannabinoids have attracted pharmacological research because of their potential therapeutic effects. In particular, the cannabinoid subtype-2 (CB2) receptor is known to be involved in immune system signal transductions and its ligands have the potential to be developed as drugs to treat many immune system disorders without potential psychotic side- effects.

Here we describe an AI strategy, retro drug design, or RDD, to generate novel small molecule drugs from scratch to meet predefined requirements, including but not limited to biological activity against a drug target, and optimal range of physicochemical and ADMET properties. Traditional predictive models were first trained over experimental data for the target properties, using an atom typing based molecular descriptor system, ATP. Monte Carlo sampling algorithm was then utilized to find the solutions in the ATP space defined by the target properties, and the deep learning model of Seq2Seq was employed to decode molecular structures from the solutions. To test feasibility of the algorithm, we challenged RDD to generate novel drugs that can activate µ opioid receptor (MOR) and penetrate blood brain barrier (BBB). Starting from vectors of random numbers, RDD generated 180,000 chemical structures, of which 78% were chemically valid. About 42,000 (31%) of the valid structures fell into the property space defined by MOR activity and BBB permeability.

    A Java Tool for the Management of Chemical Databases and Similarity Analysis Based on Molecular Graphs Isomorphism Irene Luque Ruiz and Miguel Ángel Gómez-Nieto University of Córdoba. Department of Computing and Numerical Analysis. Campus de Rabanales. Albert Einstein Building E-14071 Córdoba (Spain) {iluque,mangel}@uco.es Abstract. This paper describes a computational chemistry solution for the management of large chemical databases of molecules and the performing of isomorphism calculation for the analysis of database similarity and diversity. The system has been fully developed using Java language and it uses other free and standard Java library. The system allows to the user the building of databases of molecules, store information about the molecules, the matching among molecules using different isomorphism paradigms and the similarity/diversity analysis of databases through a wide number of similarity indices. Keywords: Computational chemistry, isomorphism, matching, similarity and diversity analysis, chemical database management, Java. 1 Introduction The investigations in Computational Chemistry [1] use computers to assist in solving chemical problems, they incorporate the results of theoretical chemistry into efficient computer programs, aimed to calculate the structures and properties of molecules. While its results normally complement the information obtained by chemical experiments, computational chemistry find predict hitherto unobserved chemical phenomena. Several major areas may be distinguished within computational chemistry [1-3]: − The prediction of the molecular structure of substances. − Storing and searching for data on chemical entities. − Identifying correlations between chemical structures and properties (QSPR and QSAR). − Computational approaches to help in the efficient synthesis of compounds. − Computational approaches to design molecules that interact in specific ways with other molecules (e.g.

  • Mining Collections of Compounds with Screening Assistant 2
    Le Guilloux et al. Journal of Cheminformatics 2012, 4:20 http://www.jcheminf.com/content/4/1/20 SOFTWARE Open Access Mining collections of compounds with Screening Assistant 2 Vincent Le Guilloux1*, Alban Arrault2, Lionel Colliandre1,Stephane´ Bourg3, Philippe Vayer2 and Luc Morin-Allory1* Abstract Background: High-throughput screening assays have become the starting point of many drug discovery programs for large pharmaceutical companies as well as academic organisations. Despite the increasing throughput of screening technologies, the almost infinite chemical space remains out of reach, calling for tools dedicated to the analysis and selection of the compound collections intended to be screened. Results: We present Screening Assistant 2 (SA2), an open-source JAVA software dedicated to the storage and analysis of small to very large chemical libraries. SA2 stores unique molecules in a MySQL database, and encapsulates several chemoinformatics methods, among which: providers management, interactive visualisation, scaffold analysis, diverse subset creation, descriptors calculation, sub-structure / SMART search, similarity search and filtering. We illustrate the use of SA2 by analysing the composition of a database of 15 million compounds collected from 73 providers, in terms of scaffolds, frameworks, and undesired properties as defined by recently proposed HTS SMARTS filters. We also show how the software can be used to create diverse libraries based on existing ones. Conclusions: Screening Assistant 2 is a user-friendly, open-source software that can be used to manage collections of compounds and perform simple to advanced chemoinformatics analyses. Its modular design and growing documentation facilitate the addition of new functionalities, calling for contributions from the community.
