is a chemical library that explores the chemical space broadly by enumerating more than 160 billion organic small molecules with up to 17 atoms.

For example, GDB‐17 generated by Reymond et al. Thus, many researchers are developing new de novo chemical libraries and libraries “make-on-demand” by different in silico approaches. One approach to increase the likelihood of finding new hit compounds is presented by the computational generation of virtual chemical libraries to be used in various virtual screening methods. Hit identification is the starting point and one of the most crucial stages of small-molecule drug discovery. This manuscript also seeks to contribute to the critical task of teaching and learning chemoinformatics. As part of the tutorial, we discuss three examples of design: a Diversity-Oriented-Synthesis library based on lactams, a bis-heterocyclic combinatorial library, and a set of target-oriented molecules: isoindolinone based compounds as potential acetylcholinesterase inhibitors. The aim is to explore various methodologies proposed by synthetic organic chemists and explore affordable chemical space using open-access chemoinformatics tools. This tutorial shows a step-by-step procedure for anyone interested in designing and building chemical libraries with or without chemoinformatics experience. To exemplify the enumeration of chemical libraries, we emphasize the use of pre-validated or reported reactions and accessible chemical reagents.

This paper aims to examine the fundamental concepts of library design and describe how to enumerate virtual libraries using open source tools. Virtual compound libraries are increasingly being used in computer-assisted drug discovery applications and have led to numerous successful cases.
