The unique chemical diversity available in these libraries represents the space occupied by ligands known to interact with a specific target.This type of information is used in ligand-based drug design (LBDD) methods [7].Molecular docking, structure-based virtual screening (SBVS) and molecular dynamics (MD) are among the most frequently used SBDD strategies due to their wide range of applications in the analysis of molecular recognition events such as binding energetics, molecular interactions and induced conformational changes [6].A distinct approach in drug design comprises the use of bioactive small-molecule libraries.When identifying a drug target, we first need to answer some general questions: Does the target protein belong to a biochemical pathway, which can be bypassed by the cell, if inhibited?

These techniques have allowed the resolution of more than 100,000 three-dimensional protein structures, providing vital structural information about key macromolecular drug targets [3].

Virtual screening has become a standard tool in drug discovery to identify novel lead compounds that target a biomolecule of interest.

I present several concepts in ligand-based and structure-based virtual screening and discuss some of the current shortcomings and new developments.

SBDD refers to the systematic use of structural data (e.g., macromolecular targets, also called receptors), which are usually obtained experimentally or through computational homology modeling [13].

The purpose is to conceive ligands with specific electrostatic and stereochemical attributes to achieve high receptor binding affinity.Looking at the structural side, the authors used the Most modern drug discovery projects start with protein target identification and verification to obtain a “verified drug target”.
