In this study, we explored the pharmaceutically underexploited mycobacterial gyrase ATPase (GyrB) domain as a template for a structure-based virtual screening of our in-house (BITS Pilani) compound collection to discover new inhibitors targeting Mycobacterium tuberculosis (M.tb.) The hit identified was further customized by using a combination of molecular docking and medicinal chemistry strategies to obtain an optimized analogue displaying considerable in vitro enzyme efficacy and bactericidal properties against the M.tb. H 37Rv strain. The binding affinity of the ligand toward the GyrB domain was reascertained by differential scanning fluorimetry experiments. Further evaluation of the hERG toxicity (a major limitation among the previously reported N-linked aminopiperidine analogues) indicated these molecules to be completely devoid of cardiotoxicity, a significant achievement within this class.
Basic techniques of working on a solid phase: From ABC of the peptide synthesis to libraries of non-natural amino acids
Babaev,Ermolat'ev
experimental part, p. 2572 - 2589 (2011/04/15)
Libraries of hardly available amino acids bearing a heteroaromatic ring (2-pyrimidyl, substituted 2-pyridyl or 2-thiazolyl) at the amino group were prepared using solid-phase synthesis on various resins. The synthesized compounds are structurally similar to some known antidiabetic drugs. The paper combines features of a review (elementary introduction to the solid-phase synthesis methodology and technique for beginners and selected methods from peptide chemistry) and step-by-step experimental protocols (tested by the authors) useful as a methodic tool. The presented protocols (immobilization and modification of amino acids, placing and removal of common protective groups) require no sophisticated equipment and may be useful as pictorial introductory tasks for students education.
