[PMID: 36459759 DOI: 10.1016/j.ejmech.2022.114946] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 11/17/2022] [Accepted: 11/18/2022] [Indexed: 11/23/2022]
Abstract
Small molecules with antitubercular activity containing the pyrimidine motif in their structure have gained more attention after three drugs, namely GSK 2556286 (GSK-286), TBA-7371 and SPR720, have entered clinical trials. This review provides an overview of recent advances in the hit-to-lead drug discovery studies of antitubercular pyrimidine-containing compounds with the aim to highlight their structural diversity. In the first part, the review discusses the pyrimidine compounds according to their targets, pinpointing the structure-activity relationships of each pyrimidine family. The second part of this review is concentrated on antitubercular pyrimidine derivatives with a yet unexplored or speculative target, dividing the compounds according to their structural types.

Antitubercular 2-Pyrazolylpyrimidinones: Structure-Activity Relationship and Mode-of-Action Studies. J Med Chem 2021; 64:719-740.

Abstract
Phenotypic screening of a Medicines for Malaria Venture compound library against Mycobacterium tuberculosis (Mtb) identified a cluster of pan-active 2-pyrazolylpyrimidinones. The biology triage of these actives using various tool strains of Mtb suggested a novel mechanism of action. The compounds were bactericidal against replicating Mtb and retained potency against clinical isolates of Mtb. Although selected MmpL3 mutant strains of Mtb showed resistance to these compounds, there was no shift in the minimum inhibitory concentration (MIC) against a mmpL3 hypomorph, suggesting mutations in MmpL3 as a possible resistance mechanism for the compounds but not necessarily as the target. RNA transcriptional profiling and the checkerboard board 2D-MIC assay in the presence of varying concentrations of ferrous salt indicated perturbation of the Fe-homeostasis by the compounds. Structure-activity relationship studies identified potent compounds with good physicochemical properties and in vitro microsomal metabolic stability with moderate selectivity over cytotoxicity against mammalian cell lines.
