Design, synthesis, in silico, and in vitro evaluation of 3-phenylpyrazole acetamide derivatives as antimycobacterial agents. Arch Pharm (Weinheim) 2020; 354:e2000349. [PMID: 33351199 DOI: 10.1002/ardp.202000349] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Revised: 11/12/2020] [Accepted: 11/21/2020] [Indexed: 11/12/2022]
Abstract
Mycobacterium tuberculosis (Mtb) is one of the most dangerous pathogens affecting immunocompetent and immunocompromised patients worldwide. Novel molecules, which are efficient and can reduce the duration of therapy against drug-resistant strains, are an urgent unmet need of the hour. In our current study, a series of new 2-(3-phenyl-1H-pyrazol-1-yl)acetamide and N'-benzylidene-2-(3-phenyl-1H-pyrazol-1-yl)acetohydrazide derivatives were designed, synthesized, and evaluated for their antimycobacterial potential. The biological evaluation revealed that 6b, 6m, 6l, 7a, and 7k exhibited selective and potent inhibitory activity against Mtb. Furthermore, compounds 6m and 7h were found to be nontoxic to Vero cells with CC50 of greater than 20 and 80 mg/ml, respectively, and exhibited promising selectivity indices (SI) of greater than 666 and 320, respectively. All derivatives exhibited excellent ADME (absorption, distribution, metabolism, and excretion) properties in silico. Also, all the derivatives were found compliant with Lipinski's rule of five, showing their druggability profile. Molecular docking insights of these derivatives have shown outstanding binding energies on the mycobacterial membrane protein large transporters. These results indicate that this scaffold may lead to a potential antimycobacterial drug candidate in the discovery of antitubercular agents.

[PMID: 35539945 PMCID: PMC9080941 DOI: 10.1039/c8ra03761b] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2018] [Accepted: 06/03/2018] [Indexed: 11/21/2022] Open
Abstract
A practically simple, mild and efficient method is developed for the synthesis of N-substituted ureas by nucleophilic addition of amines to potassium isocyanate in water without organic co-solvent. Using this methodology, a variety of N-substituted ureas (mono-, di- and cyclic-) were synthesized in good to excellent yields with high chemical purity by applying simple filtration or routine extraction procedures avoiding silica gel purification. The developed methodology was also found to be suitable for gram scale synthesis of molecules having commercial application in large volumes. The identified reaction conditions were found to promote a unique substrate selectivity from a mixture of two amines.

Abstract
One-third of the world's population infected tuberculosis (TB), and more than 1 million deaths annually. The co-infection between the mainly pathogen Mycobacterium tuberculosis (MTB) and HIV, and the incidence of drug-resistant TB, multi-drug resistant TB, extensively drug-resistant TB as well as totally drug-resistant TB have further aggravated the mortality and spread of this disease. Thus, there is an urgent need to develop novel anti-TB agents against both drug-susceptible and drug-resistant TB. The wide spectrum of biological activities and successful utilization of pyrazole-containing drugs in clinic have inspired more and more attention towards this kind of heterocycles. Numerous of pyrazole-containing derivatives have been synthesized for searching new anti-TB agents, and some of them showed promising potency and may have novel mechanism of action. This review aims to outline the recent achievements in pyrazole-containing derivatives as anti-TB agents and their structure-activity relationship.
