Exploration of 1,3,5-trisubstituted pyrazoline derivatives as human carbonic anhydrase inhibitors: Synthesis, biological evaluation and in silico studies.

The human carbonic anhydrase (hCA) IX and XII isoforms are overexpressed in hypoxic conditions, contributing to cancer. Lack of isoform selectivity has been one of the main challenges associated with the existing drugs targeting hCAs. Hence, the development of alternative approaches, such as tail approach to develop more selective hCA IX and XII inhibitors is need of the hour.

Synthesis and biological evaluation of new naphthalimide-thiourea derivatives as potent antimicrobial agents active against multidrug-resistant and .

The emergence of antibiotic resistance to and , particularly MRSA, VRSA, and drug-resistant tuberculosis, poses a serious threat to human health. Towards discovering new antibacterial agents, we designed and synthesized a series of new naphthalimide-thiourea derivatives and evaluated them against a panel of bacterial strains consisting of , , , , and various mycobacterial pathogens. Compounds 4a, 4l, 4m, 4n, 4q, 9f, 9l, 13a, 13d, 13e, 17a, 17b, 17c, 17d, and 17e demonstrated potent antibacterial activity against with MIC 0.

6-Aminocoumarin oxime-ether/sulfonamides as selective hCA IX and XII inhibitors: Synthesis, evaluation, and molecular dynamics studies.

Carbonic anhydrase isoforms IX and XII are overexpressed in hypoxic tumor cells regulating various physiological processes such as cell proliferation, invasion, and metastasis, resulting in the onset and spread of cancer. Selective inhibition of these enzymes is a promising strategy for anticancer therapy. Coumarin derivatives were identified as selective and potent inhibitors of these isoforms.

A comprehensive review on potential therapeutic inhibitors of nosocomial Acinetobacter baumannii superbugs.

Acinetobacter baumannii, a Gram-negative, glucose non-fermentative coccobacilli are responsible for causing a wide range of opportunistic nosocomial infections, thus listed as a WHO "critical priority pathogen", for which identification and development of new antibacterial agents are an urgent unmet medical need. The current review attempts to present an overview of various mechanisms (enzymatic and non-enzymatic), virulence factors responsible for A. baumannii resistance.

Design, synthesis, SAR, and biological evaluation of saccharin-based hybrids as carbonic anhydrase inhibitors.

Saccharin is a cyclic secondary sulfonamide, which is a selective inhibitor of the tumor-associated carbonic anhydrase (CA; EC 4.2.1.

Synthesis and Biological Evaluation of Coumarin Carboxamides as Selective and Potent Inhibitors of Carbonic Anhydrases IX and XII.

Background: Carbonic anhydrases (CAs, EC 4.2.1.

Synthesis and Biological Evaluation of Coumarin-Linked 4-Anilinomethyl-1,2,3-Triazoles as Potent Inhibitors of Carbonic Anhydrases IX and XIII Involved in Tumorigenesis.

A series of coumarin-linked 4-anilinomethyl-1,2,3-triazoles (-) was synthesized via a molecular hybridization approach, through carbon C-6 of the coumarin moiety. The synthesized compounds were evaluated for their inhibition of carbonic anhydrase (CA) isoforms I, II, IX and XIII. CAs IX and XIII were selectively inhibited over the off-target isoforms I and II.

Coumarin-Thiourea Hybrids Show Potent Carbonic Anhydrase IX and XIII Inhibitory Action.

A series of coumarin-thiourea hybrids (4 a-o) has been synthesized, and the compounds have been evaluated against the tumour associated transmembrane isoform, human (h) carbonic anhydrase (CA) hCA IX and the less-explored cytosolic isoform, hCA XIII. All compounds exhibited potent inhibition of both isoforms, with K values of <100 nM against hCA IX. Compound 4 b was the best inhibitor (K =78.
