NMI-SO 2Cl 2-Mediated Amide Bond Formation: Facile Synthesis of Some Dihydrotriazolopyrimidine Amide Derivatives as Potential Anti-Inflammatory and Anti-Tubercular Agents. Pharmaceuticals (Basel) 2024; 17:548. [PMID: 38794119 PMCID: PMC11123900 DOI: 10.3390/ph17050548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 04/17/2024] [Accepted: 04/20/2024] [Indexed: 05/26/2024] Open
Abstract
Facile access to some novel biologically relevant dihydrotriazolopyrimidine carboxylic acid-derived amide analogues using NMI/SO2Cl2, and aromatic and aliphatic primary and secondary amines, is reported herein. The role of N-methylimidazole (NMI) as the base and sulfuryl chloride (SO2Cl2) as the coupling reagent has been effectively realized in accessing these molecules in good to excellent yields. The feasibility of the developed protocol has also been extended to the gram-scale synthesis of N-benzylbenzamide in a 75% yield from benzoic acid and benzyl amine. The newly synthesized compounds were tested via in vitro anti-inflammatory and anti-tubercular activity studies. The compounds 6aa and 6be were found to be the most active anti-inflammatory agents, whereas 6cb and 6ch were found to exhibit promising anti-tubercular potency when compared to other synthesized molecules. The structure-activity relationship (SAR) studies revealed the importance of the presence of electron-donating functionalities in enhancing the anti-inflammatory potential of the newly synthesized molecules. However, the presence of electron-withdrawing substituents was found to be significant for improving their anti-tubercular potency.

Abstract
Pyrazolotriazolopyrimidines are an important class of nitrogen-containing heterocycles
that can act as a charismatic target and exhibit diverse pharmacological activities. These compounds
have received much attention because they are an attractive scaffold for the preparation of adenosine
receptor antagonists. Herein, we focus on an overview of the synthesis of these compounds with the
aim of assisting in the discovery of new pyrazolotriazolopyrimidine derivatives.
