摘要：

A diverse set of 4,7-dihydro-[1,2,3]thiadiazolo[5,4-b]pyridine-6-carboxamides 4(a–o) was synthesized via a one-pot reaction of 5-amino-[1,2,3]thiadiazole, various aromatic aldehydes, and different acetoacetanilides, using glacial acetic acid. The resulting compounds were obtained in moderate to good yields. All the newly synthesized compounds were evaluated for their antimicrobial activity. Among them, compound 4 e demonstrated superior efficacy against the Salinivibrio proteolyticus strain of Gram-negative bacteria compared to ciprofloxacin. Compound 4 d exhibited the highest potency against the fungal strain Candida albicans, surpassing amphotericin B. The physicochemical characteristics of 4 d and 4 e were assessed. According to docking analysis, DHTDAPy 4 e shows a higher binding affinity of −7.2 kcal/mol in the binding cavity of the receptor. These findings illustrate the safety, tolerability, and potency of the newly synthesized DHTDAPy compounds against fungal and bacterial infections. © 2024 Wiley-VCH GmbH.
