A newclass of amido linked azolyl thiophenes was prepared from the synthetic intermediates azolyl amines and 5‐chlorothiophene‐2‐carbonyl chloride adopting conventional and ultrasonication methodologies. It was observed that the reaction took place in shorter reaction times with higher yields under ultrasonication. The structures of the synthesized compounds were characterized by spectral parameters
A new class of azolyl pyrimidines linked by diamino sulfone moiety was prepared and studied their antimicrobialactivity. Chloro‐substituted and nitro‐substituted thiazolyl pyrimidines (9c and 9e) showed excellent antibacterial activity against Bacillus subtilis, while imidazolyl pyrimidines (10c and 10e) exhibited promising antifungal activity against Aspergillus niger.
In this work, a series of 2-substituted-thio-N-(4-substituted-thiazol/1H-imidazol-2-yl)acetamide derivatives were developed as β-secretase (BACE-1) inhibitors. Supported by docking study, a small library of derivatives were designed, synthesized and biologically evaluated in vitro. In addition, the selected compounds were tested with affinity (KD) towards BACE-1, blood brain barrier (BBB) permeability
Compounds 22c and 24c also showed low MICs against Aspergillus niger, equal to the standard drug, ketoconazole. The molecularproperties of the synthesized molecules were studied to identify druglikeness properties of the target compounds. On the basis of molecularpropertiesprediction, 19a, 19b, 20b, 20c, 21a–c, 22b, 22c, and 23a–c can be treated as drug candidates.
