Abstract
A series of 4-arylacetamido-2-amino- and 2-arylamino-1,3-thiazoles (4a–o) were synthesized in a single step in high yields from ω-bromoacetoacetanilides and thiourea/phenyl thioureas and were characterized by spectral and analytical methods. The compounds were evaluated for their in vitro antibacterial antifungal and antioxidant activities. In vitro antimicrobial evaluation of these compounds indicated their specificity towards Gram-positive species. p-Tolyl and m-chlorophenyl substituents on the arylamino moiety (compounds 4b and 4g) exhibited the lowest minimum inhibitory concentration values. The other compounds exhibited promising antimicrobial and moderate antioxidant activity.
一系列4-芳基乙酰胺基-2-氨基和2-芳胺基-1,3-噻唑(4a-o)在高产率下通过一步合成,从ω-溴乙酰苯胺基乙酰胺和硫脲/苯硫脲中合成,并通过光谱和分析方法进行表征。这些化合物被评估其体外抗菌、抗真菌和抗氧化活性。这些化合物的体外抗微生物评估表明它们对革兰氏阳性菌种具有特异性。芳胺基上的对甲苯基和间氯苯基取代基(化合物4b和4g)表现出最低的最小抑制浓度值。其他化合物表现出有希望的抗微生物和中等的抗氧化活性。
