Twenty-two 4-aryl/alkyl-1-(diphenylacetyl)thiosemicarbazides were synthesized and their in vitro antibacterial
potency was evaluated. 4-(4-Chlorophenyl)-1-diphenylacetylthiosemicarbazide showed comparable activity to control antibacterial
ampicillin against Gram-positive species with MICs range 3.91-15.63 µg/mL. The compound was also tested
for its cytotoxicity against L929 cell line using the MTT assay technique. The results of antibacterial activity and toxicity
test indicated that it display antibacterial activity at non-cytotoxic concentrations. Finally, some structural and electronic
parameters have been determined in hope to get insight into different biological activity of closely related isomers.
合成了二十二种4-芳基/烷基-1-(二苯乙酰)
硫脲,评估了它们的体外抗菌活性。4-(4-
氯苯基)-1-二苯乙酰
硫脲对革兰阳性菌的抗菌活性与对照抗菌药物
青霉素相当,最小抑菌浓度(MIC)范围为3.91-15.63 µg/mL。该化合物还采用M
TT法测试了其对L929
细胞系的细胞毒性。抗菌活性和毒性测试的结果表明,其在非细胞毒性浓度下表现出抗菌活性。最后,为了深入了解相关同分异构体的不同
生物活性,确定了一些结构和电子参数。
