of the synthesized compounds. In vitro biological assay against four different human carbonic anhydrases took place and based on the results, SAR study was illustrated and selectivity indexes were discussed. Compounds 4g and 8a exhibited the best inhibitory activity among the target compounds with values (hCAIX: KI = 71.2 nM, hCAXII: KI = 22.5 nM), (hCAIX: KI = 34.3 nM, hCAXII: KI = 74.3 nM); respectively
据报道,几种吡唑-苯磺酰胺可作为人类碳酸酐酶抑制剂。在这项研究工作中,基于尾部方法设计,报道了亚芳基扩展的 5-氧代-吡唑苯磺酰胺 ( 4a-i )、( 8a-d ) 和 ( 10a-e ) 的设计。除了报道的合成程序和通过不同分析程序的确认之外,还采用 DFT 研究来确认合成化合物的Z构象异构体。对四种不同的人碳酸酐酶进行了体外生物学测定,并根据结果阐述了SAR研究并讨论了选择性指标。化合物4g和8a在目标化合物中表现出最好的抑制活性,其值为 (hCAIX: K I = 71.2 nM, hCAXII: K I = 22.5 nM),(hCAIX: K I = 34.3 nM, hCAXII: K I = 74.3 nM) ;分别。在常氧和低氧条件下,对两种具有 hCA 同种型表达性质的不同癌细胞系进行细胞测定。与常氧条件下的参考药物阿霉素(IC 50 = 4.34 µM)相比,化合物4g对
