A series of new 4-(3-(4-substitutedphenyl)-3a,4-dihydro-3H-indeno[1,2-c]pyrazol-2-yl) benzenesulfonamides (7-12) was synthesized starting from 2-(4-substitutedbenzylidene)-2,3-dihydro-1H-inden-1-one (1-6) and 4-hydrazinobenzenesulfonamide. The substituted benzaldehydes from which the key intermediate was prepared by introducing 2- or 4-substituents such as fluorine, hydroxy, methoxy, or the 3,4,5-trimethoxy
从2-(-)开始合成了一系列新的4-(3-(4-取代苯基)-3a,4-二氢-3H-茚并[1,2-c]吡唑-2-基)苯磺酰胺(7-12)。 4-取代的亚苄基)-2,3-二氢-1H-茚-1-酮(1-6)和4-肼基苯磺酰胺。通过引入2-或4-取代基(例如氟,羟基,甲氧基或3,4,5-三甲氧基部分)可制备关键中间体的取代苯甲醛。测试了这些化合物的细胞毒性,肿瘤特异性和作为碳酸酐酶(CA,EC 4.2.1.1)抑制剂的潜力。3,4,5-三甲氧基和4-羟基衍生物表现出令人感兴趣的细胞毒性活性,这可能对进一步的抗肿瘤活性研究至关重要,而其中的某些磺酰胺类药物强烈抑制人(h)胞质亚型hCA I和II。
