current study, unique series of coumarin sulfonate and sulfamate derivatives were synthesized. Their selectivity and inhibitory activity against glaucoma and cancer-associated CAs (hCA II, IX, and XII) were evaluated compared to standard acetazolamide. In addition, the cytotoxic effects of the synthesized compounds on colorectal carcinoma (HCT116) were examined. Generally, structure-activity relationship
在当前的研究中,合成了独特的系列香豆素磺酸盐和氨基磺酸盐衍生物。与标准乙酰唑胺相比,评估了它们对青光眼和癌症相关 CA(hCA II、IX 和 XII)的选择性和抑制活性。此外,还检查了合成化合物对结直肠癌(HCT116)的细胞毒性作用。一般来说,构效关系 (SAR) 分析表明,由于经典的抑制作用模式,带有锌结合基团 (ZBG) 氨基磺酸二甲酯 (4a-c) 的有效抑制剂对三种亚型缺乏选择性。在非氨基磺酸盐香豆素衍生物中掺入芳基或氟芳基砜部分分别将选择性转向与癌症相关的异构体 XII 和 IX。对氟取代衍生物 3c 的 IC 50 值为 0.62 µM,对 hCA IX 表现出优异的活性和选择性,而苯砜衍生物 3b 对 hCA XII 表现出选择性,IC 50 值为0.56 µM。此外,香豆素与乙基砜的衍生物(3e、3i 和 6a)对 CAII 具有出色的选择性。还对选择性的、有效的化合物
