Investigation of 3-sulfamoyl coumarins against cancer-related IX and XII isoforms of human carbonic anhydrase as well as cancer cells leads to the discovery of 2-oxo-2H-benzo[h]chromene-3-sulfonamide – A new caspase-activating proapoptotic agent

Herein we report the synthesis of a set of seventeen 3-sulfonamide substituted coumarin derivatives. Prepared compounds were tested in vitro for inhibition of four physiologically relevant isoforms of the metalloenzyme human carbonic anhydrase (hCA, EC 4.2.1.1). Several coumarin sulfonamides displayed low nanomolar KI values against therapeutically relevant hCA II, IX, and XII, whereas they did not
在此,我们报告了一组 17 种 3-磺酰胺取代香豆素衍生物的合成。体外测试制备的化合物对金属酶人碳酸酐酶 ( h CA, EC 4.2.1.1)的四种生理相关同种型的抑制。几种香豆素磺酰胺对治疗相关的h CA II、IX 和 XII显示出低纳摩尔 K I值,而它们不能有效抑制hCA I.这些化合物中的一些对RT4人膀胱癌,尤其是A431人表皮样癌细胞系发挥浓度依赖性抗增殖作用。同时,非致瘤性 hTERT 永生化人包皮成纤维细胞系 Bj-5ta 的生存能力不受所得衍生物的显着影响。有趣的是,化合物10q(2-oxo-2 H - benzo[ h ]chromene-3-sulfonamide)显示出对 A431 细胞生长的显着且选择性的剂量依赖性抑制,具有低纳摩尔 IC 50值。我们证明了10q具有与癌细胞中 caspase 3/7 激活相关的浓度依赖性细胞凋亡诱导活性。由于所讨论的碳酸酐酶
