A series of coumarin‐thiourea hybrids (4 a–o) has been synthesized, and the compounds have been evaluated against the tumour associated transmembrane isoform, human (h) carbonic anhydrase (CA) hCA IX and the less‐explored cytosolic isoform, hCA XIII. All compounds exhibited potent inhibition of both isoforms, with KI values of <100 nM against hCA IX. Compound 4 b was the best inhibitor (KI=78.5 nM)
一系列香豆素-硫脲杂种(4 - ö)已被合成,并且该化合物已经针对所述肿瘤相关跨膜同种型,人(h)碳酸酐酶(CA)HCA IX和-探索少胞质同种型,HCA评价十三。所有化合物都表现出对两种异构体的有效抑制作用,对 hCA IX 的K I值 <100 nM。化合物4b是最好的抑制剂(K I =78.5 nM)。所有化合物均在低纳摩尔至亚微摩尔范围内抑制 hCA XIII,其中化合物4b再次显示出最佳抑制作用(K I =76.3 nM)。与化合物4b 作为先导,可能会开发出更具选择性的 hCA IX 和 hCA XIII 抑制剂或双重 hCA IX/XIII 抑制剂。
