碳酸酐酶异构体 IX 和 XII 在缺氧肿瘤细胞中过度表达,调节细胞增殖、侵袭和转移等多种生理过程,导致癌症的发生和扩散。选择性抑制这些酶是一种有前途的抗癌治疗策略。香豆素衍生物被认为是这些异构体的选择性和有效抑制剂。本研究报告了 6-氨基香豆素磺酰胺和肟醚衍生物通过氯乙酰基部分分别与哌嗪和哌啶酮连接,显示出对人碳酸酐酶 (hCA) IX 和 XII 的选择性抑制,K i 范围为 0.51 至 1.18 µM和0.89–4.43 µM。磺酰胺衍生物8a对 hCA IX 和 XII 表现出亚微摩尔抑制, K i分别为 0.89 和 0.51 µM,而肟醚衍生物表现出比磺酰胺更低的活性,化合物5n抑制 hCA IX 和 hCA XII,K i分别为 1.055 和 0.70分别为μM。上述结果证明了这些衍生物作为碳酸酐酶IX和XII的选择性、有效抑制剂的潜力,并为进一步优化和开发作为有效抗癌药
Benzimidazolium-based chemosensors: selective recognition of H<sub>2</sub>PO<sub>4</sub><sup>−</sup>, HP<sub>2</sub>O<sub>7</sub><sup>3−</sup>, F<sup>−</sup> and ATP through fluorescence and gelation studies
Benzimidazolium-based receptors 1 and 2 exhibit sensing properties towards different anions such as H2PO4−, HP2O73− and F− under identical condition. Experimental results are correlated with the theoretical findings.

Despite recent progress in antithrombotic therapy, there's still an unmet medical need for safe and orally available anticoagulants. Encouraged by the marked antithrombotic and anticoagulant activities of some coumarin derivatives, twenty-three new N-coumarinyl-4-amidinobenzamides 4a-f and 6-heterocycle substituted coumarin derivatives 5, 6a,b, 10a-e, 12a-e and 14a-d were synthesized and evaluated for their in vivo antithrombotic activity. The most active congeners were the unsubstituted amidine 4a (36.5 s), coumarinyl oxadiazole 5 (42.3 s), bis coumarinyl oxadiazole 6b (37.8 s) and coumarinyl pyrazole 10b (38.5 s) that presented prothrombin time (PT) values comparable to the reference drug warfarin (42.3 s). Furthermore, docking studies were undertaken to gain insight into the possible binding mode of these compounds with the coagulation factor Xa (FXa) binding site. (C) 2013 Elsevier Inc.
