Furagin and its derivatives possess inhibitory activity on human (h) carbonicanhydrases (CA, EC 4.2.1.1), some of which are highly expressed in various tissues and malignancies (hCA IX/XII). Furagin exhibited good hCA IX and XII inhibition with KIs of 260 and 57 nM, respectively. It does not inhibit off-target CA I and poorly inhibited CA II (KI = 9.6 μM).

临床上使用的抗生素富拉根及其衍生物对人(h)碳酸酐酶具有抑制活性(CA,EC 4.2.1.1),其中一些在各种组织和恶性肿瘤中高度表达(hCA IX / XII)。Furagin表现出良好的hCA IX和XII抑制作用,KI分别为260和57 nM。它不会抑制脱靶CA I,并且抑制CA II的能力较弱(KI = 9.6μM)。一些合成的具有氨基乙内酰脲部分作为锌结合基团的Furagin衍生物对KIs的抑制作用较弱,对KI的抑制作用分别为350至7400和150至5600 nM,对CA IX / XII的抑制作用良好。对接和分子动力学模拟表明,与癌症相关的CA IX / XII对CA II的选择性是由于CA IX / XII中强的H键相互作用,涉及朝向活性位点疏水区域的尾巴。
