discovery approach to the synthesis and identification of small molecule inhibitors of bovine carbonic anhydrase II (bCA II) is described. The classical bCA II recognition fragment is an aromatic sulfonamide (ArSO2NH2) moiety. This fragment was incorporated into a scaffold building block, which was subsequently derivatized by dynamic combinatorial chemistry utilizing alkene cross metathesis as the
描述了一种基于片段的药物发现方法,用于合成和鉴定牛碳酸酐酶II(bCA II)的小分子抑制剂。经典的bCA II识别片段是芳族磺酰胺(ArSO2NH2)部分。将该片段掺入支架构件中,随后通过利用烯烃交叉复分解作为可逆反应的动态组合化学将其衍生化。然后进行针对bCA II的筛选,结果可以确定包含ArSO2NH2片段的交叉复分解产物的相对bCA II结合亲和力。bCA II竞争性结合试验使用代表性数量的纯化合物验证了这些结果。筛选结果,无需事先分离出活性成分,与纯化合物的平衡解离常数(K(i)'s)完全一致。这些化合物中的一些表现出在低纳摩尔范围内的K(i)。在动态组合化学的这种药物发现应用中,非均相催化被证明是非常有效的。
