Halogen bonding triggers activity: Increasing binding affinity was observed for a series of covalent human Cathepsin L inhibitors by exchanging an aryl ring H atom with Cl, Br, and I, which undergo halogen bonding with the CO group of Gly61 in the S3 pocket of the enzyme. Fluorine, in contrast, strongly avoids halogen bonding (see scheme). The strong distance and angle dependence of halogen bonding
卤素键触发活性:通过将芳环H原子与Cl,Br和I交换,可以观察到一系列共价的人组织蛋白酶L抑制剂的结合亲和力增加,Cl,Br和I与S3口袋中的Gly61的CO基团进行卤素键合酶。相反,氟强烈避免卤素键(参见方案)。卤素键的强距离和角度依赖性已被证实适用于生物系统。
