potential inhibitors (acylhydrazones) generated from five aldehydes and five hydrazides and used DCC to identify the best binder(s). After addition of the aspartic protease endothiapepsin, we characterized the protein‐bound library member(s) by saturation‐transfer difference NMR spectroscopy. Cocrystallization experiments validated the predicted binding mode of the two most potent inhibitors, thus demonstrating
基于结构的设计(SBD)可用于设计和/或优化针对生物靶标的新抑制剂。尽管很少使用从头开始的SBD,但有关SBD的大多数报告都在处理初始匹配的优化。动态组合化学(DCC)已成为鉴定生物活性配体的有力策略,因为它使靶标能够指导其最强结合剂的合成。我们设计了一个由五种醛和五种酰肼生成的潜在抑制剂(酰基hydr)的文库,并使用DCC来确定最佳的粘合剂。加入天冬氨酸蛋白酶内皮抑素后,我们通过饱和转移差NMR光谱对蛋白质结合的文库成员进行了表征。共结晶实验验证了两种最有效抑制剂的预测结合方式,
