Transition state mimicry is one of the most powerful concepts in enzyme inhibitor design and has led to the development of catalytic antibodies. Transition state analogs are compounds with a fixed shape that resemble the geometry and charge distribution of the transition state of a given reaction. Stabilization of a transition state like conformation is most often achieved by incorporating a ring system
过渡态模拟是酶抑制剂设计中最强大的概念之一,并导致了催化抗体的开发。过渡态类似物是具有固定形状的化合物,类似于给定反应的过渡态的几何形状和电荷分布。过渡态(如构象)的稳定通常是通过将环系统结合到类似物中来实现的。我们在此表明,阻转异构可用作强制执行过渡态(如构象)的新原理。阻转异构与结构受限分子的立体异构体的存在有关,这是由于围绕单键的冻结旋转,例如在联萘酚中。由于围绕 C(1)-C(亚甲基) 单键的冻结旋转,1-氨基甲基萘衍生物 1 表现出阻转异构现象,使二面角 θ[C(2)-C(1)-C(亚甲基)-N] 接近 90°。化合物 1 模拟了 1,4-二氢喹啉 4 和丙酮之间氢化物转移的过渡态。
