Described herein are two series (twelve compounds each) of very closely related guanidinium‐based receptors and their ability to catalyze hydrolytic cleavage of a unique RNA substrate – oligo‐dT flanked trans‐Activation Responsive region of the HIV‐1 mRNA, TAR RNA. The significant difference in activities of otherwise very similar compounds is discussed, and direct and indirect evidences supporting
本文描述的是两个系列非常密切相关的基于胍盐-受体(各12种化合物)和其催化的唯一RNA底物的水解裂解能力-寡-dT侧翼吨失败者-甲ctivation ř esponsive HIV-1的mRNA的区域,TAR RNA。讨论了其他方面非常相似的化合物在活性上的显着差异,并提供了支持我们解释的直接和间接证据。结果表明,只需对相对较弱的催化剂的结构进行少许改动即可实现催化效率的提高,并且关键的功能可能是阴离子结合能力和质子给体能力之间的精细校准相互作用。
