A compound represented by general formula (I) (in the formula, all symbols are as described in the description) or a salt thereof has a potent nerve-protecting and/or -repairing activity, and therefore can be used as a therapeutic agent for neuropathy (e.g., chronic inflammatory demyelinating polyneuropathy, Guillain-Barre syndrome, periarteritis nodosa, allergic vasculitis, diabetic peripheral neuropathy, entrapment neuropathy, peripheral neuropathy associated with the administration of a chemotherapeutic drug, or peripheral neuropathy associated with Charcot-Marie-Tooth disease).
A conceptual extension of the cycloSal‐pronucleotide approach is presented. The characteristic feature of the new cycloSal‐derivatives of the anti‐HIV active nucleoside analogue d4T 1 is the incorporation of an enzymatically cleavable carboxylic ester moiety with the intention to trap the triesters inside cells (”lock‐in”‐concept). CycloSal‐triesters bearing different ester groups in the 3‐or 5‐position
介绍了环Sal-核苷酸方法的概念扩展。抗 HIV 活性核苷类似物 d4T 1 的新环盐衍生物的特征是掺入了可酶切的羧酸酯部分,目的是将三酯捕获在细胞内(“锁定”概念)。描述了在环Sal部分的3-或5-位带有不同酯基的环Sal-三酯。令人惊讶的是,只有乙酰基酯和乙酰丙酸酯在 CEM 细胞提取物中容易裂解,而烷基酯被发现是稳定的。尽管如此,在体外抗 HIV 检测中,大多数化合物实现了胸苷激酶旁路,从而证明它们至少充当核苷酸传递系统。†为了纪念和庆祝 Leroy B. Townsend 教授 70 岁生日。
