  带有酯酶可切割位点的第二代cycloSal-d4TMP 前核苷酸——“诱捕”概念

  摘要：

  介绍了 cycloSal-核苷酸方法的扩展。将酶可裂解的酯/酰基基团连接到 cycloSal-d4TMP 三酯上应该允许这些化合物在裂解后被捕获在细胞内。在环Sal环系统的3-或5-位引入酯/酰基基团，并且在CEM细胞提取物的水解研究中观察到关于酯/酰基部分的惊人差异。虽然乙酰基酯和乙酰丙酸酯很容易裂解，但 cycloSal-d4TMP 酸的烷基酯证明对酶促裂解具有抗性。相比之下，AM-、POM- 和 POC-酰基在提取物中迅速裂解，产生 cycloSal-d4TMP 酸。还介绍了化合物对 HIV 的抗病毒活性。(© Wiley-VCH Verlag GmbH & Co.

  Interaction of cycloSal-Pronucleotides with Cholinesterases from Different Origins. A Structure−Activity Relationship

  摘要：

  A large number of cycloSal-nucleotide triesters 1-49 have been studied concerning their ability to inhibit cholinesterases of different origins as well as to inhibit HIV replication in cell culture. It was shown that none of the triesters showed inhibitory effects against human acetylcholinesterase (AChE; isolated enzyme) as well as against AChE from beef erythrocytes and calf serum. In contrast, inhibition of butyrylcholinesterase (BChE) has been observed for some triesters in human and mouse serum. cycloSal pronucleotides showed strong competitive inhibition with respect to the substrate acetylcholine chloride (K-i/K-m: similar to2 x 10(-5)) and acted by time-dependent irreversible inhibition of the human serum BChE. Detailed studies demonstrated that the inhibitory effect against BChE is dependent on the nucleoside analogue, the substitution pattern of the cycloSal-moiety, and particularly on the stereochemistry at the phosphorus atom. Structural requirements to avoid the inhibition of BChE by cycloSal-nucleotide triesters have been elucidated in the reported study.

• Second Generation of <i>cyclo</i>Sal‐Pronucleotides with Esterase‐Cleavable Sites: The ”Lock‐In”‐Concept

  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。

  A new class of d4TMP- cycloSal-pronucleotides bearing enzymatically cleavable amino acid esters is reported. These compounds are designed to trap the pronucleotide inside the cell by a fast conversion of a nonpolar ester group into a charged carboxylate. This should prevent efficient diffusion equilibrium across the cell membrane to the extracellular environment, leading to an intracellular accumulation

  报道了新型的带有酶可裂解的氨基酸酯的d4TMP-cycloSal-前核苷酸。这些化合物被设计为通过将非极性酯基团快速转变为带电荷的羧酸盐而将原核苷酸捕获在细胞内。这应防止跨细胞膜到细胞外环境的有效扩散平衡，导致化合物在细胞内的积累。该初始转化之后是核苷单磷酸酯（即d4TMP）的缓慢释放。该概念已通过在磷酸盐缓冲液，细胞提取物和人血清中的水解研究得到证明。这些研究表明，某些氨基酸酯修饰对细胞提取物转化的敏感性很高，从而导致带电荷的中间体快速释放，而在磷酸盐缓冲液中没有发现该修饰的切割。此外，还提出了针对艾滋病毒的抗病毒活性。
