  3,5-Di-(tert-Butyl)-6-fluoro-cycloSal-d4TMP-一种掩蔽基团显着改善的前核苷酸

  摘要：

  已经开发了一种新的、显着改进的 cycloSal 掩蔽组。这个新组结合了四种理想的特性，并已连接到抗 HIV 药物 2',3'-dideoxy-2',3'-didehydrothymidine (d4T, 1) 上以产生 3,5-(di-tert-butyl) -6-氟-环Sal-d4TMP (2i)。这种磷酸三酯具有合理的化学半衰期，高度选择性地释放 d4TMP，对丁酰胆碱酯酶 (BChE) 的抑制作用很差（如果有的话），并实现了 TK 旁路。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)

  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.
