  Bis-cycloSal-d4T-monophosphates:  Drugs That Deliver Two Molecules of Bioactive Nucleotides

  摘要：

  Bis-cycloSal-d4T-monophosphates have been synthesized as potentially anti-HIV active "dimeric" prodrugs of 2',3'-dideoxy-2',3'-didehydrothymidine monophosphate (d4TMP). These pronucleotides display a mask-drug ratio of 1:2, a novelty in the field of pronucleotides. Both bis-cycloSal-d4TMP 6 and bis-5-methyl-cycloSal-d4TMP 7 showed increased hydrolytic stability as compared to their "monomeric" counterparts and a completely selective hydrolytic release of d4TMP. The hydrolysis pathway was investigated via P-31 NMR spectroscopy. Moreover, due to the steric bulkiness, compound 6 already displayed strongly reduced inhibitor potency toward human butyrylcholinesterase (BChE), while compound 7 turned out to be devoid of any inhibitory activity against BChE. Partial separation of the diastereomeric mixture of 6 revealed strong dependence of the pronucleotides' properties on the stereochemistry at the phosphorus centers. Both 6and 7 showed good activity against HIV-1 and HIV-2 in wild-type CEM cells in vitro. These compounds were significantly more potent than the parent nucleoside d4T 1in HIV-2-infected TK-deficient CEM cells, indicating an efficient TK-bypass.

  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.

• NOVEL <i>CYCLOSAL</i> NUCLEOTIDES WITH REDUCED INHIBITORY POTENCY TOWARD HUMAN BUTYRYLCHOLINESTERASE
  作者：C. Ducho、S. Jessel、N. Gisch、J. Balzarini、C. Meier

  DOI：10.1081/ncn-200061791

  日期：2005.4.1

  Two novel cycloSal-d4T monophosphates (d4TMPs) with increased steric demand have been synthesized via a new synthetic route. While 3-cyclohexyl-cycloSal d4TMP did not show a significantly reduced inhibitory potency toward human butrylylcholinesterase, the opposite was the case for the second novel pronucleotide, bi-(cycloSal-d4TMP).
