  Potential Multifunctional Inhibitors of HIV-1 Reverse Transcriptase. Novel [AZT]-[TSAO-T] and [d4T]-[TSAO-T] Heterodimers Modified in the Linker and in the Dideoxynucleoside Region

  摘要：

  In an attempt to combine the anti-HIV-inhibitory capacity of nucleoside reverse transcriptase (RT) inhibitors (NRTI) and non-nucleoside RT inhibitors (NNRTI), several heterodimer analogues of the previously reported [AZT]-(CH(2))(3)-[TSAO-T] prototype have been prepared. In these novel series, other NRTIs, an expanded range of linkers with different conformational freedom and other attachment sites for these linkers on the base part of the NRTI analogue have been explored. Moreover, in order to circumvent the dependence of the NRTI moiety of the heterodimer an activation by cellular nucleoside kinases, novel heterodimers in which the NRTI is bearing a masked monophosphate group at the 5'-position are described. Among the novel heterodimers, several derivatives show a potent anti-HIV-1 activity, which proved comparable, or even superior, to that of the AZT heterodimer prototype. The nature of the NRTI was important far the eventual anti-HIV-1 activity. In particular, the d4T heterodimer derivative containing a propyl linker between the N-3 positions of the base of TSAO-T and d4T was similar to 5- to 10-fold more inhibitory to HIV-1 than the corresponding AZT heterodimer prototype.

• Aryl phosphate derivatives of d4T having anti-HIV activity
  申请人：Parker Hughes Institute

  公开号：US06350736B1

  公开（公告）日：2002-02-26

  Aryl phosphate derivatives of d4T with para-bromo substitution on the aryl group show markedly increased potency as anti-HIV agents without undesirable levels of cytotoxic activity. In particular, these derivatives are potent inhibitors of HIV reverse transcriptase. In a preferred aspect of the present invention, the phosphorus of the aryl phosphate group is further substituted with an amino acid residue that may be esterified or substituted, such as a methoxy alaninyl group.

  d4T的芳基磷酸酯衍生物，在芳基上对位溴取代，显示出明显增强的抗HIV活性，而无不良水平的细胞毒活性。特别是，这些衍生物是HIV反转录酶的强效抑制剂。在本发明的首选方面，芳基磷酸酯基的磷进一步取代为氨基酸残基，该残基可以酯化或取代，如甲氧基丙氨基基团。

  Changing the nucleoside group of a series of phosphoramidate derivatives affects the enzyme mediated hydrolysis rate of the compounds. d4T and AZT-substituted analogs were activated by enzymes such as lipases, esterases, and proteases. On the other hand, 3dT-substituted derivatives were comparatively less prone to hydrolysis under similar experimental conditions. From the experimental results, we propose that-the most preferable nucleoside group for enzyme activation is d4T rather than AZT or 3dT. Additionally, we also observed that depending on the enzymes used the chiral selectivity of the enzymes for the phosphorus center of these phosphoramidate derivatives differed, demonstrating the importance of the nucleoside structure for this class of compounds.
