  Synthesis and biological activity of sinefungin analogs

  摘要：

  A series of nucleosides (2-4) that derive from adenosine by chain extension at the 5'-end have been synthesized starting from the known phosphonate 7. The latter was first combined with 4-pentenal to give 8, which underwent chemical manipulations to provide triacetate 11, which was found suitable for the adenylation step. Further transformations, among them the Hofmann degradation of the amide group of compound 13, and final deprotection gave nucleosides 2-4. They were considered as analogues of sinefungin (1) and tested for their antileishmanial activity together with compounds 5 and 6, which were obtained independently. All the modifications with respect to sinefungin resulted in nearly complete loss of growth inhibitory activity. These results indicate that the 9' terminal amino and carboxyl groups are necessary for the activity and that the presence of the amino group at C-6' is not sufficient to maintain the antileishmanial effect. Some of the analogues however could antagonize or reverse the inhibitory activity of sinefungin (1).
