Regiospecific and highly stereoselective electrophilic addition to furanoid glycals: synthesis of phosphonate nucleotide analogs with potent activity against HIV
摘要:
Regiospecific and highly stereoselective electrophilic addition to furanoid glycals has been used as a key step in the synthesis of phosphonate isosteres of nucleoside monophosphates. Using this methodology, phosphonate analogues of 1 (ddA), 4 (d4T), and 5 (d4A) monophosphates have been prepared. Present studies have also led to the development of a scheme for the synthesis of the phosphonate isostere of adenosine monophosphate. Despite the acetal structure, phosphonate derivatives 27 and 28 were substantially more acid stable than the corresponding nucleosides 1 and 5 with respect to glycosidic bond cleavage. The phosphonates 22 and 27 exhibited a potent antiretroviral activity comparable to that of 4 (d4T).
Isosteric triphosphonate analogues of dNTP: Synthesis and substrate properties toward various DNA polymerases
摘要:
Isosteric triphosphonate derivatives of 2',3'-dideoxy-2',3'-didehydroadenosine and 3'-deoxy-2',3'-didehydrothymidine and their beta,gamma-substituted analogues were synthesized. Their substrate properties toward a number of reverse transcriptases of the human immunodeficiency and avian myeloblastosis viruses, human DNA polymerases alpha and beta, and the Klenow fragment of Escherichia coli DNA polymerase I were studied.

A series of nucleoside phosphonate reverse transcriptase (RT) inhibitors have been synthesized and their anti-HIV activity and resistance profiles evaluated. The most potent analog [5-(6-amino-purin-9-yl)-2,5-dihydro-furan-2-yloxymethyl]-phosphonic acid (d4AP) demonstrated a HIV EC50 = 2.1 mu M, and the most favorable resistance profile against HIV-1 variants with K65R, M184V or multiple thymidine analog mutations in RT.
