  (Z)- and (E)-[2-Fluoro-2-(hydroxymethyl)cyclopropylidene]methylpurines and -pyrimidines, a New Class of Methylenecyclopropane Analogues of Nucleosides:  Synthesis and Antiviral Activity

  摘要：

  The Z- and E-isomers of fluoromethylenecyclopropane analogues 11a-d and 12a-d were synthesized, and their antiviral activities were evaluated. The purine (Z,E)-methylenecyclopropane carboxylates 13 and 24 were selectively fluorinated using lithium diisopropylamide, LiCl, and N-fluorobenzenesulfonimide to give (Z,E)-fluoroesters 22 and 25. Reduction with LiBH4 or diisobutylaluminum hydride gave after chromatographic separation Z-isomers 11a and 11e and E-isomers 12a and 12e. The O-demethylation of 11e and 12e afforded guanine analogues 11b and 12b. Fluorination of (Z,E)-cytosine and thymine esters 15 and 16 afforded (Z,E)-fluoroesters 26 and 27, which were resolved before the reduction to analogues 11c and 11d and 12c and 12d. Adenine Z-isomer 11a was the most effective against Towne and AD 169 strains of human cytomegalovirus (HCMV, EC50 3.6 and 6.0 muM, respectively), but it was less effective against murine virus (MCMV, EC50 69 muM). Thymine Z-isomer 11d was effective against HSV-1 in BSC-1 cells (ELISA, EC50 2.5 muM) but inactive against HSV-1 or HSV-2 in Vero or HFF cells. All of the analogues with the exception of 12d were effective at least in one of the assays against Epstein-Barr virus (EBV) in Daudi or H-1 cells in a micromolar or submicromolar range. Cytosine and thymine Z-isomers 11c and 11d were active against varicella zoster virus (VZV) with EC50 0.62 muM. Adenine Z- and E-isomers 11a and 12a were effective against HIV-1 in MT-2 or MT-4 cells with EC50 12-22 and 2.3-7.6 muM, respectively, whereas only 12a was effective against hepatitis B virus (HBV) with EC50 15 muM. Analogues 11a and 12a were weak substrates for adenosine deaminase.
