  Acid-stable 2'-fluoro purine dideoxynucleosides as active agents against HIV

  摘要：

  2',3'-Dideoxy purine nucleosides have anti-HIV activity in vitro and the inosine analogue is being clinically evaluated. The instability of these compounds toward acidic conditions complicates oral administration. The effect of the addition of a fluorine atom to the 2'-position was investigated by preparing the fluorine-containing 2'-erythro and 2'-threo isomers of ddA and the threo isomer of ddI. All fluorine-containing compounds were indefinitely stable to acidic conditions which completely decomposed ddI (1) and ddA (2) in minutes. While the fluorine-containing erythro isomer, 5, was inactive, the threo isomers, 2'-F-dd-ara-A (3) and 2'-F-dd-ara-I (4), were just as potent and active in protecting CD4+ ATH8 cells from the cytopathogenic effects of HIV-1 as the parent drugs. Exposure to pH 1 at 37 degrees C prior to testing destroyed the activity of ddA and ddI but left the anti-HIV properties of 3 and 4 unchanged. The fluorinated analogues also protected cells exposed to HIV-2 and inhibited gag gene product expression but not as effectively as the parent compounds. The fluorine-containing analogues appear to be somewhat more toxic in vitro to the antigen- and mitogen-driven proliferation of immunocompetent cells than their corresponding parent compounds.

  Stereoselective pyramidalization of free radicals by a vicinal fluorine substituent, the beta-fluorine effect, was invoked to rationalize a 77:23 anti/syn ratio of 2-deuterio-1-fluorocyclopentanes obtained by radical reduction of trans-2-fluoro-1-bromocyclopentane with tributyltin deuteride (Dolbier, W. R., Jr.; Bartberger, M. D. J. Org. Chem. 1995, 60, 4984-4985). We have evaluated analogous reductions

  借助邻位氟取代基对自由基进行立体选择性锥体化，即β-氟效应，以合理化通过反式-2-氟-1-基的自由基还原而获得的2-氘-1-氟环戊烷的77:23反/同比例。溴环戊烷和氘化三丁基锡（Dolbier，WR，Jr .; Bartberger，MDJ Org.Chem。1995，60，4984-4985）。我们已经评估了某些腺嘌呤2'（3'）-氟-3'（2'）-O-苯氧基硫羰基核苷衍生物的四种可能的立体异构体的类似还原。在所有情况下，腺嘌呤在β面上的立体作用都将氘从锡烷转移到呋喃糖环的α面上的C2'（C3'）。然而，β-氟效应增加了氘转移与邻位氟取代基的比率。
