title: Synthesis, lipophilicity and anti-HIV activity of a new brominated analog of zidovudine.
abstract: A novel cyclic bromine zidovudine analog, (-)-trans-(5S,6S)-5-bromo-6,5'- epoxy-5,6-dihydro-3'-azido-3'-deoxythymidine (2), and its diastereoisomer (+)-trans-(5R,6R)-(3) were synthesized and characterized by spectroscopic methods, obtaining 3 in very low yields. The major product 2 presents a selectivity index (CCID50/IC50) similar to zidovudine but 55.5 times with higher lipophilicity, which should increase the ability of 2 to cross the blood-brain barrier by a non facilitated diffusion mechanism.
