Synthetic bolaamphiphilic analogs of galactosylceramide (GalCer) potentially binding to the V3 domain of HIV-1 gp 120: key role of their hydrophobicity

Abstract

New routes in three or four steps to synthetic bolaamphiphilic analogs of galactosylceramide (GalCer) are presented in this work, using unprotected lactose as the starting sugar. Some of these new anionic compounds obtained in good yields bind to the V3 domain of HIV-1 gp 120 and thus are the base of potential low-cost anti HIV-1 drugs. Moreover, structure-activity relationships show that the hydrophobic moiety of the molecule plays a key role in this activity. Synthèse de bolaamphiphiles analogues du galactosylceramide (GalCer) pouvant interagir avec la boucle V3 de la gp 120 du VIH-1: rôle cle′ de leur hydrophobie. De nouveaux compose′s bolaformes analogues du galactosylce′ramide (GalCer) sont pre′sente′s dans ce travail. Leur synthèse en trois ou quatre e′tapes met en jeu le lactose non-prote′ge′ comme sucre de de′part. Certains de ces nouveaux compose′s se lient à la boucle V3 de la gp 120 du VIH-1 et constituent donc une base pour obtenir de nouveaux agents anti VIH à faible coût. En outre, les relations structure-activite′ montrent que la partie hydrophobe de la mole′cule joue un rôle cle′ dans cette activite′.
