Rosacelose, a new anti-HIV polysaccharide composed of glucose and fucose sulfate, has been isolated from aqueous extract of the marine sponge Mixylla rosacea. Extensive use of 1 H and 13 C multidimensional NMR spectroscopy, combined with chemical analysis, have allowed to establish a linear polysaccharide structure mainly composed of 4,6-disulfated 3-O-glycosylated α-d-glucopyranosyl...
With the aim at improving the transport of the current HIV protease inhibitors across the intestinal and blood brain barriers and their penetration into the central nervous system, the synthesis of various acyl and carbamatoyl glucose-containing prodrugs derived from saquinavir, indinavir and nelfinavir, their in vitro stability with respect to hydrolysis, and their anti-HIV activity have been investigated...
