A. Benjahad et al., SYNTHESIS AND ANTIRETROVIRAL EVALUATION OF 3-ALKYL 2-PIPERAZINONE NUCLEOSIDE ANALOGS, Tetrahedron letters, 35(51), 1994, pp. 9545-9548
Glycosylation of 3-alkyl N-4-(3-hydroxypropyl) 2-piperazinones by prot
ected 1-O-acetyl ribofuranoses produces nucleoside analogs in which th
e base is separated from the sugar by a hydrocarbon spacer arm. The pr
eliminary in vitro test results against retroviruses seem promising fo
r compounds bearing a long alkyl chain.
