Abstract: The invention relates to a compound having general formula (I): wherein n is equal to 3; R1 is an ethyl or isopropyl group; each of the R2 groups is independently of each other a hydrogen atom, a C1-C3 alkyl group or a halogen atom; one of the R3 and R4 groups represents a hydrogen atom while the other of the R3 and R4 groups represents an OH or OR5 group, where R5 can be a C2-C7 acyl group, an alkyl(C1-C6)animo-carbonyl group, an aralkyl(C1-C6)aminocarbonyl optionally substituted on the aryl, an arylcarbonyl group optionally substituted or a heteroarylaminocarbonyl group. Said compound is particularly suitable as an antiviral agent and especially as an anti-HIV-1 agent.

Abstract: The invention relates to processes for the preparation of novel aryl-hexafuranosides of the formula ##STR1## in which R.sub.1 is lower alkyl or cycloalkyl and R.sub.2 is hydrogen, lower alkyl or acyl, or R.sub.1 and R.sub.2 together are alkylidene or cycloalkylidene, R.sub.3 is hydrogen, lower alkyl, lower alkenyl or aryl-lower alkyl, R.sub.5a and R.sub.6a independently of one another are hydrogen or lower alkyl, R.sub.5b and R.sub.6b independently of one another are hydrogen, hydroxyl, lower alkoxy or amino, or R.sub.5b and R.sub.6b together are a C--C bond, epoxy or lower alkylidene, and R.sub.6c is aryl, by methods known per se.These novel compounds have an anti-inflammatory and/or antinociceptive action.
