Abstract: The present invention relates to a process for preparing 5′-acetylstavudine, an intermediate which is useful in the preparation of 2′,3′-didehydro-3′-deoxythymidine, an active principle with antiviral action which is commonly known as stavudine (D4T).

Abstract: The present invention provides medicinal compounds that are characterized by a cyclic moiety (A) linked through a carboxamido group (more specifically, a carbamate group or a urea group) to another cyclic moiety (B) which is in turn linked to another, N-substituted carboxamido group. These compounds can be used an anti-inflammatory and immunosuppressive agents, as demonstrated by their inhibition of the production of IL-1.beta. in vitro and TNF.alpha. in vivo.

Abstract: Analogues of the active metabolite of leflunomide, and to the use thereof as immunosuppressive and/or antinflammatory agents.

Abstract: Diesters of carbonic acid disubstituted with primary, secondary or tertiary amine groups, pharmaceutically acceptable salts thereof, and their use as antiviral and inti-inflammatory agents.
