  • Patent number: 6034096
    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.
