title: Synthesis and immunotropic properties of 5-substituted 1,5-benzodiazepin-2-ones derivatives in cultures of human peripheral blood cells, Part III.
abstract: The reaction of 4-methyl-(A) and 3-methyl-1H-2,3,4,5-tetrahydro-1,5-benzodiazepin-2-one (B) with selected alpha,beta-unsaturated acid chlorides: crotonoyl, cinnamoyl, and 4-nitrocinnamoyl is described. We have also characterized immunotropic activities of these compounds in the proliferative response of human lymphocytes to phytohemagglutinin A (PHA) or to allogeneic cells in one-way mixed lymphocyte reaction (MLR), as well as their action on tumor necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6) production in peripheral blood mononuclear cells (PBMC) and mixed lymphocyte cultures (MLC). Some of the compounds exhibited regulatory activities in the proliferative response of cells to PHA depending on the reactivity of cells to PHA. The MLR induced proliferation of lymphocytes was moderately inhibited by two selected compounds. The compounds showed also inhibitor properties with regard to lipopolysaccharide (LPS)- and MLR-induced TNF-alpha production. Structure-activity relationship was discussed.
