[2-fluoro-2',5'-dimethyl-4'-[6-(3-methyl-2-butenyloxy)pyridin-3-yl]biphenyl-4-yl]-(3-methyl-2-butenyl)amine i.e. S-2678, suppresses immunoglobulin production in human peripheral blood mononuclear cells in vitro, with little or no inhibition of cell proliferation Homo sapiens
[2-fluoro-2',5'-dimethyl-4'-[6-(3-methyl-2-butenyloxy)pyridin-3-yl]biphenyl-4-yl]-(3-methyl-2-butenyl)amine i.e. S-2678, suppresses immunoglobulin production in mouse B cells in vitro, with little or no inhibition of cell proliferation, probably through inhibition of class switch recombination in the immunoglobulin heavy chain loci in B cells. In vivo antibody production induced by systemic immunization with ovalbumin is dramatically suppressed by oral administration of S-2678, without any toxicological signs. S-2678 does not affect T-cell activation in vitro, and cytokine production induced by intravenous anti-CD3 antibody in mice. S-2678 does not affect host defense in a mouse model of Candida infection, whereas leflunomide severely impaires it Mus musculus
