Patent number: 6541494Abstract: Compounds, preparations and methods for immunosuppressive treatment of autoimmune disorders, graft rejection and/or graft/host disease. Therapeutically effective amounts of certain substituted triarylmethane compounds, such as 1-[(2-chlorophenyl)diphenylmethyl]-1H-pyrazole, are administered to mammalian patients to selectively inhibit the calcium-activated K+ channel (IKCa1) in lymphocytes, monocytes, macrophages, platelets or endothelial cells without concomitant inhibition of P450-dependent enzyme systems, resulting in reduction of antigen-, cytokine-, or mitogen-induced calcium entry through store operated calcium channels in these cells, suppression of cytokine production by these cells, and inhibition of activation of these cells. Such inhibition of the Ca++ activated K+ channel (IKCa1) prevents the pre-Ca++ stage of cell activation and thus causes immunosuppression and an anti-inflammatory response.Type: GrantFiled: January 6, 2000Date of Patent: April 1, 2003Assignee: The Regents of the University of CaliforniaInventors: K. George Chandy, Heike Wulff, Michael D. Cahalan, Stephan Grismer, Heiko J. Rauer, Mark J. Miller
