Biological Activity

Sis a selective melatoninergic ligand that functions as an antagonist of the MT1 receptor and MT2 receptor. By blocking melatonin receptor-mediated G-protein activation, S26131 inhibits melatonin-dependent signaling pathways. Consequently, this subtype-selective antagonism enables the precise dissection of MT1-specific downstream functions and cellular responses in melatoninergic research. [1]
