1,4-Diamino-2,3-dicyano-1,4-bis(phenylthio)butadiene

1,4-diamino-2,3-dicyano-1,4-bis(phenylthio)butadiene is a dinitrile that is succinonitrile in which the methylene hydrogens at positions 2 and 3 are substituted by amino(phenylsulfanyl)methylidene groups. It acts as an inhibitor of MEK (mitogen activated protein kinase kinase). It has a role as a protein kinase inhibitor. It is an aryl sulfide, an enamine and a dinitrile. It derives from a hydride of a buta-1,3-diene.
