Description
Enzastaurin (170364-57-5) is a potent and selective PKCβ inhibitor.? IC50 = 6, 39, 83 and 110 nM, for PKCβ, PKCα, PKCγ and PKCε respectively.1 Induces apoptosis in multiple myeloma cell lines via inhibition of the AKT signaling pathway.2 Induces mitotic missegregation and preferential cytotoxicity in colorectal cancer cells with chromosomal instability.3 Attenuates amphetamine-stimulated dopamine efflux.4 Inhibits blood-brain barrier leakiness in a mouse model.5
Uses
PKCβ-selective inhibitor, suppresses angiogenesis.
Uses
Enzastaurin has been used in splicing analysis to study its effects on splicing of a mutated exon.
Definition
ChEBI: 3-(1-methyl-3-indolyl)-4-[1-[1-(2-pyridinylmethyl)-4-piperidinyl]-3-indolyl]pyrrole-2,5-dione is a member of indoles and a member of maleimides.
Biochem/physiol Actions
Enzastaurin is a potent and PKCβ preferring inhibitor. Also, Enzastaurin inhibits AKT and GSK3β. Enzastaurin acts as anti-angiogenic and antineoplastic agent.
