HBDDE, a derivative of Ellagic acid, is an isoform-selective PKCα and PKCγ inhibitor with IC50s of 43 μM and 50 μM, respectively. HBDDE shows selective for PKCα/PKCγ over PKCδ, PKCβI and PKCβII isozymes. HBDDE induces neuronal apoptosis[1][2].

Target	PKCα:43 μM (IC50) PKCγ:50 μM (IC50)
In Vitro	HBDDE (50 μM; 5 hours) treatment reduces cell viability significantly by ~70%. HBDDE exhibits a marked increase in caspase-3 activity[1]. Cell Viability Assay[1] Cell Line: Cerebellar granule cells Concentration: 50 μM Incubation Time: 5 hours Result: Reduced cell viability significantly by ~70%.
