Mechanism of Action

Targets/IC₅₀/Ki	PKCβ1 (Cell-free assay) 4.7 nM PKCβ2 (Cell-free assay) 5.9 nM PKCη (Cell-free assay) 0.052 μM PKCδ (Cell-free assay) 0.25 μM PKCγ (Cell-free assay) 0.3 μM PKCα (Cell-free assay) 0.36 μM
In vitro	LY333531 strikingly decreases the chance of HUVEC survival and the effect of LY333531 on apoptotic cell death in HUVEC significantly increases compared with the AGEs group. Blockade of PKC-beta up-regulates the expression of Bax and Bad proteins and down-regulates the expression of Bcl-2 protein. Moreover, LY333531 reduces the ratio of Bcl-2/Bax. LY333531 can further prompt AGEs-induced endothelial cells apoptosis. The increased expression of Bax, Bad and decreased expression of Bcl-2 and Bcl-2/Bax ratio are associated with the apoptotic process.
In vivo	LY333531 treatment (for a duration of 4 weeks) prevents excessive PKCb2 activation and attenuates cardiac diastolic dysfunction in rats with streptozotocin-induced diabetes. LY333531 suppresses the decreased expression of myocardial NO, Cav-3, phosphorylated (p)-Akt, and p-eNOS and also mitigates the augmentation of O2-, nitrotyrosine, Cav-1, and iNOS expression.
