Application

SRPIN340 has been used as a serine-arginine protein kinase (SRPK) inhibitor to identify if SRPK can phosphorylate the E3 ubiquitin ligase RNF12 ser/arg (SR)-motifs in vivo.

Biochem/physiol Actions

SRPIN340 is a cell-permeable, specific and potent inhibitor of Serine-Arginine-Rich Protein Kinase (SRPK) that down-regulates SRp75 and inhibits expression of Sindbis, hepatitis C virus (HCV), HIV, and cytomegalovirus viruses. SRPIN340 appears to be most effective for inhibiting acutely replicating viruses. SRPIN340 suppresses Vegf expression and attenuated choroidal neovascularization (CNV) formation in mice model.
SRPIN340 is an isonicotinamide compound. It protects cardiomyocytes against hydrogen peroxide (H2O2) induced oxidative damage by serine-arginine protein kinase 1/2 (SRPK1/2) inhibition-mediated protein kinase B (AKT) activation.

To investigate the applicability of serine/arginine-rich protein kinase (SRPK)-specific inhibitor, SRPIN340, for attenuation of choroidal neovascularization (CNV) formation using a mouse model. Laser photocoagulation was performed to induce CNV in C57BL/6J mice, followed by intravitreal injection of SRPIN340 or vehicle.
