Novel Drp1 GTPase Inhibitor, Drpitor1a: Efficacy in Pulmonary Hypertension

Abstract

Drpitor1a is a specific Drp1 GTPase inhibitor that reduces mitochondrial fission in PAH hPASMC and PAH BOEC. Drpitor1a reduces proliferation and induces apoptosis in PAH hPASMC and regresses monocrotaline-PAH. Drp1 is a therapeutic target in PAH, and Drpitor1a is a potential therapy with an interesting therapeutic sexual dimorphism.
