Praeruptorin C (Pra-C), one of the principal bioactive components derived from the root of Peucedanum praeruptorum Dunn, has been widely used as an antioxidant and a calcium antagonist to treat diseases, Pra-C partially also protects cortical neurons by inhibiting the expression of GluN2B-containing NMDA receptors and regulating the Bcl-2 family.[1]
Praeruptorin C can completely inhibit SMC proliferation induced by Ang II and partly inhibit the growth of SMC- induced by bovine serum, which is important in prevention and treatment of vascular hyperplastic disease.[2]
Praeruptorin C can attenuate the level of NCX mRNA , has cardioprotective effect on NCX mediates during ischemia/reperfusion in the neonatal rat cardiomyocytes I/R model; cardioprotection induced by hypoxia preconditioning and praeruptorin C preconditioning against hypoxia-reoxygenation injury may be related with upregulating phospholamban phosphorylation.[3,4]
