CYP3 Substrate

Praeruptorin A ((+)-Praeruptorin A) is an orally active isomer of (±)-Praeruptorin A (HY-N0081). Praeruptorin A also acts as a Calcium channel blocker. Praeruptorin A can be isolated from Peucedanum. Praeruptorin A serves as a substrate for CYP3A4. Praeruptorin A downregulates NMDA receptors containing GluN2B and inhibits neuronal Apoptosis. Praeruptorin A mediates vasodilation, inhibits vascular hypertrophy and reduces blood pressure. Praeruptorin A can be used in research related to neurological diseases, myocardial ischemia, heart failure, exertional angina, renovascular hypertension and spontaneous hypertension.

Dimethocaine (Larocaine) is a cocaine derivative and ester-type local anesthetic. Dimethocaine is metabolized by hP450 1A2, 2C19, 2D6, and 3A4 in vitro. Dimethocaine exhibits locomotor-promoting, reinforcing, and anxiogenic effects.

HN0037 is a selective, orally active Helicase-primase inhibitor. HN0037 is mainly metabolized by CYP3A4. HN0037 inhibits HSV replication by targeting the viral helicase-primase complex, which consists of three proteins encoded by UL5 (helicase), UL52 (primase), and UL8 (scaffold protein that promotes primer synthesis).
