Biological Activity

Cryptotanshinone was originally isolated from the dried roots of Salvia militorrhiza, an herb that is used extensively in Asian medicine and that is known to exert beneficial effects on the circulatory system.Cryptotanshinone rapidly inhibited STAT3 Tyr705 phosphorylation in DU145 prostate cancer cells and the growth of the cells through 96 hours of the treatment.Cryptotanshinone significantly attenuated atherosclerotic plaque formation and enhanced plaque stability in ApoE-/- mice by inhibiting lectin-like oxLDL receptor-1 (LOX-1) and matrix metalloproteinase-9 (MMP-9) expression, as well as inhibiting reactive oxygen species (ROS) generation and nuclear factor- kappa B (NF-κB) activation.In vitro,Cryptotanshinone decreased oxLDL-induced LOX-1 mRNA and protein expression, and thereby, inhibited LOX-1-mediated monocytes adhesion to HUVECs through reducing the expression of adhesion molecules (ICAM-1 and VCAM-1).Cryptotanshinone inhibited NADPH oxidase subunit 4 (NOX4)-mediated ROS generation and consequent activation of NF-κB in HUVECs.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
