Biological Activity

Cyasterone, a natural EGFR inhibitor, was primarily isolated from Ajuga Decumbens Thunb (Labiatae). Cyasterone showed antiproliferative effects by inducing apoptosis and cell cycle arrest. Cyasterone could be used in studies against human tumors.

Chemical Information
Molecular Weight 520.65
Formula C29H44O8
CAS Number 17086-76-9
Form Solid
Solubility (25°C) DMSO ≥ 60 mg/mL
Storage 4°C, protect from light, dry, sealed
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
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.
