A purine base found in most body tissues and fluids, certain plants, and some urinary calculi. It is an intermediate in the degradation of adenosine monophosphate to uric acid, being formed by oxidation of hypoxanthine. The methylated xanthine compounds caffeine, theobromine, and theophylline and their derivatives are used in medicine for their bronchodilator effects. (Dorland, 28th ed)
Conversion of different model animals based on BSA(Value based on data from FDA Draft Guidelines)
Animal A (mg/kg)=Animal B(mg/kg)multiplied by AnimalBm系数/AnimalAm系数 For example, to modify the dose of resveratrol uesd for a mouse(22.4mg/kg) to a dose based on the BSA for a rat, multiply 22.4mg/kg by the Km factor for a mouse and zhen divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2mg/kg
