Biological Activity

Camptothecin is a DNA topoisomerase I inhibitor. Camptothecin inhibits topo I by blocking the rejoining step of the cleavage/religation reaction of topo-I, resulting in accumulation of a covalent reaction intermediate, the cleavable complex. Camptothecin induces extensive single strand DNA breaks in reactions containing purified mammalian DNA topoisomerase I. DNA breakage in vitro is immediate and reversible. Camptothecin showed remarkable anticancer activity in preliminary clinical trials.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
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 resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
