Biological Activity

Irinotecan hydrochloride trihydrate prevents DNA from unwinding by inhibition of topoisomerase 1. Irinotecan (100 mg/kg) significantly increases amounts of topoisomerase I covalently bound to DNA in stomach, duodenum, colon and liver in male Wistar rats. Irinotecan (20 mg/kg i.p.) induces tumor growth inhibition of 92% in COLO 320 xenograft mice model. Irinotecan is activated by hydrolysis to SN-38. The inhibition of topoisomerase I by the active metabolite SN-38 eventually leads to inhibition of both DNA replication and transcription. Irinotecan is currently in phase 2 clinical trials for the treatment of Non-small Cell Lung Cancer.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)

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

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.
