Biological Activity

Pemetrexed is a high affinity dihydrofolate reductase inhibitor (Ki = 7 nM). Pemetrexed also inhibits thymidylate synthase, AICART and glycinamide ribonucleotide formyltransferase (Ki values are 109 nM, and 3.5 μM and 9.3 μM, respectively). Indirectly activates AMPK. Pemetrexed inhibits proliferation of cancer cell lines in vitro.

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.
