Biological Activity

MK-3207 hydrochloride is a potent and orally bioavailable calcitonin gene-related peptide (CGRP) receptor antagonist. MK-3207 potently inhibits human α-CGRP-induced cAMP production in HEK293 cells stably expressing human CLR/RAMP1 with an IC50 of 0.12 nM, and maintains similar potency in the presence of 50% human serum with an IC50 of 0.17 nM, indicating that the activity of MK-3207 would not be dramatically affected by plasma protein binding in vivo. MK-3207 displays lower affinity for CGRP receptors from other species, including canine and rodent. MK-3207 produced a concentration-dependent inhibition of dermal vasodilation, with plasma concentrations of 0.8 and 7 nM required to block 50 and 90% of the blood flow increase, respectively. In vitro, MK-3207 is a potent antagonist of the human and rhesus monkey CGRP receptors (K(i) = 0.024 nM).

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.
