Biological Activity

(S)-Bay K 8644 (100 nM) increased whole-cell Ca2+ currents in A7r5 smooth muscle cells but effectively blocked further stimulation by 1 microM FPL 64176.(-)-S-Bay K 8644 enhanced transcoronary exchange more markedly than (+/-)-Bay W 5035 or (+/-)-Bay T 5006, reflecting the differences in coronary constrictor activity.

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.
