Biological Activity

Bafilomycin A1 is a toxic macrolide antibiotic derived from Streptomyces griseus. Bafilomycin A1 inhibits the short circuit current induced by the outer mantle epithelium (OME). The IC50 and maximum inhibition dose of Bafilomycin A1 are 0.17 μM and 0.5 μM, respectively. Bafilomycins are specific inhibitors of vacuolar-type H+-ATPase. (V-ATPase). The most used bafilomycin is bafilomycin A1. This is a useful tool as it can prevent the re-acidification of synaptic vesicles once they have undergone exocytosis.

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.
