Biological Activity

PSB 36 is a potent and selective A1 adenosine receptor antagonist. Displays binding affinities of 0.12, 187, 552, 6500 and 2300 nM for rA1, hA2B, rA2A, rA3 and hA3 receptors respectively. Demonstrates greater selectivity than DPCPX.

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 Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.
