Biological Activity

ONO-8590580 is a GABAAα5 negative allosteric modulator which enhances long-term potentiation and improves cognitive deficits in preclinical models. ONO-8590580 (20 mg/kg, p.o.) significantly decreases the number of errors and total latency compared to the control. The present study in which ONO-8590580 but not donepezil significantly decreases the number of errors may suggest that ONO-8590580 could be more potent for the treatment of AD clients.

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 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.
