Biological Activity

Onalespib lactate is a potent and cross the blood-brain barrier heat-shock-protein-90 (Hsp90) inhibitor with an Kd value of 0.71 nM. Onalespib lactate inhibits the proliferation, survival and migration. Onalespib lactate decreases the expression of EGFR, p-EGFR, AKT, P-AKT, ERK1/2, P-ERK1/2, S6, P-S6 protein. Onalespib lactate shows antitumor activity. Onalespib lactate has the potential for the research of non-small cell lung cancer (NSCLC).

Conversion of different model animals based on BSA (PMID: 27057123)
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.
