Biological Activity

PS48 is a PDK1 (phosphoinositide-dependent protein kinase 1) activator which binds to the HM/PIF binding pocket rather than the ATP-binding site. PS48 is one of only a few truly allosteric compounds targeting a regulatory binding site on a protein kinase catalytic domain that is not adjacent to or overlapping with the ATP-binding site.

Chemical Information

Formula C17H15ClO2
CAS Number 1180676-32-7
Solubility (25°C) DMSO: ≥20 mg/mL
Storage Powder          -20°C   3 years ;  4°C   2 years

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.
