Biological Activity

CCT241533 hydrochloride is a potent serine/threonine checkpoint kinase (Chk2) inhibitor with IC50 of 3 nM. CCT241533 hydrochloride shows minimal cross-reactivity against a panel of kinases at 1 uM. CCT241533 HCl blocked CHK2 activity in human tumor cell lines in response to DNA damage, as shown by inhibition of CHK2 autophosphorylation at S516, band shift mobility changes, and HDMX degradation. CCT241533 did not potentiate the cytotoxicity of a selection of genotoxic agents in several cell lines. CCT241533 HCl abolished the induction of the pS516 CHK2 signal, implying that the potentiation of PARP inhibitor cell killing by CCT241533 was due to inhibition of CHK2.

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.
