UPF 1069 is a selective PARP2 inhibitor with IC50 of 0.3 μM. UPF 1069 inhibits PARP1 with IC50 of 8 μM. In mouse mixed cortical cells exposed to OGD, UPF-1069 (1-10 mM) significantly reduces post-ischaemic damage.
|Animal models||Rats deprived of hippocampi.|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
Selective PARP-2 inhibitors increase apoptosis in hippocampal slices but protect cortical cells in models of post-ischaemic brain damage.
