Biological Activity

NVP-TNKS656(TNKS-656) is a highly potent, selective, and orally active TNKS2 inhibitor with IC50 of 6 nM; >300 fold selectivity against PARP1 and PARP2. NVP-TNKS656 was identified as an orally active antagonist of Wnt pathway activity in the MMTV-Wnt1 mouse xenograft model. With an enthalpy-driven thermodynamic signature of binding, highly favorable physicochemical properties, and high lipophilic efficiency, NVP-TNKS656 is well suited for further in vivo validation studies.

Method Apoptosis assays
Cell Lines colorectal cancer cell lines
Concentrations 100 nmol/L
Incubation Time 48 hours
Results The repression of the Wnt/b-catenin pathway by NVP-TNKS656 alone did not promote apoptosis in DLD1 or HT29 colon cancer cells but enhanced the apoptosis induced by exogenous nuclear FOXO3A-ER

Formulation 4% HCl:10% propylene glycol:20% Solutol HS15:60.5% D5W:0.5% NaOH
Dosages 350 mg/kg

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.
