talazoparib

Talazoparib (LT-673) is a new-type PARP inhibitor (IC50: 0.58 nM), It similarly binds to PARP1/2 (Kis: 1.2/0.85 nM).

Talazoparib tosylate is a novel and potent PARP1/2 (n IC50: 0.57 nM for PARP1).

(8R,9S)-Talazoparib is Talazoparib enantiomer , less active than Talazoparib on the inhibition of PARP1 (IC50: 144 nM).

YCH1899, an orally active PARP inhibitor, demonstrates potent inhibition of PARP1/2 with an IC50 of less than 0.001 nM. It shows marked antiproliferative efficacy against Olaparib-resistant (Capan-1/OP) and Talazoparib-resistant (Capan-1/TP) cells with IC50 values of 0.89 nM and 1.13 nM, respectively. Moreover, YCH1899 possesses favorable pharmacokinetic attributes in rats [1].
