Velaparib is not overly potent in vivo as a a single agent but potentiates both chemo- and radiotherapy. Like other PARP inhibitors, veliparib is a potent inhibitor of PARP1 and 2 but not the other...

Veliparib is a potent dual PARP1/2 inhibitor. It is highly recommended for studying the function of these targets in vitro. Veliparib has also shown utility in in vivo studies and even some degree of...
Veliparib is a PARP1/2 inhibitor with selectivity sufficient for cellular work to interrogate PARP1/2. While target engagement has been shown in vivo at modest doses, the lack of receptor profiling...
