AG14361 is a potent oly(ADP-ribose) polymerase-1 inhibitor (human PARP-1 Ki = 5.8 nM) that suppresses 25 μM MNNG-induced PARP-1 activity (NAD+ depletion = 70% without vs.12% with 0.4 μM AG14361; 87% reduced ADP-ribose polymer induction with 0.4 μM AG14361) and greatly amplifies temozolomide and topotecan cytotoxicity (2.2- and 2.0-fold lower IG50, respectively, with 0.4 μM AG14361) in A549 cultures. AG14361 is shown to selectively kill BRCA2-deficient cells over BRCA2-expressing cells both in cultures (1-10 μM) and in mice in vivo (25 mg/10 mL/kg/d ip).
Potent poly(ADP-ribose) polymerase-1 (PARP-1) inhibitor in vitro and in vivo.

Novel tricyclic benzimidazole carboxamide poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors have been synthesized. Several compounds were found to be powerful chemopotentiators of temozolomide and topotecan in both A549 and LoVo cell lines. In vitro inhibition of PARP-1 was confirmed by direct measurement
The activation and recruitment of NK cells to the site of viral infection are crucial for virus control. However, it remains largely unknown what controls the recruitment of the activated NK cells to the infection site. In a model of
Poly(ADP-ribose) polymerase (PARP1) facilitates DNA repair by binding to DNA breaks and attracting DNA repair proteins to the site of damage. Nevertheless, PARP1-/- mice are viable, fertile and do not develop early onset tumours. Here, we show that PARP inhibitors

Parp inhibitors (Parpi) are commonly used as single agents for the management of tumors with homologous recombination repair (HRR) deficiencies, but combination with radiotherapy (RT) is not widely considered due to the modest radiosensitization typically observed. BMN673 is one of
Poly(ADP-ribose)polymerases (PARPs) are a family of NAD+ consuming enzymes that play a crucial role in many cellular processes, most clearly in maintaining genome integrity. Here, we present an extensive analysis of the alteration of mitochondrial morphology and the relationship to
