BGP-15

BGP-15 is a PARP inhibitor, with an IC₅₀ and a K_i of 120 and 57 μM, respectively. IC50 & Target: IC50: 120 μM (PARP)^[6]
Ki: 57 μM (PARP)^[6] In Vitro: BGP-15 (200 μM) prevents the imatinib mesylate-induced oxidative damages, attenuates the depletion of high-energy phosphates, alters the signaling effect of imatinib mesylate by preventing p38 MAP kinase and JNK activation, and induced the phosphorylation of Akt and GSK-3beta^[5]. In Vivo: BGP-15 (15 mg/kg, p.o.) does not improve skeletal muscle pathology in older mdx mice^[1]. In a rat model, 10 days of BGP-15 treatment greatly improves diaphragm muscle fiber function (by about 100%), although it does not reverse diaphragm atrophy. The treatment also provides protection from myosin PTMs associated with HSP72 induction and PARP-1 inhibition, resulting in improvement of mitochondrial function and content^[2]. BGP-15 (15 mg/kg per day in saline) treatment has no effect in Ntg mice or an independent cohort of normal adult wild-type mice based on morphology, cardiac function and ECG parameters. Treatment with BGP-15 attenuates the increase in atrial size and lung weight. BGP-15 treatment is able to prevent or reduce episodes of arrhythmia. BGP-15 treatment is associated with a reduced PR interval in the HF+AF model^[3]. BGP-15 (10 and 30 mg/kg) increases insulin sensitivity by 50% and 70%, respectively, in cholesterol-fed but not in normal rabbits. After 5 days of treatment with BGP-15, the glucose infusion rate is increased in a dose-dependent manner in genetically insulin-resistant GK rats. The most effective dose is 20 mg/kg, which shows a 71% increase in insulin sensitivity compared to control group^[4].
