描述 | Poly(ADP-ribose) polymerase-1 (PARP1) and poly(ADP-ribose) polymerase-2 (PARP2), members of the PARP superfamily of enzymes, play a key role in DNA damage response (DDR) by acting as DNA damage sensors and signal transducers. In a process known as poly-ADP-ribosylation (PARylation), PARP1 transfers ADP-ribose from nicotinamide adenine dinucleotide (NAD+) to target proteins, which in turn enables recruitment of DNA repair proteins[3]. BGP-15, a hydroxylamine derivative, is a pharmacological coinducer of Hsp72 (heat shock protein 72), shown safe and well tolerated in phase 2 clinical trials for diabetes and insulin resistance[4]. BGP-15 is also a inhibitor of PARP. BGP-15 either blocked or significantly reduced (60-90% in 100-200 mg/kg oral dose) cisplatin induced increase in serum urea and creatinine level in mice and rats and prevented the structural degeneration of the kidney, as well. The nephroprotective effect of BGP-15 treatment was revealed also in living mice by MRI analysis manifesting in the lack of oedema which otherwise developed as a result of cisplatin treatment. BGP-15 decreased cisplatin-induced ROS production in rat kidney mitochondria and improved the antioxidant status of the kidney in mice with cisplatin-induced nephropathy. In rat kidney, cisplatin caused a decrease in the level of Bcl-x, a mitochondrial protective protein, and this was normalized by BGP-15 treatment. Moreover, treatment with BGP-15 increased the mean survival time of cisplatin-treated P-388 leukemia bearing mice from 13 to 19 days[2]. |
