产品介绍
INO-1001 (PARP-IN-1) 是一种有效的 PARP 抑制剂,在 CHO 细胞中的 IC50 约为 50 nM,并在再灌注过程中充当氧化剂诱导的肌细胞功能障碍的介质。

Kinase experiment:

PARP activity is measured with a PARP Activity Assay Kit. This method measures relative PARP activity by determining the level of incorporation of 3H-NAD into trichloroacetic acid (TCA) precipitable material in the presence of sheared genomic DNA, which activates PARP. The reaction mixture is added directly to washed cultures in 12-well culture plates and the reaction is allowed to proceed for 60 minutes at 37℃ before the cells are removed mechanically, transferred to a microcentrifuge tube, and precipitated with ice-cold 5% TCA.

Animal experiment:

Male db/db (Leprdb/db) mice, together with nondiabetic control db/m mice on C57BLKs/J background, are used. INO-1001 and PJ-34 treatment are initiated at 5 weeks of age. In sterile water that is sweetened with NutraSweet, 4.8 g/L 3-Aminobenzamide and 2.4 g/L PJ-34 is dissolved. Control animals receive sweetened water only. The average inhibitor consumption is 60 mg/kg 3-Aminobenzamide and 30 mg/kg PJ-34.

产品描述

INO-1001 is a potent and selective inhibitor of PARP [1].

Poly(ADP-ribose) polymerase (PARP) is an enzyme involved in DNA repair and as a mediator of energy failure-induced cell death and NAD+ depletion [1].

In rodent and human fibroblast cell lines, INO-1001 significantly inhibited PARP activity. Treatment of 10 μM INO-1001 and a single dose of radiation caused significant radiosensitization of the three cells lines. While apoptosis was not increased, suggesting that INO-1001 increased radiation-induced cell killing through interfering with DNA repair mechanisms, increasing necrotic cell death [2].

In adult male mice subjected to moderate controlled cortical impact (CCI), injection intracerebral with INO-1001 (1.6 mg/kg) preserved brain NAD+ levels. In the Morris water maze, INO-1001 reduced the latency time to find the hidden platform and increased the time in the target quadrant [1]. In dogs underwent hypothermic cardiopulmonary bypass, reperfusion for 60 min after treatment with INO-1001 (1 mg/kg), INO-1001 significantly recovered left and right ventricular systolic function, increased coronary blood flow [3].
