A randomized, placebo-controlled trial to evaluate the tolerability, safety, pharmacokinetics, and pharmacodynamics of a potent inhibitor of poly(ADP-ribose) polymerase (INO-1001) in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention: results of the TIMI 37 trial. Morrow DA, et al. J Thromb Thrombolysis. 2009 May;27(4):359-64. PMID: 18535785.

化学数据 分子量 分子式 CAS号 储存条件
136.15 C7H8N2O 3544-24-9 3年 -20°C 粉末状
溶解性(25°C)
DMSO 27 mg/mL Water <1 mg/mL Ethanol 27 mg/mL
生物活性
INO-1001是一种有效的PARP抑制剂,作用于CHO细胞的IC50为<50 nM,在再灌注期间,是一种因氧化诱导而发生的心肌功能障碍的调节剂。用浓度为0.05 到50 μM的INO-1001处理CHO细胞30分钟,明显抑制PARP 活性, IC50 为50 nM, INO-1001浓度为1 μM 或更高时抑制PARP活性达95%,且没有细胞毒性。此外, INO1001通过阻断大部分受辐射的DNA片段修复而使CHO 细胞敏感。用400 μM H2O2处理后,通过增强乙酰胆碱诱导的, 依赖内皮细胞层的, NO调节的血管舒张,而提 高INO-1001抑制PARP活性。
例如,依据体表面积折算法,将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量,需要将22.4 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数
(6),得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。

方法 浓度
Apoptosis detection. Apoptotic nuclei of cultured podocytes were detected on paraformaldehyde-fixed cells using DAPI (4′,6-diamidino2-phenylindole) staining (1 μg/ml) for 10 min. Cells were analyzed under a fluorescence microscope and assessed for chromatin condensation and segregation. Caspase-3 activity was measured in podocyte extracts using EnzCheck Caspase-3 Assay kit (Molecular Probes) following the manufacturer’s protocol. Nuclear extracts were prepared using Transfactor DB Nuclear extraction kit (Clontech BD Bioscience) following the manufacturer’s protocol. Western blotting was performed using NFκB p50 (Santa Cruz Biotechnology) antibody. NFκB p50 nuclear binding assay was performed using TransFactor Colorimetric kit (Clontech BD) according to the manufacturer’s protocol.
