E7016 (GPI 21016) 是一种口服有效的PARP抑制剂。E7016 可以通过抑制 DNA 修复来增强肿瘤细胞在体内外的放射敏感性。E7016 用作一种潜在的抗肿瘤剂。
生物活性 | E7016 (GPI 21016) is an orally availablePARPinhibitor. E7016 can enhance tumor cell radiosensitivity in vitro and in vivo through the inhibition of DNA repair. E7016 acts as a potential anticancer agent[1][2]. |
IC50& Target[1] | |
体外研究 (In Vitro) | E7016 can enhance tumor cell radiosensitivity through the inhibition of DNA repair[1]. E7016 (3 μM)-mediated radiosensitization occurs through an increase in the number of cells undergoing mitotic catastrophe and not an increase in the number of cells undergoing apoptosis[1]. E7016 inhibits PARP by mimicking NAD+[2].
Apoptosis Analysis[1] Cell Line: | The U251 human glioblastoma cell line | Concentration: | 3 μM | Incubation Time: | 6 hours prior to irradiation and were stained at 24 and 72 h postirradiation | Result: | The number of cells in mitotic catastrophe was significantly greater in the E7016-treated irradiated cells than in cells that received radiation only at 24 hours postirradiation. |

体内研究 (In Vivo) | E7016 has antitumor efficacy in murine xenograft studies[1]. Administration of E7016 (40 mg/kg; oral gavage) to mice bearing U251 xenografts enhances the effectiveness of the Temozolomide/radiation combination[1]. Mice treated with E7016/irradiation/Temozolomide have an additional growth delay of six days compared with the combination of Temozolomide and irradiation in vivo[1].
Animal Model: | Four- to six-week-old female nude mice[3] | Dosage: | 40 mg/kg | Administration: | Oral gavage | Result: | E7016 enhanced the radiation/Temozolomide (3 mg/kg orally)-induced tumor growth delay of U251 xenografts. |
