PQ401 是一种有效的IGF-IR抑制剂。在 MCF-7 细胞中，PQ401 抑制 IGF-I 刺激的 IGF-IR 自磷酸化，IC50为 12.0 μM。PQ401 可有效抑制 IGF-I 刺激的 MCF-7 细胞生长 (IC50为 6 μM)。PQ401 有潜力用于乳腺癌和其他对 IGF-I 敏感的癌症的研究。PQ401 诱导 caspase 介导的细胞凋亡 (apoptosis)。
| 生物活性 | PQ401 is a potent inhibitor ofIGF-IRsignaling. PQ401 inhibits IGF-I-stimulated IGF-IR autophosphorylation with an IC50of 12.0 μM in a series of studies in MCF-7 cells. PQ401 is effective at inhibiting IGF-I-stimulated growth of MCF-7 cells (IC50, 6 μM). PQ401 is a potential agent for breast and other IGF-I-sensitive cancers. PQ401 induces caspase-mediatedapoptosis[1]. |

体外研究
(In Vitro) | PQ401 (1, 5, 10, 25, and 50 μM; 3 days) inhibits proliferation of cultured MCF-7 cells grown in serum or IGF-I in MCF-7 cells[1].
Twenty-four hours of treatment with 15 μM PQ401 induces caspase-mediated apoptosis[1].
PQ401 inhibits autophosphorylation of the IGF-IR kinase domain at concentrations<100 nm, with an ic50<1 μM.
Cell Proliferation Assay[1] | Cell Line: | Breast cancer cells, MCF-7 cells | | Concentration: | 1, 5, 10, 25, and 50 μM | | Incubation Time: | 3 days | | Result: | Significantly reduced proliferation (IC50, 8 μM) at concentrations in the range of 1 μM.
Produced a dramatic reduction in cell number from pretreatment levels at concentrations >10 μM. |

体内研究
(In Vivo) | PQ401 (50 or 100 mg/kg; i.p.; thrice a week) results in a significant dose-dependent reduction in tumor growth over the course of the study. PQ401 reduces the growth rate of MCNeuA cells implanted into mice[1].
| Animal Model: | Female mice were MCNeuA tumor cells[1] | | Dosage: | 50 or 100 mg/kg | | Administration: | Administered i.p. thrice a week; 24 days | | Result: | Resulted in a significant dose-dependent reduction in tumor growth. Tumor growth in the animals treated with 100 mg/kg was 20% of that in the vehicle-treated controls. This dosing protocol was well tolerated by the animals. |
