Ro 90-7501

产品介绍

Ro 90-7501 是一种淀粉样 β₄₂ (Aβ₄₂) 原纤维组装抑制剂，可降低 Aβ₄₂ 诱导的细胞毒性 (EC₅₀ 为 2 μM)。Ro 90-7501 抑制 ATM 磷酸化和 DNA 修复。RO 90-7501选择性增强 TLR3和 RLR 配体诱导的 IFN-β 基因表达和抗病毒反应。Ro 90-7501 还以 TPR 依赖性方式抑制蛋白磷酸酶 5 (PP5)，并对宫颈癌细胞具有显着的放射增敏作用。

生物活性

Ro 90-7501 is an amyloid β₄₂ (Aβ₄₂) fibril assembly inhibitor that reduces Aβ₄₂-induced cytotoxicity (EC₅₀ of 2 μM). Ro 90-7501 inhibits ATM phosphorylation and DNA repair. RO 90-7501 selectively enhances toll-like receptor 3 (TLR3) and RIG-I-like receptor (RLR) ligand-induced IFN-β gene expression and antiviral response. Ro 90-7501 also inhibits protein phosphatase 5 (PP5) in a TPR-dependent manner. Ro 90-7501 has significant radiosensitizing effects on cervical cancer cells^[4].

体外研究

Ro 90-7501 significantly enhances radiosensitivity compared with control HeLa and ME-180 cells. Ro 90-7501 significantly increases apoptosis and impaired cell cycle after irradiation. Ro 90-7501 suppresses the phosphorylation of ATM and its downstream proteins, such as H2AX, Chk1, and Chk2, after irradiation.
RO 90-7501, itself affects neither IFN-β nor NFκB promoter activity, but significantly enhances poly I:C-induced IFN-β promoter activation and inhibits the activation of NFκB in a dose-dependent manner. Treatment of cells with RO 90-7501 significantly enhances the antiviral activity of poly I:C.

体内研究

Ro 90-7501 (5 μg/g; intraperitoneal injection; daily; for 21 days; female BALB/c nude mice) treatment significantly delays tumor growth and significantly decreases tumor volume.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Female BALB/c nude mice (8-week-old) with HeLa cells under irradiation
Dosage:	5 μg/g
Administration:	Intraperitoneal injection; daily; for 21 days
Result:	Tumor growth was significantly delayed in the combination group. Tumor volume was also significantly decreased in the irradiation group.
