Ro 90-7501 is an amyloid β42 (Aβ42) protofibrillar and TPR-dependent PP5 inhibitor, a novel radiosensitizer for cervical cancer cells, which inhibits ATM phosphorylation, promotes apoptosis, and induces cell-cycle arrest. Ro 90-7501 also exhibits antiviral activity and potential anticancer activity by inhibiting ATM phosphorylation and DNA repair, and by inhibiting HCMV.

| Description | Ro 90-7501 is an amyloid β42 (Aβ42) protofibrillar and TPR-dependent PP5 inhibitor, a novel radiosensitizer for cervical cancer cells, which inhibits ATM phosphorylation, promotes apoptosis, and induces cell-cycle arrest. Ro 90-7501 also exhibits antiviral activity and potential anticancer activity by inhibiting ATM phosphorylation and DNA repair, and by inhibiting HCMV. |
| In vitro | Compared to control HeLa and ME-180 cells, Ro 90-7501 significantly enhances radiation sensitivity. Following irradiation, Ro 90-7501 markedly increases apoptosis and impairs the cell cycle. Post-irradiation, Ro 90-7501 suppresses the phosphorylation of ATM and its downstream proteins, such as H2AX, Chk1, and Chk2[2]. RO 90-7501 itself does not affect IFN-β and NFκB promoter activity but significantly enhances poly I:C-induced IFN-β promoter activation and dose-dependently inhibits NF-κB activation. Treatment with RO 90-7501 significantly enhances the antiviral activity of poly I:C[1]. |
| In vivo | Treatment with Ro 90-7501 (5 μg/g; intraperitoneal injection; daily; continuous for 21 days; female BALB/c nude mice) significantly delays tumor growth and markedly reduces tumor volume[2]. |
