Hazard Information | Back Directory | [Uses]
Riviciclib (P276-00 free base) is a potent cyclin-dependent kinase (CDK) inhibitor, which inhibits CDK9-cyclinT1, CDK4-cyclin D1, and CDK1-cyclinB with IC50s of 20 nM, 63 nM, and 79 nM, respectively[1][2].
Riviciclib shows antitumor activity on cisplatin-resistant cells[3]. | [in vivo]
Riviciclib (administered i.p.; 35 kg/mg daily for 10 days, in human xenograft mode with severe combined immunodeficient mice) shows significant inhibition in the growth of human colon carcinoma HCT-116 xenograft[3].
Riviciclib (administered via i.p.; 50 mg/kg once daily; 30 mg/kg twice daily for 18 treatments, in human xenograft mode with severe combined immunodeficient mice) significantly inhibits growth[3]. Animal Model: | Human xenograft mode with HCT-116 tumor model (severe combined immunodeficient mice)[3] | Dosage: | 35 mg/kg | Administration: | Administered i.p.; daily for 10 days | Result: | Given 35 mg/kg showed significant inhibition in the growth. |
Animal Model: | Human xenograft model with H-460 tumor xenograft (severe combined immunodeficient mice)[3] | Dosage: | 50 mg/kg; 30 mg/kg | Administration: | Administered i.p.; 50 mg/kg once daily for 20 days; Administered i.p.; 30 mg/kg twice daily for 18 treatments | Result: | Given 50 mg/kg and 30 mg/kg twice daily significantly inhibited growth. |
