Supinoxin Usage And Synthesis
Uses
Supinoxin (RX-5902) is an orally active inhibitor of phosphorylated-p68 RNA helicase (P-p68) and a potent first-in-class anti-cancer agent. Supinoxin interacts with Y593 phosphorylated-p68 and attenuates the nuclear shuttling of β-catenin. Supinoxin induces cell apoptosis and inhibits growth of TNBC cancer cell lines with IC50s ranging from 10 nM to 20 nM[1][2].
in vivo
RX-5902 (oral administration; 160/320/600 mg/kg; once weekly for 3 weeks) significant dose-dependent tumor growth inhibition (TGI) in the MDA-MB-231 model, exhibits TGI of 55.7%, 80.29% and 94.58% at 160 mg/kg, 320 mg/kg and 600 mg/kg, respectively. It is more efficacious than the chemotherapy control arm of nab-paclitaxel (TGI 45%)[1].
| Animal Model: | MDAMD-231 xenograft model in mice[1] |
| Dosage: | 160 mg/kg; 320 mg/kg; 600 mg/kg |
| Administration: | Oral administration; once weekly for 3 weeks |
| Result: | Decreased tumor volume as a dose-dependent manner. |
