生物活性
Troxacitabine是一種具有強(qiáng)效抗腫瘤活性的二氧戊環(huán)類似物。
體外研究

Troxacitabine has shown cutotoxicity in cancer cell lines of hepatocellular (HepG2), prostate (PC3, DUI45), non-small cell lung (NCI-H460, NCr-322M) colon (HT29), renal (CAK-l, A498, RXF-393, SNI2-C) and pancreatic origin (Pnac-Ol, MiaPa Ca) with IC 50 s range from 15-35 μM.

體內(nèi)研究

Troxacitabine is highly active against the Panc-01 model, with TGI levels of 88.5% and 84.3% at the 10 and 25 mg/kg doses, respectively. The mean final tumor weights for animals given troxacitabine are also significantly smaller compared with vehicle controls. Troxacitabine has less activity against the MiaPaCa model. Troxacitabine is very effective in human RCC tumor xenograft models, including CAM-i, A498, RXF-393, and SN12C carcinomas. Very good responses are ob served in animals bearing CAM-i, A498, and RXF-393 RCC tumors given i.p. doses of 10, 25, and 50 mg/kg twice a day for 5 days.
