[CAS NO. 4506-66-5]  Y15

Y15 blocks breast, pancreatic and neuroblastoma tumor growth in vivo. The pharmacokinetics study in mice demonstrates that, following intraperitoneal administration at 30 mg/kg dose, Y15 is very rapidly absorbed in mice, reaching maximum plasma concentration in 4.8 min. Y15 rapidly metabolizes in mouse and human liver microsomes with half-life t of 6.9 and 11.6 min, respectively. The maximal tolerated dose of single-dose administration of Y15 by oral administration is 200 mg/kg, and the multiple maximum tolerated dose of Y15 is 100 mg/kg by PO during 7 day study. Y15 does not cause any mortality or statistically significant differences in the body weight at 30 mg/kg by IP during 28-day study, and at 100 mg/kg by PO during the 7-day study. There are no clinical chemical, hematological, or histopathological changes in different mice organs at 30 mg/kg by IP during 28 days and at 100 mg/kg dose by PO during 7 days.
