How to use
In Vitro:
CH0793076 (TP3076) (6 days at 37°C) shows antiproliferative activity against PC-6/BCRP and PC-6/pRC cells, with IC50s of 0.35 and 0.18 nM, respectively.
In Vivo:
TP300 (1-100 mg/kg; bolus intravenous injection once per week for 3 weeks, for a total of three doses), a water-soluble prodrug of CH0793076, shows more than 50% of tumor growth inhibition in all nine models, regardless of the expression of BCRP (WiDr, HT-29, NCI-H460 and AsPC-1, HCT116, COLO 201, HCT-15, Calu-6 and NCI-N87).
