Activity of MAC-321 (i.v. and p.o.) in PTX-resistant xenograft tumor models in vivo.
Activity of MAC-321 (i.v. and p.o.) in PTX-resistant xenograft tumor models in vivo. Female nu/nu mice were given injections of 6 × 106 DLD-1 colon carcinoma cells, 5 × 106 KB-8-5 cells, or five fragments of MX-1W breast carcinoma. Animals bearing DLD-1 staged tumors were treated i.v. (A) or p.o. (B) with vehicle or at the doses of MAC-321 indicated on the day after reaching approximately 100 mg in size. In addition, DLD-1 xenografts were also treated i.v. with 25 mg/kg of DTX on days 1, 5, and 9. Animals bearing KB-8-5 (C) or MX-1W (D) staged tumors were treated with either vehicle, 70 mg/kg MAC-321 p.o., or 70 mg/kg MAC-321 i.v. on day 1. Sixty milligrams per kilogram PTX were administered i.v. on days 1, 5, and 9 (C and D). *, P ≤ 0.01 and #, P ≤ 0.02 as determined by Student's two-tailed t test.
