CUDC-427 is a potent second-generation pan-selective IAP antagonist, used for treatment of various cancers.

In Vitro

GDC-0917 (0.1 nM-10 μM) induces reduction of cIAP1 levels in PBMCs in a concentration-dependent manner showing greater than 80% inhibition at concentrations greater than 0.1 µM (56.5 ng/mL)[1].

In Vivo

GDC-0917 (0.08-16.3 mg/kg) exhibits antitumor activity in a dose dependent manner in the MDA-MB-231-X1.1 Breast Cancer Xenograft, and GDC-0917 is well tolerated, with all dose groups experiencing a <11% decrease in mean body weight. GDC-0917 has low to moderate clearance in the mouse (12.0 mL/min/kg), rat (27.0 mL/min/kg), and dog (15.3 mL/min/kg), and high clearance in the monkey (67.6 mL/min/kg). Oral bioavailability is lowest in monkeys compared with other species[1].

Animal Administration

Briefly, 10 million MDA-MB-231-X1.1 breast adenocarcinoma cells resuspended in Hank’s balanced salt solution and Matrigel (1:1, v/v) are implanted subcutaneously into the upper right flank of female SCID.bg mice. MDA-MB-231-X1.1 cells are MDA-MB-231 cells that are selected for improved in vivo growth rates. When tumor volumes reach approximately 100-300 mm3, mice are assigned to treatment groups to get a similar mean tumor size for each treatment group. Treatment groups (n=5 per group) are administered once daily oral doses of vehicle (15% hydroxypropyl-β-cyclodextrin, 20 mM succinic acid in water), 0.08, 0.17, 0.34, 0.68, 1.36, 2.72, 5.43, 10.87, or 16.30 mg/kg of GDC-0917 for 21 days. Tumor volumes are measured in two dimensions (length and width) using Ultra Cal IV calipers. Tumor sizes and body weights are recorded twice weekly, and the mice are regularly observed over the course of the study. Mice are euthanized if their tumor volume exceeds 2000 mm3 or if their body weight drops by more than 20% of the starting weight.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
