Description

Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/21443232

AT-406 (DEBIO-1143, SM-406), is a potent and orally bioavailable Smac mimetic and an antagonist of the inhibitor of apoptosis proteins (IAPs). AT-406 inhibits cancer cell growth in various human cancer cell lines. It has good oral bioavailability in mice, rats, non-human primates, and dogs, is highly effective in induction of apoptosis in xenograft tumors, and is capable of complete inhibition of tumor growth. Debiopharm under a licence from Ascenta Therapeutics is developing AT-406 for the treatment of cancers.

Sample Use Guides

In Vivo Use Guide

5 to 900 mg AT406 (DEBIO1143) was given orally once daily on days 1-5 every 2 or 3 weeks until disease progressed or patients dropped out: DEBIO1143 was well tolerated at doses up to 900 mg and elicited pharmacodynamics effects at doses greater 80 mg.

Route of Administration: Oral

In Vitro Use Guide

AT-406 potently inhibits cell growth in the MDA-MB-231 breast and SK-OV-3 ovarian cancer cell lines with IC50 = 144 nM and 142 nM, respectively. AT-406 effectively induces cell death in a time- and dose-dependent manner, more than 50% of the MDA-MB-231 cancer cells underwent cell death upon treatment at 1 μM for 24 hours.
