Description
CHS-
828 is a pyridyl cyanoguanidine anti-
tumor agent that has been identified as a competitive inhibitor of Nampt as well as an inhibitor of NF-
κB pathway activity. CHS-
828 has potent cytotoxic effects in human breast (IC
50 = 7.3 nM) and lung cancer (IC
50 = 0.5 nM) cells both
in vitro and
in vivo. In nude mice bearing human tumor xenografts, CHS-
828, at 20-
50 mg/kg/day, inhibits the growth of MCF-
7 breast cancer tumors and induces regression of NYH small cell lung cancer tumors.
