CB-5083 CB-5083 is a potent, selective, and orally bioavailable p97 AAA ATPase inhibitor with IC50 of 11 nM. Phase 1. In vitro
In A549 cells, CB-5083 causes significant K48 poly-ubiquitinated protein and CHOP accumulation as well as p62 reduction, and kills tumor cells with IC50 of 680 nM.
In vivo
In mice bearing human HCT 116 colon tumor xenografts, CB-5083 (75 mg/kg, p.o.) significantly inhibits tumor growth. In mice bearing established human AMO-1 multiple myeloma and A549 lung carcinoma tumor xenografts, CB-5083 (100 mg/kg, p.o.) also results in significant tumor growth inhibition. Cell Data
