Biological Activity for CB 5083

CB 5083 is a potent p97 inhibitor, inhibiting the D2 ATPase domain (IC₅₀ = 11 nM). CB 5083 shows broad antitumor activity and inhibits tumor growth in vivo. CB 5083 is cytotoxic to A549 cancer cells (IC₅₀ = 680 nM) and reduces cell viablility in a range of colorectal cancer cell lines. Increases CHOP and GRP78 protein levels, upregulates PD-L1 mRNA levels and results in the loss of aggresomes.
