CCF-642 is a protein disulfide isomerase (PDI) inhibitor. CCF642 exhibited a submicromolar IC50 in 10 of 10 multiple myeloma cell lines. In vitro, CCF642 inhibited PDI reductase activity about 100-fold more potently than the structurally distinct established inhibitors PACMA 31 and LOC14. CCF642 displayed potent efficacy in an aggressive syngeneic mouse model of multiple myeloma and prolonged the lifespan of C57BL/KaLwRij mice engrafted with 5TGM1-luc myeloma, an effect comparable to the first-line multiple myeloma therapeutic bortezomib.

How to use

In Vitro:

CCF642 (3 μM; 0.5-6 hours) increases PERK dimerization by phosphorylation and IRE1-α oligomerization within 30 minutes in KMS-12-PE confirming accumulation of misfolded ER proteins. CCF642, a bone marrow-sparing compound, exhibits a submicromolar IC50 in 10 of 10 multiple myeloma cell lines (MM1.S, MM1.R, KMS-12-PE, KMS-12-BM, NCI-H929, U266, RPMI 8226, JJN-3, HRMM.09-luc, 5TGM1-luc).

In Vivo:

CCF642 (10 mg/kg; i.p.; three times a week; for 24 days) significantly prolongs life of 5TGM1-luc-bearing mice and suppresses 5TGM1-luc growth as determined by life imaging.
