CCF642 is a potent protein disulfide isomerases (PDI) inhibitor with an IC50 of 2.9 μM. CCF642 causes acute endoplasmic reticulum (ER) stress in multiple myeloma cells accompanied by apoptosis-inducing calcium release. CCF642 has broad anti-multiple myeloma activity.
IC50&Target
IC50: 2.9 μM (PDI)
体外研究
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).
