CBL0137

Research use only, not for human use.

CBL0137 (Curaxin CBL0137) is a histone chaperone FACT (facilitates chromatin transcription) and MYC signal inhibitor that markedly reduced tumor initiation and progression in vivo.

CBL0137 (Curaxin CBL0137) is a histone chaperone FACT (facilitates chromatin transcription) and MYC signal inhibitor that markedly reduced tumor initiation and progression in vivo; simultaneously activates p53 and inhibits NF-κB without causing detectable genotoxicity, causes phosphorylation of p53 Ser(392) by CK2 and inhibition of NF-κB-dependent transcription in neuroblastoma cells; eradicates drug resistant cancer stem cells and potentiates efficacy of gemcitabine in preclinical models of pancreatic cancer.Brain Cancer Phase 1 Clinical.

Treatment with CBL-0137 leads to complete absence of living cells at concentrations above 2.5 μM. CBL-0137 causes a greater reduction in the number of colonies formed of not only MiaPaCa-2 cells when combined with gemcitabine, but also gemcitabine-resistant PANC-1 cells. Treatment of human pancreatic cancer cells with CBL-0137 results in a dose dependent reduction of protein and mRNA levels of RRM1 and RRM2. CBL-0137 is able to prevent gemcitabine induced expression of RRM1 and RRM2 on mRNA and protein levels.

The CBL-0137 monotherapy group and the CBL-0137-gemcitabine combination group samples show large necrotic fields, numerous apoptotic bodies and loss of tumor cells. Sub-optimal doses of 50 to 60 mg/kg CBL-0137 causes similar enhancement of gemcitabine antitumor activity as that produced by the maximum tolerated dose (MTD) of 90 mg/kg as indicated by the lack of statistically significant differences among the combination groups. CBL0137 hydrochloride inhibits FACT function through depletion of the pool of active FACT involved in transcription elongation. CBL-0137, given by oral gavage at a nontoxic dose of 30 mg/kg per day on a 5 days on/2 days off schedule, suppresses tumor growth in xenografts of colon (DLD-1), renal cell carcinoma (Caki-1), and melanoma (Mel-7) tumor cell lines and transplanted surgical samples from patients with pancreatic ductal adenocarcinoma.
