CBL0137
CAS No. : 1197996-80-7
MCE 国际站:CBL0137
产品活性:CBL0137 是一种 curaxin 化合物,是一种组蛋白伴侣促进染色质转录 (FACT) 抑制剂。CBL0137 下调 NF-?B 并激活 p53。CBL0137 可恢复组蛋白 H3 乙酰化和三甲基化。CBL0137 是一种抗癌剂。CBL0137 诱导癌细胞凋亡 (apoptosis)。
研究领域:Epigenetics | Apoptosis | NF-κB
作用靶点:Histone Acetyltransferase | MDM-2/p53 | NF-κB
In Vitro: 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.
In Vivo: 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.
