化合物Chetomin T6804

Product Introduction
Bioactivity


英文名: Chetomin

描述: Chetomin (BRN0077366) 是球毛壳菌的活性成分，是一种无毒的非小细胞肺癌干细胞靶向分子。它是一种热休克蛋白90/缺氧诱导因子1α 途径的抑制剂。

细胞实验: In RT-PCR and clonogenic survival experiments, chetomin is added in a concentration of 150 nM to fully supplemented medium four hours before treatment with hypoxia. HT 1080 cells are then transferred to the hypoxic workstation (0.1% O2, 12 h) or to the well-humidified incubator (12 hours) without changing medium. HT1080 cells are thus treated for 16 hours with chetomin (150 nM) prior to radiation treatment. (Only for Reference)

体外活性: HIF-1 (hypoxia-inducible factors 1) is transcription factor which respond to changes of cellular environment oxygen[2]. Chetomin selectively inhibits HIF-1 activities through disruption of the interaction of HIF-1 with its transcriptional coactivator p300. HIF-1 inhibition by chetomin effectively reduces hypoxia-dependent transcription and radiosensitizes hypoxic HT 1080 human fibrosarcoma cells in vitro[1]. Chetomin attenuates the hypoxia-induced radioresistance of malignant glioma cell lines U251 mg (DMF10: 1.35 and 1.18) and U343 mg (DMF10: 1.78 and 1.48)[3]. Targeting of HIF-1 using chetomin abolishes the differentiation-inhibitory effect of hypoxia-inducible factor-1α[4].

体内活性: Administration of chetomin in combination with forskolin significantly suppresses malignant glioma growth in an in vivo xenograft model [4]. Che-M(chetomin loaded micelles) dramatically inhibits embryonic angiogenesis, tumor-induced angiogenesis and tumor growth in zebrafish. In mouse model, Che-M suppresses tumor growth and prolongs the survival in the subcutaneous CT26 tumor model [5].
