IT-139, sodium trans-[tetrachlorobis(1H-indazole)ruthenate(III)], is an intravenously administered small molecule compound. In preclinical anti-tumor and mechanism of action studies, IT-139 showed activity against a broad range of tumor types, including those which are resistant to standard anti-cancer agents (e.g., platinums, vinca alkaloids, taxanes, anthracyclines). This activity is believed to arise from IT-139's novel mechanism of action that targets the GRP78 pathway. It was found that up-regulation of GRP78 is a key cancer cell survival pathway. Downregulation of GRP78 using IT-139 removes this resistance pathway allowing for chemotherapy and immuno-oncology agents to be more effective in treating cancer.
IT-139,反式-[四氯双(1H-吲唑)钌酸钠(III)],是一种静脉注射小分子化合物。在临床前抗肿瘤和作用机制研究中,IT-139 对多种类型的肿瘤具有活性,包括对标准抗癌药物(如铂类、长春花生物碱、紫杉类、蒽环类)具有抗药性的肿瘤。据信,这种活性源于 IT-139 针对 GRP78 通路的新作用机制。研究发现,GRP78 的上调是癌细胞生存的关键途径。使用 IT-139 下调 GRP78 可以消除这一抗药性途径,从而使化疗和免疫肿瘤学药物更有效地治疗癌症。
