The present invention concerns compounds, compositions containing these compounds, and methods of using these compounds and compositions as inhibitors of Stat3 signaling, Stat3 dimerization, Stat3-DNA binding, Stat5-DNA binding, and/or aberrant cell growth in vitro or in vivo, e.g., as anti-cancer agents for treatment of cancer, such as breast cancer. The compounds of the invention include, but are not limited to, NSC 74859 (S31-201), NSC 42067, NSC 59263, NSC 75912, NSC 11421, NSC 91529, NSC 263435, and pharmaceutically acceptable salts and analogs of the foregoing. Other non-malignant diseases characterized by proliferation of cells that may be treated using the compounds of the invention, but are not limited to, cirrhosis of the liver; graft rejection; restenosis; and disorders characterized by a proliferation of T cells such as autoimmune diseases, e.g., type 1 diabetes, lupus and multiple sclerosis. The invention further includes an in-vitro screening test for the presence of malignant cells in a mammalian tissue; a method of identifying inhibitors of constitutive Stat3 activation, Stat3-DNA binding, Stat5-DNA binding, and/or Stat3 dimerization; and a method of identifying anti-cancer agents.
本发明涉及化合物、含有这些化合物的组合物以及使用这些化合物和组合物作为Stat3信号通路、Stat3二聚化、Stat3-DNA结合、Stat5-DNA结合和/或体外或体内异常细胞生长的抑制剂的方法,例如作为治疗癌症,如乳腺癌的抗癌剂。本发明的化合物包括但不限于NSC 74859(S31-201)、NSC 42067、NSC 59263、NSC 75912、NSC 11421、NSC 91529、NSC 263435以及其药学上可接受的盐和类似物。其他非恶性疾病,其特征为细胞增殖,可以使用本发明的化合物进行治疗,但不限于肝硬化、移植排斥反应、再狭窄以及T细胞增殖的疾病,例如自身免疫性疾病,如1型糖尿病、狼疮和多发性硬化等。本发明还包括一种用于检测哺乳动物组织中恶性细胞存在的体外筛选测试;一种识别组成性Stat3激活、Stat3-DNA结合、Stat5-DNA结合和/或Stat3二聚化抑制剂的方法;以及一种识别抗癌剂的方法。
