The present invention concerns compounds and their use to treat cell proliferative diseases such as cancer. In general aspects, compounds of the present invention are tyrphostin-like in structure. Compounds of the present invention, in certain embodiments, display significant potency by causing, for example, inhibition of Stat3 activation, reduction in c-myc protein levels and/or induction of apoptosis in tumor cells. In general aspects, compounds of the present invention induce one or more of these activities at nanomolar concentrations and typically function through a unique mechanism involving the induction of stress granules that bind specific signaling molecules and prevent them from participating in signal transduction and oncogenesis.
本发明涉及化合物及其用于治疗细胞增殖性疾病,如癌症。在一般方面,本发明的化合物在结构上类似于酪氨酸激酶抑制剂。在某些实施例中,本发明的化合物通过诱导应激颗粒结合特定信号分子并阻止它们参与信号转导和肿瘤发生,从而表现出显著的效力,例如抑制Stat3激活、降低c-myc蛋白水平和/或诱导肿瘤细胞凋亡。在一般方面,本发明的化合物在纳摩尔浓度下诱导这些活性中的一个或多个,并通常通过诱导应激颗粒的独特机制发挥作用,这些应激颗粒结合特定信号分子并防止它们参与信号转导和肿瘤发生。
