studies of a 1,2,4-triazolo-[3,4-b]thiadiazine scaffold, identified in an HTS campaign for selective STAT3 pathway inhibitors, determined that a pyrazole group and specific aryl substitution on the thiadiazine were necessary for activity. Improvements in potency and metabolic stability were accomplished by the introduction of an α-methyl group on the thiadiazine. Optimized compounds exhibited anti-proliferative
在1,2-,3,4-三唑并[3,4- b ]噻二嗪支架上的结构-活性关系研究在针对选择性STAT3途径抑制剂的HTS运动中确定,确定吡唑基和噻二嗪上的特定芳基取代是必要的活动。通过在噻二嗪上引入α-甲基来实现效力和代谢稳定性的改善。优化的化合物表现出抗增殖活性,磷酸化的STAT3水平降低以及对STAT3目标基因的影响。这些化合物代表了针对STAT3途径的进一步药物发现努力的起点。

The present invention is a method for identifying agents which modulate microRNA activity. The invention involves contacting a cell harboring a microRNA and a microRNA binding sequence, which is operably linked to a nucleic acid molecule encoding a reporter protein, with a test agent and determining whether the test agent increases or decreases the expression of the reporter protein thereby identifying a microRNA modulator. Antagonists identified by this screening assay are provided, as are methods for using the same to inhibit microRNA activity and prevent or treat disease.
