Heat shock factor 1 (HSF1) is a transcription factor that plays key roles in cancer, including providing a mechanism for cell survival under proteotoxic stress. Therefore, inhibition of the HSF1-stress pathway represents an exciting new opportunity in cancer treatment. We employed an unbiased phenotypic screen to discover inhibitors of the HSF1-stress pathway. Using this approach we identified an initial
热休克因子 1 (HSF1) 是一种转录因子,在癌症中发挥关键作用,包括提供细胞在蛋白毒性应激下生存的机制。因此,抑制 HSF1 应激途径代表了癌症治疗中令人兴奋的新机会。我们采用公正的表型筛选来发现 HSF1 应激途径的抑制剂。使用这种方法,我们基于 4,6-嘧啶支架 (2.00 μM)确定了初始命中 ( 1 )。细胞 SAR 的优化使得抑制剂在 HSF1 表型测定中具有更高的效力(25、15 nM)。4,6-嘧啶25也被证明对 CDK9 酶具有高效能 (3 nM)。
