  dual-targeting drugs has become a new strategy. In this study, we have developed a series of dual-acting agents targeting both estrogen receptor α (ERα) and histone demethylase based on a privileged OBHS pharmacophore scaffold developed previously by our laboratory. These novel OBHS-LSD1i conjugates showed excellent ERα binding affinity and selectivity, and exhibited potent inhibitory activity against lysine

  乳腺癌是一种多因素疾病，因此越来越多的药物联合疗法被用于治疗。但是，药物联合治疗存在不可否认的缺点。因此，开发新型的双重靶向药物已经成为一种新的策略。在这项研究中，我们基于实验室先前开发的OBHS药效基团支架，开发了一系列针对雌激素受体α（ERα）和组蛋白脱甲基酶的双作用剂。这些新颖的OBHS-LSD1i共轭物表现出优异的ERα结合亲和力和选择性，并表现出对赖氨酸特异性脱甲基酶1（LSD1）的有效抑制活性。与4-羟基他莫昔芬体外相比，几种缀合物在MCF-7乳腺癌细胞系中显示出更高的抗增殖功效。其中，最佳化合物11g对LSD1和MCF-7细胞表现出有效的抑制活性，IC50值分别为1.55μM和8.79μM。流式细胞术分析11g的凋亡表明这种类型的化合物对MCF-7细胞的影响部分是由诱导凋亡引起的。而且，11g与ERα的分子对接以及LSD1 / CoREST配合物的活性位点为理解这类化合物与靶

  An operationally simple protocol for direct N- and O-difluoromethylation of 2-pyridones, quinolinones, and isoquinolinones using commercially available TMSCF2Br is disclosed. The chemoselectivity is modulated by simple variations in temperature, solvent, and strength of the base. Diverse, synthetically relevant functional groups are tolerated, including functional groups that have reported reactivity

  phosphatase SHP2 is an oncoprotein associated with cancer as well as a potential immune modulator because of its role in the programmed cell death PD-L1/PD-1 pathway. In the preceding manuscript, we described the optimization of a fused, bicyclic screening hit for potency, selectivity, and physicochemical properties in order to further expand the chemical diversity of allosteric SHP2 inhibitors. In this

  蛋白质酪氨酸磷酸酶SHP2是与癌症相关的癌蛋白，也是一种潜在的免疫调节剂，因为它在程序性细胞死亡PD-L1 / PD-1途径中发挥了作用。在前面的手稿中，我们描述了针对功效，选择性和理化特性的融合双环筛选命中方法的优化，以进一步扩大变构SHP2抑制剂的化学多样性。在本手稿中，我们描述了我们方法的进一步扩展，通过对SAR的理解和基于结构的设计，将融合的双环系统转变为新型的单环嘧啶酮支架。这些研究导致了对SHP394（1）的鉴定，SHP394是一种口服有效的SHP2抑制剂，具有高亲脂性，增强的药效和增强的药代动力学特性。我们还报告了其他具有良好药代动力学和药效学特征的嘧啶酮类似物。总体而言，这项工作改进了我们先前描述的变构抑制剂，并举例说明并扩展了通过变构机理抑制SHP2的允许化学模板的范围。
