developmental space of C-terminal inhibitors is limited. It was hypothesized that the combination of two previously identified scaffolds into a single structure could provide a platform for which to probe the three-dimensional space within the Hsp90 C-terminal binding pocket. The resulting chimeric compounds displayed anti-proliferative activity at low micromolar concentrations and manifested inhibitory activity

copper-catalyzed enantioselective aza-Freidel-Crafts reaction between phenols and N-sulfonyl aldimines that provides chiral secondary benzylamines in good to excellent yields and excellent enantioselectivities (up to 99% ee) is disclosed. In particular, excellent scope with alkylimines was observed for the first time. The synthetic utility of the products was demonstrated in the first enantioselective synthesis

replaced with the biphenyl core without compromising activity. Based on these prior studies, a series of alkylamino biphenylamides was designed, synthesized and evaluated for anti-proliferative activity against two breast cancer cell lines. SAR studies demonstrated that the incorporation of an alkylamino side chain onto the biphenyl core improved anti-proliferative activity and resulted in compounds that
Hsp90 是抗癌药物开发的一个有前景的治疗靶点,因为它在与癌症的所有十个标志相关的蛋白质的稳定性和功能中发挥着不可或缺的作用。 Novobiocin 是一种香豆素类抗生素,是第一个被鉴定的天然产物,其靶向 Hsp90 C 末端结构域并表现出抗增殖活性 (SKBr3 IC 50 ∼ 700 μM)。随后对新生霉素的结构研究产生了对多种癌细胞系具有显着改善的抗增殖活性的类似物。为了开发更有效和多样化的类似物,最近发现新生霉素的香豆素环可以被联苯核心取代,而不会影响活性。基于这些先前的研究,设计、合成了一系列烷基氨基联苯酰胺,并评估了其对两种乳腺癌细胞系的抗增殖活性。 SAR 研究表明,将烷基氨基侧链掺入联苯核心可提高抗增殖活性,并通过 Hsp90 抑制产生表现出亚微摩尔至中纳摩尔活性的化合物。重要的是,这些研究表明中心核心周围存在亲水区域,可用于设计新的抑制剂。
Direct Detection of Hardly Detectable Hidden Chirality of Hydrocarbons and Deuterated Isotopomers by a Helical Polyacetylene through Chiral Amplification and Memory
hardly detectable hidden chirality of saturated tertiary or chiroptical quaternary hydrocarbons, and deuterated isotopomers. In sharp contrast to the previously reported sensory systems, the chirality detection by the polyacetylene relies on an excess one-handed helix formation induced by the chiral hydrocarbons and deuterated isotopomers via significant amplification of the chirality followed by its static
