  Pasteur’s Tweezers Revisited: On the Mechanism of Attrition-Enhanced Deracemization and Resolution of Chiral Conglomerate Solids

  摘要：

  Insights into the mechanism of attrition-enhanced deracemization and resolution of solid enantiomorphic chiral compounds are obtained by crystal size and solubility measurements and by isotopic labeling experiments. Together these results help to deconvolute the various chemical and physical rate processes contributing to the phenomenon. Crystal size measurements highlight a distinct correlation between the stochastic, transient growth of crystals and the emergence of a single solid enantiomorph under attrition conditions. The rapid mass transfer of molecules between the solution and solid phases under attrition is demonstrated, and the concept of a crystal-size-induced solubility driving force is exploited to overcome the stochastic nature of the crystal growth and dissolution processes. Extension to non-racemizing conditions provides a novel methodology for chiral resolution. Implications both for practical chiral separations and for the origin of biological homochirality are discussed.

  Discovery of novel 2-(3-(2-chlorophenyl)pyrazin-2-ylthio)-N-arylacetamides as potent HIV-1 inhibitors using a structure-based bioisosterism approach

  摘要：

  The present work is an extension of our ongoing efforts towards the development and identification of new molecules with anti-HIV activity which have previously led to the discovery of arylazolylthioacetanilides as highly active NNRTIs. In this article, a series of 2-2-(3-(2-chlorophenyl)pyrazin-2-ylthio)-N-arylacetamide derivatives were synthesized and evaluated for in vitro anti-HIV activity. Most of the tested compounds exhibited moderate activities against wild-type HIV-1. Among them, compound 6k showed significant activity against wild-type HIV-1 with an EC50 value of 1.7 mu M, along with moderate activity against wild-type reverse transcriptase (RT). The preliminary structure-activity relationship (SAR) and docking calculations of this new series of compounds were also investigated, which may help designing more potent molecules.

  CXC chemokine receptors 1 (CXCR1) and 2 (CXCR2) have been demonstrated to have critical roles in cancer metastasis. Because they share high homology sequences, it is still unclear how to design selective CXCR1 or CXCR2 antagonists. Based on a pharmacophore model we built, compound 2 bearing a 1,5-dihydro-4H-imidazol-4-one scaffold was identified as a selective CXCR2 antagonist with a low CXCR1 antagonism

  CXC 趋化因子受体 1 (CXCR1) 和 2 (CXCR2) 已被证明在癌症转移中具有关键作用。由于它们具有高度同源性序列，目前尚不清楚如何设计选择性CXCR1或CXCR2拮抗剂。基于我们建立的药效团模型，带有 1,5-二氢-4 H-咪唑-4-酮支架的化合物2被鉴定为具有低 CXCR1 拮抗偏好的选择性 CXCR2 拮抗剂。经过进一步的优化和构效关系研究，化合物C5克服了化合物2的缺点，具有更高的选择性。它表现出优异的口服生物利用度和体外抗癌转移活性。分子蛋白复合物的进一步动态模拟表明，CXCR2的氨基酸残基K320对C5的选择性贡献最大。该研究为设计新型CXCR2选择性拮抗剂提供了重要线索， C5可以作为研究CXCR1和CXCR2生物学功能差异的分子工具。

  The recently discovered technique of deracemization by means of attrition-induced grinding of a solid conglomerate in contact with a solution wherein racemization occurs has been used with a derivative of 2-chlorophenyl glycine, the key chiral component in the synthesis of Clopidogrel (Plavix). Deracemization of the racemate proceeds to a single enantiomer and in essentially absolute enantiomeric excess. Further conversion of enantiomerically pure material to Clopidogrel was achieved in 88% yield.
