  Evaluation and synthesis of amino-hydroxy isoxazoles and pyrazoles as potential glycine agonists

  摘要：

  Except for structurally similar small amino acids, such as alanine, beta-alanine, and serine, compounds acting as glycine-receptor agonists are an unknown class of pharmacological agents. To investigate the potential of small, substituted heterocycles to act as glycine agonists, we have evaluated the similarities between glycine and a series of hydroxy- and amino-substituted pyrazoles and isoxazoles through complementary molecular modeling techniques. Using a "scorecard approach" to determine the overall similarity of projected agonist structures to glycine, we prioritized synthesis and subsequently prepared several novel derivatives. The biological activity of these compounds was compared to that of glycine by using a [3H]strychnine-mediated glycine receptor binding assay. Despite the close similarity in the calculated parameters when compared to glycine, no significant receptor-binding activity was observed for the targeted analogues. These results illustrate the structurally exacting nature of the glycine receptor.

  at a HTS assay of scavengers is able to selectively and efficiently cleave the PS bond of organophosphorus nerve agents and by this provides non‐toxic phosphonic acid has been designed and synthesised. The previously described pro‐fluorescent probes were based on a conventional activated POaryl bond cleavage, whereas our approach uses a self‐immolative linker strategy that allows the detection of phosphonothioase

  一种针对清除剂的HTS分析的新型前荧光探针能够选择性和有效地裂解有机磷神经毒剂的PS键，从而设计并合成了无毒的膦酸。先前描述的亲荧光探针是基于传统的活性P  O芳基键裂解，而我们的方法使用自脱落接头策略，其允许phosphonothioase活性的检测相对于非活化的P  1-8烷基键。此外，我们还开发并优化了高通量筛选分析方法，以选择可以有效水解高毒性V的去污剂（化学或生物化学清除剂）。型神经毒剂。在一个小的α-亲核试剂库上进行的初步筛选使我们能够鉴定出一些初步的“命中”，其中吡啶醛肟，α-氧代肟，异羟肟酸和活性较低但较原始的a胺肟是最有前途的。通过使用PhX作为底物进一步证实了它们的选择性磷酸硫代磷酸酶活性，因此它们为合成更有效的V神经剂清除剂提供了新的见解。
