  Accelerated hydrolysis of α-halo and α-cyano pyridinium relative to uracil derivatives: a model for ODCase-catalyzed hydrolysis of 6-cyanoUMP

  摘要：

  alpha-Halo and alpha-cyano pyridiniums were found to undergo facile hydrolysis, in contrast to the sluggish reactions of corresponding uracils. The greatly enhanced rates found with pyridinium compounds have indicated a possible source of the rate acceleration seen in the hydrolysis of 6-cyanouridine 5'-monophosphate catalyzed by orotidine 5'-monophosphate decarboxylase.

  One aspect of the present invention relates to reactive compositions and methods of use thereof, wherein a metal oxide cluster is used to connect a reactive group (or groups) to the surface of a substrate. In certain embodiments, the reactive group in the compositions decomposes organophosphate agents through nucleophilic hydrolysis. In certain embodiments, the reactive group in the compositions is bactericidal. Remarkably, the use of metal oxide clusters in the disclosed compositions and methods permits incorporation of higher quantities of nucleophilic and bactericidal groups without the difficulties associated with having to pretreat the substrate prior to its association with the reactive groups.

  本发明的一个方面涉及反应性组合物及其使用方法，其中金属氧化物簇用于将反应性基团（或基团）连接到基底表面上。在某些实施例中，组合物中的反应性基团通过亲核水解分解有机磷酸酯剂。在某些实施例中，组合物中的反应性基团具有杀菌作用。值得注意的是，所述组合物和方法中使用金属氧化物簇允许将更多的亲核和杀菌基团纳入其中，而无需在与反应性基团结合之前对基底进行预处理。
