  Enzyme Fingerprints of Activity, and Stereo- and Enantioselectivity from Fluorogenic and Chromogenic Substrate Arrays

  摘要：

  A series of stereochemically and structurally diverse fluorogenic and chromogenic substrates for hydrolytic enzymes has been synthesized and used to characterize enzyme activity profiles of esterases, lipases, proteases, peptidases, phosphatases, and epoxide hydrolases. The substrates used are particularly resilient to nonspecific reactions due to their mechanism of activation. The activities recorded with the individual substrates are therefore remarkably reproducible, and enable us to use the overall pattern of activity as a specific fingerprint for the enzyme sample. Fingerprints of activity, and enantio- and stereoselectivity are displayed as arrays of color-scale squares that are easily analyzed visually. Such fingerprints might be useful for quality control, enzyme discovery, and possibly for addressing the issue of functional convergence in enzymes.

  This invention has as its object a method for releasing a product by subjecting a compound of Formula (II′): R′ 7 R′ 8 (HX)C 1 -C 2 (YH)R′ 9 R′ 10 to a chemical oxidation that cleaves the bond C 1 -C 2 to obtain the product. In the compound of Formula (II′): R′ 7 to R′ 10 , which are identical or different, correspond to a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted functional group; X and Y, which are identical or different, are an oxygen atom, a sulfur atom, or an amine of Formula —NR 11 R 12 , wherein R 11 is a hydrogen atom, an alkyl group, or a substituted or unsubstituted aryl group, and R 12 is not a hydrogen atom. The invention also has as its object a method for releasing a product that comprises, before the chemical oxidation stage, a first step for preparing the compound of Formula (II′). The released product can be a volatile molecule or an active substance or else a specific product. The invention also relates to a method for detecting the released product as well as its applications, in particular for detecting catalytic or enzymatic activities.

  本发明的目的是通过将式（II'）的化合物暴露于化学氧化作用下，断裂C1-C2键获得产品的方法。在式（II'）的化合物中，R'7到R'10是相同或不同的氢原子、取代或未取代的烷基或取代或未取代的功能基团；X和Y是相同或不同的氧原子、硫原子或式—NR11R12的胺，其中R11是氢原子、烷基或取代或未取代的芳基，而R12不是氢原子。本发明还涉及在化学氧化阶段之前，制备式（II'）化合物的第一步骤的释放产品的方法。释放的产品可以是挥发性分子、活性物质或特定产品。本发明还涉及检测释放产品的方法及其应用，特别是用于检测催化或酶活性。
