  念珠菌脂肪酶对乙酰氧基苯甲酸酯和苯乙基苯甲酸酯的酶促水解

  摘要：

  来自Candida cylindracea（CCL）的脂肪酶可快速且选择性地使所有三种区域异构体乙酰氧基苯甲酸甲酯脱乙酰。在类似的芳基乙酰氧基苯甲酸酯的酶水解中，乙酰氧基和苯甲酰氧基官能团之间的反应性差异减小，并且芳基间位的甲氧基反转了反应性顺序，从而使化合物为阿司匹林或类似阿司匹林的前药。苯乙基苯甲酸酯的酶促水解的对映选择性的程度与立体异构中心的位置有关。

  dehydroxymethylative functionalization reaction of aliphatic alcohols under mild and catalyst-free conditions, representing a new paradigm for forging various C(sp3)–heteroatom bonds between diverse alkanols and N- or O-centered nucleophiles. In addition, detailed mechanistic investigations have been carried out, revealing that these reactions proceed through a β-scission/anodic oxidation/nucleophilic

  Represented herein is a simple thiol identified as an effective precursor to photochemically form a carbocation. Thanks to the thiyl radical rapid transformation to disulfide, which serves not only to stabilize the generated thiyl radical but also to allow the second electron transfer to form a carbocation. The resulting carbocations, including primary benzylic, secondary, and tertiary carbocations

  A rationale is developed for aspirin prodrugs based on non-acidic latentiated derivatives. Knowledge of the gastro-intestinal liabilities and pharmacological profile is required for this approach whereby aspirin is built into a common ortho ester function of the type 2-substituted 2-methyl-4H-1,3-benzodioxin-4-one with latentiated carboxyl and acetoxy groups. Twelve compounds of this type, ten substituted with various alkoxy and aryloxy groups and two with arylthio groups, have been isolated and characterized. A new synthetic route, comprising the reaction of 2-acetoxybenzoyl chloride with TMS derivatives of the corresponding alcohols and phenols, has been devised for the preparation of some of the compounds while others were prepared according to known methods. Subsequently, the prodrug candidates have been subjected to non-enzymatic hydrolysis for a first rapid screening in vitro. Only 2-tert-butoxy-2-methyl-4H-1,3-benzodioxin-4-one is observed to act as a true proaspirin, releasing aspirin, under these conditions, but analogous compounds with tertiary substituents may display the same behavior, and this chemical approach to aspirin modification may offer a viable rationale for aspirin prodrugs with reduced gastric irritancy or for making "superaspirins".
• Enzymatic hydrolyses of acetoxy- and phenethylbenzoates by Candida cylindracea lipase

  The lipase from Candida cylindracea (CCL) deacetyles rapidly and selectively all three regioisomer methyl acetoxybenzoates. In the enzymatic hydrolyses of analogous aryl acetoxybenzoates, the difference of reactivity between the acetoxy and benzoyloxy functionalities is reduced and a methoxy group in meta position of the aryl group reverses the reactivity order making the compounds aspirin or aspirin-like
