  收敛，可扩展和立体选择性合成吡咯CYP51抑制剂

  摘要：

  唑基CYP51抑制剂的研究和开发是跨生物化学，药理学和传染病学科的活跃研究领域。体外和体内研究的支持要求开发出鲁棒的不对称途径，以制备此类化合物的单个对映体产物。在这里，我们描述了对VNI和VFV的可扩展和对映选择性合成，VNI和VFV是原生动物固醇14α-脱甲基酶（CYP51）的两种有效抑制剂，目前正考虑用于Chagas病的临床试验。关键的转化是雅各布森水解动力学拆分（HKR）反应。合成路线的实用性通过制备> 25 g的VNI和VFV单一对映体来说明。

  Asymmetric Chemoenzymatic Synthesis of Miconazole and Econazole Enantiomers. The Importance of Chirality in Their Biological Evaluation

  摘要：

  A simple and novel chemoenzymatic route has been applied for the first time in the synthesis of miconazole and econazole single enantiomers. Lipases and oxidoreductases have been tested in stereoselective processes; the best results were attained with oxidoreductases for the introduction of chirality in an adequate intermediate. The behaviors of a series of ketones and racemic alcohols in bioreductions and acetylation procedures, respectively, have been investigated; the best results were found with alcohol dehydrogenases A and T, which allowed the production of (R)-2-chloro-1-(2,4-dichlorophenyl)ethanol in enantiopure form under very mild reaction conditions. Final chemical modifications have been performed in order to isolate the target fungicides miconazole and econazole both as racemates and as single enantiomers. Biological evaluation of the racemates and single enantiomers has shown remarkable differences against the growth of several microorganisms; while (R)-miconazole seemed to account for most of the biological activity of racemic miconazole on all the strains tested, both enantiomers of econazole showed considerable biological activities. In this manner, (R)-econazole showed higher values against Candida krusei, while higher values were observed for (S)-econazole against Cryptococcus neoformans, Penicillium chrysogenum, and Aspergillus niger.

  The preferred absolute configuration of two series of F1F0-ATP synthase inhibitors was determined. Although the configuration of the active enantiomer in each series is different, each series presents the same 'triaryl' pharmacophore to the enzyme binding site. (c) 2005 Elsevier Ltd.
