  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.

  Aliphatic ethers 2 and esters 3, which are closely related to antifungal azoles, were synthesized and tested against various strains of Candida. We found that their activity was strongly related to the length of the chains; the best activity was obtained with a C-6 chain for ethers and C-5 or C-6 chains for esters (including the carbonyl group), whereas shorter or longer alkyl chains decreased antifungal efficiency. The biological activity of such compounds could be related to their ability to bind with the lipophilic area near the active site of enzymatic target. The lipophilic character increases with the length of chain, following a linear variation. Thus, even if the activity depends on the lipophilic influence, this particular property is not sufficient to totally explain the antifungal efficiency.
