The synthesis of methyl 4-(2-octadecylcyclopropen-l-yl)butanoate: a possible inhibitor in mycolic acid biosynthesis
摘要:
The high molecular weight 2-alkyl-3-hydroxy mycolic acids are key structural components of the cell envelope of pathogenic mycobacteria such as Mycobacterium tuberculosis. It has been shown recently that (Z)-tetracos-5-enoic acid is a key initial intermediate in mycolic acid biosynthesis in extracts of Mycobacterium smegmatis. This acid is presumably for-med by desaturation of tetracosanoate, and previous studies on oleic acid biosynthesis suggest that a cyclopropene analogue may be a potential inhibitor. This communication describes the synthesis of methyl 4-(2-octadecylcyclopropen-1-yl)butanoate, which is shown elsewhere to be an inhibitor of the initial stages of mycolic acid synthesis.

(EN) A method, using a multi-phasic solvent system, for the simultaneous purification and separation of different classes of compounds, which may be cell-wall components or derivatives or analogues thereof which may be extracted from a culture of the relevant cells or which may be synthesized. The cell-wall components may be lipid cell-wall components of microbial origin which can be separated from contaminating material as a group.(FR) Cette invention se rapporte à un procédé qui utilise un système de solvants multiphases pour obtenir la purification et la séparation simultanées de différentes classes de composés, qui peuvent être des composants de parois cellulaires ou des dérivés analogues de ceux-ci, pouvant être extraits d'une culture de cellules pertinentes ou pouvant être synthétisés. Ces composants de parois cellulaires peuvent être des composants de parois de cellules lipidiques, d'origine microbienne, qui peuvent être séparés d'une substance contaminante sous la forme d'un groupe.

Synthesis of methyl 3-(2-octadecylcyclopropen-1-yl)propanoate and methyl 3-(2-octadecylcyclopropen-1-yl)pentanoate and cyclopropane fatty acids as possible inhibitors of mycolic acid biosynthesis
(Z)-Tetracos-5-enoic acid is a key intermediate in the biosynthesis of myocobacterial mycolicacids. Recently the methyl ester of its cyclopropene analogue, methyl4-(2-octadecylcyclopropen-1- yl)butanoate, was shown to act as an inhibitor of mycolicacidbiosynthesis. The related analogues methyl 5-(2-octadecylcyclopropen-1-yl)pentanoate and methyl 3-(2-octadecylcyclopropen-1-yl)propanoate have been
