摘要:
The present invention relates to a novel and efficient chemoenzymatic process of preparation of optically active trans alkyl phenylglycidates. The invention particularly discloses a novel process for the chemoenzymatic synthesis of two enantiomers of trans alkyl phenylglycidate i.e. alkyl(2S,3R)-phenylglycidate and alkyl(2R,3S)-phenylglycidate of formulae 7 and 8 respectively
摘要:
The present invention relates to novel compounds possessing specific hot, pungent and spicy taste when subjected to direct pungency evaluation, which may be useful as food additives and anti-oxidants, however the said compounds do not add to any nutritional value but the synthesised compounds can possess useful pharmacological properties which is expected to find application in new test models for the development of anti-inflammatory drugs, bioavailability enhancers and for the study of hepatic drug metabolising mechanism; also relates to a process for preparing the said compounds.
摘要:
The present invention provides a synergistic composition of bioactive fraction essentially constituting iridoid glucosides, acetyl barlerin and shanzhiside methyl ester isolated from a plant source Barleria prionitis linn along with a process for the isolation of the bioactive fraction, the present invention also relates to a method of treating mammals and humans for hepatotoxicity, stress and immuno-deficiency with the synergistic bioactive composition.
