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 an aromatic substituted pentadienoic acid amides and there use in combination of specific amounts of aromatic amides i.e. 4-alkyl-5-(substituted phenyl)-2(E),4(E)-pentadienoic acid amides, its geometrical isomers or their dihydro or tetrahydro derivatives and an anti-infective drug useful in potentiating the bioefficacy of antiinfective drug. The combination of the present invention is useful in the treatment of certain infections and disease at lower concentration of anti-infectives necessary to inhibit the growth of microbial strains and may also find applications in reducing the resistance in microorganisms.

摘要:
The present invention relates to a facile, highly efficient and economical process for the preparation of optically active N-benzyl-3-hydroxypyrrolidine in high yield from a naturally occurring alkaloid vasicine. The natural alkaloid vasicine is used as a precursor of (S)—N-benzyl-3-hydroxypyrrolidine and (R)—N-benzyl-3-hydroxypyrrolidines which can easily be sourced from the medicinal plant Adatoda vasica by the method known in the art and transformed to optical isomers (R) and (S)—N-benzyl-3-hydroxypyrrolidine by the method described in the present invention.

摘要:
A new and distinct variety of Cymbopogon commutatus grass is provided. The new variety was discovered during a mass selection program that was carried out in India in a cultivated area, and offers significant advantages over a typical plant of the species. More specifically, the new variety exhibits superior drought tolerance, a vigorous perennial growth habit, and lighter green leaves than typically exhibited by the species. The plant produces an essential oil having an enhanced geraniol and geranyl acetate content that is useful to form perfumes and in flavor applications. Asexual reproduction can be readily carried out by the rooting of slips.
摘要:
The present invention relates to use of compounds of general formula 1 for anticancerous activity, wherein the said compound being derived semi-synthetically from natural triterpenoic acids known as boswellic acids by the induction of apoptosis thereof cytotoxicity and anti-cancer activity displayed by semi-synthetic analogues of natural triterpenes, known as Boswellic acids. These compounds may be used for the treatment of cancer, alone or in combination with pharmaceutically acceptable or other carriers, displaying cytotoxicity and anti-cancer activity for colon, prostrate, liver, breast, central nervous system (CNS), leukemia and malignancy of other tissues, including ascites and solid tumors. The cancer cell death is mediated by induction of apoptosis and inhibition of cell proliferation at specific doses.
