Abstract: The present invention relates to novel spiro derivatives of parthenin prepared by the dipolar cycloaddition of various dipoles viz, benzonitrile oxides, nitrones, azides, nitrile ylide diazoalkane, nitrile imide, ozone, azomethine imides, azomethine ylides etc. with exocyclic double bond of C ring (?-methylene-?-butyrolactone). Representative compounds have been screened for their anticancer activity against different cancer cell lines. ICs0 value of these analogues varies between 4.3 ?M to 93 ?M. A mechanistic correlation of their anticancer activity has been described. The results of the cytotoxicity test of the compounds studies indicated that the ?,?-unsaturated ketonic moiety in parthenin plays an important role in the maintenance of the high level of cytotoxicity.

Abstract: 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.

Abstract: 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.
