constituents, being also appreciated as synthetic building blocks. This work shows the ability of unspecificperoxygenases (UPOs, EC1.11.2.1) from several fungi, some of them being described recently, to catalyze the oxyfunctionalization of α- and β-ionones and α- and β-damascones. Enzymatic reactions yielded oxygenated products such as hydroxy, oxo, carboxy, and epoxy derivatives that are interesting

The present invention relates to the synthesis of a series of ionone and curcumin derivatives as multi-targeting agents effective against both hormone-sensitive and hormone-independent cancers. In particular, the present invention is directed to a distinct class of bifunctional antiandrogens, which inhibit both AR and IKBkinases (IKK). A series of ionone-based chalcones were synthesised and their in vitro cytotoxicity against prostate cancer cell lines were demonstrated. A series of derivatives formed by reacting ionone-based chalcones and hydrazines demonstrate substantial antiproliferative activities in prostate cancer, breats cancer and lung cancer cell lines.

The absorption maxima of retinyl iminium polyene are more strongly affected by non-conjugated positivecharge located in the vicinity of the β-ionyl moiety (2) than by those located in the vicinity of carbon atoms 12–14(1).
The present invention relates to optimized ketolase coding sequences and corresponding genetic constructs comprising the same, their use for the expression in plants, in particular in plants of the genus Tagetes, to such genetically modified plants and to a process for the preparation of carotenoid products , in particular ketocarotenoid products by culturing the genetically modified plants.
