摘要:A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.

标 题:Formation of chiral 4-chromanones using chiral pyrrolidines in the presence of acids
发明人：MEDLOCK JONATHAN ALAN; LETINOIS ULLA; NETSCHER THOMAS; BONRATH WERNER
权利人:DSM IP ASSETS BV
摘要:The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of a specific type and of at least one Bransted acid or in the presence a specific chiral compound having a Bransted acid functional group in the molecule.

摘要:Isolated nucleic acid molecules, designated TCMRP nucleic acid molecules, which encode novel TCMRPs from e.g. Phycomitrella patens are described. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing TCMRP nucleic acid molecules, and host cells into which the expression vectors have been introduced. The invention still further provides isolated TCMRPs, mutated TCMRPs, fusion proteins, antigenic peptides and methods for the improvement of production of a desired compound from transformed cells, organisms or plants based on genetic engineering of TCMRP genes in these organisms.
