NOVEL FLUORESCENT DYES AND USES THEREOF
-
Page/Page column 37-38, (2011/02/24)
The present invention provides fluorescent dyes that are based on firefly luciferin structure. These dyes are optimally excited at shorter wavelengths and have Stokes shift of at least 50 nm. The fluorescent dyes of the invention are useful for preparation of dye-conjugates, which can be used in detection of an analyte in a sample.
PROCESS FOR PRODUCING OPTICALLY ACTIVE 2-ALKYLCYSTEINE, DERIVATIVE THEREOF, AND PROCESSES FOR PRODUCTION
-
Page/Page column 16, (2008/06/13)
There is provided a process for producing an optically active 2-alkylcysteine or a salt thereof, characterized by allowing cells of microorganism or treated products thereof having an activity of stereoselective hydrolysis of the amide bond of a 2-alkyl-L-cysteinamide or a salt thereof to act on a 2-alkylcysteinamide consisting of a mixture of D- and L-isomers or a salt thereof; and allowing the obtained 2-alkyl-L-cysteine and 2-alkyl-D-cysteinamide to react with an aldehyde or a ketone, or an acetal or ketal thereof, so as to derive therefrom a 4-alkylthiazolidine-4-carboxylic acid or a salt thereof and a 4-alkylthiazolidine-4-carboxamide or a salt thereof, thereby efficiently separating and obtaining a 2-alkyl-L-cysteine or a salt thereof, or a 2-alkyl-D-cysteine or a salt thereof. There is also provided a process for producing a 4-alkylthiazolidine-4-carboxylic acid or a salt thereof from the 2-alkylcysteine or a salt thereof.

A series of β-mono- and β,β-disubstituted cysteins were evaluated in rats as sequestering agents for metabolically generated acetaldehyde (AcH) during the oxidation of ethanol in vivo and compared against D-(-)-penicillamine.Both threo- (5) and erythro-β-
