Abstract: The invention features compositions and methods for inhibiting the Pin1 protein, and the treatment of disorders characterized by elevated Pin1 levels.

Abstract: The present invention provides a novel sulfonic acid group-containing diamine compound represented by formula (1) below, and a method for producing the same. This compound has a fluorene skeleton with sulfonic acid groups or derivatives thereof. In this compound, a substituent having an amino group is bonded to each of carbon atoms at the 2-position and the 7-position in the skeleton, and no substituent is bonded to a carbon atom at the 9-position in the skeleton. A in formula (1) denotes an optionally-substituted divalent aliphatic group (having a carbon number of 10 or less) or an optionally-substituted divalent aromatic group (having the number of rings of 4 or less), for example.

Abstract: Disclosed is an arylsulfonic acid compound characterized by being represented by formula (1). By using this compound as an electron-acceptor material, highly uniform film formability can be achieved. By using a thin film containing the arylsulfonic acid compound in an OLED device or a PLED device, there can be obtained excellent EL device characteristics such as low driving voltage, high luminous efficiency and long life. (In the formula, X represents O, S or NH; Ar represents an aryl group; and n represents the number of sulfonic groups, which is an integer of 1-4.

Abstract: The present invention is generally directed to thiol quantitation assays, methods of performing the assays, and compounds used in the assays. It is more specifically directed to assays that include one or more disulfides and related molecules and methods. The disulfides contain a FRET pair.

Abstract: The invention describes the synthesis and use of photoactivated (or caged) fluorescent dyes. Upon illumination at less than about 400 nm the caged dyes release highly fluorescent, water soluble hydroxypyrenesulfonic acid dyes according to the following equation: ##STR1## X, Y, and Z are independently sulfonic acid, a sulfonic acid salt, a hydroxyl group, or hydrogen, with at least one of X, Y, and Z being a sulfonic acid or sulfonic acid salt. LINK is either an ether linkage or a carbonate linkage. BLOCK is a caging group whose photolysis results in liberation of a free hydroxypyrenesulfonic acid dye.The caged fluorescent dyes are useful for application in aqueous solutions, including fluids of biological origin. The caged dyes of the present invention are especially useful for flow tagging velocimetry.

Abstract: Compounds of formula ##STR1## wherein X is long-chain alkyloxy, long-chain alkylamino or long-chain dialkylamino,M is alkali metal, pyridinium or ammonium,Y is hydroxy or long-chain alkyloxy,which are especially useful in photometric and fluorimetric investigations of lipids and lipid-water interactions and of cationic biomolecules such as nicotine adenine dinucleotide.
