摘要： Amyloid binding compounds which are derivatives of Chrysamine G, pharmaceutical compositions containing, and methods using such compounds to identify Alzheimer's brain in vivo and to diagnose other pathological conditions characterized by amyloidosis, such as Down's Syndrome are described. Pharmaceutical compositions containing Chrysamine G and derivatives thereof and methods using such compositions to prevent cell degeneration and amyloid-induced toxicity in amyloidosis associated conditions are also described. Methods using Chrysamine G derivatives to stain or detect amyloid deposits in biopsy or post-mortem tissue are also described. Methods using Chrysamine G derivatives to quantify amyloid deposits in homogenates of biopsy and post-mortem tissue are also described.

摘要： A process for the preparation of disazo pigments by which coupling can be attained in an enhanced conversion; and disazo pigments prepared by this process and excellent in transparency, sharpness, staining power and gloss. This process is characterized by continuously pouring an aqueous solution containing a coupler component of the general formula (I) and an aqueous solution of a tetrazo component derived from a benzidine into an aqueous acid solution put in a batch-wise agitated tank at a mole ratio of the coupler to the tetrazo component of 2 : 0.8 to 0.99 to conduct coupling: formula (I), wherein X, Y and Z are each independently H, CH3, OCH3 or C1.

摘要： An object that is to be achieved by the present invention is to provide an azo pigment having excellent transparency, suitable dispersibility, and a low viscosity, an ink, and the like. An azo pigment according to the present invention has a zeta potential of -80 to -30 mV in isopropanol (IPA). The content of a metal element in the azo pigment is preferably 0.05 to 2.00 parts by mass relative to 100 parts by mass of the azo pigment. The metal element is preferably an iron element. The ratio (Fe/C) of the concentration Fe (atomic%) of an iron element in the surfaces of particles of the azo pigment to the concentration C (atomic%) of a carbon element in the surfaces of the particles of the azo pigment which are determined by X-ray photoelectron spectroscopy is preferably 0.20 or less.
