Publication number: 20100076040Abstract: The invention relates to a method for producing bisbenzoxazoles that are interconnected by means of a system of conjugated double bonds, according to which o-aminophenols are reacted with dicarboxylic acids, the carboxyl groups of which are interconnected via a double bond or a system of conjugated double bonds, to form an ammonium salt, said ammonium salt being converted in the presence of dehydrogenating catalysts and solvents with a low dielectric loss into benzoxazol by means of microwave radiation.Type: ApplicationFiled: October 5, 2007Publication date: March 25, 2010Applicant: Clariant Finance Wickhams CayInventor: Mathias KRULL

Publication number: 20100015054Abstract: Disclosed are reactive polyfluoro benzoxazole polymethine dyes that are useful for labelling and detecting biological and other materials. The dyes are of formula (I): in which X is selected from the group consisting of —O—, —S— and at least one of groups R1 and R2 is the group -L-Rx or -L-Rp, where L is a linking group, Rx is a group suitable for covalent attachment of the dye to a component and Rp is a component; and at least one of groups R3, R4, R5, R6, R7, R8, R9 and R10 comprises fluorine. The use of polymethine dyes substituted by fluorine and having additional substitution by sulphonic acid groups, for labelling biological target molecules results in a labelled product in which there is reduced dye-dye aggregation and improved photostability, compared with cyanine dyes having no such substitutions.Type: ApplicationFiled: October 4, 2007Publication date: January 21, 2010Applicant: GE HEALTHCARE UK LIMITEDInventor: Najeeb Said

Publication number: 20090304598Abstract: The invention relates to a family of dyes which fluoresce in the UV-VIS, far red and near infrared wavelengths of the spectrum and possess asymmetric lipophilic alkyl chains. The dyes of the invention are soluble in commercially available membrane staining dyes, are useful as probes for rapidly staining lipophilic structures such as membranes in cells or isolated from cells, and are well-retained therein. Methods of utilizing the dyes to detect stained cells both in vivo and in vitro are also disclosed.Type: ApplicationFiled: November 17, 2006Publication date: December 10, 2009Applicant: Phanos Technologies, Inc.Inventor: Brian D.
