Patent number: 6562632Abstract: The invention describes reactive dyes having an alkyl spacer attached via a sulfonamide bond to a sulforhodamine 101 fluorophore, and a variety of useful conjugates prepared therefrom. The increased length of the covalent linkage due to the alkyl spacer results in dye-conjugates having a number of surprisingly advantageous properties relative to previous sulforhodamine 101-labeled conjugates, including enhanced solubility and increased fluorescence. The reactive dyes of the present invention are more stable than the known compound sulforhodamine 101 sulfonyl chloride. Novel reactive dyes are described for selective modification of groups other than amines, including thiols and photoreactive derivatives.Type: GrantFiled: August 4, 1998Date of Patent: May 13, 2003Assignee: Molecular Probes, Inc.Inventors: Wojciech Szalecki, Richard P.

Patent number: 6559306Abstract: This invention relates to new fluorescent or non-fluorescent dye compounds having a terminal hydroxy, carboxylic acid/ester or amino group and a process for their preparation. The new fluorescent or non-fluorescent dye compounds are useful as colorants for preparing colored synthetic polymer resins with pigmentary properties, for dyeing or printing homo- or mixed synthetic, semi-synthetic or natural polymers or substrates or for preparing inks. The dye compounds provide excellent properties, especially high temperature stability and easy applicability.Type: GrantFiled: July 13, 2001Date of Patent: May 6, 2003Assignee: Clariant Finance (BVI) LimitedInventors: Bansi Lal Kaul, Jean-Christophe Graciet

Publication number: 20030040525Abstract: Certain non-nucleoside compounds that will selectively inhibit telomerase by targeting the nucleic add structures, such as G-quadruplexes, that may be associated with human telomeres or telomerase have been identified. Inhibition of human telomerase by two perylenetetracarboxylic acid diimides and a carbocyanine has been demonstrated. 1H-NMR studies have evidenced the stabilization of a G-quadruplex by the perylenetetracarboxylic acid diimide compounds and provided evidence that these and structurally related compounds inhibit the telomerase enzyme by a mechanism consistent with interaction with G-quadruplex structures.Type: ApplicationFiled: August 27, 2001Publication date: February 27, 2003Applicant: Board of Regents, The University of Texas SystemInventors: Sean M.
