The present invention provides novel fluorescent compounds and covalent attachment chemistries which facilitate the use of these compounds as labels for ultrasensitive and quantitative fluorescent detection of low levels of biomolecules. In a preferred embodiment, the fluorescent labels of this invention are novel derivatives of the hydroxy-pyrene trisulphonic and disulphonic acids which may be used in any assay in which radioisotopes, colored dyes or other fluorescent molecules are currently used. Thus, for example, any assay using labeled antibodies, proteins, oligonucleotides or lipids, including fluorescent cell sorting, fluorescence microscopy (including dark-field microscopy), fluorescence polarization assays, ligand, receptor binding assays, receptor activation assays and diagnostic assays can benefit from use of the compounds disclosed herein.
摘要:
The present invention relates to trimesic acid amides, pharmaceutical compositions comprising said compounds, uses of said compounds and compositions, and processes for their preparation. Specifically, this invention relates to means to enhance insulin-dependent glucose uptake. More specifically, the invention concerns compounds and pharmaceutical compositions that active the insulin receptor kinase, which leads to an increased sensitivity to insulin and an increase in glucose uptake, as well as processes for preparation of the compounds. As such, the invention also concerns methods or uses of the compounds for the treatment of animals with hyperglycemia, especially for the treatment of type 2 diabetes.
摘要:
The invention relates to a method for treating solvent-spun cellulose fibers during which the fibers are brought into contact with a textile auxiliary in an alkaline medium. The inventive method is characterized in that a compound of general formula (I) or a salt thereof is used as the textile auxiliary, whereby: R1 is a binding link selected from the group consisting of a linear or branched chain with 1 to 4 C atoms and phenyl; R2 and R3 are identical or different from one another and are selected from the group consisting of (CH2)m-CH=CH2 with m ranging from 0 to 2, and; R4 represents an ionic group and/or a group that can be ionized in the alkaline medium.
摘要:
The present invention relates to a method for the treatment of a disorder or disease of a living animal body, including a human, which disorder or disease is responsive to the blockade of chloride channels, comprising administering to a living animal body in need thereof a therapeutically effective amount of a compound having formula (I) or a pharmaceutically acceptable salt thereof wherein R?2, R3, R4 and R5¿ are each independently selected from hydrogen, alkyl, cycloalkyl, cycloalkylalkyl, alkenyl, alkynyl, alkoxy, hydroxy, halogen, trifluoromethyl, trifluoromethoxy, cyano, nitro, amino, and aryl, aralkyl, arylamino, aryloxy, aryl-CO-, or heteroaryl, wherein the aryl or heteroaryl group may be substituted one or more times with substituents selected from alkyl, cycloalkyl, cycloalkylalkyl, alkenyl, alkynyl, hydroxy, alkoxy, halogen, trifluoromethyl, trifluoromethoxy, cyano, nitro and amino; or R?3 and R4 or R4 and R5¿ together form a fused 4 to 7 membered carbocyclic ring which may be unsaturated, or partially or fully saturated while the other substituents R?2, R3, R4 and R5¿ is as defined above; Y is -CO-, -CS-, -SO¿2?-, or -C(=N-R?8¿)-, wherein R8 is hydrogen, alkyl, or cyano; X is -NH-, -CH¿2?-NH-, -SO2-NH-, or -CH2-; Z is -NR?6¿-, -O-, -CH=CH-, -N=CH-, -CH=N-, or -NR6-CH2-, wherein R6 is hydrogen, or alkyl; R?11, R12, R13, R14 and R15¿ are each independently selected from hydrogen, alkyl, cycloalkyl, cycloalkylalkyl, alkenyl, alkynyl, alkoxy, hydroxy, halogen, trifluoromethyl, trifluoromethoxy, cyano, nitro, amino, and aryl, aralkyl, arylamino, aryloxy, aryl-CO-, or heteroaryl, wherein the aryl or heteroaryl group may be substituted one or more times with substituents selected from alkyl, cycloalkyl, cycloalkylalkyl, alkenyl, alkynyl, hydroxy, alkoxy, halogen, trifluoromethyl, trifluoromethoxy, cyano, nitro and amino; or one of R?11 and R12, R12 and R13, R13 and R14 or R14 and R15¿ together form a fused 4 to 7 membered carbocyclic ring which may be unsaturated, or partially or fully saturated while the other substituents R?11, R12, R13, R14 and R15¿ is as defined above.
