Twonovel chlorinated fluoresceins 2′,4′,5′,7′-tetrachloro-6-(5-carboxypentyl)-4,7-dichloro fluorescein succinimidyl ester (1G) and 2′,4′,5′,7′-tetrachloro-6-(3-carboxypropyl)-4,7-dichlorofluorescein succinimidyl ester (2G) were synthesized as fluorescent probes for labeling proteins. Structures of target compounds and intermediates were determined via IR, MS, 1H NMR and element analysis. The investigation

Disclosed herein are novel quinone methide analog precursors and embodiments of a method and a kit of using the same for detecting one or more targets in a biological sample. The method of detection comprises contacting the sample with a detection probe, then contacting the sample with a labeling conjugate that comprises an enzyme. The enzyme interacts with a quinone methide analog precursor comprising a detectable label, forming a reactive quinone methide analog, which binds to the biological sample proximally to or directly on the target. The detectable label is then detected. In some embodiments, multiple targets can be detected by multiple quinone methide analog precursors interacting with different enzymes without the need for an enzyme deactivation step.
This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as proteins and protein fragments from biological samples from in vivo and in vitro sources. Agents comprise a detectable group bound to a photoreactive group. Conjugates comprise agents coupled to substrates by covalent bounds which can be selectively cleaved with the administration of electromagnetic radiation. Targets substances labeled with detectable molecules can be easily identified and separated from a heterologous mixture of substances. Exposure of the conjugate to radiation releases the target in a functional form and completely unaltered. Using photocleavable molecular precursors as the conjugates, label can be incorporated into macromolecules, the nascent macromolecules isolated and the label completely removed. The invention also relates to targets isolated with these conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals.

The present invention relates compounds and compositions for interfering with the association of Myc and Max. These compounds and compositions are useful in methods for inhibiting growth or proliferation of a cell. Methods of inhibiting growth or proliferation of a cell comprise contacting the cell with an amount of a compound that interferes with Myc and Max association effective to inhibit growth or proliferation of the cell. The compounds exhibit increased inhibitory activity against c-Myc relative to the known c-Myc inhibitor small-molecule benzofurazan N-([1,1′-biphenyl]-2-yl)-7-nitrobenzo[c][1,2,5]oxadiazol-4-amine (10074-G5).
