PubMed Abstract: Vitamin A derived retinoid compounds have multiple, powerful roles in the cellular growth and development cycle and, as a result, have attracted significant attention from both academic and pharmaceutical research in developing and characterizing synthetic retinoid analogues. Simplifying the hit development workflow for retinoid signaling will improve options available for tackling related pathologies, including tumor growth and neurodegeneration. Here, we present a novel assay that employs an intrinsically fluorescent synthetic retinoid, DC271, which allows direct measurement of the binding of nonlabeled compounds to relevant proteins. The method allows for straightforward initial measurement of binding using existing compound libraries and is followed by calculation of binding constants using a dilution series of plausible hits. The ease of use, high throughput format, and measurement of both qualitative and quantitative binding offer a new direction for retinoid-related pharmacological development.
