Derivatized biotin compounds and methods of use

摘要

An efficient synthesis for the selective and efficient 1'-N derivatization of biotin is reported. The derivatized biotin acts as a stable analog of the carboxyphosphate intermediate in naturally-occurring biotin-mediated CO2 transfer. The synthesis may readily be scaled up to perform large-scale, selective acylations of biotin. The stable analog of the intermediate can inhibit the activity of the biotin carboxylase enzymes such as acetyl CoA carboxylase, and HIV protease. The functionalization at the 1'-N of biotin results in the attachment of an electrophilic "handle" amenable to reaction with a wide variety of nucleophiles to generate a new family of biotin analogs.
