Application of Monodisperse PEGs in Pharmaceutics: Monodisperse Polidocanols
摘要:
Polydisperse PEGs are ubiquitously used in pharmaceutical industry and biomedical research. However, the monodispersity in PEGs may play a role in the development of safe and effective PEGylated small molecular drugs. Here, to avoid the polydispersity in polidocanol, the active ingredient in a clinically used drug, a macro cyclic sulfate-based strategy for the efficient and scalable synthesis of monodisperse polidocanols, their sulfates, and their methylated derivatives, was developed. TLC and HPLC analysis indicated a complex mixture in regular polidocanol and high purifies in monodisperse polidocanols and their derivatives. Assay on HUVEC, L929, and HePG2. cells showed-that monodisperse polidocanols have much higher cytotoxicity and safety than that of regular polidocanol. It was found that the monodispersity of PEGs in polidocanols is crucial for achieving the optimal therapeutic results. Therefore, based on this case study, it would be beneficial to optimize PEGylated small molecular drugs with monodisperse PEGs in pharmaceutical research and development.
