Synthesis of water-soluble first generation janus-type dendrimers bearing Asp oligopeptides and naproxen

Abstract

To construct a water-soluble and bone-targeting non-steroidal anti-inflammatory dendritic drug carrier, a series of Asp oligopeptides and naproxen based poly amido-ester Janus dendrimers were synthesized using a conventional method and their water solubility was preliminary evaluated. The corresponding small dendritic linkers contain two or three drug moieties on the surface and two or three oligopeptides groups at the focal terminus. This design provided an effective entry for the synthesis of multiple drug carriers with water-soluble and bone-targeting.
