  d-Amino Acids Boost the Selectivity and Confer Supramolecular Hydrogels of a Nonsteroidal Anti-Inflammatory Drug (NSAID)

  摘要：

  As systemically used therapeutics for treating acute or chronic pains or inflammations, nonsteroidal anti-inflammatory drugs (NSAIDs) also associate with the adverse gastrointestinal and renal effects and cardiovascular risks. Thus, it is beneficial to develop topical gels that selectively inhibit cyclooxygenase-2 (COX-2) for the management of local inflammation. In this work, we demonstrate that the covalent conjugation of D-amino acids to naproxen (i.e., a NSAID) not only affords supramolecular hydrogelators for the topical gels but also unexpectedly and significantly elevates the selectivity toward COX-2 about 20X at little expense of the activity of naproxen. This work illustrates a previously unexplored approach that employs D-amino acids for the development of functional molecules that have dual or multiple roles and exceptional biostability, which offers a new class of molecular hydrogels of therapeutic agents.

  Described herein are compounds comprising an oligopeptide and a non-steroidal antiinflammatory agent. The compounds self-assemble into supramolecular hydrogels and can be used as topical treatments for inflammatory conditions, such as osteoarthritis. Also described herein are oligopeptides compounds made from D-amino acid residues that form supramolecular hydrogels. The compounds may be functionalized with active agents, such as anticancer therapeutic agents, antiinflammatory agents, or imaging agents, therefore providing new mechanisms for delivery of active agents.
