As systemically used therapeutics for treatmenting acute or chronic pains or inflammations, non-steroidal anti-inflammatory drugs (NSAID) 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., an NSAID) not only affords supramolecular hydrogelators for the topical gels, but also unexpectedly and significantly elevates the selectivity towards COX-2 about 20 times 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.
