Abstract
A simple strategy for designing salt-based supramolecular gelators comprised of various nonsteroidal anti-inflammatory drugs (NSAIDs) and amantadine (AMN) (an antiviral drug) has been demonstrated using a supramolecular synthon approach. Single-crystal and powder X-ray diffraction established the existence of the well-studied gel-forming 1D supramolecular synthon, namely, primary ammonium monocarboxylate (PAM) synthon in all the salts. Remarkably five out of six salts were found to be capable of gelling methyl salicylate (MS)-an important ingredient in commercially available topical gels; one such selected biocompatible salt displayed an anti-inflammatory response in prostaglandin E2 (PGE2 ) assay, thereby indicating their plausible biomedical applications.
