Abstract: Parsalmide (5-amino-N-butyl-2-(2-propynyloxy) benzamide) (5a), is a non-steroidal anti-inflammatory drug (NSAID), commercialised in Italy until 1985 with the brand name of Synovial(R), that has been widely used to treat arthritic patient. In addition, it was shown to spare gastric mucosa. Here we have synthesised a series of novel substituted benzamides, related to Parsalmide, and have evaluated their activity in vitro on COX-1 and COX-2 as well as in vivo in the carrageenin-induced rat paw edema, a classical in vivo anti-inflammatory assay. Compounds 5b, 11a and 11b, which showed a favourable profile in vitro and in vivo, were screened in comparison with Parsalmide for gastrointestinal (GI) tolerability in vivo in the rat. Results obtained showed that Parsalmide and compound 11b inhibited both COX-1 and COX-2 in vitro as well as they were active in vivo. Both compounds were devoid of gastric effect at the efficacious dose. In addition, both prevented indomethacin-induced gastric damage. Thus, these compounds may guide the definition of a new leading structure with anti-inflammatory activity that may allow designing new safer NSAIDs.
