We previously found that N-(4-aminophenyl)-4-trifluoromethylbenzamide (TFAP), a COX-1 inhibitor, exhibits an analgesic effect without causing gastric damage. Unfortunately, TFAP causes reddish purple coloration of urine, and its analgesic effect is less potent than that of indomethacin. Herein we describe our study focusing on the development of 4- and 5-amino-2-alkoxy-N-phenylbenzamide scaffolds, designed on the basis of the structures of TFAP and parsalmide, another known COX-1 inhibitory analgesic agent. 5-Amino-2-ethoxy-N-(2- or 3-substituted phenyl)benzamide derivatives exhibited analgesic activity in a murine acetic acid induced writhing test. Among these compounds, 5-amino-2-ethoxy-N-(2-methoxyphenyl)benzamide (9v) possesses potent COX-1 inhibitory and analgesic activities, similar to those of indomethacin. In addition, 5-amino-2-ethoxy-N-(3-trifluoromethylphenyl)benzamide (9g) showed a more potent analgesic effect than indomethacin or 9v without causing apparent gastric damage or coloration of urine, although its COX-1 inhibitory activity was weaker than that of indomethacin or 9v. Thus, 9g and 9v appear to be promising candidates for analgesic agents and are attractive lead compounds for further development of COX-1 inhibitors.
