A series of substituted N-cycloalkyl benzamides, cinnamamides, and indole-3-carboxamides were synthesized and evaluated for their analgesic, antiinflammatory activities as well as for their gastrointestinal irritation liability. Indomethacin was used as reference drug in both tests: Compounds 1k, 1b, 1h, 1j, and 1g were the most active in the antiinflammatory paw edema inhibition test, with a sharply dose-dependent effect. In terms of the analgesic activity (acetic acid writhing test), the most active compound was 5a followed by 3a, but many other compounds were found to have a non- negligible potency. Even in this case, the effect was dose dependent.
