title: Synthesis and analgesic activity of N-substituted 6,7-benzomorphans.
abstract: Some new N-substituted 6,7-benzomorphans were prepared and tested for analgetic activity. The compounds (I) and (II), which proved the most active in a preliminary screening, were submitted to a more detailed investigation, and their ED50 was determined in mice by the phenylquinone, hot-plate and tail-pinch tests. Studies of acute toxicity and physical dependence capacity were also performed.
