BioAssay: AID 180157

Effective dose was measured by using rat tail flick assay after subcutaneous administration

A series of 8-alkyl-3-methoxy-17-methylmorphinan-6-ones (3C) and -isomorphinan-6-ones (3T) were prepared by conjugate addition of lithium dialkylcuprates to the corresponding 7,8-didehydro-6-ones 2C and 2T. These 17-methyl compounds were potent analgesics and were converted to mixed narcotic agonists-antagonists 7-10, by replacement of the 17-methyl groups with cycloalkylmethyl moieties. The 8 more ..

Title: Analgesic narcotic antagonists. 2. 8-Alkymorphinan-6-ones.

Abstract: A series of 8-alkyl-3-methoxy-17-methylmorphinan-6-ones (3C) and -isomorphinan-6-ones (3T) were prepared by conjugate addition of lithium dialkylcuprates to the corresponding 7,8-didehydro-6-ones 2C and 2T. These 17-methyl compounds were potent analgesics and were converted to mixed narcotic agonists-antagonists 7-10, by replacement of the 17-methyl groups with cycloalkylmethyl moieties. The 8 substituent modified the type of activity observed. One of these compounds, 17-(cyclobutylmethyl)-3-hydroxy-8 beta-methylmorphinan-6-one (10Ca), had an agonist-antagonist ratio of 0.1. Compound 10Ca did not support or cause dependence in rats. This compound, however, appeared to be a typical narcotic agent in morphine-dependent monkeys.
