Abstract

Two series of analogues of 9-propionyl-10-cinnamyl-9,10-diazatricyclo[4.2.1.1(2,5)]decane (1a) and 2-propionyl-7-cinnamyl-2,7-diazatricyclo[4.4.0.0(3,8)]decane (2a), in which the cinnamyl moiety was replaced by various aralkenyl chains, 1b-1 and 2b-1, respectively, have been synthesized and evaluated for their ability to bind to the opioid mu-, delta- and kappa-receptors. The binding data indicated that compounds 1b,d,e,h and 2b,d,e,f,h,i showed a mu-affinity in the low nanomolar range with moderate or negligible affinity towards delta- and kappa-receptors. Selected DTDs, the pairs 1,2b,1,2e and 1,2h, were also evaluated for analgesic effect. In the hot plate test, only 1b given ip was found to have similar opioid antinociception and chronic tolerance as morphine. (C) 2003 Elsevier Ltd. All rights reserved.
