the 3‐amino‐1‐propanol moiety common to the many previously described non‐imidazole H3 ligands. Detailed structure‐activity studies revealed that 1‐(2‐benzofuranylmethyl)‐ 5c (pA2 = 8.47 ± 0.05) and 1‐(3‐benzofuranylmethyl)‐4‐[5‐(N‐methyl‐N‐propyl)pentyloxy]piperidine 5d (pA2 = 8.15 ± 0.07) exhibit high potency for the H3 histamine receptor. In addition, the potency of selected 1‐[(N‐substituted‐N‐

The present invention relates to new 4,5,7,8-tetrahydro-6H-thiazolo[5,4-d]azepines of general formula II ##STR1## wherein the substituents are defined herein below, which compounds have valuable pharmacological properties, namely selective effects on the dopaminergic system which are achieved by stimulating (predominantly D2) dopamine receptors.
Benzocondensed derivatives as rigid analogues of the μ-opioid agonist 3(8)-cinnamyl-8(3)-propionyl-3,8-diazabicyclo[3.2.1]octanes: synthesis, modeling, and affinity
A new series of rigid analogues (1a-g, 2a-g) of the previously reported analgesic 3-cinnamyl-8-propionyl-3,8-diazabicyclo[3.2.1]octane (I) and its reverted isomer 3-propionyl-8-cinnamyl (II) were synthesized, in which the cinnamyl substituent is incorporated in benzocondensed bicyclic systems. Binding assays for the affinity towards mu receptors indicated that, while in the reverted series 2 the beta-naphthylmethyl (2d) and the benzocycloheptenylmethyl derivative (2g) favorably compared with II, all compounds 1 displayed a mu-affinity lower than that of the parent I. Modeling studies suggest that the flexibility of the cinnamyl side chain plays an important role for activity. (C) 1998 Elsevier Science S.A. All rights reserved.
