Two subseries of nonquaternized (5a-10a) and quaternized derivatives (5b-10b) related to oxotremorine and oxotremorine-M were synthesized and tested. The agonist potency at the muscarinic receptor subtypes of the new compounds was estimated in three classical in vitro functional assays: M1 rabbit vas deferens, M2 guinea pig left atrium and M3 guinea pig ileum. In addition, the occurrence of central

This invention relates to compounds having activity as muscarinic M1 or M1 and M4 receptor agonists which are useful in the treatment of diseases mediated by the muscarinic M1 and M4 receptors. Also provided are pharmaceutical compositions containing the compounds and the therapeutic uses of the compounds. Compounds provided are of formula (I) where X1; X2; X3; X4; Y; Z; n, R1 and R2 are defined herein.
Aryl and alkyl substituted 3- and 5-nitroisoxazole derivatives were prepared from the appropriate 3- and 5-nitro-4,5-dihydroisoxazoles using manganese(IV) oxide as oxidizing agent. Some of the 3-nitro-4-substituted isoxazoles were prepared directly by reaction of 2-substituted 3-bromo-l-halopropanes with sodium nitrite.
acetylcholine receptors, was limited because the synthesis of its precursor, the iperoxo base, was characterized by low yields, laborious chromatography and low reproducibility. Here we report a robust convergent three-step synthesis by means of a Mannichreaction and nucleophilic substitution at the 3-nitro-Δ2-isoxazoline. The newroute combines short reaction time, high reproducibility and an overall yield

The synthesis and radioligand binding assays of a group of muscarinic ligands related to oxotremorine are reported. The new compounds displayed binding affinities comparable to those of the parent molecule with the exception of the trimethylammonium salt 6, which behaved as a fill muscarinic agonist and showed a pronounced selectivity for M-2 versus M-1 muscarinic receptor subtypes.
