The present invention relates to novel tricyclic agonist derivatives of cholinergic receptors. These compounds correspond to the formula in which: - X represents a group (CH 2 ) n with n representing an integer equal to 2, 3 or 4 or also a vinylene group or a methyl vinylene group; - R, and R 2 considered independently represent hydrogen or a substituent occupying one of the free positions of the benzene cylce and chosen from halogens, a lower alkyl group, a lower alkoxy group, a hydroxy group, a thiol group, a nitro group, an optionally substituted amino group; - Y represents oxygen, sulfur or a group -NH-; - R 3 represents in particular an amino group. |
