    摘要: Coumpounds having adrenergic activity which are selective agonists for one or both of the α2B and α2C adrenoceptor receptor subtypes in preference to the α2A adrenoceptor receptor subtype; the active compound being selected from the group consisting of compounds having formula (I) wherein the dotted lines represent optional bonds provided that two double bonds may not share a common carbon atom; R is H or lower alkyl; X is S or C(H)R1, wherein R1 is H or lower alkyl, but R1 is absent when the bond between X and the ring represented by formula (a) is a double bond; Y is O, N, S, (CR12)y, wherein y is an integer of from 1 to 3, -CH=CH- or -Y1CH2-, wherein Y1 is O, N or S; x is an integer of 1 or 2, wherein x is 1 when R?2, R3 or R4¿ is bound to a saturated carbon atom and x is 2 when R?2, R3 or R4¿ is bound to a saturated carbon atom; R2 is H, lower alkyl, halogen, hydroxy or lower alkoxy, or, when attached to a saturated carbon atom, R¿2? may be oxo; R3 and R4 are, each, H, lower alkyl, hydroxy, lower alkoxy, or phenyl or, together, are -(C(R?2¿)x)z-; -Y1(C(R2)x)z'-; -Y?1(C(R2)x)yY1¿-; -(C(R?2)x)-Y1-(C(R2¿)x)-; -(C(R?2)x)-Y1-(C(R2¿)x)-(C(R2)x)- and -Y?1-(C(R2)x)-Y1-(C(R2¿)x)- wherein z is an integer of from 3 to 5, z' is an integer of from 2 to 4 and x and y are as defined above, and further either end of each of these divalent moieties may attach at either R3 or R4 to form a condensed ring structure and the rings formed may be totally unsaturated, partially unsaturated, or totally saturated; and being useful for treating muscle spasticity including hyperactive micturition, diarrhea, diuresis, withdrawal syndromes, pain including neuropathic pain, neurodegenerative diseases, memory and cognition deficits, psychoses including manic disorders and anxiety, hypertension, cardiac ischemia, congestive heart failure, and nasal congestion without sedating or cardiovascular side effects.
