摘要:The Synthesis And Alpha-Adrenergic Activity Of A Series Of Substituted 2-Imidazolinylindolines Are Described. Substitution In The Indoline Ring Generated Compounds With A Spectrum Of Adrenoceptor Antagonist/agonist Profiles That Proved Sensitive To Both The Nature And Position Of The Substituent. Many Of The Derivatives Possess Greater Presynaptic Antagonist Potency Than The Corresponding Benzodioxan 1,Dihydrobenzofuran 2,And Indan 3 Analogues; However,This Alpha 2-Antagonism Is Often Accompanied By Alpha 1-Agonist Activity. It Was Not Possible To Separate Alpha 2-Antagonist From Alpha 1-Agonist Properties In This Series. Compounds Of Most Interest Proved To Be The N-Ethyl 6,5-Chloro-N-Methyl 18,And 5-Chloro-N-Ethyl 23 Derivatives,All Being Potent Alpha 2-Antagonists And Alpha 1-Agonists. Substitution At The 4-And 7-Position Of The Indoline Ring Generally Gave Compounds With Nonselective Agonist Properties.
