Adrenergic sulfonanilides. 4. Centrally active .beta.-adrenergic agonists

Abstract
The CNS activities of a number of soterenol analogues were investigated [in the rat]. Several of these compounds possessed potent morphine antagonistic and anorexiant properties. The CNS activity of these compounds was enhanced by certain lipophilic [e.g., 1,1-dimethyl-2-phenethyl or cyclopropyl] N substituents; minor structural changes on either the aromatic or side-chain moieties drastically reduced central activity. Toxicity in this series was related to the inherent .alpha.-adrenergic stimulating component (direct or indirect).
