Hydroxyl substituents caused no great loss of activity, but alkoxy and amino substituents did. Arylalkylamino groups, particularly those with an alkyl rx substituent, were very active, which suggested significant receptor interaction. , 1976). , 1977), and the acylaminoalkylamines (95) (SMITH, 1974, 1976a, b). The dimethoxyphenylethyl side chain ofCI-775 appeared to confer greater CH 3 ~1I'b:CII'NHCH,cII,o-O-CONII' (93) ~ OCH2CHCH2NHCH2CH2NHR oI OH (95) (94) R = -COR', -CONHR', -S02NHR' cardioselectivity to a number of antagonists when it was substituted for isopropyl.
On the basis of their pharmacological findings and the results of nuclear magnetic resonance spectroscopic studies, JEN and KAISER (1977) proposed that the side chains of the protonated species of aryloxypropanolamines in chloroform solution existed in a bicyclic "rigid" conformation (63) involving two intramolecular hydrogen bonds. , 1968); and the methylene (HOWE, 1970) isosteric analogs of propranolol. , 1975), which are capable of double intramolecular hydrogen bonding, have significant adrenergic activity.
The tert-butyl-amino analog (C-78) (39 a) of clorprenaline, was reported to be orally active and more potent. , 1975). K. , 1977). These metabolites may participate in the activity and duration of the action of C-78.
