CONFORMATIONALLY RESTRAINED BETA-BLOCKING OXIME ETHERS .3. SYNTHESIS AND BETA-ADRENERGIC ANTAGONISTIC ACTIVITY OF DIASTEREOMERIC ANTI AND SYN 5'-(3'-METHYL)ISOXAZOLIDINYL)-N-ALKYLETHANOLAMINES
Mc. Breschi et al., CONFORMATIONALLY RESTRAINED BETA-BLOCKING OXIME ETHERS .3. SYNTHESIS AND BETA-ADRENERGIC ANTAGONISTIC ACTIVITY OF DIASTEREOMERIC ANTI AND SYN 5'-(3'-METHYL)ISOXAZOLIDINYL)-N-ALKYLETHANOLAMINES, European journal of medicinal chemistry, 31(2), 1996, pp. 159-163
The diastereomeric anti (1d, 2d) and syn (3d, 4d) 5'-(3'-methyl)isoxaz
olidinyl)-N-alkylethanolamines were synthesized and assayed for their
beta(1)- and beta(2)-adrenergic antagonistic activity by functional te
sts on isolated preparations. The pharmacological results, which were
compared with those previously obtained for the corresponding isoxazol
ine analogs (1d-4d) substituted in the 3'-position with an isopropyl g
roup instead of the methyl group in 1d-4d, indicateci that the beta-ad
renergic antagonistic activity of the 3'-alkyl-substituted compounds 1
-4 is not substantially influenced by the size of the alkyl substituen
t.
