Synthesis, antiarrhythmic and hypotensive activity of some novel 1,3-disubstituted ureas and phenyl N-substituted carbamates
摘要:
Some new 1,3-disubstituted ureas and phenyl N-substituted carbamates were prepared and evaluated in vivo for their antiarrhythmic and hypotensive properties. The compound 1-tert.-butyl-1-(3-cyclopentyloxy-2-hydroxypropyl)-3-methylurea 2c exhibited a strong hypotensive action. The compounds 2-(l-tert.-butyl-3-methylureido)-1-(cyclopentyloxymethyl)ethyl N-isopropylcarbamate 3c and 2-(l-tert.-butyl-3-ethylureido)-1-(cyclopentyloxymethyl)N-isopropylcarbamate 3f showed an antiarrhythmic activity comparable to that of the reference drug Propranolol.

Ether Derivatives of 3-Amino-1,2-propanediols, V. Syntheses and Pharmacological Activities of 5-(Cycloalkoxymethyl)oxazolidines andN–Substituted Derivatives
derivatives 3a–j were synthesized by reaction of the aminopropanols 4a, b and 2a–j with formaldehyde. Some of the compounds were found to have moderate β‐blocking activity and 3b and 3h were found to have considerable antiarrhythmic activity.
