摘要:
##STR1## A bisheterocyclic compound represented by general formula (I), stereoisomers thereof, tautomers thereof, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, a pharmaceutical composition containing the same, and a process for the production thereof. In formula (I), R 1 and R 2 may be the same or different from each other and each represents (II) or (III), R 3 represents hydrogen or a protective group, X, Y 1 and Y 2 may be the same or different from one another and each represents oxygen or sulfur, B 1 and B 2 represent each phenylene, B 3 represents phenylene, naphthylene, cyclohexylene or furo[3,2-b]furanylene, L 1 and L 2 represent each --(O) n --A--, n represents 0 or 1, and A represents a single bond or lower alkylene, provided that when n is 1, A represents alkylene and the oxygen atom of each of L 1 and L 2 is bonded to B 3 . The above compounds are useful as a hypoglycemic drug based on the activity of enhancing insulin sensitivity.

摘要:
Phenethylamine derivatives shown by the general formula ##STR1## wherein Ro represents a lower alkyl group; R.sub.1 represents a lower alkyl group or a lower alkoxy group; R.sub.2 represents hydrogen atom or a hydroxyl group; R.sub.3 and R.sub.4 each represents hydrogen atom or a lower alkyl group; R.sub.5 represents hydrogen atom or a lower alkoxy group; X represents oxygen atom or a methylene group; m is an integer of 1-3; and n is an integer of 0-2 and the acid addition salts thereof.These compounds exhibit a strong .alpha.-adrenergic blocking action and are useful as an antihypertensive agent.
摘要:
Novel sulfamoyl-substituted phenethylamine derivatives which exhibit .alpha.-adrenergic blocking action and are useful as an antihypertensive agent and an agent for the treatment of congestive heart failure.
摘要:
Pharmaceutical compositions are provided for the treatment of disorders in a subject, such as hypertension, congestive heart failure, angina pectoris, lower urinary tract dysfunction and prostatic hypertrophy. The compositions when administered to a subject produce an .alpha.-adrenergic blocking action and contain as an active ingredient sulfamoyl-substituted phenethylamine derivatives, such as optically active 5-2-[ 2-(2-ethoxyphenoxy)ethylamino] -2-methylethyl-2-methoxybenzenesulfonamide 2-methoxybenzenesulfonamide, and a pharmaceutically acceptable carrier.
