ABSTRACT:

TECHNICAL FIELD
This invention relates to new propanolamine derivatives which is the &bgr;
3
adrenergic receptor agonist and salts thereof which are useful as a medicament.
DISCLOSURE OF INVENTION
This invention relates to new propanolamine derivatives which is the &bgr;
3
adrenergic receptor agonist and salts thereof.
More particularly, it relates to new propanolamine derivatives and salts thereof which have gut selective sympathomimetic, anti-ulcerous, anti-pancreatitis, lipolytic, anti-urinary incontinence and anti-pollakiuria activities, to processes for the preparation thereof, to a pharmaceutical composition comprising the same and to a method of using the same therapeutically in the treatment and/or prevention of gastro-intestinal disorders caused by smooth muscle contractions in human beings or animals, and more particularly to a method for the treatment and/or prevention of spasm or hyperanakinesia in case of irritable bowel syndrome, gastritis, gastric ulcer, duodenal ulcer, enteritis, cholecystopathy, cholangitis, urinary calculus and the like; for the treatment and/or prevention of ulcer such as gastric ulcer, duodenal ulcer, peptic ulcer, ulcer caused by non steroidal anti-inflammatory drugs, or the like; for the treatment and/or prevention of dysuria such as pollakiuria, urinary incontinence or the like in case of nervous pollakiuria, neurogenic bladder dysfunction, nocturia, unstable bladder, cystospasm, chronic cystitis, chronic prostatitis, overflow incontinence, passive incontinence, reflux incontinence, urge incontinence, urinary stress incontinence or the like; and for the treatment and/or prevention of pancreatitis, obesity, diabetes, glycosuria, hyperlipidemia, hypertension, atherosclerosis, glaucoma, melancholia, depression and the like.
One object of this invention is to provide new and useful propanolamine derivatives and salts thereof which have gut selective sympathomimetic, anti-ulcerous, lipolytic, anti-urinary incontinence and anti-pollakiuria activities.
Another object of this invention is to provide processes for the preparation of said propanolamine derivatives and salts thereof.
A further object of this invention is to provide a pharmaceutical composition comprising, as an active ingredient, said propanolamine derivatives and salts thereof.
Still further object of this invention is to provide a therapeutical method for the treatment and/or prevention of aforesaid diseases in human beings or animals, using said propanolamine derivatives and salts thereof.
The object propanolamine derivatives of this invention are new and can be represented by the following general formula [I]:

In the above and subsequent description of the present specification, suitable examples of the various definition to be included within the scope of the invention are explained in detail in the following.
The term “lower” is intended to mean a group having 1 to 6 carbon atom(s), unless otherwise provided.
The preferable number of the “one or more” in the term of “one or more suitable substituent(s)” may be 1 to 4.
Suitable example of “halogen” may be fluoro, chloro, bromo, iodo, and the like.
Suitable example of “lower alkyl” may include straight or branched one having 1 to 6 carbon atom(s), such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-butyl, pentyl, 1-methylpentyl, tert-pentyl, neo-pentyl, hexyl, isohexyl and the like.
Suitable example of “higher alkyl” may include straight or branched one having 7 to 20 carbon atoms, such as heptyl, octyl, 3,5-dimethyloctyl, 3,7-dimethyloctyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, icosyl, and the like.
