摘要:
7-[2-Dialkylamino)ethyl]-4-hydroxy-1,3-benzimidazol-2-ones are prepared by oxidative cyclization of a urea, followed by removal of protective groups. The compounds are D.sub.2 -agonists and, thereby, have anti-hypertensive activity. A species of the group is 7[2-N,N-di-n-propylamino)ethyl]-4-hydroxyl-1,3-benzimidazol-2-one.
摘要:
Certain aminoethyl substituted 1,3-benzthiazol- and 1,3-benzoxazol-2(3H)-ones are D.sub.2 -dopamine agonists. These compounds are prepared by reacting an appropriate o-aminophenol or thiophenol with phosgene.

摘要:
Certain 2-amino-6-.omega.-aminoethylphenols and thiophenols are intermediates for preparing D.sub.2 -dopamine agonistic aminoethyl substituted 1,3-benzthiazol- and 1,3-benzoxazol-2(3H)-ones.
摘要:
An oral antiplaque composition for treatment of teeth wherein the essential antiplaque agent is a substantially water insoluble noncationic antibacterial phenol containing, relative to the hydroxyl group, an alkyl or cycloalkyl group, preferably tert.-butyl (t-butyl), in the 2-position, and substituents in one or both of the 4- and 5-positions, one or both of which may be alkyl or cycloalkyl, one being preferably t-butyl.
摘要:
A pumpable, fluid composition of amine oxide, betaine and/or sultaine is prepared with active concentration of about 36-45% of these materials by the addition of alkaline earth or aluminum salts.
