摘要:
4-Alkyl-5,6-, 6,7-methylenedioxy-2-1[H]-quinazolinones are prepared from 2,3-methylenedioxyacetophenones. The 4-alkyl-5,6-, 6,7-methylenedioxy-2-1[H]-quinazolinones are active as cardiotonic agents.
摘要:
Novel 2,2,4-trialkyl-1,2-dihydroquinazoline-3-oxides and their synthesis are described. These compounds possess cardiotonic activity, and are useful for the treatment of heart failure.
摘要:
Novel 6,7-dimethoxy-1,2-dihydro-2-arylquinazoline-3-oxides and their synthesis are described. These novel compounds are cardiotonic agents and bronchodilating agents, and as such are useful for the treatment of heart failure and asthma.

摘要:
Novel substituted quinazoline-3-oxides are disclosed as are methods of increasing cardiotonic activity and bronchodilation in which an unit dose of a composition containing an effective amount of a cardiotonic agent or a bronchodilating agent dispersed in a pharmaceutically acceptable carrier are administered to a mammalian host.
摘要:
The invention relates to novel compounds, 2,9-dihydro(6 or 7)-3-oxo-2,3,4,5-tetrahydropyridazinyl)pyrazolo[4,3-b]benzoxazines. The claimed compounds are inhibitors of phosphodiesterase fraction III and have potent positive inotropic activity. These compounds are useful as cardiotonics or platelet aggregation inhibitors.This invention also pertains to compositions comprising an effective amount of the compounds, to methods for preparing the claimed compounds and to methods for treating a mammal with the compounds.
摘要:
The invention is directed to 4h-benzo[1,4]oxazin-3-ones useful as peroxisome proliferator activated receptor gamma (PPARγ) agonists or antagonists. Pharmaceutical compositions comprising compounds of the present invention and methods of treating conditions such as NIDDM and obesity are also disclosed.
