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.

Disclosed are progestin agonists having the following formula: ##STR1## W is absent or --CH.dbd.CH--; R.sup.1 are independently selected from the group consisting of halogen, --CF.sub.3, and NO.sub.2, or both R.sup.1 may be joined to form a bi-radical which is --CH.dbd.CHCH.dbd.CH--; R.sup.3 are independently selected from the group consisting of hydrogen, C.sub.1-6 branched or linear alkyl, halogen and --CF.sub.3, with the proviso that R.sup.3 at the 3-position must be H where R.sup.3 at the 4-position is H, or both R.sup.3 may be joined to form a bi-radical selected from the group consisting of --CH.dbd.CHCH.dbd.CH--, --C(NC.sub.1-4 alkyl.sub.2)=CHCH.dbd.CH-- and --(CH.sub.2).sub.4 --; R.sup.5 is selected from the group consisting of H and Me; with the proviso that only one of R.sup.1 and R.sup.3 forms the fused bi-radical; and the stereoisomers.
摘要:
The invention relates to a process for the synthesis of compounds of the formula I ##STR1## wherein R.sub.1 -R.sub.5 are as defined herein. The process is a multistep process which comprises acylating a 2-benzoxazolinone with an alkanoic anhydride to form an acylated carbamate, hydrolyzing the carbamate, reacting the resultant aminophenol with haloalkanoyl halide to form a substituted benzoxazine, reacting the benzoxazine with an aldehyde, alkylating the resultant aminomethyl compound with an alkylating agent to form a quaternary ammonium salt, reacting the salt with an alkali metal cyanide to form a nitrile, hydrolyzing the nitrile and reacting the resultant carboxylic acid with hydrazine.The compounds are useful as cardiotonic and vasodilating agents and as inhibitors of phosphodiesterase fraction III and platelet aggregation. In addition, the compounds are active as smooth muscle relaxants and bronchodilators.
