摘要:
4-Substituted pyrazolo[3,4-d]pyrimidine derivatives and a method of synthesis for the derivatives are described. The 4-substituted pyrazolopyrimidine derivatives are useful as cardiotonic agents and antiarryhythmic agents.
摘要:
A process for the preparation of enantiomerically pure thienopyran derivatives of the formula ##STR1## is described. The thienopyran derivatives are relaxants of smooth muscle tone and as such are useful in vascular tissue for the treatment of hypertension disease, angina and other vascular disorders characterized by poor regional perfusion.
摘要:
6-substituted purinyl piperazine derivatives and a method of synthesis for the derivatives are described. The 6-substituted purinyl piperazine derivatives are useful as cardiotonic agents and antiarrhythmic agents.

摘要:
The synthesis of thienopyrimidine-2,4-dione derivatives and their urea intermediates is described. The novel urea intermediates and thienopyrimidine-2,4-dione derivatives are generally vasodilating agents and anti-hypertensive agents. The compounds are useful as cardiovascular agents.
摘要:
This invention concerns novel N-[(1H-imidazol-1-yl) and (1H-1,2,4-triazol-1-yl)alkyl]pyridinecarboxamides which are useful as inhibitors of thromboxane synthetase and/or as hypotensive agents in the treatment of hypertension and myocardial ischemia.
摘要:
This disclosure describes novel substituted thieno[3,4-b][1,5]benzoxazepin-10 (9H)-ones and thieno[3,4-b][1,5]benzothiazepin-10(9H)-ones which are useful as intermediates for the preparation of 10-[4-(substituted)-1-piperazinyl]thieno[3,4-b][1,5]benzoxazepines and 10-[4-(substituted)-1-piperazinyl]thieno[3,4-b][1,5]benzothiazepines which possess anti-psychotic or neuroleptic activity.
摘要:
Substituted thienopyrans and processes for preparing the thienopyrans are disclosed. The thienopyrans are useful as antihypertensive agents; antianginals are peripheral antivasoconstrictive agents.
摘要:
##STR1## Novel tetrahydropyrido[4,3-d]pyrimidines and their synthesis are described. These compounds are useful for the treatment of gastrointestinal diseases, and are particularly useful as cytoprotective agents to prevent ulcer formation.
