摘要:[1,2,4]triazolo[1,5-c]quinazoline compounds of the formula wherein R1 is optionally substituted phenyl, pyridyl, furyl thienyl, dihydro or tetrahydro furanyl or thienyl, pyranyl, or 0-ribofuranosyl; R2 is hydrogen or lower alkyl; X is oxygen or NR3, R3 is as defined in the claims, and ring A is unsubstituted or substituted as set forth in the claims. The compounds wherein X is N-R3 are especially useful as adenosine antagonists and for the treatment of asthma. The compounds wherein X is oxygen are useful as benzodiazepine antagonists and as intermediates in the synthesis of the compounds wherein X is N-R3.
