Investigation of tricyclic heterocycles related to the 2-arylpyrazolo[4,3-c]quinolin-3(5H)-ones, structures with high affinity for the benzodiazepine (BZ) receptor, led to the synthesis of 2-phenyl-[1,2,4]triazolo[1,5-c]quinazolin-5(6H)-one, a compound with 4 nM binding affinity to the BZ receptor. Analogues were prepared to assess the importance of the 2-substituent and ring substitution in modifying
Triazoloquinazoline compounds, and their methods of preparation,

[1,2,4]triazolo[1,5-c]quinazoline compounds of the formula ##STR1## wherein R.sub.1 is optionally substituted phenyl, pyridyl, furyl thienyl, dihydro or tetrahydro furanyl or thienyl, pyranyl, or 0-ribofuranosyl; R.sub.2 is hydrogen or lower alkyl; X is oxygen or NR.sub.3, R.sub.3 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--R.sub.3 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--R.sub.3.
