Abstract: Disclosed are heterocyclic-fused pyrazolo[3,4-d]pyridin-3-ones useful as benzodiazepine receptor modulators.

Abstract: Compounds having the formula ##STR1## in which R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl and R.sub.2 and R.sub.3 are C.sub.1 -C.sub.4 alkyl are insect repellents.

Abstract: Compounds of the formula ##STR1## wherein R.sub.1 is hydrogen, alkyl of 1 to 6 carbon atoms or phenyl (alkyl of 1 to 6 carbon atoms);R.sub.2 is hydrogen, alkyl of 1 to 4 carbon atoms or phenyl (alkyl of 1 to 6 carbon atoms);R.sub.3 is hydrogen or alkyl of 1 to 6 carbon atoms; and their use as antihypertensives.

Abstract: The present invention relates to new compounds of the general formula: ##STR1## in which X represents oxygen or sulphur and R represents a linear or branched alkyl group with 1 to 7 carbon atoms,and pharmaceutically acceptable acid addition salts thereof, having valuable cardiovascular properties.
