Abstract: The invention provides novel compounds of formula (I). ##STR1## and pharmaceutically acceptable salts thereof wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 which may be the same or different, represent hydrogen, halogen, lower alkyl, and lower alkoxy, or any adjacent two of R.sub.1 to R.sub.4 taken together represent an alkylene group containing from 3 to 5 carbon atoms or a 1,4-buta-1,3-dienylene group. The compounds are useful as anti-allergic agents.

Abstract: The compounds are prepared by cyclizing compounds of formula II ##STR2## wherein R.sup.2 is R.sup.1 or acyl.

Abstract: There are provided the compounds of the formula: ##STR1## (wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4, which may be the same or different, each represent hydrogen, a substituted or unsubstituted alkyl, aryl or aralkyl group, a nitro group, a cyano group or a halogen atom, R.sup.5 represents a quaternized nitrogen-containing heterocyclyl radical linked via a ring carbon atom, X represents one equivalent of an anion, R.sup.7 represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted, saturated or unsaturated heterocyclyl group which, if nitrogen-containing, is quaternized, linked via a ring carbon atom, and R.sup.6 either represents an alkyl group or, when R.sup.7 represents a quaternized nitrogen-containing heterocyclyl group, and the quaternized nitrogen atom is ortho to the linked ring carbon atom, may represent a methylene, dimethylene, trimethylene or alkyl-substituted ethenylene chain to that nitrogen atom.The compounds are selective herbicides.

Abstract: Various 1,5,6,11-tetrahydrobenzo[5,6]cyclohepta[1,2-b]pyrazolo[4,3-e]pyridine derivatives and their salts of the formulas ##STR1## wherein R.sub.1 is lower alkyl, phenyl, or phenyl-lower alkyl; R.sub.2 is hydrogen, lower alkyl or phenyl; R.sub.3 is hydrogen, halogen, or lower alkoxy; R.sub.4 is hydrogen, ##STR2## R.sub.5 is hydrogen or lower alkoxy; R.sub.6 is hydrogen, ##STR3## n is an integer from 2 to 6; R.sub.7 and R.sub.8 are the same or different and each is lower alkyl or R.sub.7 and R.sub.8 taken together with the N-atom form a heterocyclic ring of the formula ##STR4## wherein R.sub.9 is hydrogen or lower alkyl; R.sub.10 and R.sub.11 are the same or different and each is hydrogen or lower alkyl or R.sub.10 and R.sub.11 taken together with the N-atom form a heterocyclic ring of the formula ##STR5## wherein R.sub.9 is as defined above; are disclosed. These compounds possess useful anti-inflammatory activity as well as psychotropic activity.
