Various azaazulene derivatives were synthesized and their antiallergic activity was examined. The structure-activity relationship among various derivatives modified by introducing substituents at the 1-,2-, or 3-position of the azaazulene ring was investigated. The inhibitory activities on allergic histamine release of the compounds bearing a 5-tetrazolyl group at the 3-position were more potent than
Disclosed herein are 1,2-dihydro-2-oxo(or 2-thioxo)cyclohepta[b]-pyrrole-1-acetic acid derivatives having optional substitution at positions 3, on the cycloheptatriene ring and on the acetic acid side chain. The compounds are aldose reductase inhibitors and thus are useful for treating diabetic complications.
