The synthesis of a series of 6-(substituted-phenyl)-1,2,4-triazolo[4,3-b]pyridazines (VIII) is reported. Some of these derivatives show activity in tests predictive of anxiolytic activity [(a) protection against pentylenetetrazole-induced convulsions; (b) thirsty rat conflict procedure]. They also represent a new class of compound which inhibits [3H]diazepam binding. Structure--activity correlations

We report a series of phenyl substituted pyridazin-3-ones substituted with morpholino-pyrimidines. The SAR of the phenyl was explored and their c-Met kinase and cell-based inhibitory activity toward c-Met driven cell lines were evaluated. Described herein is a potent c-Met inhibitor by structural modification of the parent morpholino-pyridazinone scaffold, with particular focus on the phenyl and pyrimidine substituents.
