Abstract

Novel pyrazolopyridine-4-yl pyridazinone derivatives serve as phosphodiesterase inhibitors and are useful compounds for use in pharmaceutical products. Specifically, the compounds of the present invention are pyrazolopyridine-4-yl pyridazinone derivatives represented by the following general formula (1): (Example: 6-(2-ethyl-7-methoxy-pyrazolo[1,5-a]pyridine-4-yl)-5-methyl-4, 5-dihydro-3(2H)-pyridazinone).
