Synthesis and pharmacological activity of 4-carbamoyl-6-beta-thienyl-4,5-dihydropyridazin-3-(2H)ones
A new series of 4-carbamoyl-6-beta-thienyl-4,5-dihydropyridazin-3-(2H)ones 4a-g have been synthesized and tested for their anti-inflammatory and analgesic properties. Among the tested compounds, only 4f at 1 mmole/Kg showed antiinflammatory activity that was comparable with that of indomethacin (5 mg/Kg) though of shorter duration. Compounds 4a, 4e and especially 4g at 0.2 mmoles/Kg displayed relevant analgesic activity, 4g being the most potent derivative in the writhing test. Compounds 4c and 4g were found to possess analgesic activity also in the hot plate test

A facile synthesis of 3-aryl-4-pyrazole acetic acids and of their 4,5-dihydro derivatives
Antihypertensive and antithrombotic activities of 6-(substitutedphenyl)-5-hydroxymethyl-4,5-dihydro-3(2H)pyridazinones
The synthesis of a series of 6-(4R-phenyl)-5-hydroxymethyl-4,5-dihydro-3(2H)pyridazinones is reported. The compounds were evaluated for their oral antihypertensive activity in rats and some of them [(V b), R = NH2] and [(V c), R = NHCOCH3] were found to induce a high decrease in systolic blood pressure. Moreover all the compounds displayed an antithrombotic activity comparable to, or greater than, that of ASA
