The disposition of [14C]2,3-dihydrophthalazine-1,4-dione, a potent hypolipidaemic agent, has been determined after both intravenous and oral administration. Both the routes of administration afforded multi-exponential disposition with an estimated t1/2 of approximately 75 h. After oral administration, the drug was observed

The reactivity of 5-amino-2,3-dihydro-phthalazine-1,4-dione (luminol) and phthalic hydrazide with hydroxyl radicals was studied. HO*-radicals were generated by the Fenton reaction as well as by water radiolysis. Both luminol and phthalic hydrazide react with hydroxyl radicals under intense chemiluminescence (CL) emission.

2,3-Dihydrophthalazine-1,4-diones were observed to be potent anti-inflammatory agents as well as capable of protecting against endotoxin shock in mice at 8 mg/kg i.p. These agents blocked both locally- and centrally-induced pain at 8 mg/kg i.p. In part they appear to

2,3-Dihydrophthalazine-1,4-dione derivatives demonstrated potent cytotoxicity against the growth of murine leukemia cells and human single cell suspension, i.e. Tmolt3 leukemia and HeLa-S3, as well as colon adenocarcinoma and KB nasopharynx. However, only select compounds demonstrated activity against bronchogenic lung, osteosarcoma
