2,3-Dihydrophthalazine-1,4-dione effectively lowers serum levels of cholesterol and triglycerides in Sprague Dawley rats after two weeks, after which the cholesterol levels continued to decline. The maximum serum lipid lowering effect on cholesterol or triglyceride levels was during the seventh and

Anti-cancer drugs, 3(1), 55-62 (1992-02-01)
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
J Schiller et al.
Free radical research, 30(1), 45-57 (1999-04-08)
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.

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

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
