SLIGHTLY BROWN TO BEIGE CRYSTALLINE POWDER | [Uses]
Phthalazine derivatives including copper and platinum complexes were induce the apoptosis in breast cancer cell lines and renal hyperemia. | [Uses]
Phthalazine is a heterocyclic organic compound isomeric with quinoxaline, cinnoline and quinazoline. Aminophthalazine compounds serve as effective phosphodiesterase (PDE) inhibitors. | [Definition]
ChEBI: An azaarene that is the 2,3-diaza analogue of naphthalene. The parent of the class of phthalazines. | [Synthesis Reference(s)]
