phthalazinone

Phthalazinone pyrazole is potent, selective, and orally bioavailable inhibitor of Aurora-A kinase. Aurora-A is overexpressed in a variety of tumor types and displays oncogenic activity.

Azelastine hydrochloride (Astelin) is a phthalazinone derivative with antihistaminergic activity.

PARP1-IN-8 (N-(3-chlorophenyl)-3-(1-oxo-4-phenylphthalazin-2(1H)-yl)propanamide) is an effective inhibito of PARP1 (IC50 = 97 nM).

HBV-IN-4, a derivative of phthalazinone, functions as a potent, orally active inhibitor of HBV DNA replication, exhibiting an IC50 value of 14 nM. It effectively induces the formation of genome-free capsids, demonstrating significant anti-HBV potency[1].
