PXD-101 Chemical Properties,Uses,Production
Uses
Belinostat (PXD101; PX105684) is a potent HDAC inhibitor with an IC50 of 27 nM in HeLa cell extracts.
Definition
ChEBI: Belinostat is a hydroxamic acid-type histone deacetylase (HDAC) inhibitor with antineoplastic activity. It has a role as an antineoplastic agent and an EC 3.5.1.98 (histone deacetylase) inhibitor. It is a hydroxamic acid, a sulfonamide and an olefinic compound.
Biological Activity
Belinost at (PX105684; PXD101) is a potent, hydroxamate class pan-selective histone deacetylases (HDACs) inhibitor (IC50: class I HDAC1/2/3/8 = 41/125/30/216 nM, class IIA HDAC4/7/9 = 115/67/128 nM, class IIB HDAC6 = 82 nM) with anti-cancer efficacy in vitro and in vivo.
in vivo
Treatment of nude mice bearing human ovarian and colon tumor xenografts with Belinostat (10-40 mg/kg/day i.p.) daily for 7 days causes a significant dose-dependent growth delay with no obvious signs of toxicity to the mice. Growth delay is also observed for xenografts of cisplatin-resistant ovarian tumor cells. A marked increase in acetylation of H4 is detected in blood and tumor of mice 3 h after treatment with Belinostat (PXD101). The inhibition of growth of human tumor xenografts in mice, with no apparent toxicity[1]. Belinostat (PXD101) displays single-agent antitumor activity on human A2780 ovarian cancer s.c. xenografts which is enhanced via combination therapy with Carboplatin[2].
IC 50
HDAC6: 82 nM (IC50); HDAC: 27 nM (IC50, Hela cell)
