Belinostat (PXD101)是一种新型的HDAC抑制剂,IC50为27 nM,对抵抗Cisplatin的肿瘤有效。一种新型HDAC抑制剂
Information
Belinostat (PXD101) Belinostat (PXD101, NSC726630, PX-105684) is a novel HDAC inhibitor with IC50 of 27 nM in a cell-free assay, with activity demonstrated in cisplatin-resistant tumors. Belinostat (PXD101) induces autophagy .
In vitro
Belinostat inhibits the growth of tumor cells (A2780, HCT116, HT29, WIL, CALU-3, MCF7, PC3 and HS852) with IC50 from 0.2-0.66 μM. PD101 shows low activity in A2780/cp70 and 2780AD cells, which are cisplatin and doxorubicin-resistant derivatives of A2780 cells. Belinostat could induce apoptosis through PARP cleavage and acetylation of histones H3/H4. Belinostat inhibits bladder cancer cell growth, especially in 5637 cells, which shows accumulation of G0-G1 phase, decrease in S phase and increase in G2-M phase. The growth inhibitory activity of belinostat on cell lines is not strongly influenced by the multidrug-resistant phenotype, whereas the activity of docetaxel is clearly affected. Belinostat could enhance the growth inhibitory activity of docetaxel or carboplatin in OVCAR-3 and A2780 cells. Belinostat also shows enhanced tubulin acetylation in ovarian cancer cell lines. A recent study shows that Belinostat activates protein kinase A in a TGF-β signaling-dependent mechanism and decreases survivin mRNA.
In vivo
Belinostat indicates significant tumor growth delay in A2780 and A2780/cp70 xenograft at a dose of 10mg/kg with no effects on the body weight. Belinostat also induces p21WAF1, HDAC core and cell communication genes in mouse bladder tumors. Belinostat monotherapy induces dose-proportional antitumor effects with TGI of 47% at a dose of 100mg/kg in A2780 xenograft. The combination of Belinostat (100 mg/kg) with carboplatin (40 mg/kg) could delay tumor growth from 18.6 days to 22.5 days. Combining with bortezomib, Belinostat results in great tumor inhibition and gastrointestinal toxicity in mice with bortezomib-resistant UMSCC-11A xenograft.
