Targets/IC50/Ki

(Cell-free assay)
27 nM
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. This compound could induce apoptosis through PARP cleavage and acetylation of histones H3/H4. It 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 this chemical on cell lines is not strongly influenced by the multidrug-resistant phenotype, whereas the activity of docetaxel is clearly affected. It could enhance the growth inhibitory activity of docetaxel or carboplatin in OVCAR-3 and A2780 cells. This compound also shows enhanced tubulin acetylation in ovarian cancer cell lines. A recent study shows that it activates protein kinase A in a TGF-β signaling-dependent mechanism and decreases survivin mRNA.
Kinasanalys
Histonedeacetylasaktivitet
Subkonfluenta kulturer skördas och tvättas två gånger i iskall PBS och pelleteras genom centrifugering vid 200 × g i 5 min. Cellpelleten resuspenderas i två volymer lysbuffert [60 mM Tris-buffert (pH 7,4) innehållande 30 % glycerol och 450 mM NaCl] och lyseras genom tre frys-(torris) tin-(30 °C vattenbad) cykler. Cellrester avlägsnas genom centrifugering vid 1,2 × 104 g i 5 min, och supernatanten lagras vid –80 °C. Histon H4-peptid (sekvens SGRGKGGKGLGKGGAKRHRK motsvarande de 20 NH2-terminala resterna) acetyleras av ett rekombinant protein innehållande hypoxantin-aminopterin-tymidin-domänen av p300, med [3H]acetyl CoA som acetatkälla. H4-peptid (100 μg) blandas med hypoxantin-aminopterin-tymidin-buffert (50 mM Tris HCl pH 8,0, 5 % glycerol, 50 mM KCl och 0,1 mM EDTA), 1 mM DTT, 1 mM 4-(2-aminoetyl)bensenesulfonylfluorid, 1 × kompletta proteashämmare, 50 μL renat p300 och 1,85 m [3H]acetyl CoA (4,50Ci/mmol) i en slutvolym på 300 μL och inkuberas vid 30 °C i 45 min. P300-proteinet avlägsnas genom inkubation med 20 μL 50 % Ni-agarooskulor i 1 timme vid 4 °C och centrifugering. Supernatanten appliceras på en 2 mL Sephadex G15-kolonn, och flödet samlas upp. En milliliter destillerat H2O appliceras försiktigt, och fraktioner med tre droppar samlas upp; detta upprepas tills 4–5 mL destillerat H2O har tillsatts, och ~40 fraktioner samlas upp. Tre mikroliter av varje fraktion späds i 2 mL scintillationsvätska och räknas i en scintillationsräknare för att identifiera fraktionerna som innehåller den märkta peptiden. Dessa fraktioner pools, och 1 μL av det kombinerade provet mäts för att bedöma radioaktiviteten i varje peptidbatch (3-7×103 cpm/μL). För aktivitetsanalyser utförs reaktionen i en total volym på 150 μL buffert [60 mM Tris (pH 7,4) innehållande 30 % glycerol] innehållande 2 μL cellextrakt och, om det används, 2 μL av denna förening. Reaktionen startas genom tillsats av 2 μL [3H]-märkt substrat (acetylerad histon H4-peptid motsvarande de 20 NH2-terminala resterna). Proverna inkuberas vid 37 °C i 45 min, och reaktionen stoppas genom tillsats av HCl och ättiksyra (0,72 respektive 0,12 M slutkoncentrationer). Frigjort [3H]acetat extraheras till 750 μL etylacetat, och proverna centrifugeras vid 1,2× 104 g i 5 min. Den övre fasen (600 μL) överförs till 3 mL scintillationsvätska och räknas.
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. This compound also induces p21WAF1, HDAC core and cell communication genes in mouse bladder tumors. Its monotherapy induces dose-proportional antitumor effects with TGI of 47% at a dose of 100mg/kg in A2780 xenograft. The combination of this chemical (100 mg/kg) with carboplatin (40 mg/kg) could delay tumor growth from 18.6 days to 22.5 days. Combining with bortezomib, it results in great tumor inhibition and gastrointestinal toxicity in mice with bortezomib-resistant UMSCC-11A xenograft.

Vanliga frågor (Frequently Asked Questions)

Fråga 1:
Could you please give some suggestions for the use of it in vivo (i.p. injection)?

Svar:
For I.P. injection, it can be dissolved in 2% DMSO+30% PEG 300+ddH2O at 10 mg/ml clearly. When preparing the solution, please dissolve this compound in DMSO clearly first. Then add PEG, after they mixed well, then dilute with water. Hope this information is useful to you.
