시험관 내(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.
키나아제 분석
Histone Deacetylase Activity
Subconfluent cultures are harvested and washed twice in ice cold PBS and pelleted by centrifugation at 200 × g for 5 min. The cell pellet is resuspended in two volumes of lysis buffer [60 mM Tris buffer (pH 7.4) containing 30% glycerol and 450 mM NaCl] and lysed by three freeze (dry ice) thaw (30 °C water bath) cycles. Cell debris is removed by centrifugation at 1.2 × 104 g for 5 min, and the supernatant is stored at −80 °C. Histone H4 peptide (sequence SGRGKGGKGLGKGGAKRHRK corresponding to the 20 NH2-terminal residues) is acetylated by a recombinant protein containing the hypoxanthine-aminopterin-thymidine domain of p300, using [3H]acetyl CoA as a source of acetate. H4 peptide (100 μg) is mixed with hypoxanthine-aminopterin-thymidine buffer (50 mM Tris HCl pH 8.0, 5% glycerol, 50 mM KCl, and 0.1 mM EDTA), 1 mM DTT, 1 mM 4-(2-aminoethyl) benzenesulfonylfluoride, 1 × complete protease inhibitors, 50 μL of purified p300, and 1.85 m [3H]acetyl CoA (4.50Ci/mmol) in a final volume of 300 μL and incubated at 30 °C for 45 min. The p300 protein is removed by incubation with 20 μL of 50% Ni-agaroase beads for 1 hour at 4 °C and centrifugation. The supernatant is applied to a 2 mL Sephadex G15 column, and the flow through is collected. One milliliter of distilled H2O is gently applied, and three drop fractions are collected; this is repeated until 4–5 mL of distilled H2O has been added, and ∼40 fractions are collected. Three microliters of each fraction are diluted in 2 mL of scintillation fluid and counted in a scintillation counter to identify the fractions containing the labeled peptide. These fractions are pooled, and 1 μL of the combined sample is measured to assess the radioactivity in every peptide batch (3-7×103 cpm/μL). For activity assays, the reaction is carried out in a total volume of 150 μL of buffer [60 mM Tris (pH 7.4) containing 30% glycerol] containing 2 μL of cell extract and, where used, 2 μL of this compound. The reaction is started by the addition of 2 μL of [3H] labeled substrate (acetylated histone H4 peptide corresponding to the 20 NH2-terminal residues). Samples are incubated at 37 °C for 45 min, and the reaction stopped by the addition of HCl and acetic acid (0.72 and 0.12 M final concentrations, respectively). Released [3H]acetate is extracted into 750 μL of ethyl acetate, and samples are centrifuged at 1.2× 104 g for 5 min. The upper phase (600 μL) is transferred to 3 mL of scintillation fluid and counted.
생체 내(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.

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

답변:
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.
