体外研究
(In Vitro)

UNC1999, the first orally bioavailable inhibitor that has high in vitro potency for wild-type and mutant EZH2 as well as EZH1, a closely related H3K27 methyltransferase that shares 96% sequence identity with EZH2 in their respective catalytic domains. UNC1999 is highly selective for EZH2 and EZH1 over a broad range of epigenetic and non-epigenetic targets, competitive with the cofactor SAM, and non-competitive with the peptide substrate. UNC1999 has Ki values of 4,700 nM, 65 nM, 300 nM, and 1,500 nM for sigma1, sigma2, histamine H3, and NET, respectively. NC1999 selectively kills DB cells, a DLBCL cell line with the EZH2 Y641N mutation. UNC1999 displays a concentration- and time-dependent inhibition of DB cell proliferation (EC50=633±101 nM (n=3))[1].

体内研究
(In Vivo)

A single intraperitoneal (IP) injection of UNC1999 at 15, 50, or 150 mg/kg achieved high Cmax (9,700-11,800 nM) and exhibited dose linearity in male Swiss albino mice. Both the 150 and 50 mg/kg IP doses resulted in the plasma concentrations of UNC1999 above its cellular IC50 over the entire 24 h period while the 15 mg/kg IP dose led to the plasma concentrations of UNC1999 above its cellular IC50 for approximately 12 h. We next examined whether UNC1999 is orally bioavailable and are pleased to find that a single 50 mg/kg oral dose of UNC1999 achieved high Cmax (4,700 nM) and good exposure levels in male Swiss albino mice. The plasma concentrations of UNC1999 are maintained above its cellular IC50 for approximately 20 h following this single oral dose. It is worth noting that all doses including the 150 mg/kg IP dose are well tolerated by all test mice, and no adverse effects are observed[1].

Kinase Assay

EZH2 Y641N mutant is generated and assayed by BPS Bioscience. A series of dilutions of UNC1999 are prepared with 10% DMSO in HMT assay buffer and 5 μL of the dilution is added to a 50 μL reaction so that the final concentration of DMSO is 1% in all of reactions. All of the enzymatic reactions are conducted in duplicate at room temperature for 60 minutes (EZH2) and 180 minutes (EZH2 Y641N) in a 50 μL mixture containing HMT assay buffer, S-adenoslymethionine, enzyme, and UNC1999. These 50 μL reactions are carried out in wells of a HMT substrate pre-coated plate. After enzymatic reactions, the reaction mixtures are discarded and each of the wells is washed three times with TBST buffer, and slowly shaken with Blocking Buffer for 10 minutes. Wells are emptied, and 100 μL of diluted 1°antibody is added. The plate is then slowly shaken for 60 minutes at room temperature. As before, the plate is emptied and washed three times, and shaken with Blocking Buffer for 10 minutes at room temperature. After discarding the Blocking Buffer, 100 μL of diluted 2°antibody is added. The plate is then slowly shaken for 30 minutes at room temperature. As before, the plate is emptied and washed three times, and shaken with Blocking Buffer for 10 minutes at room temperature. Blocking Buffer is discarded and a mixture of the HRP chemiluminescent substrates is freshly prepared. 100 μL of this mixture is added to each empty well. Immediately, the luminescence of the samples is measured in a BioTek SynergyTM 2 microplate reader[1].

Cell Assay
[1]

DB cells, a diffuse-large B-cell lymphoma cell line harboring the EZH2 Y641N mutation, are obtained from ATCC and cultured in RPMI 1640 supplemented with 10% fetal bovine serum, antibiotics, and various concentration of UNC1999 (0.1, 0.2, 0.3, 0.4, 0.5, 1, 2, 3, and 5 μM) or UNC2400 and DMSO control. The medium containing the test compound or control is refreshed every three days. The numbers of viable cells from at least three independent experiments are measured using TC20 automated cell counter system. Total histones are prepared from cell nuclei using an acidic extraction protocol. About 1 microgram of total histones is separated using 15% of SDS-PAGE, transferred to PVDF membranes, and probed with histone antibodies. Antibodies used in this study are those against EZH2, general H3, and H3K27me3[1].

Animal Administration
[1]

Mice[1]
Standard PK studies are conducted using male Swiss albino mice at Sai Life Sciences. Four doses (15, 50, and 150 mg/kg IP, and 50 mg/kg PO) of UNC1999 are evaluated. Each study lasted 24 h. Plasma concentrations of UNC1999 reported at each of the eight time points (0.08, 0.25, 0.5, 1, 2, 4, 8, and 24 h post dosing) are the average values from 3 test animals.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
