| Targets |
Histone methyltransferase SET7 (SETD7). DC-S239 is a selective inhibitor of SET7 with an IC50 of 4.59 μM. SET7 is a histone lysine methyltransferase that catalyzes the monomethylation of histone H3 at lysine 4 (H3K4me1), a mark associated with transcriptional activation. DC-S239 shows selectivity over other methyltransferases and epigenetic enzymes.

| ln Vitro |
At a dose of 100 μM, DC-S239 inhibits DNMT1, DOT1L, EZH2, NSD1, SETD8, and G9a by less than 45%, while SET7's inhibition rate surpasses 90% [1]. DC-S239 (0-100 μM, 120 h) has no discernible effect on the activity of HCT116 and DHL4 cells, but it can dose-dependently inhibit the proliferation of MCF7, HL60, and MV4-11 cells [1].
DC-S239 (0-100 μM, 120 h) dose-dependently inhibits proliferation of MCF7, HL60, and MV4-11 cells. The IC50 values for MCF7 and HL60 cells are 10.93 μM and 16.43 μM, respectively. However, DC-S239 has no significant effect on the viability of HCT116 and DHL4 cells. At 100 μM, DC-S239 inhibits SET7 by 90% while inhibiting DNMT1, DOT1L, EZH2, NSD1, SETD8, and G9a by less than 45%. |
| ln Vivo |
DC-S239 has shown anticancer activity in vitro. In vivo efficacy studies have not been extensively reported. The compound's selective inhibition of SET7 and its effects on cancer cell proliferation suggest potential for in vivo anticancer activity. Further studies are needed to evaluate the pharmacokinetic properties and therapeutic efficacy of DC-S239 in animal models.
|
| Enzyme Assay |
In vitro enzyme inhibition assays for DC-S239 are performed using purified recombinant SET7 enzyme and a suitable histone substrate (e.g., histone H3 or a peptide derived from the N-terminus of histone H3). The assay measures the transfer of 3H-methyl groups from S-adenosyl-[3H]methionine (SAM) to the substrate. DC-S239 is incubated at varying concentrations, and enzymatic activity is quantified by scintillation counting or using fluorescence-based detection methods. IC50 values are calculated from dose-response curves.

| Cell Assay |
Cell viability assay [1]
Cell Types: MCF7, HL60, DHL4, MV4-11 and HCT116 Cell line Tested Concentrations: 0-100 μM Incubation Duration: 120 h Experimental Results: Inhibition of MCF7 and HL60 with IC50 values of 10.93 μM and 16.43 μM, respectively . Cellular assays are conducted using cancer cell lines such as MCF7 (breast cancer), HL60 (acute myeloid leukemia), MV4-11 (leukemia), HCT116 (colorectal cancer), and DHL4 (lymphoma). Cells are treated with DC-S239 at concentrations ranging from 0 to 100 μM for 120 hours. Cell viability is assessed using MTT, CCK-8, or CellTiter-Glo assays. IC50 values for cell proliferation inhibition are calculated. The selectivity of DC-S239 is confirmed by testing against a panel of other methyltransferases. |
| Animal Protocol |
In vivo animal studies for DC-S239 have not been extensively reported in the literature. For potential in vivo studies, immunodeficient mice bearing tumor xenografts of sensitive cancer cell lines (e.g., MCF7 or HL60) could be used. DC-S239 would be administered via intraperitoneal or oral routes at various doses, and tumor volume would be monitored. Pharmacodynamic studies would assess SET7 inhibition in tumor tissues by measuring H3K4me1 levels.

| ADME/Pharmacokinetics |
DC-S239 has a molecular weight of 349.36 and molecular formula C15H15N3O5S. It is soluble in DMSO (125 mg/mL, 357.80 mM). The compound should be stored as powder at -20°C for 3 years or at 4°C for 2 years. In solvent, it is stable at -80°C for 6 months or at -20°C for 1 month. Stock solutions should be aliquoted to avoid repeated freeze-thaw cycles.
|
| Toxicity/Toxicokinetics |
Toxicological data for DC-S239 are primarily derived from in vitro cell viability assays. At concentrations up to 100 μM, DC-S239 shows differential effects on various cancer cell lines, with some lines being more sensitive than others. Standard laboratory safety precautions should be followed when handling DC-S239. No specific acute toxicity data have been reported in animal studies.
