Biological Activity

Description UNC0642 is a potent, selective inhibitor of histone methyltransferases G9a/GLP with IC50s less than 2.5 nM for G9a and GLP and shows more than 300-fold selective for G9a and GLP over a broad range of kinases, GPCRs, transporters, and ion channels.
Targets
G9a [1]
(Cell-free assay)		 GLP [1]
(Cell-free assay)
<2.5 nM <2.5 nM
In vitro UNC0642 is competitive with the peptide substrate and non-competitive with the cofactor SAM. The Ki of UNC0642 is determined to be 3.7 ± 1 nM. It is more than 20,000-fold selective for G9a and GLP over 13 other methyltransferases (IC50 > 50,000 nM) and more than 2,000-fold selective over PRC2-EZH2 (IC50 > 5,000 nM). UNC0642 displays high potency (IC50 < 150 nM) in reducing cellular levels of H3K9me2, low cell toxicity (EC50 > 3,000 nM), resulting in a good separation of functional potency and cell toxicity with a tox/function ratio (which is determined by dividing the EC50 value of the observed toxicity by the IC50 value of the functional potency) of > 45 in U2OS, PC3, and PANC-1 cells. UNC0642 reduces clonogenicity in PANC-1 cells in a concentration-dependent manner while it has no effect on clonogenicity in MDA-MB-231 cells[1].
In vivo For evaluation in vivo PK properties in male Swiss Albino mice, a single intraperitoneal (IP) injection (5 mg/kg) of UNC0642 results in a plasma Cmax (maximum concentration) of 947 ng/mL and an AUC (area under the curve) of 1265 hr*ng/mL. It displays modest brain penetration with a brain/plasma ratio of 0.33[1]. A single intraperitoneal (i.p.) injection dose of 5 mg/kg of UNC0642 is sufficient to inhibit G9a activity in adult mice. UNC0642 improves the life span and weight gain of m+/pΔS−U pups, produces long-lasting activation of PWS-associated genes, is apparently well tolerated and produces no notable acute toxicity, and does not interfere with the expression of the AS-associated Ube3a gene[2].

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    MDA-MB-231, PC3, and U2OS cells

  • Concentrations

    --

  • Incubation Time

    48 h

  • Method

    MDA-MB-231, PC3, and U2OS cells are cultured in RPMI with 10% FBS, PANC-1 cells in DMEM with 10% FBS. Cells are treated with inhibitors for 48 h. Cell viability assays are performed by incubating cells with 0.1 mg/mL of resazurin for 3-4 h. Resazurin reduction is monitored with 544 nm excitation, measuring fluorescence at 590 nm.
Animal Study:

[1]
  • Animal Models

    male Swiss Albino mice

  • Dosages

    5 mg/kg

  • Administration
