Description: Potent and selective G9a and GLP inhibitor
Chemical Name: 2-(4,4-Difluoro-1-piperidinyl)-6-methoxy-N-[1-(1-methylethyl)-4-piperidinyl]-7-[3-(1-pyrrolidinyl)propoxy]-4-quinazolinamine
Purity: ≥99% (HPLC)
Biological Activity for UNC 0642
UNC 0642 is a potent and selective G9a and GLP histone lysine methyltransferase inhibitor (IC50 < 2.5 nM) that exhibits >2,000-fold selectivity for G9a and GLP over PRC2-EZH2 and >20,000-fold selectivity over other methyltransferases. UNC 0642 reduces H3K9 dimethylation levels in MDA-MB-231 cells (IC50 = 110 nM), and displays modest brain penetration in vivo.

Epigenetics Scientific Review
Written by Susanne Müller-Knapp and Peter J. Brown, this review gives an overview of the development of chemical probes for epigenetic targets, as well as the impact of these tool compounds being made available to the scientific community. In addition, their biological effects are also discussed. Epigenetic compounds available from Tocris are listed.
Epigenetics in Cancer Poster
This poster summarizes the main epigenetic targets in cancer. The dysregulation of epigenetic modifications has been shown to result in oncogenesis and cancer progression. Unlike genetic mutations, epigenetic alterations are considered to be reversible and thus make promising therapeutic targets.
