It relates to the use of compounds of formula (I'), or their pharmaceutically or veterinary acceptable salts, or their stereoisomers or mixtures thereof, as anticancer agents and as agents for generating induced pluripotent stem cells. Compounds of formula (I'), wherein R2' is an alcoxy group, a hydrocarbon chain or a ring system, and R1, R3, and R4 are as defined herein, are dual inhibitors of histone methyltransferases and DNA methyltransferases. It also relates to the compounds of formula (I'), or their pharmaceutically or veterinary acceptable salts, or their stereoisomers or mixtures thereof, wherein R2' is phenyl or 5- to 6-membered heteroaromatic ring, both optionally fused to another rings (i.e., compounds of formula (I)). It also relates to pharmaceutical or veterinary compositions containing compounds of formula (I).

reversible chemical probes that simultaneously inhibit the activity of two epigenetic targets, histone 3 lysine 9 methyltransferase (G9a) and DNA methyltransferases (DNMT), at nanomolar ranges. Enzymatic competition assays confirmed our design strategy: substrate competitive inhibitors. Next, an initial exploration around our hit 11 was pursued to identify an adequate tool compound for in vivo testing

the first time to an iridium(I)‐catalyzed C−H borylation reaction. By using either none or just a catalytic amount of a liquid, the mechanochemical C−H borylation of a series of heteroaromatic compounds proceeded in air to afford the corresponding arylboronates in good‐to‐excellent yields. A one‐pot mechanochemical C−H borylation/Suzuki–Miyaura cross‐coupling sequence for the directsynthesis of 2‐aryl

Arene C(sp2)-H bond borylation reactions provide rapid and efficient routes to synthetically versatile boronic esters. While iridium catalysts are well established for this reaction, the discovery and development of methods using Earth-abundant alternatives is limited to just a few examples. Applying an in situ catalystactivation method using air-stable and easily handed reagents, the iron-catalysed
Catalytic C−H borylation has been reported using newly designed iron complexesbearing a 4,5,6,7‐tetrahydroisoindol‐2‐ide‐based PNP pincer ligand. The reaction tolerated various five‐membered heteroarenes, such as pyrrole derivatives, as well as six‐membered aromatic compounds, such as toluene. Successful examples of the iron‐catalyzed sp3 C−H borylation of anisole derivatives were also presented.
