Protein Arginine Methyltransferases (PRMTs) are crucial players in diverse biological processes, and dysregulation of PRMTs has been linked to various human diseases, especially cancer. Therefore, small molecules targeting PRMTs have profound impact for both academic functional studies and clinical disease treatment. Here, we report the discovery of N1-(2-((2-chlorophenyl)thio)benzyl)-N1-methylethane-1,2-diamine (28d, DCPR049-12), a highly potent inhibitor of type I PRMTs that has good selectivity against a panel of other methyltransferases. Compound 28d effectively inhibits cell proliferation in several leukemia cell lines and reduces the cellular asymmetric arginine dimethylation levels. Serving as an effective inhibitor, 28d demonstrates the mechanism of cell killing in both cell cycle arrest and apoptotic effect as well as downregulation of the pivotal mixed lineage leukemia (MLL) fusion target genes such as HOXA9 and MEIS1, which reflects the critical roles of type I PRMTs in MLL leukemia. These studies present 28d as a valuable inhibitor to investigate the role of type I PRMTs in cancer and other diseases.

The reaction of dialkyl benzoylphosphonates 1 with trialkyl phosphites leads to the formation of carbene intermediates 3 via the anionic intermediates 2. The carbene intermediates 3 (R = 2-PhO, 2-PhOCH2, and 2-PhS) have been generated by heating the corresponding 2-substituted dialkyl benzoylphosphonates with trimethyl phosphite and their subsequent reactions investigated. Reactions proceed either by intermolecular trapping of the carbene intermediates by trimethyl phosphite to give novel ylidic phosphonates 4, or by intramolecular routes involving carbene insertion into the π-system of the phenyl ring in the substituent. Studies using methyl-substituted derivatives have shown that the formation of the thioxanthenylphosphonate 15 (X = S, R′ = R″ = Me) proceeds via a spiro diene intermediate 14 (X = S, R′ = R″ = Me).
