We synthesized a compound library based upon a known specific inhibitor (BIX-01294) of the human G9a histone methyltransferase. Two compounds, BIX-01294 and its derivative TM2-115, inhibited P. falciparum 3D7 parasites in culture with IC(50) values of ~100 nM, values at least 22-fold more potent than their apparent IC(50) toward two human cell lines and one mouse cell line.
