OICR-9429 是一个新颖的相互作用的小分子Wdr5-MLL 拮抗剂，IC50是 5 uM，在体外抑制急性髓性白血病细胞。

MM-589 is a potent WD repeat domain 5 (WDR5) inhibitor and mixed lineage leukemia (MLL) protein-protein interaction.

MM-589 TFA is a potent WD repeat domain 5 (WDR5)inhibitor and mixed lineage leukemia (MLL) protein-protein interaction.

AS-99 TFA is a first-in-class, potent and selective ASH1L histone methyltransferase inhibitor (IC50= 0.79 μM, Kd= 0.89 μM) with anti-leukemic activity. AS-99 TFA blocks cell proliferation, induces apoptosis and differentiation, downregulates MLL fusion target genes, and reduces the leukemia burden in vivo[1]. AS-99 TFA is tested against a panel of 20 histone methyltransferases, including NSD1, NSD2, NSD3, and SETD2. NO significant inhibition is observed at 50 μM of AS-99 TFA on any of the tested histone methyltransferases, indicating over 100-fold selectivity towards ASH1L[1].AS-99 TFA shows effect on the growth of the MLL leukemia cells (MV4;11, MOLM13, KOPN8, RS4;11) with the GI50 values ranging from 1.8 μM to 3.6 μM[1].AS-99 (1-8 μM; 7 days) TFA also induces apoptosis in the MLL leukemia cells, but not in the K562 cells, as assessed by the quantification of the Annexin V positive cells[1].AS-99 TFA suppresses MLL fusion driven transcriptional programs[1]. AS-99 (30 mg kg; i.p.; q.d., treated for 14 consecutive days) TFA reduces leukemia burden in mice[1].AS-99 TFA is used for in vivo studies in mice, which reveals favorable exposure in plasma upon i.v. and i.p. administration (AUC = 9701 hr* ng mL and 10,699 hr* ng mL, respectively), suitable half-life (~5-6 h) and Cmax >10 μM[1].
