Discovery of a potent MLL1 and WDR5 protein-protein interaction inhibitor with in vivo antitumor activity

MLL1-WDR5 interaction is essential for the formation of MLL core complex and its H3K4 methyltransferase activity. Disrupting MLL1-WDR5 interaction has been proposed as a potential therapeutic approach in the treatment of leukemia. A “toolkit” of well-characterized chemical probe will allow exploring animal studies. Based on a specific MLL1-WDR5 PPI inhibitor (DDO-2117), which was previously reported by our group, we conducted a bioisosterism approach by click chemistry to discover novel phenyltriazole scaffold MLL1-WDR5 interaction blockers. Here, our efforts resulted in the best inhibitor 24 (DDO-2093) with high binding affinity (Kd = 11.6 nM) and with improved drug-like properties. Both in vitro and in vivo assays revealed 24 could efficiently block the MLL1-WDR5 interaction. Furthermore, 24 significantly suppressed tumor growth in the MV4-11 xenograft mouse model and showed a favorable safety profile. We propose 24 as a chemical probe that is suitable for in vivo pharmacodynamic and biological studies of MLL1-WDR5 interaction.

Discovery of DDO-2213 as a Potent and Orally Bioavailable Inhibitor of the WDR5-Mixed Lineage Leukemia 1 Protein-Protein Interaction for the Treatment of MLL Fusion Leukemia

WD repeat-containing protein 5 (WDR5) is essential for the stability and methyltransferase activity of the mixed lineage leukemia 1 (MLL1) complex. Dysregulation of theMLL1gene is associated with human acute leukemias, and the direct disruption of the WDR5-MLL1 protein-protein interaction (PPI) is emerging as an alternative strategy for MLL-rearranged cancers. Here, we represent a new aniline pyrimidine scaffold for WDR5-MLL1 inhibitors. A comprehensive structure-activity analysis identified a potent inhibitor 63 (DDO-2213), with an IC50of 29 nM in a competitive fluorescence polarization assay and aKdvalue of 72.9 nM for the WDR5 protein. Compound 63 selectively inhibited MLL histone methyltransferase activity and the proliferation of MLL translocation-harboring cells. Furthermore, 63 displayed good pharmacokinetic properties and suppressed the growth of MV4-11 xenograft tumors in mice after oral administration, first verifying thein vivoefficacy of targeting the WDR5-MLL1 PPI by small molecules.

The synthesis and bioactivity of pyrrolo[2,3-d]pyrimidine derivatives as tyrosine kinase inhibitors for NSCLC cells with EGFR mutations

EGFR mutations are an ongoing challenge in the treatment of NSCLC, and demand continuous updating of EGFR TKI drug candidates. Pyrrolopyrimidines are one group of versatile scaffolds suitable for tailored drug development. However not many precedents of this type of pharmacophore have been investigated in the realm of third generation of covalent EGFR-TKIs. Herein, a series of pyrrolo[2,3-d]pyrimidine derivatives able to block mutant EGFR activity in a covalent manner were synthesized, through optimized Buchwald-Hartwig C–N cross coupling reactions. Their preliminary bioactivity and corresponding inhibitory mechanistic pathways were investigated at molecular and cellular levels. Several compounds exhibited increased biological activity and enhanced selectivity compared to the control compound. Notably, compound 12i selectively inhibits HCC827 cells harboring the EGFR activating mutation with up to 493-fold increased efficacy compared to in normal HBE cells. Augmented selectivity was also confirmed by kinase enzymatic assay, with the test compound selectively inhibiting the T790 M activating mutant EGFRs (IC50 values of 0.21 nM) with up to 104-fold potency compared to the wild-type EGFR (IC50 values of 22 nM). Theoretical simulations provide structural evidence of selective kinase inhibitory activity. Thus, this series of pyrrolo[2,3-d]pyrimidine derivatives could serve as a starting point for the development of new EGFR-TKIs.
