Abstact

CCNE1 amplification occurs in breast cancer and currently lacks effective therapies. PKMYT1 as a synthetic lethal target for CCNE1 amplification holds promise for the treatment of CCNE1-amplified breast cancer. Herein, we discover a series of 2-amino-[1,1'-biphenyl]-3-carboxamide derivatives as potent and selective PKMYT1 inhibitors using structure-based drug design. The representative compound 8ma exhibited excellent potency against PKMYT1, while sparing WEE1. It also suppressed proliferation of the CCNE1-amplified HCC1569 breast cancer cell line and showed synergistic cytotoxicity in combination with gemcitabine. PKMYT1 X-ray cocrystallography confirmed that introduction of key binding interactions between the inhibitors and residues Asp251 and Tyr121 of PKMYT1 greatly enhanced the potency and selectivity of the compounds.
