Structure-based virtual screening discovers novel PKMYT1 inhibitors

PKMYT1, a member of the WEE family, plays a crucial role in the cell cycle by specifically phosphorylating CDK1-CyclinB at Tyr15 and Thr14. Recent investigations have revealed that the amplification of CCNE1 and the inhibition of PKMYT1 kinase collectively result in synthetic lethality, further indicating that PKMYT1 is promising as an effective target for tumor therapy. Existing PKMYT1 inhibitors are mostly derivatives of RP-6306 or pan-inhibitors, limiting their further development. Herein, we conducted virtual screening of a natural product library, and
