Definitions

  • the invention belongs to the field of medicinal chemistry, and more particularly, relates to a compound with Wee-1 kinase inhibitory effect, a preparation method thereof, and the use of the compound in the preparation of antitumor drugs.
  • Wee-1 protein kinase is an important negative regulator of cell cycle checkpoints.
  • Cell cycle checkpoints include the G1 phase checkpoint for the transition from G1 (cell quiescence) to S phase (DNA synthesis phase), the G2 phase checkpoint for the transition from G2 (preparation for cell division) to M (cell division), and the M Spindle checkpoint for the transition from metaphase (mid-phase) to anaphase (anaphase).
  • Wee-1 protein kinase plays an important role in the G2 phase checkpoint.
  • the entry of cells into M phase depends on the kinase activity of CDK1.
  • Wee-1 inhibits the activity of CDK1 by phosphorylating Tyr 15 of CDK1 protein, preventing cells from entering M phase (cell division phase).
  • Polo kinase kinase phosphorylates Wee-1, activates the degradation of Wee-1 protein, and promotes cell entry into M phase.
  • Wee-1 kinase activity determines the activity of the G2 checkpoint, which in turn regulates the transition of cells from G2 to M phase.
  • Cell cycle checkpoints are mainly activated after DNA damage and play an important role in DNA repair in cells. Normal activation of cell cycle checkpoints arrests the cell cycle and promotes DNA repair. Inhibit the function of checkpoints, DNA damage cannot be repaired, and cells undergo apoptosis. Compared with normal cells, various tumor cells mainly rely on the activation of the G2 checkpoint to repair DNA damage and avoid apoptosis due to the impaired function of p53, an important protein of the G1 phase checkpoint. Therefore, inhibiting the G2 phase checkpoint can selectively kill tumor cells.
  • Wee-1 kinase determines the repair or death of tumor cells after DNA damage, and inhibition of Wee-1 activity can promote unrepaired tumor cells after DNA damage to enter M period, induce apoptosis.
  • Wee-1 is also involved in DNA synthesis, DNA homology repair, post-translational modification of chromosomal histones and other functions closely related to tumorigenesis and development.
  • Wee-1 expression is greatly elevated in a large number of tumors including liver, breast, cervical, melanoma and lung cancer.
  • the high expression of Wee-1 is positively correlated with tumor development and poor prognosis, suggesting that Wee-1 kinase may be involved in tumor occurrence and development.
  • Studies in in vitro cell models and in vivo animal models have shown that inhibiting Wee-1 activity while inducing DNA damage can significantly inhibit the growth of various tumors.
  • AstraZeneca's Wee-1 inhibitor AZD1775 (MK-1775, Adavosertib) has entered the phase 2 clinical research stage, and more than 30 clinical trials are under development.
  • Patents related to AZD1775 include US20070254892, WO2007126122, EP2213673, WO2008133866, WO2011034743 and the like.
  • Abbott and Abbvie have also conducted research on Wee-1 inhibitors, and related patents mainly include US2012220572, WO2013126656, WO2013012681, WO2013059485, WO2013013031 and so on.
