About Azenosertib
Azenosertib is a novel, selective, and orally bioavailable inhibitor of WEE1 (搜索) currently being evaluated in monotherapy and combination clinical studies in ovarian cancer (搜索) and additional tumor types. WEE1 acts as a master regulator of the G1-S and G2-M cell cycle checkpoints, through negative regulation of both CDK1 and CDK2, to prevent replication of cells with damaged DNA. By inhibiting WEE1, azenosertib enables cell cycle progression, despite high levels of DNA damage, thereby resulting in the accumulation of DNA damage and leading to mitotic catastrophe and cancer cell death.
