Abstract
The application belongs to the field of pharmaceutical chemistry, and relates to a compound containing cycloalkenyl pyridine, in particular to a compound shown in a formula I or pharmaceutically acceptable salt thereof, a preparation method thereof, a pharmaceutical composition containing the compound and application thereof in treating diseases (such as cancers).
Description
Technical Field
The present application relates to compounds containing cycloalkenyl-pyridinium groups, methods for their preparation, pharmaceutical compositions containing the compounds, and their use in the treatment of related diseases, such as cancer.
Background
Wee1 protein is a cell cycle regulatory protein, which is one of important members of serine/threonine protein kinase family, and by regulating the phosphorylation state of CDK1, wee1 protein affects the binding of CDK1 to cyclin B to block the transition from G2 phase to M phase, thereby ensuring DNA replication accuracy and chromatin integrity. Thus, the Wee1 protein is a key protein kinase involved in the G2/M checkpoint and DNA damage repair process of the cell cycle. On the other hand, during normal cell cycle progression, p53 protein can also monitor genome integrity by regulating G1/S phase and DNA damage examination, but p53 gene deletion in most tumor cells results in defective cell cycle G1/S checkpoints. Therefore, these p 53-deleted tumor cells are more dependent on the G2/M checkpoint during DNA replication and damage repair, resulting in high expression of Wee1 protein kinase. Theoretically, by inhibiting the activity of Wee1 protein kinase, DNA damage of these p 53-deleted tumor cells cannot be repaired in time to enter M phase, so that genome instability and chromosome deletion are caused, mitosis disasters are caused, and tumor cells are caused to die.

When trade names are presented herein, it is intended to refer to their corresponding commercial products or active ingredients thereof.
In some embodiments, the "one or more" is selected from one, two, three, four, five, or six. In some embodiments, the "one or more" is selected from one, two, or three. In some embodiments, the "one or more" is selected from one, or two.
The term "substituted" means that any one or more hydrogen atoms on a particular atom is substituted with a substituent, provided that the valence of the particular atom is normal and the substituted compound is stable.

The term "optionally" or "optionally" means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. For example, ethyl "optionally" substituted with halogen means that ethyl can be unsubstituted (CH 2CH3), monosubstituted (e.g., CH 2CH2 F), polysubstituted (e.g., CHFCH 2F、CH2CHF2, etc.), or fully substituted (CF 2CF3).
