Definitions
- the invention relates to a crystal form of a morpholine-substituted benzopyrimidine compound and a preparation method thereof.
- DNA double-strand breaks can cause loss of genetic material, genetic recombination, and then cancer or cell death.
- DDR DNA damage response
- DNA double-strand break repair mainly includes two types: homologous end linking (HR) repair and non-homologous end linking (NHEJ) repair.
- DDR initial damage factors such as MRN will detect and recognize the damage site, recruit phosphatidylinositol kinase family members (ATM, ATR, DNA-PK), phosphorylate H2AX to promote the formation of ⁇ H2AX, and recruit related signaling proteins (such as 53BP1, Chk1, Chk2, BRCA1, NBS1) and other transduction damage signals, so that cells enter a cell cycle arrest state and recruit related repair proteins to repair damaged DNA.
- ATM phosphatidylinositol kinase family members
- ATR phosphatidylinositol kinase family members
- DNA-PK phosphorylate H2AX to promote the formation of ⁇ H2AX
- related signaling proteins such as 53BP1, Chk1, Chk2, BRCA1, NBS1
- DNA-PK is mainly aimed at non-homologous end double-strand breaks. It consists of six core factors: KU70, KU80, DNA-PKcs, CRCC4, ligase IV and Artemis.
- KU molecules are specifically linked to the double-strand damage through a pre-formed channel, respectively It binds to the end of the DNA chain, and then slides along the DNA chain for a distance in an ATP-dependent manner to form a KU-DNA complex, which attracts DNA-PKcs to the damaged site, binds with it and activates the kinase activity, and then phosphorylates to participate in A series of proteins that repair and damage signaling to complete the repair.
- the present invention aims to discover a DNA-PK small molecule inhibitor, which can inhibit DNA-PK activity through combined use with radiotherapy and chemotherapy drugs, thereby greatly reducing tumor DNA repair and inducing cells to enter apoptosis process. To a large extent, it can overcome the problem of resistance to radiotherapy and chemotherapy, and enhance the inhibitory effect on various tumors such as small cell lung cancer, head and neck cancer, colorectal cancer, and pancreatic cancer. Such compounds have good activity and show excellent effects and functions, and have broad prospects.
