Description

A heterocyclic compound and its preparation method and medical use Technical Field

[0001] The present invention belongs to the field of medical technology, and specifically relates to a heterocyclic compound, a preparation method thereof, a pharmaceutical composition containing the same, and its use as a PKMYT1 inhibitor in the treatment and / or prevention of diseases related to PKMYT1 activity. Background Art

[0002] CCNE1 encodes cyclin E1 (CyclinE1), which forms a complex with cyclin-dependent kinase 2 (CDK2) to drive cells from G1 into S phase. In cancer, CCNE1 gene amplification and / or dysregulated CyclinE1 expression often occur in the early stages of tumor development, forcing cancer cells to prematurely enter S phase. Excessive replication, a lack of origins, and an insufficient nucleotide pool lead to replication fork stalling, generating replication stress and DNA damage. When p53 is inactivated, cells enter mitosis with damaged DNA, leading to genomic instability. Cells have evolved a complex array of mechanisms to cope with DNA damage, collectively known as the DNA damage response (DDR). Cell cycle checkpoint activation is a crucial component of the DDR, regulating specific DNA repair mechanisms at each phase of the cell cycle, including the G1, S, G2, and mitotic checkpoints.

[0003] CCNE1 amplification is prevalent in multiple tumor types, including high-grade serous ovarian, uterine, and gastroesophageal cancers. In ovarian cancer, CCNE1 amplification is detected in approximately 20% of tumors, is often mutually exclusive with homologous recombination deficiency, and is enriched in tumors that relapse after platinum treatment. Targeting CDK2, a partner protein of Cyclin E1, can effectively inhibit the proliferation of CCNE1-amplified tumor cells. Although selective CDK2 inhibitors have entered the clinical stage, due to the structural similarities between CDKs, no inhibitors with precise selectivity have yet reached the market. As an alternative approach, identifying potential synthetic lethal targets for Cyclin E1 may provide much-needed new treatment options for CCNE1-amplified tumors. Recent studies have shown that PKMYT1 (membrane-associated tyrosine / threonine protein kinase 1) has been identified as a synthetic lethal target for CCNE1 amplification and is also an attractive target for treating some types of DDR cancers.

[0004] PKMYT1, also known as Myt1, is an evolutionarily conserved protein kinase. Its primary function is to inhibit CDK1 (cdc2) activity by phosphorylating CDK1 at Thr14 and Tyr15, thereby regulating the G2-M cell cycle and allowing cells to enter mitosis. PKMYT1 belongs to the WEE kinase family and is structurally similar to WEE, but it has been less studied. WEE1 is located in the nucleus and regulates the activity of CDK1 and CDK2 by phosphorylating Tyr15 residues on them. It participates in regulating the progression of the S, G2 / M, and M phase cell cycle checkpoints. PKMYT1, on the other hand, is primarily located in the cytoplasm, localized between the inner membrane of the Golgi apparatus and the endoplasmic reticulum. It is a membrane-associated inhibitory kinase that selectively regulates CDK1 phosphorylation and acts only at the G2 / M checkpoint. Compared to WEE1, PKMYT1 exhibits more restricted substrate specificity, as it phosphorylates only CDK1 and not the CDK2 complex. Targeting PKMYT1 has great clinical application prospects. Currently, only one selective inhibitor, RP-6306, has entered the clinical stage. Summary of the Invention

[0005] The present invention designed and synthesized a series of heterocyclic compounds and screened them for PKMYT1 activity. The research results showed that the compounds are potent PKMYT1 inhibitors with selective inhibitory effects on cells with CCNE1 gene amplification. The compounds and pharmaceutical compositions containing the compounds can be used to treat and / or prevent diseases related to PKMYT1 activity, such as cancers carrying CCNE1 gene amplification.
