Description

TECHNICAL FIELD

The present disclosure relates to a nitrogen-containing heterocyclic compound, pharmaceutical compositions thereof and use thereof

BACKGROUND

Cancer has become a frequent and common disease that poses a serious threat to human health and life. PI3K/AKt/mTOR signaling pathway is one of the many mechanisms that regulate the cell cycle and apoptosis, and dysregulation of one component of the pathway can lead to tumor development. Receptor tyrosine kinase (RTK) regulates the activation of the PI3K/AKt signaling pathway in response to activation of growth factors, including Insulin-like Growth Factors (IGF), Epidermal Growth Factor (EGF) and Epidermal Growth Factor (EGF). These growth factors, including Insulin-like Growth Factors (IGF), Epidermal Growth Factor (EGF), and Hepatocyte growth factor (HGF), activate RTK by phosphorylating tyrosine residues, while PI3K binds to phosphorylated tyrosine residues to activate the catalytic subunit of PI3K. p110α, the catalytic subunit of type IA PI3K, is activated and then activates PI3K by binding to p85α. After activation of the catalytic subunit of type IA PI3K, p110α activates PI3K by binding to p85α, which further phosphorylates phosphatidylinositol 4,5-bisphosphate (PIP2) to phosphatidylinositol 3,4,5-trisphosphate (PIP3). PIP3, as an important second messenger and mediator, recruits AKt from the cytoplasm to the membrane through its interactions with the PH domains of AKt. Mediates the membrane translocation of AKt, phosphatidylinositol-dependent kinase 1 (PDK1) and phosphatidylinositol-dependent kinase 2 (PDK2), respectively. Phosphorylation of Thr308 and Ser473 by PDK1 and phosphatidylinositol-dependent kinase 2 (PDK2), respectively, is required for AKt activation. Fully activated AKt regulates cell proliferation and apoptosis through its upstream and downstream regulation. Dysregulation of the PI3K signaling pathway is involved in almost all human cancers. PIK3CA (encoding the PI3K catalytic subunit a) is one of the most commonly mutated oncogenes in human tumors. Mutations in the oncogene PIK3CA have been found in about 2-5% of human solid tumors, with mutation rates of about 32%, 27%, 25%, 8%, and 4% in colon, glioblastoma, gastric, breast, and lung cancers, respectively, and 11% in esophageal squamous carcinoma and 6% in esophageal adenocarcinoma, among other gastrointestinal tumors.

Effect Example IC₅₀ of PI3Kα and PI3KαH1047R enzyme activity inhibition evaluation assay

The ADP-Glo Kinase Assay Kit was used for the experiments. The following buffer solutions were prepared: 50 mM HEPES, pH 7.5, 3 mM MgCl₂, 1 mM EGTA, 100 mM NaCl, 0.03% CHAPS, 2 mM DTT. The tested compound samples were dissolved in DMSO and added to the screening system at a certain starting concentration of, for example, 10 μM, diluted 3-fold, while setting a DMSO control and an unkinase control. The optimal concentrations of Pd3Kα, PI3Kα H1047R, substrate (PIIP2) and ATP were prepared with buffers. The enzyme reaction system included: buffer, ATP 25 μM, kinase substrate (PIP2, 50 μg/mL), kinase PI3Kα (0.15 μg/mL), PI3Kδ H1047R (0.05 g/mL), etc. The reaction system was reacted at room temperature for 1 hour, then terminated by adding a terminal reagent (ADP-Glo reagent, 5 μL), and the ADP content in the system was detected using a detection reagent (Kinase Detection Reagent, 10 μL). Signal data was collected using the Envision instrument. Calculated the % inhibition according to the following formula: % inhibition=(DMSO control signal value−sample signal value)! (DMSO control signal value −unkinase control signal value). Inhibition curves were plotted using the formula Y=Bottom+(Top-Bottom)/(1+(IC₅₀/X){circumflex over ( )}HillSlope) to obtain IC₅₀ values and the results are shown in Table 1.
