Description
Technical Field
The invention belongs to the technical field of biological medicines, and relates to a pyrimido-heterocyclic compound, a pharmaceutical composition containing the pyrimido-heterocyclic compound and application of the pyrimido-heterocyclic compound.
Background
The Ras gene is an important protooncogene, and is named after the finding in rat sarcoma virus. The ras gene family has three characteristic genes associated with human tumors, namely H-ras, K-ras and N-ras, which are located on chromosomes 11, 12 and 1, respectively, the former two are transforming genes of rat sarcoma virus isolated from human neuroblastoma.
The Ras protein encoded by the Ras gene has a relative molecular mass of 2.1KDa, is positioned on the inner side of a cell membrane and consists of 188 or 189 amino acids. Ras proteins include two conformations: the active GTP binding conformation and the inactive GDP binding conformation can be mutually transformed, and the Ras protein regulates and controls a plurality of signal paths including RAF-MEK-ERK, PI3K/Akt/mTOR and the like by switching between two active states, thereby regulating and controlling functions of cells such as growth, survival, migration, differentiation and the like.
RAS point mutations occur at codons 12, 13 and 61. Following RAS gene mutation, RAS exchanges with GDP/GTP at an increased frequency, RAS binds to GDP for a long period of time, resulting in RAS signaling in a sustained activation state, and uncontrolled cell proliferation, so overactivated RAS signaling can ultimately lead to cancer. RAS gene mutations are found in about one third of human malignancies. The most common oncogenic mutation in the Ras family is the KRAS mutation (85%), whereas oncogenic mutations in NRAS (12%) and HRAS (3%) family members are less common.
KRAS mutations are prevalent in a variety of cancers: including pancreatic cancer (95%), colorectal cancer (45%), and lung cancer (25%).
KRAS mutations include G12C, G12D, G12V and the like, G12D mutations are in pancreatic cancer (25%) colorectal cancer (13.3%), non-small cell lung cancer (4.1%) and small cell lung cancer (1.7%), at present, KRAS G12C mutation drug research has made better progress, a plurality of KRAS G12C inhibitors including AMG-510, MRTX-849 and the like enter clinical tests, and better treatment effect and safety are shown clinically, but KRAS G12D mutation tumors have no effective treatment means, and have larger clinical requirements. Therefore, the development of the high-activity inhibitor aiming at the KRAS G12D mutation has the potential of treating various cancers and has wide market prospect.

AGS cells are planted in a transparent 96-hole cell culture plate, each hole contains 10000 AGS cells in 80 mu L cell suspension, the cell plate is placed in a carbon dioxide incubator and incubated at 37 ℃ overnight;
after overnight cell culture, the cell culture medium was removed and serum-starved overnight with the addition of serum-free medium.
The test compound was diluted to 2mM with 100% DMSO as a first concentration, and then diluted 5-fold with a pipette to the 8 th concentration, i.e., from 2mM to 0.026. Mu.M. Adding 2 mu L of compound into 78 mu L of cell starvation culture medium, mixing uniformly, adding 20 mu L of compound solution into a hole of a corresponding cell plate, putting the cell plate back into a carbon dioxide incubator, and continuing incubation for 1 hour, wherein the concentration of the compound is 10 mu M-0.128nM, and the concentration of DMSO is 0.5%;
after the incubation is finished, removing cell supernatant, adding 50 mu L of cell lysate into each hole, and incubating for 30 minutes at room temperature by shaking;
diluting Eu-labeled ERK1/2 phosphorylation antibody and d 2-labeled ERK1/2 phosphorylation antibody by 20 times by using detection solution; taking 16 mu L of cell lysate supernatant, putting each well into a new 384 white microplate, adding 2 mu L of Eu-labeled ERK1/2 phosphorylated antibody diluent and 2 mu L d-labeled ERK1/2 phosphorylated antibody diluent, and incubating for 4 hours at normal temperature;
after the incubation was completed, the HTRF excitation was read at 320nm, emission at 615nm,665nm using a multi-label analyzer.
And (3) data analysis:
the original data were converted to inhibition using the equation (Sample-Min)/(Max-Min) 100%, and the IC50 values were obtained by curve fitting with four parameters (log (inhibitor) vs. response — Variable slope mode in GraphPad Prism). Table 1 provides the inhibition of p-ERK by the compounds of the present invention. Wherein A represents the activity data less than 1uM, B represents the activity data between 1uM and 10uM, and C represents the activity data more than 10uM, and the specific experimental results are shown in Table 1.
