Pyrimido cycle compound and its preparation method and application
Technical field
The invention discloses pyrimido cycle compound, its pharmaceutically acceptable salt and its solvates.The present invention also mentions
It supplied the preparation method of such compound, prepared treatment and SHP2 containing the composition of such compound and such compound
Purposes in terms of the drug of active exception related disease or illness.
Background technique
Tyrosine phosphatase SHP2 is by two homologous 2 structural domains of the end N- Src (N-SH2 and C-SH2) and an albumen junket
Propylhomoserin phosphatase catalytic structural domain (PTP) is constituted.Under base state, N-SH2 can form a cyclic annular knot in conjunction with PTP
Structure, so that the combination of PTP and substrate is hindered, so that enzymatic activity is suppressed;When the tyrosine of upstream receptor protein is by phosphoric acid
After change, N-SH2 is in conjunction, and PTP catalytic domain is released to play phosphatase activity.
On a cellular level, SHP2 is participated in by the function in the cytoplasm downstream of many receptor tyrosine kinases
Multiple tumour cell signal transduction pathway, such as RTK/Ras/MAPK, JAK/STAT and PI3K/Akt.By to these kinases with
And the regulating and controlling effect of signal path, SHP2 and many important cell activities are closely related, such as cell Proliferation, migration, divide
Change, the dead, regulation of cell factor and tumour generation etc..
Meanwhile SHP2 also assists in the immune system inhibition of programmed death receptor 1 (PD1) mediation.The PD-1 of T cell with
After PD-L1 is combined, it can do recruit a large amount of SHP2 in the cell.SHP2 can be by T cell endoantigen receptor pathway albumen dephosphorization
Acidification, to inhibit the activation of T cell.Therefore, immunosupress can be reversed in tumor microenvironment by inhibiting the activity of SHP2.
SHP2 is important a member in Protein-tyrosine-phosphatase family, related to a variety of diseases of the mankind, such as exerts southern synthesis
Levy (Noonan Syndrome), leopard syndrome (Leopard Syndrome), teenager's myelomonocytic leukemia, at nerve
Cytoma, melanoma, acute myeloid leukaemia, breast cancer, cancer of the esophagus, lung cancer, colon cancer, head cancer, neuroblastoma, head
Squamous cell carcinoma, gastric cancer, primary cutaneous type and spongioblastoma of neck etc..
A series of patents delivered at no distant date, such as WO2018/013597A1, WO2017/210134A1, WO2017/
211303A1、WO 2017/216706A1、WO 2016/203406A1、WO 2016/203405A1、WO 2016/203404A1、
It is novel as one to show SHP2 by WO2015/107495A1, WO2015/107494A1 and WO2015/107493A1 etc.
Can patent medicine target spot, cause more and more concerns.Around the exploitation of SHP2 inhibitor, there is the PTP catalysis region for SHP2
Inhibitor exploitation and non-catalytic regions the big strategy of allosteric inhibitor exploitation two;Since PTP catalysis region inhibitor has selection
Property and druggability difference problem, more researchs tend to the exploitation of allosteric inhibitor at present.Above-mentioned patent disclosure is allosteric
Inhibit, but most of, such as WO 2015/107493 A1 disclosed in compound SHP099s not high to the inhibitory activity of tumour cell
(6- (4- amino -4- methyl piperidine -1- base) -3- (2,3- dichlorophenyl) pyrazine -2- amine) etc., up for further development structure
SHP2 inhibitor novel and that bioactivity is good, druggability is high.

Compound powder, which is dissolved in DMSO, is made mother liquor.When experiment, it is dilute that compound storage solution with DMSO carries out 3- times of gradient
It releases, 10 different test concentrations are arranged in same compound.Take the compound of 1 each concentration point of μ L to detection plate (Corning,
Costar 3915) in hole, each concentration point is arranged 2 and parallel repeats.Albumen used is the active egg of the 76th amino acids mutation
White SHP2E76A, substrate used is DiFMUP (Invitrogen, E12020).SHP2E76AAlbumen and substrate use buffer respectively
(0.1M NaAc (pH 7.2), 0.02%Tween 20,0.1%BSA, 1mM EDTA, 5mM DTT) is diluted to 1.2nM and 20 μ
M.50 μ L enzyme solutions are added into detection hole, add 50 μ L substrates therewith.In Spectra max i3 (Molecular
Devices) on instrument, every 1 minute record (Ex 358nm/Em 455nm) first order fluorescence signal, the product of product is calculated with this
Rate is tired out to characterize enzymatic activity.Nonlinear regression analysis is carried out with GraphPad Prism 5, passes through Y=Bottom+ (Top-
Bottom)/(1+10^ ((LogIC50-X) * HillSlope)) equation model goes out the curve that enzymatic activity changes with compound concentration.
Acquire the IC of each compound50Value.
As a result
Following table shows the IC of part of compounds of the present invention50Value.
Alphabetical A represents IC50Less than 100nM;
Letter b represents IC50For 100nM to 1000nM;
Embodiment 126: phosphorylated protein kinase (p-ERK) cell experiment
Inhibit the phosphorylation level of intracellular protein kinase (ERK) by AlphaLISA method detection compound.
First step compound handles cell.Untested compound first carries out 3- times with 100%DMSO and dilutes, and 9 are arranged altogether not
Same concentration gradient;Then MOLM13 cell is inoculated with to 96 orifice plates, every 100 μ L of pore volume with 30000, every hole cell density;With
Every hole is separately added into the DMSO of 0.5 μ L or the untested compound of various concentration afterwards, and 2 repetitions are arranged in each concentration, DMSO's
Final concentration is controlled 0.5%.
Second step lytic cell.After cell is handled 2 hours, culture medium is removed, phosphate buffered saline solution washs cell 3
Secondary, the lysis buffer of the 50 fresh configurations of μ l is added in every hole, shakes and is placed at room temperature for 10 minutes.
Third stepUltraTMP-ERK 1/2 (Thr202/Tyr204) kit
(Perkin Elmer, ALSU-PERK-A10K)) detection phosphorilated extracellular signal-regulated kinase (p-ERK).Take 10 μ l's
Above-mentioned lysate is to 384 orifice plates (Perkin Elmer, 6005350), according to the extracellular signal of product description test sample
Adjust the phosphorylation level of kinases.It is detected using the AlphaScreen on Spectra max i3 (Molecular Devices)
Device reads signal.Percentage (%) is inhibited to be calculated by the following formula acquisition:
Inhibit percentage (%)=(the p-ERK signal of 1- compound processing cell/DMSO processing cell p-ERK letter
Number) * 100 results
Following table shows the IC of part of compounds of the present invention50Value.
Alphabetical A represents IC50Less than 100nM;
Letter b represents IC50For 100nM to 1000nM;
Embodiment 127:MOLM-13 cell proliferation experiment
It is suspended in culture medium (RPMI-1640 contains 10%FBS and 1%Penicillin-Streptomycin, Gibco)
MOLM-13 cell be inoculated on 384 orifice plates with 800 cells (40 hole μ L/).Cell is immediately at untested compound
Reason, compound concentration is respectively 50,16.67,5.56,1.85,0.617,0.206,0.069,0.023,0.0076 μ Μ.3 days
Afterwards, the CellTiter-Glo reagent (Promega, ZG7572) of 5 μ L of every hole addition, room temperature avoid light place 10 minutes.Pass through
Spectra max i3 (Molecular Devices) detects fluorescence signal.The relative growth rate of processing cell is compareed with DMSO
It is compared.
As a result
Following table shows the IC of part of compounds of the present invention50Value.
Alphabetical A represents IC50Less than 100nM;
Letter b represents IC50For 100nM to 1000nM;
According to phosphorylated protein kinase described in the experiment of SHP2 inhibition of enzyme activity described in embodiment 125, embodiment 126
(p-ERK) the identical test method of MOLM-13 cell proliferation experiment described in cell experiment and embodiment 127, applicant are directed to
2015/107493 A1 of WO or document (Nature 2016,535,148-152) disclosed compound SHP099 (6- (4- amino-
4- methyl piperidine -1- base) -3- (2,3- dichlorophenyl) pyrazine -2- amine) corresponding experiment has been carried out, this hair is listed in following table
The comparative experimental data of compound and SHP099 obtained by bright section Example, by being found after comparison, pyrimidine of the present invention
And cycle compound has more superior activity.
