Description
Technical Field
The invention relates to the field of medicines, in particular to an EZH2 covalent irreversible inhibitor, a preparation method and application thereof.
Background
In eukaryotes, post-translational modifications of histones (such as methylation, acetylation, phosphorylation and ubiquitination) are critical for regulating chromatin structure and gene transcription. Among them, histone lysine methyltransferase EZH2, as a catalytic component of Polycomb inhibitory complex 2 (PRC 2), can inhibit the expression of a target gene by catalyzing trimethylation of lysine 27 of histone H3. In recent years, the research finds that EZH2 is highly expressed in various human solid tumors, and also has gain-of-function mutation in blood tumors such as non-Hodgkin lymphoma, melanoma and the like, so that the expression level of H3K27Me3 in a patient is increased, and the generation and development of tumors are promoted. Therefore, the development of EZH2 inhibitors has been a hot spot in the frontier of research on antitumor drugs.
Over the course of several years of effort, several EZH2 inhibitors were sequentially entered into clinical study sessions, including Tazemetostat, GSK126, CPI1209, CPI0209, SHR2554, PF06821497, DS3201b, and HH2853, among others. Of these, Tazemetostat, approved by the FDA for the treatment of metastatic/locally advanced epithelioid sarcoma adult patients who fail to resect completely and pediatric patients over 16 years of age, is the FDA-approved first drug for treatment of epithelioid sarcoma and also the first approved EZH2 inhibitor. However, the EZH2 inhibitors including Tazemetostat currently in clinical research are all non-covalent reversible inhibitors, and have the defects of large administration dosage, low drug effect and the like. For example, the clinically recommended amount of Tazemetostat is 800mg twice daily. Therefore, the development of an EZH2 inhibitor with a novel action mechanism is urgently needed, and the defect of low drug effect of a clinically researched drug is overcome.
Unlike non-covalent inhibitors, electrophilic active groups (commonly called warheads) of covalent inhibitors can form covalent structures with nucleophilic amino acid residues (such as cysteine) of target proteins, so that the covalent inhibitors have the advantages of long action time with targets, strong drug effect and the like. The covalent inhibitor developed by targeting EZH2 is expected to improve the dilemma that the non-covalent inhibitor is not good in drug effect in clinical research at present, and is beneficial to developing a new generation EZH2 inhibitor with strong drug effect and good drug success.
Analysis of the eutectic structure of the non-covalent inhibitor of EZH2 with the target protein (e.g., PDB ID: 5LS6, Journal of Medicinal chemistry 2016,59,9928-Suitable as sites for covalent binding for the development of covalent inhibitors. Based on the design, the EZH2 covalent inhibitor with the characteristics of strong drug effect and drug success has important research significance and application value.

Test method
HTRF method:
the technique combines two techniques of Fluorescence Resonance Energy Transfer (FRET) and Time Resolved Fluorescence (TRF). This technique uses XL665 as a Donor (Donor) and a chelate label of Eu element having a cryptate structure, and is based on Fluorescence Resonance Energy Transfer (FRET) between the Donor and an acceptor (second fluorescent label) of Eu cryptate. When the two fluorophores are close due to the interaction of the biomolecules, part of the energy captured by the cryptate is released when excited, and the emission wavelength is 620 nm; another part of the energy is transferred to the acceptor (acceptor) with an emission wavelength of 665 nm. The emission at 665nm is generated only by FRET by the donor (donor). Therefore, when biomolecules interact, there are two excitation lights 620nm and 665 nm; when there is no interaction, there is only 620nm excitation light.
Enzyme reaction:
1. enzyme reaction buffer (1 ×): 50mM Tris-HCl, pH 8.8,10mM NaCl,4mM DTT,4mM MgCl2,0.01%Tween20.

L H3(1-50) K27me 1-biotin peptide/SAM mixture (2.5X). Cover the reaction kettle and incubate for 4h at room temperature in the dark.
Each experiment is provided with two pairs of holes, and a positive control group and a negative control group
And (3) detection:
1. prepare 2 times of final concentration provided by anti-H3K27 me3-Eu (K) product instruction and 100nM SA-XL665 with 1 XDeprotection Buffer, mix them into mixed solution (2X), add 10. mu.L of mixed solution into each well, incubate for 60min at room temperature in the dark.
2. The cover was opened and the emitted wavelengths of light at 620nm and 665nm were detected with an HTRF compatible reader.
And (4) analyzing results:
the fluorescence intensity value of the sample well measured at 665nm was F1, the fluorescence intensity value of the sample well measured at 620nm was F2, the fluorescence intensity value of the positive control at 665nm was a1, the fluorescence intensity value at 620nm was a2, the fluorescence intensity value of the negative control at 665nm was B1, and the fluorescence intensity value at 620nm was B2.

Test example three: compound 34, 37 and EPZ6438 cell proliferation inhibition assay
The purpose of the test is as follows: evaluation of the Effect of test Compounds on the proliferative Effect of different cell lines
Test cell lines: pfeiffer, KAPRAS-422, RL, SU-DHL-10, HT, KAPRAS-1106P, WLL-1, SU-DHL-2, U2932, DB, WSU-DLCL2, OPM-2
The rest of the test examples are the same as the second test example
The results of the assays for inhibition of various cellular activities by compounds 34, 37 of the invention and the positive control EPZ6438 are shown in figure 1.
As shown in FIG. 1, compounds 34 and 37 have strong cell killing ability on Pfeiffer, KAPRAS-422, RL, SU-DHL-10, HT and other cell lines, and are stronger than positive control drug EPZ 6438. Among them, compound 34 had potent cell proliferation inhibitory effect on HT cell line containing WT EZH2, but positive control EPZ6438 did not, indicating that EZH2 covalent inhibitor 34 has stronger cell proliferation inhibitory ability and wider cell proliferation inhibitory range than EPZ 6438.
Test example four: covalent verification test for Compound 34 and Compound 37-SAM Competition test
The experimental basis is as follows:
the positive control EPZ6438 is a non-covalent reversible inhibitor of EZH2 and is in a competitive relationship with the cofactor SAM, the IC of which is measured in the enzyme activity assay50The values decreased with increasing SAM concentration (Proc Natl Acad Sci USA.2013, 110, 7922-. The Cys663 of the target EZH2 protein is developed into a covalent inhibitor which can generate Michael addition reaction with the protein to generate covalent bonds and irreversibly occupy a drug binding pocket, so the covalent inhibitor does not have a competitive relationship with a cofactor SAM, and is particularly represented as enzyme activity IC of the covalent inhibitor50The value does not decrease with increasing SAM concentration.
As shown in FIG. 2, IC's for Compounds 34 and 3750As SAM concentration increased and remained unchanged, it exhibited completely different kinetic properties from EPZ6438, thereby verifying that compounds 34 and 37 are covalent irreversible inhibitors of EZH 2.
It should be finally noted that the above examples are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and that other variations and modifications based on the above description and thought may be made by those skilled in the art, and that all embodiments need not be exhaustive.
