Description
技术领域technical field
本发明属于医药领域,具体涉及一种靶向EGFR蛋白降解的双功能化合物及其在制备药物中的用途。The invention belongs to the field of medicine, in particular to a bifunctional compound targeting EGFR protein degradation and its use in preparing medicine.
背景技术Background technique
EGFR(Epidermal Growth Factor Receptor)是跨膜蛋白酪氨酸激酶erbB受体家族的一员。通过与其配体-例如表皮生长因子(EGF)的结合,EGFR在细胞膜上可以形成同源二聚体,或者与家族中其他的受体(比如erbB2,erbB3,或erbB4)形成异源二聚体。这些二聚体的形成,可引起EGFR细胞内关键的酪氨酸残基磷酸化,从而激活细胞内多个下游的信号通路。这些细胞内信号通路在细胞增殖、生存及抗凋亡中起重要作用。EGFR信号传导通路失调,包括配体及受体的表达增高、EGFR基因扩增以及突变等,可促进细胞向恶性转化,并在肿瘤细胞的增殖、侵袭、转移以及血管形成中起重要作用。因此EGFR被认为是抗癌药物开发的靶点。EGFR (Epidermal Growth Factor Receptor) is a member of the transmembrane protein tyrosine kinase erbB receptor family. EGFR can form homodimers on the cell membrane by binding to its ligands, such as epidermal growth factor (EGF), or heterodimers with other receptors in the family (such as erbB2, erbB3, or erbB4) . The formation of these dimers can cause phosphorylation of key tyrosine residues in EGFR cells, thereby activating multiple downstream signaling pathways in cells. These intracellular signaling pathways play important roles in cell proliferation, survival and anti-apoptosis. Dysregulation of the EGFR signaling pathway, including increased expression of ligands and receptors, EGFR gene amplification, and mutation, can promote the malignant transformation of cells and play an important role in tumor cell proliferation, invasion, metastasis, and angiogenesis. Therefore, EGFR is considered as a target for anticancer drug development.
泛素蛋白(Ubiquitin)自身由76个氨基酸残基所组成,分子量约8.5kDa,以“泛素”为名是因为它在真核生物体中广泛存在。泛素化(Ubiquitination)是指泛素分子在一系列特殊的酶作用下,将细胞内的蛋白质分类,从中选出靶蛋白分子,对靶蛋白进行特异性修饰的过程,形成靶蛋白多聚泛素链。这些特殊的酶包括泛素活化酶(E1),泛素结合酶(E2)、泛素连结酶(E3)等。泛素化与肿瘤、心血管、自身免疫等疾病的发病密切相关。泛素-蛋白酶体系统降解蛋白是蛋白质选择性降解的重要途径,可以简单地分为三个步骤:首先由一种连接酶给目标蛋白加上泛素标签,然后经过多轮泛素化后就有了多个泛素标签,多聚泛素化之后的蛋白会被一种蛋白酶体识别并被降解。通过构建双功能化合物,一头是靶向目标蛋白的结构;另一头是可以结合蛋白降解体系比如E3连结酶,中间通过合适的连接链连接,可以有效促进靶点蛋白的降解。Ubiquitin itself consists of 76 amino acid residues with a molecular weight of about 8.5kDa. It is named "ubiquitin" because it is widely present in eukaryotic organisms. Ubiquitination refers to the process in which ubiquitin molecules classify intracellular proteins under the action of a series of special enzymes, select target protein molecules, and specifically modify the target protein to form target protein polyubiquitination. prime chain. These special enzymes include ubiquitin activating enzyme (E1), ubiquitin conjugating enzyme (E2), ubiquitin ligase (E3), etc. Ubiquitination is closely related to the pathogenesis of tumors, cardiovascular, autoimmunity and other diseases. Degradation of proteins by the ubiquitin-proteasome system is an important pathway for selective protein degradation, which can be simply divided into three steps: first, a ligase adds a ubiquitin tag to the target protein, and then after multiple rounds of ubiquitination With multiple ubiquitin tags, the polyubiquitinated protein is recognized by a proteasome and degraded. By constructing a bifunctional compound, one end is a structure targeting the target protein; the other end is a protein degradation system such as E3 ligase, and the middle is connected by a suitable connecting chain, which can effectively promote the degradation of the target protein.
已上市的EGFR抑制剂药物在治疗后大多会产生对小分子抑制剂的抗药性。其耐药机制包括EGFR继发突变、旁通路激活等。目前还没有通过构建双功能化合物降解EGFR蛋白的药物上市。开发能够泛素化降解EGFR蛋白的双功能化合物可能成为一种新的治疗肿瘤或癌症的方法,具有广阔的应用前景。Most of the marketed EGFR inhibitor drugs develop resistance to small molecule inhibitors after treatment. The drug resistance mechanisms include EGFR secondary mutations, bypass pathway activation and so on. There are no drugs on the market that degrade EGFR proteins by constructing bifunctional compounds. The development of bifunctional compounds that can degrade EGFR protein by ubiquitination may become a new method for the treatment of tumors or cancers, which has broad application prospects.

After that, the medium in the cells was removed, and the cells were fixed with 4% paraformaldehyde, 150 μL per well, and incubated at room temperature for 15 min. After the cells were fixed, the cells were permeabilized with 0.1% (v/v) Triton X-100, 150 μL per well, and incubated at room temperature for 15 min. Cells were blocked with 1% blocking reagent (Roche, catalog number: 11096176001), 100 μL per well, and incubated at room temperature for 60 min. After blocking, 50 μL of EGFR antibody diluted with 1% (w/v) blocking reagent (CST, Cat. No.: 4267S, dilution ratio of 1:250) was added to each well, and incubated at room temperature for 2 hours. The EGFR antibody in the wells was removed, and the cells were washed with 0.05% (v/v) PBST, 200 μL per well, 4 times. Then add 1% (w/v) blocking reagent diluted goat anti-rabbit fluorescent secondary antibody (Invitrogen, Cat. No. A32731) and DAPI staining solution (Thermofisher, Cat.

Antibodies in the wells were then removed, and cells were washed with 0.05% (v/v) PBST, 200 μL per well, repeated 4 times (the last wash was retained in the wells). Data were acquired using a high-content imaging analysis system (GE, In CellAnalyzer, model: 2200), 9 fields of view were scanned per well, and the exposure time of the FITC channel was set to 0.5s, and the exposure time of the DAPI channel was set to 0.05s. The data were analyzed using the In cell analyzer workstation software to obtain intracellular EGFR fluorescence signal values and surrounding background values. Use Excel to perform subsequent processing on the acquired data. First, the intracellular EGFR fluorescence signal value is subtracted from the background value around the cell to obtain the normalized intracellular EGFR fluorescence signal value. Next, the relative levels of EGFR after compound treatment were calculated relative to the DMSO control (DMSO treatment counted as 100%), the relative levels of EGFR were analyzed using GraphPad Prism software, and DC 50 values and fitted curves were obtained.
实验结果表明,本发明化合物能够抑制和降解EGFR蛋白,可能成为一种靶向EGFR蛋白降解的药物。The experimental results show that the compound of the present invention can inhibit and degrade the EGFR protein, and may become a drug targeting the degradation of the EGFR protein.
