Description

Pyrrolo pyrimidine compound and preparation method, pharmaceutical composition and application thereof
Technical Field
The invention belongs to the field of chemical drugs, and particularly relates to a pyrrolopyrimidine compound, a preparation method thereof, a pharmaceutical composition and application thereof in inhibition of deubiquitinase USP 51.
Background
Malignant tumor is one of the major diseases threatening the life safety of human beings. At present, the treatment means of malignant tumors mainly comprise: surgery, radiation therapy, chemotherapy, and the like. The traditional antitumor drug has the defect of large toxic and side effects and the like, so that the traditional antitumor drug is prevented from being further applied in clinic. A number of studies have shown that deubiquitinase exerts vital physiological functions by modulating protein interactions, localization and enzymatic activity, thereby affecting cellular processes including transcription, DNA damage signaling and DNA repair, cell cycle progression, oxidative stress, apoptosis, etc. It has a close relationship with the development of tumor. Deubiquitinase inhibitors have also been found to exert significant antitumor effects in various preclinical studies of tumors, and have become a hotspot in the development of new antitumor drug fields.
Epithelial-mesenchymal transition (EMT) and its reversal processes and mesenchymal-epithelial transition (MET) play a key role in tumor metastasis. During EMT, epithelial cells lose the adhesive and tight junctions that remain in close association with neighboring cells. Activation of EMT by multiple transcription factors can induce migration, invasion and metastasis of tumor cells. While ZEB1 is a transcription factor for controlling EMT induction, and can promote tumor invasion, metastasis and drug resistance treatment. In many cancer types, aberrant expression of ZEB1 is associated with invasive behavior, high tumor index, drug resistance, high metabolic plasticity and metastasis. For example, in breast cancer patients, ZEB1 overexpression was found to occur in tumor cells of triple negative/basal-like breast cancer.
USP51 is a deubiquitinase of ZEB1 (Zinc Finger E-Box Binding Homeobox 1), and targeting US P51 is also likely to be an alternative approach to targeting the pro-cancerous transcription factor ZEB 1. USP51 was found to be a ubiquitin enzyme that binds, de-ubiquitinates and stabilizes ZEB1 by screening a library of human de-ubiquitin enzymes. The absence of USP51 in stromal-like breast cancer cells results in down-regulation of ZEB1 protein and interstitial markers, up-regulation of cadherin-E, and inhibition of cell invasion. In contrast, USP51 overexpression in epithelial cells resulted in upregulation of ZEB1 and mesenchymal markers. Furthermore, USP51 was able to regulate the expression of ZEB1 target genes. Importantly, USP51 is overexpressed in breast cancer patients and is associated with poor survival.
The development of the USP family inhibitor is mainly aimed at targets such as USP7, USP1, USP9 and the like of hot spots. USP51 has been less frequently studied and reported as a newer deubiquitinase for its protease itself and its inhibitors. And the selective inhibitors of deubiquitinase developed at present still have a plurality of problems: (1) related studies on deubiquitinase have focused on USP family members, particularly USP7, but most inhibitors reported thereto exhibit weaker inhibitory activity or contain poor chemical characteristics or have poor selectivity for the currently known deubiquitinase family. (2) At present, the understanding of the structure and functional substrates of the deubiquitinase protein is insufficient and unbalanced, and the inherent mechanism related to the deubiquitinase and tumorigenesis still lacks exploratory knowledge. This also results in the disadvantages of poor specificity of the current small molecule inhibitors of most deubiquitinating enzymes. In addition, the original inhibitor screening method and technology have the defects of poor compatibility with the actual physiological environment, easy occurrence of false positive and the like. Therefore, the targeted USP51 small molecule inhibitor which has novel structure, high inhibition activity, high selectivity and high stability is researched and designed to be synthesized, and has important scientific significance.
