Abstract
Description
Technical Field
[0001] The present invention belongs to the field of biopharmaceuticals, and particularly relates to a compound for targeted degradation of ALK protein, a preparation method thereof, and an application thereof. Background Art
[0002] Anaplastic lymphoma kinase (ALK) is a transmembrane protein tyrosine kinase belonging to the insulin receptor kinase subfamily. It was first discovered in anaplastic large cell lymphoma (ALCL) with a nucleophosmin (NPM)-ALK fusion form, which is a subtype of T-cell non-Hodgkin lymphoma and is usually associated with chromosomal translocation. Since then, many cancers have been successively found to be related to different forms of ALK fusion, including non-small cell lung cancer (NSCLC, EML4-ALK), inflammatory myofibroblastic tumor (IMT, TPM3-ALK), and diffuse large B-cell lymphoma (DLBCL, CLTC-ALK). In addition, gene amplification of ALK and wild-type ALK protein mutations have been reported in a variety of tumors (such as EML4-ALK fusion, F1174L mutation, etc.).
[0003] ALK has become an attractive therapeutic target, partly because its level in normal adult tissues is low, which is considered to reduce the chance of off-target toxicity caused by ALK inhibitors. Therefore, therapeutic strategies that inhibit ALK kinase activity are considered to produce fewer side effects. So far, the US Food and Drug Administration (FDA) has approved 5 ALK small molecule inhibitors, including the first-generation inhibitor Crizotinib, the second-generation inhibitors Alectinib, Ceritinib, and Brigatinib, and the third-generation inhibitor Lorlatinib for the treatment of ALK-positive NSCLC patients. To achieve continuous ALK inhibition, the inhibitor must bind to the ALK protein for a long time to reach binding saturation. During this process, off-target effects and kinase mutations may occur, and abnormal proteins cannot be cleared, resulting in drug resistance, which becomes a major obstacle to clinical efficacy. Drug resistance to ALK inhibition remains a severe challenge. Therefore, there is an urgent need to develop new ALK drugs and alternative ALK-targeted methods to overcome drug resistance.
[0004] Targeted protein degradation (TPD) technology mainly uses small molecules to induce ubiquitination of target proteins through the ubiquitin-proteasome system and then rapidly degrade pathogenic target proteins to produce therapeutic effects. TPD is expected to treat a variety of diseases, including cancer, infection, inflammation, and neurodegenerative diseases. Compared with small molecule inhibitors, degraders have many advantages, including enhanced selectivity, the ability to overcome drug resistance, targeting undruggable proteins, and eliminating the entire protein (rather than just inhibiting enzyme function). In recent years, with the continuous development of protein degradation technology, TPD has been widely used in the development of therapeutic drugs for various diseases, and some ALK protein degraders have been reported one after another. Unfortunately, the currently reported ALK degraders generally have limitations such as low specificity, poor oral in vivo anti-tumor efficacy, and inability to penetrate the brain, and cannot produce clinical value. There is an urgent need to develop ALK degraders with high oral bioavailability, brain penetration, and high specificity. Summary of the Invention
