Abstract
Description
[Technical Field]
[0001] The present invention relates to compounds that degrade target proteins based on chaperone-mediated protein degradation (CMPD) technology, as well as methods for producing the same and uses thereof. [Background technology]
[0002] Cancer remains one of the most elusive diseases since the first therapeutic agents were developed in the 1940s. As cancer treatment technology advances, the form of anticancer drugs is also changing. Approximately 40% of new drug R&D investments are focused on anticancer drugs, and many new anticancer drugs have been released. However, unmet demand among cancer patients remains. The current direction of anticancer drug development is to develop new anticancer drugs that overcome resistance or improve therapeutic response rates. Existing anticancer drugs rely on existing technologies, such as small molecule compounds and antibodies. Only 400 of the approximately 3,000 disease-causing genes have been approved for treatment (85% of targets are undruggable). Even drugs developed for cancer treatment have issues with side effects, resistance, and response rates, making the introduction of next-generation drugs and technologies crucial.
[0003] Due to the limitations of existing drug development technologies that focus on inhibiting the function of disease-related proteins, "targeted protein degradation technology (PDT)" has emerged as a new strategy to overcome these challenges. Targeted protein degradation is a novel concept that selectively degrades proteins and removes disease-related proteins themselves. Chemically induced targeted protein degradation is a novel method for the drug development of small molecule compounds. Small molecule compounds promote the interaction of various cellular protein degradation pathway components with target proteins or proteins, and are used as a disease treatment method to induce the degradation of the target proteins or proteins. This technology can be applied to diseases that target proteins that are undruggable by existing drug development technologies. It is expected that PDT will not only degrade and essentially remove disease-causing proteins, but also overcome the side effects and resistance of previously developed drugs.
[0004] In the field of PDT, proteolysis-targeting chimeras (PROTACs), a method using E3 ligases, are a platform that utilizes small molecules to induce specific protein degradation. PROTAC molecules are bifunctional small molecules that simultaneously bind to target proteins and E3-ubiquitin ligases. Therefore, PROTAC molecules trigger polyubiquitination and subsequent degradation of the target protein by the proteasome. PROTAC molecules have good tissue distribution and the ability to target intracellular proteins. However, PROTAC molecules face the problem of resistance to PROTACs through E3 ligase mutations. Therefore, PROTAC technology requires the discovery of novel E3 ligases that are suitable for targeting new proteins with specific substrate specificity.
[0005] On the other hand, the CMPD technology of the present invention overcomes the limitations of existing PROTAC technology by promoting and inducing protein degradation in vivo through the ubiquitin proteasome system (UPS pathway) via interactions with various E3 ligases, rather than through the direct involvement of E3 ligases, via a chaperone complex.
[0006] In addition, when a disease-related target protein is a client protein of a chaperone complex, it can be selectively targeted for degradation, which allows for a wider range of target proteins and greater scalability compared to PROTACs. This makes it possible to study a variety of diseases, including cancer, degenerative brain diseases, and rare diseases, and also facilitates pipeline scalability.
[0007] Lung cancer is a common cancer worldwide and a leading cause of cancer-related deaths. While the five-year survival rate has improved since the 2000s, it still remains at 28.2%. In cases involving distant metastasis, the observed survival rate in Korea is a very low 6.1%. Non-small cell lung cancer (NSCLC) is a cancer characterized by a variety of genetic mutations. Despite the development of numerous treatments, there remains significant unmet need. This has led to various research efforts, including the development of treatments targeting resistance mutations and combination therapy. Approximately 30% of all NSCLC patients are diagnosed with epidermal growth factor receptor (EGFR) mutations. The market for treatments targeting this disease has focused on first-generation EGFR inhibitors and second-generation treatments for the EGFR T790M mutation, which develops as a result of resistance to first-generation treatments. Among all non-small cell lung cancer patients, those with c-MET (hepatocyte growth factor receptor) mutations account for 6% and are an uncommon type. However, there are approximately 250,000 patients with c-MET mutations, which are the main cause of resistance after first- and second-generation EGFR therapies. As a result, expectations and demand for MET-targeted therapeutic agents are increasing in the non-small cell lung cancer treatment market.
[0008] The present invention provides a new alternative to targeted protein degradation in MET-mutated non-small cell lung cancer disease through the development of CMPD-based drugs targeting the MET protein.
[0009] The present inventors designed the structure of CMPD drugs by using various linkers to CMPD-derived compounds, which are binding moieties of chaperone complex-associated proteins, and existing target drugs (e.g., crizotinib, capmatinib, tepotinib, etc.) as target-binding substances. As a result, we found that MET, a major target protein of interest in non-small cell lung cancer, can be degraded and removed at its source by CMPD, and that this can be expected to have superior anticancer effects compared to existing anticancer drugs due to the complete degradation of the target protein MET. This led to the completion of the present invention. Summary of the Invention [Problem to be solved by the invention]

After 3 days, the medium is removed, and 10 μl of CCK8 reagent + 90 μl of medium is added to each well. After 3 to 4 hours of incubation, the absorbance is measured using an ELISA reader at a wavelength of 450 nM. IC was calculated using the Graphpad Prism program. 50 The values were derived and are shown in Table 2.
[0078] As can be seen from Table 2, the cell viability of each of the compounds prepared in Examples 1 to 11 was approximately 10 times higher than that of the control drug crizotinib, intermediate compound (d) of the first moiety that binds to the chaperone complex, and compound (i).
[0079] Therefore, the compound of the present invention has a much superior anti-cancer effect compared to the compound having the first moiety and the second moiety.
[0080] [Table 2]
[0081] <Experimental Example 2> Confirmation of c-MET degradation effect In this experiment, cells were treated with each of the compounds prepared in Examples 1 to 11, and the tendency and degree of degradation of the target protein c-MET (total form) itself in the cells was evaluated.
[0082] <Experimental Method> Test to confirm degradation of target protein 5 x 10 cells (H596 or H1437 cells) in a Φ60 culture dish or Φ100 culture dish 5 or 1 x 10 6After seeding, the cells were cultured for at least 12 hours. After removing the medium, the cells were treated with each of the compounds prepared in Examples 1-11 according to the conditions, i.e., concentration (0, 2.5, 5, 10 μM), time (0, 6, 8, 24, 48, 72 hours), or the same constant concentration and time (5 μM, 72 hours) for all compounds. Cells were then harvested and lysed using RIPA buffer. After centrifugation (4°C, 13,000 rpm, 15 min), the supernatant was transferred to a new tube. Protein was quantified using a Bradford assay, and the loading sample was prepared by boiling at 95°C and subjected to Western blotting. The sample was loaded onto an 8% SDS polyacrylamide gel and electrophoresed at 80 V, then switched to 100–120 V (when the loaded sample migrated from the stacking gel to the running gel). The electrophoresed polyacrylamide gel was transferred to a membrane (transfer buffer was diluted with 10X transfer buffer:methanol:DW = 1:2:7, and then incubated at 100 V for 1 hour or 80 V for 2 hours in cold conditions). The membrane was then blocked with 5% skim milk for 30 minutes and washed with PBS-T (phosphate-buffered saline with Tween 20). The membrane was incubated with a primary antibody diluted in 5% BSA + NaN3 solution for at least 12 hours, then washed with PBS-T and incubated with 5% skim milk + secondary antibody for 1 hour and 30 minutes. After washing with PBS-T, the membrane was reacted with ECL solution, and the bands were detected using an imaging device to confirm the degradation of the band corresponding to the target protein c-MET. The results are shown in Table 3 and Figures 1 to 6.
[0083] As can be seen from Table 3 below, crizotinib, compound (d) having a first moiety that binds to the chaperone complex, and compound (i) did not show any degradation of the target MET protein, whereas each of the compounds prepared in Examples 1 to 11 clearly showed degradation of the target protein.
[0084] Therefore, the present invention has an extremely excellent decomposition efficiency for the target protein.
[0085] [Table 3] <Experimental Example 3> Target protein degradation and recovery by the UPS pathway In this experiment, each of the compounds prepared in Examples 1 to 11 was treated simultaneously with the proteasome inhibitor bortezomib to evaluate the degradation and recovery of target proteins via the ubiquitin-proteasome system (UPS) pathway.
[0086] <Experimental Method> Target protein degradation and recovery confirmation test 3 x 10 H596 or H1437 cells were cultured in a 6-well culture plate. 5After seeding, the cells were cultured for at least 12 hours. After changing the medium, 100 nM bortezomib and 5 μM of each compound prepared in Examples 1 to 11 were treated together. A control group was treated with the same volume of dimethylsulfoxide (DMSO), the drug solvent. After 16 hours, the medium was removed, the cells were washed with phosphate-buffered saline (PBS), and harvested using trypsin-ethylenediaminetetraacetic acid (Trypsin-EDTA). Cell lysis was performed with RIPA buffer (Radio-ImmunoPrecipitation Assay buffer), centrifuged (4°C, 13,000 rpm, 15 min), and the supernatant was transferred to a new tube. Protein quantification was performed using the Bradford assay, followed by boiling at 95°C for 10 minutes. Western blotting is performed on an 8% SDS polyacrylamide gel (sodium dodecyl sulfate polyacrylamide gel) at 80V. Once proteins have migrated from the stacking gel to the running gel, the voltage is changed to 100V and the gel is left cold for 60 minutes. The gel is then blocked with 5% skim milk for at least 30 minutes and washed with PBS-T (phosphate-buffered saline with Tween 20). The primary antibody is diluted in 5% bovine serum albumin (5% BSA) and NaN3 solution and incubated for at least 12 hours. After washing with PBS-T, the secondary antibody is diluted in 5% skim milk and incubated for 1 hour and 30 minutes. After washing with PBS-T, the membrane is incubated with ECL solution and the bands are confirmed using an imaging device. The results are shown in Table 4 and Figures 7 to 12 to confirm whether the reduction in MET expression caused by each of the compounds prepared in Examples 1 to 11 was restored when treated with bortezomib.
[0087] As can be seen from Table 4, crizotinib, intermediate compound (d) of the first moiety that binds to the chaperone complex, and compound (i) did not show degradation or recovery of the target MET protein. On the other hand, each of the compounds prepared in Examples 1 to 11 clearly showed degradation of the target protein and recovery of the target protein upon treatment with the proteasome inhibitor bortezomib.
