Description

Technical Field

[0001] This invention relates to the field of chemical pharmaceutical technology, specifically to a method for targeting KRAS. G12D Protein degrading agents, their preparation methods, and applications. Background Technology

[0002] KRAS G12D KRAS is a common gene mutation that frequently occurs in various cancers, including pancreatic, colorectal, and lung cancer. The KRAS gene encodes a small GTPase involved in cell signaling and proliferation regulation. The G12D mutation leads to persistent activation of the KRAS protein, thereby promoting cancer cell proliferation and survival. Although KRAS mutations play a crucial role in cancer, targeting KRAS... G12D Drug development for KRAS protein faces significant challenges. The lack of a clear drug-binding pocket makes it difficult for traditional small molecule drugs to effectively bind to and inhibit its activity. Furthermore, KRAS protein interacts tightly with other intracellular proteins and membrane structures, further increasing the complexity of drug design.

[0003] Targeted protein degradation is a novel and groundbreaking drug development strategy that utilizes inherent intracellular protein degradation pathways to directly degrade pathogenic target proteins. This novel drug form includes various types, such as PROTACs, molecular gels, LYTACs, ATACs, AbTACs, ATTECs, AUTACs, and AUTOTACs. PROTACs (Proteolysis Targeting Chimeras) are bifunctional molecules composed of a target protein ligand, a linker, and an E3 ubiquitin ligase recruitment element. Upon entering the cell, the target protein ligand in a PROTAC specifically binds to the target protein, while the E3 ligase recruitment element at the other end binds to the E3 ligase, forming a target protein-PROTAC-E3 ternary complex. The E3 ubiquitin ligase mediates ubiquitination of the target protein by the ubiquitin-conjugating enzyme E2. The polyubiquitinated target protein is then transported to the proteasome for degradation, thereby reducing the target protein level. In this process, the target protein ligand does not need to occupy the binding site for an extended period. Therefore, PROTACs can cycle multiple times within the cell to exert their effects. Based on the unique mechanism of action of PROTAC, PROTAC drugs have significant advantages in drug development for overcoming drug resistance and untreatable targets. Summary of the Invention

[0222] Example 1: NCL can be combined with MDM2

[0223] 1. Co-immunoprecipitation (Co-IP) is a classic method for studying protein-protein interactions based on the specific interaction between antibodies and antigens. Hep3B liver cancer cells were lysed with IP lysis buffer (Thermo Scientific, catalog number 87788) and incubated overnight at 4°C with an antibody against NCL. Protein A / G magnetic beads (Thermo Scientific, catalog number 88802) were added and incubated at room temperature for 2 hours by rotation. The NCL and its interacting protein complex bound to the magnetic beads were washed with IP lysis buffer (Thermo Scientific, catalog number 87788), and SDS-PAGE protein loading buffer (Beyotime, catalog number P0015) was added. The mixture was heated to 100°C and held for 10 minutes. The magnetic beads were then adsorbed using a magnetic rack, and the supernatant was transferred to a new tube. Western blotting was then performed to detect whether NCL bound MDM2. The immunoblotting procedure is as follows: Protein samples are separated by SDS-PAGE electrophoresis. The separated proteins are transferred to a PVDF membrane and blocked with TBST buffer containing 5% skim milk for 1 hour at room temperature. Then, the membrane is incubated overnight at 4°C with primary antibody MDM2 (purchased from ProteinTech, catalog number 27883-1-AP) or primary antibody NCL (purchased from Cell Signaling Technology, catalog number 14574S). After washing with TBST, the membrane is incubated with HRP-labeled secondary antibody (purchased from Ibotek, catalog number AS014) at room temperature for 1 hour. The protein bands are visualized using an enhanced chemiluminescence detection kit (purchased from Ibotek, catalog number RM00021P). Figure 1 The results of A indicate that NCL can bind to MDM2.

[0224] 2. Mix 2 μg / mL recombinant human NCL (rhNCL, purchased from ACROBiosystems, NUL-H5253) and 2 μg / mL recombinant human MDM2 (rhMDM2, purchased from R&D Systems, E3-202-050) and incubate at 4°C for 7 hours. Then add the NCL antibody and incubate overnight at 4°C. Add Protein A / G magnetic beads (purchased from Thermo Scientific, catalog number 88802) and incubate at room temperature by rotation for 1.5 hours. Wash the magnetic beads three times with TBST buffer, add SDS-PAGE protein loading buffer (purchased from Beyotime, catalog number P0015), and heat to 100°C for 10 minutes. Adsorb the magnetic beads using a magnetic rack and collect the supernatant into a new tube. Then perform an immunoblotting assay to detect whether NCL binds to MDM2. Figure 1 The results of B indicate that NCL can bind to MDM2.

[0234]

[0238]

[0239] Under N2, EDCI (1.56 g, 8.16 mmol) and DMAP (1 g, 8.16 mmol) were added to a DMF (10 mL) solution of compound 2 (1.1 g, 2.72 mmol) and compound 3 (1 g, 4.08 mmol). The mixture was stirred at room temperature for 16 hours. LCMS showed that the reaction was complete. The reaction solution was purified by preparative HPLC (Welch Xtimate C18 200 × 30 mm × 5 μm water (0.1% FA)-MeCN, 5-95%, 60 mL / min) to give compound 4 (317 mg, 17.84%) as a white solid.

[0240] LCMS: m / z = 613.3 [M-OH] + ,Rt=1.610min.Purity:96.31%(214nm). (3)

[0242]

[0243] A solution of compound 4 (317 mg, 0.5 mmol) in hydrochloric acid (2%, 2 mL) and THF (2 mL) was stirred at room temperature under N2 for 2 hours. LC-MS showed the reaction was complete. The pH was adjusted to 6 with sodium hydroxide (1 M.aq). The reaction solution was purified by preparative HPLC (Welch Ultimate C18 150 × 30 mm × 5 μm, water (0.1% FA)-MeCN, 5-95%, 60 mL / min) to give Bio-Ori-2 (47 mg, 15.83%) as a white solid.

[0247] 3. The procedure for the pull-down assay involves immobilizing a known substance (bait) on a carrier and using it to capture binding proteins (prey) and protein complexes that interact with the binding proteins from a complex mixture. 6 μg / mL of recombinant human NCL (rhNCL) and 6 μg / mL of recombinant human MDM2 (rhMDM2) were mixed and incubated at 4°C for 7 hours. Then, 400 nM of Bio-Ori-1, Bio-Ori-2, biotin-labeled CRO (Bio-CRO: CCTCCTCCTCCTTCTCCTCCTCCTCC, negative control) or iSN04 (Bio-iSN04: AGATTAGGGTGAGGGTGA) was added, and the mixture was incubated at 4°C for 6 hours. Finally, streptavidin agarose gel beads (purchased from Cytiva, catalog number 17511301) were added, and the mixture was incubated overnight at 4°C. The gel beads were washed four times with TBST buffer, then SDS-PAGE protein loading buffer (purchased from Beyotime, catalog number P0015) was added, and the mixture was heated to 100°C for 10 minutes. The supernatant was collected after centrifugation. The product was then analyzed using an immunoblot assay. Figure 2 The results of A and 2B indicate that Ori can bind to NCL but not to MDM2; however, in the presence of NCL, Ori can recruit MDM2 in reliance on NCL. Figure 2 The results of C indicate that CRO cannot bind to NCL or recruit MDM2. Figure 2 The results of D indicate that iSN04 can only bind to NCL, but cannot recruit MDM2 by relying on NCL.

[0248] 4. Hep3B liver cancer cells were lysed with IP lysis buffer (Thermo Scientific, catalog number 87788) and then incubated with different concentrations (0 μM, 200 nM, 500 nM, 1 μM, 5 μM, 10 μM, 20 μM) of Bio-Ori-1, Bio-Ori-2, Bio-CRO or Bio-iSN04 at 4 °C for 6 hours. Then, streptavidin agarose gel beads (Cytiva, catalog number 17511301) were added and incubated overnight at 4 °C. After repeatedly washing the Bio-Ori-1, Bio-Ori-2, Bio-CRO, or Bio-iSN04 bound to the gel beads and the proteins they captured with IP lysis buffer (Thermo Scientific, catalog number 87788), SDS-PAGE protein loading buffer (Beyotime, catalog number P0015) was added, and the mixture was heated to 100°C for 10 minutes. The supernatant, the pull-down product, was collected after centrifugation. The pull-down product was then detected using Western blotting. Figure 3 The results of A and 3B indicate that Ori can capture NCL and MDM2; Figure 3The results of C indicate that CRO cannot capture NCL and MDM2; Figure 3 The results from D indicate that iSN04 can capture NCL, but not MDM2.

[0249] 5. Hep3B liver cancer cells were incubated with DMSO (Vehicle) or 1 μM Bio-Ori-1 for 12 hours. After cell lysis, the supernatant was incubated overnight at 4°C with streptavidin agarose gel beads (purchased from Cytiva, catalog number 17511301). The Bio-Ori-1 bound to the gel beads and the captured proteins were washed multiple times with IP lysis buffer (purchased from Thermo Scientific, catalog number 87788). SDS-PAGE protein loading buffer (purchased from Beyotime, catalog number P0015) was added, and the mixture was heated to 100°C for 10 minutes. After centrifugation, the supernatant, i.e., the pull-down product, was collected. The pull-down product was detected using Western blotting. The results are as follows: Figure 4 As shown in A, Ori can capture NCL and MDM2.

[0250] 6. Hep3B liver cancer cells were transfected with negative control siRNA (siNC: UUCUCCGAACGUGUCACGUTT) or NCL siRNA (siNCL: GGAUGACGACGACGACGAAGATT). After 48 hours, the cells were incubated with 1 μM Bio-Ori-1 for 12 hours to lyse the cells. The supernatant was then incubated overnight at 4°C with streptavidin agarose gel beads. The Bio-Ori-1 bound to the gel beads and the captured proteins were washed multiple times with IP lysis buffer (Thermo Scientific, catalog number 87788). SDS-PAGE protein loading buffer (Beyotime, catalog number P0015) was added, and the mixture was heated to 100°C for 10 minutes. After centrifugation, the supernatant (the pull-down product) was collected and detected using Western blotting. Results are as follows: Figure 4 B, Silent NCL can block Ori from recruiting MDM2.

[0251] 7. Hep3B liver cancer cells were lysed with IP lysis buffer (Thermo Scientific, catalog number 87788) and incubated with different concentrations (0 μM, 1 μM, 5 μM, 10 μM, 20 μM) of Ori or iSN04 at 4°C for 6 hours. Then, NCL antibody was added and incubated overnight at 4°C. Protein A / G magnetic beads (Thermo Scientific, catalog number 88802) were added and incubated at room temperature with rotation for 1.5 hours. The NCL bound to the magnetic beads and the captured proteins were washed with IP lysis buffer (Thermo Scientific, catalog number 87788), and SDS-PAGE protein loading buffer (Beyotime, catalog number P0015) was added. The mixture was heated to 100°C for 10 minutes. The magnetic beads were then adsorbed using a magnetic rack, and the supernatant was transferred to a new tube. An immunoblotting assay was then performed to detect whether Ori or iSN04 affected the interaction between NCL and MDM2. Figure 5 The results of A indicate that Ori does not affect the interaction between NCL and MDM2. Similar results were obtained using other Formula I compounds, with results similar to those for Ori. However, Figure 5 The results of B indicate that iSN04 blocks the binding of NCL to MDM2.

[0252] 8. The above results indicate that compounds of formula I (such as Ori) recruit MDM2 through interaction with NCL, while iSN04, although interacting with NCL, cannot recruit MDM2 through this interaction. Further analysis revealed that compounds of formula I (such as Ori) do not affect the binding of NCL to MDM2, but iSN04 blocks this binding. These data suggest that not all molecules interacting with NCL can be used to recruit MDM2; whether an NCL-interacting molecule can recruit MDM2 depends on whether it affects the formation of the NCL-MDM2 complex. We simulated the three-dimensional structure of the NCL-MDM2 complex using AlphaFold2 and predicted the conformation of the interaction between compounds of formula I (such as Ori) and the NCL-MDM2 complex using HDOCK. The results show that compounds of formula I (such as Ori) do indeed recruit MDM2 through interaction with NCL, and the possible modes of interaction are as follows: Figure 6 As shown.
