AI Technical Summary
Current treatments for Parkinson's disease targeting LRRK2 are not potent, rapid, or selective, and existing LRRK2 kinase inhibitors cause unwanted side effects, while existing LRRK2 degrading compounds are cereblon-based and slow.
Development of heterobifunctional compounds, known as PROTACs, that selectively degrade LRRK2 by recruiting an E3 ubiquitin ligase, inducing ubiquitination and subsequent degradation of LRRK2, with specific compounds like XL01126 and XL01134 showing rapid and potent degradation.
The developed PROTAC compounds achieve rapid and selective degradation of LRRK2, potentially providing effective treatments for Parkinson's disease and related disorders, with XL01126 demonstrating superior potency and selectivity over other compounds.

Abstract
Description
Technical Field
[0001] Disclosed herein is a novel small molecule chimeric proteolysis targeting chimera (PROTAC) that targets and induces rapid and selective degradation of leucine-rich repeat kinase 2 (LRRK2) in the nanomolar concentration range in polyploid cells.
Background Art
[0002] Parkinson's disease (PD) is the second most common neurodegenerative disorder, currently affecting approximately 10 million people worldwide. Due to the rapidly increasing elderly population, this number is predicted to reach 17.5 million by 2040 (Dorsey et al., J Parkinsons Dis. 2018;8(s1):S3-S8.), posing a significant public health problem and economic burden (Feigin et al., Lancet Neurol. 2019 May;18(5):459-480.). So far, all attempts to slow the progression of PD have failed, and effective treatment remains a very important unmet medical need.
[0003] Leucine-rich repeat kinase 2 (LRRK2), encoded by the LRRK2 gene, is a large (286 kDa) multi-domain protein. Armadillo repeat motifs (ARM), ankyrin repeat domains (ANK), leucine-rich repeat domains and WD40 repeat domains are involved in protein-protein interactions; the Ras of complex proteins as a GTPase (ROC) and C-terminal ROC (COR) tandem domain function; the kinase domain (the most studied domain of LRRK2) is involved in autophosphorylation at Ser-1292 (Sheng et al., Sci Transl Med. 2012 Dec 12;4(164):164ra161.) and phosphorylation of the base of Rab GTPases involved in vesicle transport (Steger et al. eLife 2016; 5:e12813). LRRK2 has been found to play a role in both sporadic PD and familial PD (Tolosa et al., Nat. Rev. Neurol. 2020; 16(2):97-107.). Pathogenic mutations in the RocCOR GTPase domain (R1441C / G / H, N1437H, Y1699C) and kinase domain (G2019S, I2020T) result in changes in GTPase and / or kinase activity, and lead to functional changes in vesicle transport, cytoskeletal dynamics, autophagy, lysosomal degradation, neurotransmission, mitochondrial function and many other pathogenic features associated with PD (Tolosa et al., Nat. Rev. Neurol. 2020; 16(2):97-107.).Therefore, targeting the GTPase and kinase activities of LRRK2 is considered a PD treatment method that modifies the underlying pathology by a number of previously described LRRK2 kinase inhibitors, including LRRK2-IN-1 (Deng et al., Nat. Chem. Biol. 2011; 7(4):203-5.), HG-10-102-01 (Choi et al., ACS Med Chem Lett. 2012; 3(8):658-662.), MLi-2 (Fell et al., J. Pharmacol. Exp. Ther. 2015; 355(3):397-409.), PF-06447475 (Henderson et al., J. Med. Chem. 2015; 58(1):419-32.), and the first two LRRK2 kinase inhibitors in clinical trials, DNL201 and DNL151 (Tolosa et al., Nat. Rev. Neurol. 2020; 16(2):97-107.). However, all of these LRRK2 kinase inhibitors are ATP-competitive type 1 kinase inhibitors that preferably promote LRRK2 mislocalization and microtubule binding by binding to the closed conformation of LRRK2 (Deniston et al., Nature 2020; 588(7837):344-349; Watanabe et al. Cell 2020; 182(6):1508-1518.e16.), causing unwanted effects on vesicular transport and on-target side effects observed in the lung and kidney (Andersen et al. Toxicology. 2018; 395:15-22; Baptista et al. Sci. Transl. Med. 2020 Apr 22;12(540):eaav0820.).
[0004] Therefore, alternative LRRK2 targeting strategies, such as, for example, G2019S LRRK2 selective inhibitors (Garofalo et al., J. Med. Chem. 2020; 63(23):14821-14839; Leśniak et al., Eur. J. Med. Chem. 2022; 229:114080.), LRRK2 dimerization inhibitors (Helton et al., ACS Chem. Biol. 2021; 16(11):2326-2338.), GTPase inhibitors, antisense oligonucleotides, type 2 LRRK2 kinase inhibitors (Tasegian et al. Biochem J. 2021; 478(19):3555-3573.), and chimeric LRRK2 target proteolysis compounds (PROTACs) (Konstantinidou et al., ChemMedChem 2021; 16(6):959-965.) (WO2020081682A1, WO2021194878A1, and WO2021194879A1), have been proposed and investigated. However, to date, no potent, rapid, and selective LRRK2 degrading compounds have been reported.
[0005] Induced target proteolysis is a paradigm-shifting drug discovery approach. Heterobifunctional degrading compounds (also known as PROTACs) induce the degradation of target proteins by recruiting an E3 ubiquitin ligase near the target protein, and result in ubiquitination and subsequent degradation of the target protein (Schapira et al. Nat. Rev. Drug Discov. 2019; 18(12):949-963.). Previous efforts towards the development of LRRK2 PROTACs have led to three patents (WO2020081682A1, WO2021194878A1, and WO2021194879A1) and one publication (Konstantinidou et al., ChemMedChem 2021; 16(6):959-965.). However, all of these reported compounds are cereblon-based and show not-so-large LRRK2 degradation and / or are slow degrading compounds.
[0006] In particular, for the treatment of Parkinson's disease and related disorders, there is a need to identify faster, more potent, orally bioavailable, and / or blood-brain barrier penetrating LRRK2 PROTAC degrader compounds that target the GTPase and kinase activities of LRRK2.

Mode for Carrying Out the Invention
[0084] Detailed Description of the Invention The present invention is directed to identifying more rapid, more potent, and potentially orally bioavailable and / or blood-brain barrier permeable LRRK2 PROTAC degrader compounds, qualifying them as chemical probes for studying the biology of LRRK2, further confirming the target validity as a therapeutic concept for PD, and providing potential treatments or preventive methods for PD and related diseases.
[0085] By using HG-10-102-01 as a warhead and engaging multiple different E3 ligase ligands, the inventors developed a first-generation LRRK2 PROTAC. [Chemistry]
[0086] Among the first-generation compounds, SD75, SD82, and SD100 showed moderate LRRK2 degradation (Figures 1 and 2): [Chemistry]
[0087] Next, the second-generation LRRK2 PROTACs were designed and synthesized based on the set of SD75, SD82, and SD100, which are the most potent first-generation LRRK2 PROTACs. Two sets of second-generation LRRK2 PROTACs were designed and synthesized: [Chemistry]
[0088] The Western blot degradation assay of LRRK2 protac was performed using WT and PD-related LRRK2[G2019S] mouse embryonic fibroblasts (MEFs). The second-generation PROTACs were tested in parallel with the first-generation PROTACs SD75, SD82, and SD100. The compounds were tested at concentrations of 33 nM or 1 mM for 4 hours or 24 hours, and two biological replicates per condition were performed to achieve quantification representative of both replicates. Analysis by quantitative immunoblotting was performed using readouts of total LRRK2 (antibody recognizes an epitope at the C-terminus of the protein), Rab10 pThr73 (physiological substrate), and LRRK2 pSer935 (phosphorylation site, a biomarker).
[0089] From the screening of the second-generation LRRK2 PROTACs (Figures 3, 4, 5, and 6), XL01126 and XL01134 were the top two identified compounds: [Chemistry]
[0090] Therefore, in the direct comparison of SD75 vs. XL01126 vs. XL01134 in a dose-dependent assay, SD75 induced partial LRRK2 degradation (Figures 11A - C), XL01134 induced LRRK2 degradation with a “hook effect” (Douglass, et al., J Am Chem Soc. 2013; 135(16): 6092 - 6099.) (Figures 12A - C), and XL01126 induced almost complete LRRK2 degradation (Figures 13A - C).
[0091] Table 1 - Direct degradation comparison of XL01126, XL01134, and SD75, which are LRRK2 - degrading compounds
Table 1
[0092] The results in Table 1 also show that XL01126 and XL01134 are more potent degrading compounds than SD75.
[0093] Table 2 - Direct comparison of pRab10 dephosphorylation by XL01126, XL01134, and SD75
Table 2
[0094] The results in Table 2 show that XL01126 and XL01134 are more potent than SD75 in dephosphorylating pRab10.
[0095] Table 3 - Direct comparison of pSer935 - LRRK2 dephosphorylation by XL01126, XL01134, and SD75
Table 3
[0096] Table 3 shows that XL01126 and XL01134 are more potent than SD75 in the dephosphorylation of pSer935-LRRK2. Parallel comparison of SD75, XL01134, and XL01126 in the time-dependent assay shows that all of SD75 (Figs. 14A - C), XL01134 (Figs. 15A - C), and XL01126 (Figs. 16A - C) can induce the time-dependent degradation of LRRK2, as well as the time-dependent dephosphorylation of pRab10 and LRRK2.
[0097] Table 4 - Summary of dose - response and time - course experiments [Table 4]
[0098] The results show the following: 1) XL01126 is the most potent LRRK2 - degrading compound and induced the fastest LRRK2 degradation among SD75 and XL01134. 2) XL01126 induced the most potent and fastest LRRK2 dephosphorylation and pRab10 dephosphorylation compared to SD75 and XL01134.
[0099] Next, further screening of XL01126 - based compounds was carried out, and Cis - XL01126 was synthesized as a non - degrading control for separating degradation from inhibition. Cis - XL01126 does not bind to the VHL E3 ligase. [Chemical Structure]
[0100] Table 5 - Binding affinities of VH101, Cis - XL01126, and XL01126 tested by fluorescence polarization assay [Table 5]
[0101] XL01126-induced LRRK2 degradation is dependent on the proteasome pathway (Figures 17A-D and 18A-D). XL01126 is LRRK2 R1441C It degraded LRRK2 in a dose-dependent manner in MEF (Figures 19A-C) and macrophage cells (Figures 20A-B), and also degraded LRRK2 in a dose- and time-dependent manner in human PBMC cells (Figures 21A-C, 22A-C, 23A-C). XL01126 induced selective LRRK2 degradation in WT MEFs, as shown by TMT labeling proteomic analysis (Figure 24).
[0102] Table 6 shows that the solubility of XL01126 in PBS and FeSSIP is 0.55 μM and 26.05 μM, respectively. XL01126 can permeate Caco-2 monolayers. XL01126 is stable in mouse plasma and mouse hepatocytes with half-lives of 108.29 and 314.33 minutes, respectively. XL01126 is metabolized in mouse liver microsomes with a half-life of 3.65 minutes.
[0103] Table 6. Physicochemical and in vitro ADME properties of XL01126 [Table 6]
[0104] XL01126 exhibits an attractive in vivo pharmacokinetic profile with an oral bioavailability of 15% and is capable of penetrating the blood-brain barrier (Figures 33, 34, and 35). XL01126 has only a slight binary binding affinity for VHL (Figures 36, 37A, and 37B) and LRRK2 (Figures 38A and 38B), and is inferior to XL01134 and SD75 in binding to VHL and LRRK2 in the permeabilized mode of the VHL and LRRK2 target engagement assays. However, XL01126 has the highest permeability among the PROTACs tested, as demonstrated by the highest IC50 ratio between the permeabilized mode and the live mode engagement assays. XL01126 also forms a higher and more cooperative ternary complex with VHL and LRRK2 compared to XL01134 and SD75 (Figure 39).
[0105] Considering the favorable degradation profiles of XL01126 and XL01134, and the excellent in vivo PK profile of XL01126, further modifications (third generation) of the LRRK2 PROTACs are based on XL01126 and XL01134:

[0107] XL02058, XL02059, XL02060, and XL02063 are based on XL01134 with modifications to the VHL ligand and linker:

[0108] XL02047, XL02048, and XL02049 are based on XL01126 with modifications to the VHL ligand; XL02067B, XL02068, and XL02077 have modifications in the linker:
Chemical Structure
[0109] Most of the compounds from the third generation showed comparable resolution that exceeded XL01126 and XL01134.

[0140] Leucine-rich repeat kinase 2 (LRRK2) is, so far, one of the most promising disease-modifying targets for Parkinson's disease, although current LRRK2 targeting strategies have focused on kinase inhibitors with potential unwanted side effects. Herein, we disclose the discovery of a chimeric protein degradation compound (PROTAC) of LRRK2, exemplified by the compound XL01126, as an alternative LRRK2 targeting strategy. XL01126 induces rapid and potent degradation of LRRK2 protein in multiple cell lines in a dose- and time-dependent manner. Specifically, XL01126 reduces the LRRK2 protein level by 80 - 90% in WT MEF, LRRK2 50 MEF, LRRK2 G2019S MEF, macrophages, and PBMC cells at DC R1441C of 32 nM, 14 nM, 15 nM, 55 nM, and 17 nM, respectively. XL01126 has degradation half-lives of 1.2 hours, 0.6 hours, and 2.4 hours in WT MEF, LRRK2 G2019S MEF, and PBMC, respectively. XL01126 has oral bioavailability (F = 15%) and can penetrate the blood-brain barrier after a single dose of XL01126 by intravenous (5 mg / kg), intraperitoneal (30 mg / kg), or oral administration (30 mg / kg) in mice. All of these properties qualify XL01126 as a chemical probe for studying the biology of LRRK2 in vitro and in vivo, leading to a starting point for future PD drug development and potential therapies.
[0141] Figure 36 shows that VH101, XL01126, SD75, XL01134, and Cis-XL01126 replaced the fluorescent tracer from the VHL protein in a dose-dependent manner, and XL01134 (Ki = 0.16 μM), which showed the most potent replacement and thus the highest binding affinity for VHL, was followed by VH101 (Ki = 0.44 μM) and SD75 (Ki = 0.82 μM). In contrast, XL01126 (Ki > 2.33 μM) showed only slight replacement (binding affinity for VHL), and Cis-XL01126 did not replace the fluorescent tracer.
[0142] Figure 37A shows that in permeabilized HEK293 cells, VH101, XL01126, SD75, and XL01134 can replace the VHL fluorescent tracer from the VHL protein in a dose-dependent manner, and XL01134 (IC 50 = 0.78 μM), which showed the most potent replacement and thus the highest binding affinity for VHL, was followed by VH101 (IC 50 = 1.0 μM) and SD75 (IC 50 = 1.9 μM). In contrast, XL01126 showed only slight replacement (binding affinity for VHL).
[0143] Figure 37B shows that in live HEK293 cells, VH101, XL01126, SD75, and XL01134 can replace the VHL fluorescent tracer from the VHL protein in a dose-dependent manner, and XL01134, which showed the most potent replacement (IC 50 = 0.88 μM) and thus the highest binding affinity for VHL, was followed by VH101 (IC 50 = 1.8 μM) and SD75 (IC 50 = 2.5 μM). In contrast, XL01126 (IC 50=10.1 μM) showed only minor replacement (binding affinity for VHL). XL01126 had the highest IC 50 ratio between the permeabilized mode and live cell mode VHL engagement (IC 50、透過化per / IC 50、生細胞 > 0.99), and thus had the highest permeability among the PROTACs tested, followed by XL01134 (IC 50、透過化per / IC 50、生細胞 = 0.89), and SD75 (IC 50、透過化per / IC 50、生細胞 = 0.76).

[0145] Figure 38B shows that in live HEK293 cells, HG-10-102-01, XL01126, SD75, and XL01134 can replace the LRRK2 fluorescent tracer from the LRRK2 protein in a dose-dependent manner, and HG-10-102-01, which showed the most potent replacement (IC 50 = 0.7 μM) and thus the highest binding affinity for LRRK2, was followed by XL01126 (IC 50 = 1.4 μM), SD75 (IC 50 = 1.8 μM), and XL01134 (IC 50 = 2.2 μM). XL01126 had the highest IC 50has a ratio (1.89) and thus has the highest permeability among the PROTACs tested, followed by XL01134 (IC 50、透過化per / IC 50、生細胞 = 0.91), and SD75 (IC 50、透過化per / IC 50、生細胞 = 0.43).
[0146] Figure 39A shows that XL01126 binds to LRRK2 better in the presence of the VCB protein than in its absence (IC 50 = 0.35 μM vs 2 μM), leading to a positive cooperativity (α) of 5.7. Figure 39B shows that XL01134 binds to LRRK2 better in the presence of the VCB protein than in its absence (IC 50 = 0.79 μM vs 1.1), leading to a positive cooperativity (α) of 1.4. Figure 39C shows that SD75 binds to LRRK2 worse in the presence of the VCB protein than in its absence (IC 50 = 1.4 μM vs 1.1), leading to a negative cooperativity (α) of 0.79.
[0147] Figure 40 shows that XL01126 can induce the highest ternary complex with VHL and LRRK2, followed by SD75 and XL01134. Cis-XL01126 cannot form a ternary complex with VHL and LRRK2.

G2019S It induced a dose-dependent dephosphorylation of Rab10 in MEFs (Figures 44A and 44C).
[0150] Figures 45A, 45B, and 45C show that XL02152 is D max (WT)=68%, DC 50 (WT) = 62 nM, D max (G2019S)=80% and DC 50 (G2019S)=44 nM in WT MEFs and LRRK2, respectively G2019S LRRK2 in MEFs WT and LRRK2 G2019S The results show that XL02152 induced dose-dependent degradation of EC 50 (WT) = 144 nM and EC 50(G2019S) induced dose-dependent dephosphorylation of Rab10 in WT MEF and LRRK2 MEF at 63 nM (Figures 45A and 45C). G2019S EXAMPLE
[0151] Generation of Mouse Embryonic Fibroblasts (MEF) Primary MEF were generated as described in previous studies (Wiggin et al., Mol. Cell Biol. 2002 Apr;22(8):2871-81.). Briefly, uterine horns were harvested from mature female mice at 12.5 E days and transferred to a 10 cm tissue culture dish containing cold PBS. Two forceps were used to tear the yolk sac to isolate each fetus. During each fetus isolation, the forceps were thoroughly washed with 70% ethanol. Fetuses were sorted and tissue pieces were collected into PCR tubes for genotyping. The red tissues of the fetuses (which grow into the heart and liver) were removed. The remaining parts of the fetuses were minced with a surgical scalpel blade and incubated with 7.5 ml of trypsin-EDTA solution in a 37 °C tissue culture CO2 incubator for 10 minutes. The dish was removed from the incubator and single cells were confirmed under an optical microscope. 7.5 ml of complete medium was added to the trypsinized cells, and the cell suspension was transferred to a 15 ml Falcon tube and centrifuged at 1200 rpm for 5 minutes at room temperature. The trypsin was aspirated, the cell pellet was resuspended in 5 ml of fresh complete medium, and the cell suspension was plated in a 60 mm tissue culture dish and incubated at 37 °C in a 5% CO2 tissue culture incubator. MEF at this stage were considered passage 0 and were passaged and expanded for experimental use to confirm genotype by allele sequencing and immunoblotting. MEF were cultured in Dulbecco's Modified Eagle Medium (DMEM) containing 10% (v / v) fetal bovine serum (FBS), 2 mM L-glutamine, 100 U / ml penicillin, and 100 μg / ml streptomycin supplemented with 1× non-essential amino acids and 1 mM sodium pyruvate.
[0152] Generation of bone marrow-derived macrophages (BMDMs) Macrophages were cultured in complete medium containing DMEM, 10% (v / v) heat-inactivated FBS, 20% (v / v) L929 conditioned medium, 2.5% (v / v) HEPES, 2 mM L-glutamine, 100 U / ml penicillin and 100 μg / ml streptomycin, 2% sterile-filtered β-mercaptoethanol, 1× non-essential amino acids, and 1 mM sodium pyruvate. Bone marrow isolation and macrophage differentiation were modified from (Wells et al., 2004), and L929 conditioned medium was utilized as the source of M-CSF for differentiation. Briefly, using scissors and forceps, femurs and tibias were dissected from adult mice, and muscle tissue was carefully removed from the bones. The clean femurs and tibias were placed into a tissue culture dish containing complete medium. The ends of each bone were cut with scissors to expose the bone marrow. The bone marrow was flushed using a 10 ml syringe fitted with a 25-gauge needle containing complete medium. The medium containing the bone marrow was passed through a 70 μm cell strainer, and the progenitor cells were plated onto an uncoated 10 cm bacteriological plate containing 10 ml of complete medium. This was designated as day 0 of isolation. On day 3 after isolation, the macrophages were replenished with 5 ml of fresh complete medium. On day 7 after isolation, the macrophages were rinsed once with PBS and incubated with Versene for 5 minutes in a 37 °C, 5% CO2 tissue culture incubator. The macrophages were detached using a cell scraper and centrifuged at 1200 rpm for 5 minutes at room temperature. The Versene was aspirated, and the remaining cell pellet was resuspended in complete medium. The cell suspension was counted, and the cells were seeded in a 6-well format into tissue culture-treated dishes for experimental analysis at a final cell density of 1 million cells per well.
[0153] PBMC cell isolation and treatment PBMC cells were isolated from human blood according to an existing protocol (dx.doi.org / 10.17504 / protocols.io.bnhxmb7n) and pelleted by centrifugation at 1000 g for 2 minutes. The supernatant was discarded, and for washing, the PBMC pellet was resuspended in PBS containing 2% FBS. The suspension was centrifuged again at 1000 g for 2 minutes, and the PBMC pellet was resuspended in RPMI-1640 (Gibco) medium supplemented with 10% FBS. Next, the cells were seeded in 6-well plates and treated with the test compound at the indicated concentrations and for the indicated periods. After treatment, the cells were harvested into 2 ml Eppendorf tubes, centrifuged at 500 g for 2 minutes to pellet the cells, the supernatant was discarded, and the pellet was resuspended in 1 ml of PBS and centrifuged again at 500 g for 2 minutes. The PBMC pellet was added to a complete EDTA-free protease inhibitor cocktail (Sigma-Aldrich Cat#11836170001) and lysed using 60 μL of lysis buffer containing 50 mM Tris-HCl, pH 7.5, 1% (v / v) Triton X-100, 1 mM EGTA, 1 mM sodium orthovanadate, 50 mM NaF, 0.1% (v / v) 2-mercaptoethanol, 10 mM 2-glycerophosphate, 5 mM sodium pyrophosphate, 0.1 μg / ml microcystin-LR (Enzo Life Sciences), 270 mM sucrose, 0.5 mM DIFP (Sigma, Cat#D0879). DIFP is highly toxic and must be prepared as a 0.5 M stock solution in isopropanol in a fume hood. Next, the lysed cells were centrifuged at 1500 g for 15 minutes at 0 °C. The supernatant was recovered for analysis by quantitative immunoblotting. For long-term storage, the supernatant was snap-frozen and stored at -80 °C. The protein concentration of the cell lysate was measured using the Pierce™ BCA Protein Assay Kit (ThermoFisher).
[0154] Cell Culture, Treatment, and Lysis Subsequent culturing and passage of the cell line were performed using aseptic techniques within a CL1 or CL2 (for PBMC isolation) safety cabinet. All cells were incubated in a 37 °C incubator with 5% CO2. The cell line was periodically tested for mycoplasma contamination. For Western blot assays, cells were seeded in 6-well plates. After treatment with the test compound at the indicated concentrations and time periods, the medium was removed, the cells were washed with PBS, and then lysed in 100 μl of ice-cold complete lysis buffer containing 50 mM Tris HCl, pH 7.4, 1 mM EGTA, 10 mM 2-glycerophosphate, 50 mM sodium fluoride, 5 mM sodium pyrophosphate, 270 mM sucrose, supplemented with 1 μg / ml microcystin-LR, 1 mM sodium orthovanadate, a complete EDTA-free protease inhibitor cocktail (Roche), and 1% (v / v) Triton X-100. The cells were immediately placed on ice, scraped, and collected into a 1.5 ml Eppendorf tube. The cell lysate was incubated on ice for 10 minutes and then centrifuged at 15,000 g for 15 minutes at 4 °C. The cell pellet was discarded and the supernatant was collected for analysis by quantitative immunoblotting. For long-term storage, the supernatant was snap-frozen and stored at -80 °C. The protein concentration of the cell lysate was measured using the Bradford assay.
[0155] Quantitative immunoblotting Cell lysates containing 4×NuPAGE LDS sample buffer (NP0007) supplemented with 5% β-mercaptoethanol in a quarter volume were heated at 95°C for 5 minutes. Samples of 15 - 20 μg were loaded onto precast 4 - 12% Bis-Tris midi 20W or 26W gels (Thermofisher Scientific®, Cat# WG1402BOX or WG1403BOX) and resolved at 130V for 2 hours using NuPAGE MOPS SDS running buffer (Thermofisher Scientific®, Cat#NP0001-02). Proteins were transferred electrophoretically onto a 0.45 μm nitrocellulose membrane (GE Healthcare, Amersham Protran® Supported 0.45mm NC) at 90V for 90 minutes on ice in transfer buffer (48 mM Tris base and 39 mM glycine supplemented with 20% methanol). The transferred membrane was blocked at room temperature for 1 hour with 5% (w / v) non-fat dry milk dissolved in Tris-buffered saline with tween (TBS-T) (50 mM Tris base, 150 mM sodium chloride (NaCl), 0.1% (v / v) Tween-20). The membrane was washed 3 times with TBS-T and incubated overnight at 4°C in the primary antibody. Prior to secondary antibody incubation, the membrane was washed 3 times with TBS-T for 15 minutes each. The membrane was incubated with the secondary antibody for 1 hour at room temperature in the dark. Subsequently, the membrane was washed 3 times with TBS-T with 15-minute incubations for each wash, and protein bands were acquired by near-infrared fluorescence detection using an Odyssey CLx imaging system and quantified using Image Studio software. Graphs were created using Graphpad Prism version 8 software.

[0157] Whole proteome sample preparation and MS analysis Wild-type MEFs were seeded in 10-cm tissue culture dishes at a density of 2 million cells per dish. Cells were treated 4 hours prior to harvest with 0.1% DMSO, 300 nM XL01126, or 300 nM cisXL01126 and harvested into 400 μl of complete lysis buffer supplemented with 1 μg / ml microcystin-LR, 1 mM sodium orthovanadate, a protease inhibitor cocktail without EDTA (Roche), and 1% (v / v) Triton X-100. Cell lysates were incubated on ice for 10 minutes and then subjected to three rounds of high-energy sonication for 15 cycles (30 seconds on, 30 seconds off) using a Diagenode Bioruptor. Cell lysates were centrifuged at 15,000 g for 15 minutes at 4 °C. The cell pellet was discarded and the supernatant was recovered for protein quantification using a BCA protein assay kit (Pierce #23225). 100 μg of cell lysate was utilized for global proteome analysis. Proteins in the cell lysate were reduced with 0.1 M Tris(2-carboxyethyl)phosphine (TCEP) (TEABC) diluted with 300 mM triethylammonium bicarbonate to a final concentration of 10 mM. Samples were incubated at 60 °C, 800 rpm for 30 minutes in a thermomixer. Samples were incubated to room temperature and subjected to alkylation with 0.4 M iodoacetamide (IAA) freshly dissolved in water. Samples were then incubated in the dark at room temperature, 800 rpm for 30 minutes in a thermomixer. Alkylation was quenched by the addition of 0.1 M TCEP dissolved in 300 mM TEABC to a final concentration of 5 mM. Samples were incubated at room temperature, 800 rpm for 20 minutes in a thermomixer. Sodium dodecyl sulfate (SDS) was added from a 20% (w / v) stock to a final concentration of 5% (w / v). Next, 12% (v / v) phosphoric acid was added to a final concentration of 1.2% (v / v). Samples were diluted 6-fold with S-trap wash buffer containing 90% (v / v) methanol diluted with 100 mM (v / v) TEAB pH 7.1 to the sample volume.
[0158] S-trap Purification and Digestion The sample was subjected to S-trap purification and the washing agent and other impurities were removed using an S-trap mini column (PROTIFI Cat# MSPPC02-MINI-80) placed in a 2 ml Eppendorf. The protein mixture was added to the column and centrifuged gently (1000 g / 1 minute / RT). The column was washed 4 times with 400 μl of S-trap buffer and centrifuged after each wash (1000 g / 1 minute / RT). The column was placed in a new 2 ml Eppendorf and 100 μl of 5 μg of trypsin / Lys-C newly dissolved in 50 mM TEAB, pH 8.5 was added. The column was centrifuged gently (200 g / 1 minute / RT), and the trypsin / Lys-C mixture was pipetted back onto the column. 100 μl of 50 mM TEAB, pH 8.5 was added directly to the 2 ml Eppendorf to cover all the digested peptides remaining in the tube. The S-trap column in the 2 ml Eppendorf was incubated at 47 °C for 1.5 hours without shaking and then incubated overnight at RT.
[0159] 80 μl of 50 mM TEAB was added to the S-trap column, and it was centrifuged, and the eluate was collected in a new 1.5 ml Eppendorf tube. 80 μl of 0.2% (v / v) formic acid was added to the column, and it was centrifuged, and the second eluate was stored together with the first eluate. 80 μl of 50% (v / v) acetonitrile diluted with 0.2% (v / v) formic acid was added to the column, and it was centrifuged, and the third eluate was stored together with the previous eluates. 500 ng of the digested peptides were taken for vacuum drying respectively to confirm that the digestion efficiency was >90%. The remaining peptides were divided in half (50 μg of peptides in each tube), vacuum dried, and stored at -80 °C before the continuation of tandem mass tag (TMT) labeling.
[0160] TMT Labeling 800 μg of the TMT mass tag reagent was dissolved in 80 μl of 100% (v / v) anhydrous acetonitrile to obtain a final concentration of 10 μg / μl. The resuspended TMT reagent was incubated at RT for 10 minutes, then vortexed and gently centrifuged (2000 g / 2 minutes / RT). 50 μg of lyophilized peptide was resuspended in a 50 μl mixture containing 38 μl of 50 mM TEAB and 8 μl of 100% (v / v) anhydrous acetonitrile. The resuspended peptide was sonicated for 10 minutes and then centrifuged at 17,000 g, RT for 10 minutes. The peptide was transferred to a new protein low-binding 1.5 ml Eppendorf tube. 20 μl of 10 μg / μl TMT reagent was added to the solubilized peptide, vortexed, gently centrifuged (2,000 g / 1 minute / RT), and incubated in a thermomixer at 800 rpm, RT for 2 hours. 50 μl of 50 mM TEAB was added to each reaction, followed by vortexing, gentle centrifugation (2,000 g / 1 minute / RT), and incubation in a thermomixer at 800 rpm, RT for an additional 10 minutes. 5 μl of each TMT-labeled sample was taken, vacuum dried, and injected into the MS to confirm that the labeling efficiency was >98%. The remaining reactions were stored at -80 °C until the labeling efficiency was confirmed. The TMT samples were thawed to RT, and the labeled reactions were quenched using the addition of 5 μl of 5% (v / v) hydroxylamine (dissolved in water from a 50% (v / v) stock solution). The samples were incubated in a thermomixer at 800 rpm, RT for 20 minutes. The quenched TMT-labeled samples were pooled and processed using C18 stage-tip desalting.
[0161] Pharmacokinetic (PK) investigation PK profiling was outsourced and commissioned by Shanghai ChemPartner Co., Ltd. All animal experiments conducted were performed in accordance with the Institutional Animal Care and Use Committee (IACUC) and Office of Laboratory Animal Welfare (OLAW) guidelines. Six- to eight-week-old male C57BL / 6 mice purchased from Jihui Laboratory Animal Co., LTD were used in the study. XL01126 was formulated in 10% HP-β-CD in 50 mM citrate buffer pH = 3.0 at 1 mg / mL for intravenous injection and 3 mg / mL for IP and PO injection. For intravenous injection, 5 mg / kg of XL01126 was administered via the tail vein to 9 mice. For IP injection, 30 mg / kg of XL01126 was administered by intraperitoneal injection in mice. Animals were manually restrained at the indicated time points (0.083, 0.25, 0.5, 1, 2, 4, and 8 hours); approximately 110 μL of blood samples were collected into K2EDTA tubes via the facial vein. Three mice were used per time point, and as a result, a total of 21 mice were used per administration route. Blood samples were placed on ice and centrifuged at 2000 g for 5 minutes to obtain plasma samples within 15 minutes. Plasma, brain, and CSF samples were stored at approximately -70 °C until analysis. To 30 μL aliquots of plasma, 200 μL of internal standard (Glipozode, 40 ng / mL) in MeCN containing 5% citric acid was added. The mixture was then vortexed for 1 minute and then centrifuged at 5800 rpm for 10 minutes. The supernatant (100 μL) was transferred to a new plate. Solvent (1 μL) was injected into the LC-MS / MS. LC-MS / MS instrument used: SCIEX LC-MS / MS-49 (Triple Quad 6500+). Data were analyzed by WinNonLin and Microsoft Excel.
[0162] Fluorescence polarization assay The FP competition binding assay was carried out according to the previously described method (Bond et al, J. Med. Chem. 2021, 64 (20), 15477-15502.). All measurements were obtained using a PHERstar (BMG LABTECH) plate reader incorporating an FP filter with excitation and emission wavelengths set at 485 nm and 520 nm (nM), respectively. Each well of a 384-well plate (Coring 3575) contained 10 nM of VCB protein, 5 nM of FAM-labeled HIF-1α peptide (FAM-DEALAHypYIPMDDDFQLRSF, "JC9"), and the concentration of PROTAC was lowered (14 concentrations by 2-fold serial dilution starting from 250 μM) with FP assay buffer (100 mM Bis-Tris propane, 100 mM NaCl, 1 mM TCEP, pH 7) having a final DMSO concentration of 5%. Control wells containing VCB and JC9 without compound were set to the maximum signal (replaced with zero). Additionally, JC9-containing control wells without protein were set to the minimum signal. The control values were used to obtain the percentage of replacement graphed against Log[compound]. For each titer measurement, mean IC 50 values were measured using non-linear regression analysis with Prism (v.9.3.1). K i values were calculated inversely from the K d (1.5 nM - 3.4 nM) of JC9 and the fitted IC 50 values as previously described.

To measure NanoBRET in permeabilized cells, the cells were treated with 50 μg / mL digitonin (Sigma, D141), 125 nM VHL tracer / 125 nM LRRK2 tracer, serially diluted concentrations of the test compound (12 concentrations by 2-fold serial dilution starting from 33 μM), and NanoBRET NanoGlo Substrate (Promega) at a concentration recommended by the manufacturer's protocol. In the maximum signal control sample (DMSO control), DMSO was added instead of the test compound. In the minimum signal control sample (no-tracer control), DMSO and tracer dilution buffer were used to replace the test compound and tracer, respectively. The filtered luminescence was measured within 10 minutes after substrate addition using a GloMax Discover microplate reader (Promega) equipped with a 450 nm bandpass filter (donor) and a 600 nm longpass filter (acceptor) or a PHERAstar (BMG LABTECH) plate reader. To measure NanoBRET in live cells, the cells were treated with 250 nM VHL tracer / 500 nM LRRK2 tracer, serially diluted concentrations of the test compound (12 concentrations by 2-fold serial dilution starting from 33 μM), and incubated for 2 hours at 37 °C in an incubator. The plates were then cooled and NanoBRET NanoGlo Substrate and Extracellular NanoLuc Inhibitor (Promega, N2160) were added before NanoBRET readings in the same mode as for permeabilized cells using a plate reader.The NanoBRET ratio for each well was expressed in milliBRET according to the following equation: mBRET = [(signal at 610 nM / signal at 450 nM) - (signal at 610 nM of the no-tracer control / signal at 450 nM of the no-tracer control)] × 1000. The fractional occupancy was calculated according to the following equation: fractional occupancy = (mBRET of the tested compound - mBRET of the no-tracer control) / (mBRET of the DMSO control - mBRET of the no-tracer control).
[0164] NanoBRET-based ternary complex and cooperativity assay HEK293 cells were transfected with the LRRK2-NanoLuc fusion vector (Promega, NV3401) according to the Promega protocol and seeded into white 384-well plates (Corning 3570) at a density of 6000 cells / well.

The first six concentrations of VCB were by 2-fold dilution starting from 32 μM, and the last five concentrations of VCB were maintained at 1 μM), and NanoBRET NanoGlo Substrate (Promega) at the concentration recommended by the manufacturer's protocol. For the maximum signal control sample (DMSO control), DMSO was added in place of the test compound. For the minimum signal control sample (no-tracer control), DMSO and LRRK2 tracer dilution buffer were used to replace the test compound and LRRK2 tracer, respectively. The filtered luminescence was measured within 10 minutes after substrate addition using a PHERAstar (BMG LABTECH) plate reader equipped with a 450 nm bandpass filter (donor) and a 600 nm longpass filter (acceptor). The fractional occupancy was calculated according to the following equation: fractional occupancy = (mBRET of the tested compound - mBRET of the no-tracer control) / (mBRET of the DMSO control - mBRET of the no-tracer control).
