Description

[Background technology]

[0001] Introduction Glioblastoma (GBM) is the most common primary malignant brain tumor in the United States (Ostrom et al., 2019). The prognosis for GBM is poor, with a median survival of 12 months, which extends to 14 months with current standard-of-care treatment (Stupp et al., 2005). Standard treatment, consisting of surgical resection followed by radiation therapy and temozolomide, has demonstrated protective antitumor activity but is associated with relapse and tumor recurrence. One of the key factors contributing to the poor outcomes of GBM patients is the scarcity of effective treatments for GBM. Summary of the Invention [Means for solving the problem]

[0002] The present invention provides small molecule inhibitors of lanosterol synthase, a cholesterol biosynthetic enzyme. Inhibiting lanosterol synthase with the small molecule inhibitors of the present invention inhibits lanosterol biosynthesis, thereby inhibiting cholesterol biosynthesis. The small molecule inhibitors of the present invention divert biosynthesis toward the synthesis of the non-canonical sterol 24,25-epoxycholesterol (EPC). Upregulating EPC with small molecule inhibitors of lanosterol synthase can specifically and potently kill glioblastoma cell lines. The present invention also provides representative analogs of lanosterol synthase inhibitors that are capable of killing glioblastoma cell lines at low concentrations in the single-digit nanomolar range. In some embodiments, the inhibitors of the present invention are orally ingestible and / or brain-permeable. Furthermore, the present invention provides methods and compositions for treating glioblastoma, as well as methods and compositions for developing novel therapies for treating glioblastoma.

[0013] In the following detailed description, and throughout this specification, unless inappropriate or stated otherwise, "a" and "an" mean one or more, and "or" means "and / or." The examples and embodiments described herein are for illustrative purposes only. Various modifications and variations of these examples and embodiments will be suggested to one of ordinary skill in the art, and these modifications and variations are within the spirit and scope of this application and the appended claims. All publications, patents, and patent applications cited herein, including the references cited therein, are hereby incorporated by reference in their entirety for all purposes.

[0014] Herein, we demonstrate that the tetracyclic dicarboximide MM0299 inhibits lanosterol synthase (mouse lanosterol synthase is referred to as "Lss" and human lanosterol synthase is referred to as "LSS"). Lanosterol synthase is the first enzyme in the cholesterol biosynthetic pathway after squalene synthesis to synthesize the tetracyclic sterol skeleton. Like other LSS inhibitors, MM0299 blocks canonical cholesterol biosynthesis and diverts sterol synthesis toward the production of the shunt pathway product, 24(S),25-epoxycholesterol (EPC). EPC inhibits the proliferation of glioblastoma stem-like cells (GSCs) by depleting intracellular cholesterol. Compared to known LSS inhibitors, MM0299 exhibits superior selectivity for LSS over other sterol biosynthetic enzymes. The present inventors have demonstrated that MM0299 derivatives are orally bioavailable, penetrate the blood-brain barrier, and stimulate EPC production in tumors but not in normal brains. The present invention provides novel lanosterol synthase inhibitors as a treatment for glioblastoma or other neurological disorders.

[0015] A selective and brain-penetrant lanosterol synthase inhibitor targets glioma stem-like cells by activating the shunt pathway that generates the toxic metabolite 24(S),25-epoxycholesterol To generate pharmacologically optimized preclinical lead LSSi, medicinal chemistry development activities were conducted and followed up to evaluate target binding, safety, and anti-GBM activity profiles. Structure-activity relationships (SAR) were analyzed for a large number of analogs generated by medicinal chemistry techniques, and EC values ​​were measured in cellular probe-based displacement assays. 50 We distinguished between on-target and off-target binding events by correlating SAR data with cell phenotype. Furthermore, to identify chemicals that compromise GBM cell health, we generated a GBM transgenic mouse model by inducing spontaneous tumor formation in mouse astrocytes through GFAP-Cre-mediated silencing of the tumor suppressors Trp53, Pten, and Nf1. We then performed a high-throughput cell survival screen using the mouse GBM stem cell-like cell (GSC) line Mut6 derived from this GBM transgenic mouse model.

[0016] We investigated the mechanism of action of a tetracyclic dicarboximide (MM0299) identified through screening. MM0299 inhibits lanosterol synthase (mouse lanosterol synthase is referred to as "Lss" and human lanosterol synthase is referred to as "LSS"). Lanosterol synthase is the first enzyme in the cholesterol biosynthetic pathway after squalene synthesis, synthesizing the tetracyclic sterol skeleton. Inhibition of LSS by MM0299 blocks canonical cholesterol biosynthesis and diverts sterol synthesis to the shunt pathway product 24(S),25-epoxycholesterol (EPC), resulting in the inhibition of glioblastoma stem-like cell (GSC) proliferation.

[0017] The present invention provides a novel approach to targeting tumor cellular metabolism for the treatment of brain tumors. Metabolic reprogramming is a fundamental feature of the molecular pathogenesis of gliomas, and numerous therapeutic strategies designed to exploit this process are currently undergoing preclinical and clinical trials (Zhou and Wahl, 2019). One such strategy targets metabolic pathways that exhibit greater flux in glioma cells compared to normal cells. For example, a study evaluating the radiosensitizing effects of inhibiting purine nucleotide synthesis in GBM has been reported (NCT04477200) (Zhou et al., 2020). Another strategy has been reported to block the synthesis of the oncometabolite 2-hydroxyglutarate, which selectively accumulates in gliomas, leading to the formation of gliomas with mutant isocitrate dehydrogenase (IDH) (NCT02481154) (Mellinghoff et al., 2021). Unlike these strategies, our approach demonstrates a new paradigm that activates, rather than inhibits, metabolic pathways in GBM cells to induce the production of tumor-specific cytotoxic metabolites, EPCs.

[0018] Regarding clinical translation, we report a derivative of MM0299 that is orally bioavailable and capable of penetrating the blood-brain barrier. These findings support the development of lanosterol synthase inhibitors as treatments for glioblastoma or other neurological disorders.

[0019] result 1. MM0299 inhibits the proliferation of Mut6 cells by binding to lanosterol synthase Spontaneous tumor formation in mouse astrocytes can be induced by silencing the tumor suppressors Trp53, Pten, and Nf1 via GFAP-Cre, and these tumors are histologically similar to human GBM (Kwon et al., 2008). Next, a glioma stem cell-like cell (GSC) line (hereafter referred to as "Mut6") derived from GBM tumors formed in this model was used in a high-throughput chemical screen to identify small molecules that inhibit GSC proliferation (Shi et al., 2019). MM0299 (1), a tetracyclic dicarboximide obtained from this screen, dose-dependently reduces the viability of Mut6 cells (IC). 50 =0.0182μM). [ka]

[0020] We attempted to elucidate the mechanism of action (MoA) of MM0299 by identifying the protein to which MM0299 binds in Mut6 cells. To achieve this goal, we synthesized the MM0299-probe (2). This MM0299-probe is an analog of MM0299 (IC) that maintains antiproliferative activity in Mut6 cells. 50= 1.18 μM) and contains both diazirine and alkyne functional groups. Exposure of the photoreactive diazirine group to ultraviolet (UV) light forms a reactive carbene, which can react with neighboring amino acid residues and thereby covalently bind to proteins. Mut6 cells were incubated with increasing concentrations of Probe 2 in the presence or absence of UV treatment (306 nm), and the resulting lysates were reacted with fluorescent azides in a copper(I)-catalyzed azide-alkyne cycloaddition reaction (commonly referred to as "click" chemistry). Analysis of the clicked lysates by SDS-PAGE revealed multiple fluorescent protein bands representing various proteins covalently bound to Probe 2. Several of these protein bands showed a dose-dependent increase in fluorescence intensity only under UV conditions, with the most prominent being a protein (p75) migrating at approximately 75 kDa.

[0021] To investigate whether binding to the observed bands was related to toxicity, we performed a series of probe-based displacement assays by co-incubating cells with a fixed concentration of probe 2 and an increasing concentration series of competitor compound 1. We hypothesized that compound 1 would reduce the intensity of the fluorescent band of the putative target in a dose-dependent manner. Although probe 2 bound to multiple proteins, we observed a dose-dependent reduction in the fluorescence of only p75. We performed repeated probe displacement assays with 12 structurally related MM0299 derivatives (analogs 3–14 in Table 1; see Supplementary Information for their syntheses and structures) and determined the EC values ​​for binding to p75. 50 Structure-binding relationships were investigated by quantifying the IC value, i.e., the concentration of competitor compound required to displace 50% of the signal bound to the probe. In parallel, the dose-dependent antiproliferative activity of each derivative was measured to determine its IC 50 The structure-activity relationship was obtained by determining the EC values ​​of the displacements of the p75 probe. 50 values ​​and IC of antiproliferative activity 50The relationship between the values ​​was plotted, and the slope of the best-fit line was 1.06, indicating EC 50 The IC values ​​indicate antiproliferative activity. 50 Furthermore, there was a significant correlation (R ) between p75 binding and cytotoxic activity over a 1000-fold effective range. 2 =0.864, p<0.0001), providing evidence that p75 is the functional target of MM0299.

[0022] To determine the identity of p75, we performed large-scale affinity purification of proteins that showed binding to the probe. We performed a 1.0 μM IC400 assay using 0.1 μM probe 2 and 1.0 μM IC400 of analog 11, an active competitor. 50 Mut6 cells were incubated with MM0299 (0.000791 μM) or DMSO, followed by UV crosslinking. The probe-binding proteins were biotinylated by a click reaction using biotin azide in cell lysates, and affinity purified using immobilized streptavidin. Proteins eluted from streptavidin beads were digested with trypsin, and the resulting peptides were identified by liquid chromatography-mass spectrometry (LC-MS). Analysis of the LC-MS data from the above purification revealed that lanosterol synthase (Lss) was the most enriched protein when purified using only the probe, demonstrating a 15.5-fold enrichment compared to purification using the probe and a competitor compound. These data indicated that p75 was Lss (MW = 83.1 kDa). Surprisingly, no other proteins were enriched more than two-fold, suggesting few other targets of MM0299.

[0023] Next, we combined pharmacology and genetics to further test whether p75 is indeed an LSS. First, we investigated whether Ro 48-8071, a structurally distinct LSS inhibitor from MM0299, could displace the MM0299-probe (2) using a method similar to the MM0299-series probe displacement assay described above. The intensity of the p75 band decreased with increasing concentrations of Ro 48-8071, indicating that Ro 48-8071 displaced the MM0299-probe in a dose-dependent manner. Furthermore, Ro 48-8071 was able to displace the MM0299-probe at concentrations (EC ) that were higher than the observed concentration (EC ) of MM0299 binding to p75. 50 = 0.00248 μM) 50 = 0.0112 μM) inhibited the proliferation of Mut6 cells. To further investigate whether p75 is an Lss, we assessed probe binding in HEK293T cells ectopically expressing FLAG epitope-tagged human LSS. Incubation of these HEK293T cells with probe 2 and crosslinking enhanced the p75 band intensity, whereas addition of excess competitor compound 1 reduced the p75 band intensity, demonstrating specificity. These results provide evidence that p75, the direct target of MM0299, is an Lss.

[0024] 2. MM0299(1) inhibits the activity of Lss, thereby suppressing the canonical pathway and inducing the shunt pathway. LSS inhibitors block the canonical cholesterol biosynthetic pathway (known as the Bloch and Kandutsch-Russell pathways) and simultaneously stimulate the production of 24(S),25-epoxycholesterol (EPC) via the "shunt" pathway (Mark et al., 1996; Morand et al., 1997). In sterol synthesis, squalene, a symmetric polyene hydrocarbon intermediate in the cholesterol biosynthetic pathway, is oxidized by squalene epoxidase (SQLE) in the presence of NADPH and oxygen to produce (S)-2,3-oxidosqualene (OS), which is then converted to lanosterol by LSS. Inhibition of LSS allows (S)-2,3-oxidosqualene (OS) to be returned to squalene epoxidase (SQLE), which then catalyzes a second oxidation event to produce (S,S)-2,3:22,23-dioxidosqualene (DOS) with C2 symmetry. DOS is a highly reactive substrate for LSS, and even in the presence of LSS inhibitors, DOS is converted by LSS to produce 24(S),25-epoxylanosterol (EPL) (Boutaud et al., 1992). EPL is further converted to EPC by the same enzymes that convert lanosterol to cholesterol (Nelson et al., 1981a; Nelson et al., 1981b). The overall result of LSS inhibition is a decrease in the concentrations of various intermediates in the canonical pathway and an increase in the concentrations of various intermediates in the shunt pathway. Based on this, to test the hypothesis that compound 1 is an LSS inhibitor, we quantified key intermediates in the canonical and shunt pathways after treatment with various doses of compound 1. Treatment of Mut6 cells with compound 1 dose-dependently increased (up to 6.48-fold) the primary substrate of LSS, (S)-2,3-oxidosqualene, and dose-dependently decreased (up to 24.5-fold) the product, lanosterol (IC). 50= 0.0455 μM). Treatment with compound 1 also dose-dependently increased the shunt pathway intermediates DOS and EPL (up to 17.9- and 25.6-fold, respectively). The concentration of EPC, the end product of the shunt pathway, peaked at 390 ng / mg protein (a 13.9-fold increase) when cells were treated with 0.1 μM compound 1, but gradually decreased with higher concentrations of compound 1. The decrease in EPC with high concentrations of compound 1 was likely due to complete inhibition of LSS. Meanwhile, DOS and EPL concentrations continued to increase even above the dose at which EPC decreased. These data suggest that the decrease in EPC concentration at high doses is likely due to catabolism or excretion, rather than decreased synthesis. Related to this hypothesis, in astrocytes, EPC stimulates the expression of sterol transporters, such as ABCA1, which facilitates the extracellular export of EPC itself (Wong et al., 2007). We hypothesized that a threshold concentration of EPCs obtained by treatment with high concentrations of compound 1 activates sterol transporter expression, leading to the excretion of EPCs and the observed decrease in EPC concentration. Based on these results, we concluded that inhibition of Lss by MM0299 (1) dose-dependently decreases canonical intermediates and increases shunt pathway intermediates.

[0025] Next, we evaluated whether MM0299 (1) and related analogs could directly inhibit recombinant human LSS in cell-free in vitro reactions. Recombinant LSS purified from E. coli converted (S)-2,3-oxidosqualene to lanosterol in a time- and dose-dependent manner. Notably, lanosterol production reached saturation over time, which was attributed to substrate depletion or product inhibition. Enzyme activity was assessed over a 30-minute period using 64 μM substrate, a condition under which the reaction remained linear despite this saturation. Under these conditions, compound 1 dose-dependently inhibited the in vitro activity of LSS, with an IC 50The solubility of LSS was 2.22 μM. Similar experiments with three analogs (3, 6, and 14) supported the notion that inhibition of LSS enzyme activity correlated with anti-GBM activity in Mut6 cells. Notably, the concentrations of compound required to inhibit LSS activity in vitro were found to be significantly higher than those required to inhibit cell proliferation. This discrepancy may be explained by the in vitro reaction conditions, in which a nonionic detergent was added to the aqueous buffer, affecting the solubility or binding of the substrate or compound.

[0026] Regarding the shunt pathway, the question remained as to how LSS was able to convert DOS to EPL, even in the presence of high concentrations of inhibitors. Analysis of the enzyme kinetics in vitro showed that the conversion rate of DOS to EPL was faster than that of OS to lanosterol, suggesting that DOS is a highly reactive substrate for LSS (Boutaud et al., 1992). To address this question, the efficacy of LSS in converting DOS to EPL was evaluated in vitro. Consistent with previously reported results, the conversion rate of DOS to EPL was 2.67-fold faster than that of OS to lanosterol. Despite these results, the efficacy of MM0299(1) in inhibiting the conversion of DOS to EPL and the conversion of OS to lanosterol were comparable (IC ). 50 =1.60 and IC 50 = 2.22 μM). Therefore, the conversion of DOS to EPL by LSS in the presence of MM0299 could not be explained solely by the high affinity of LSS for DOS. A more plausible explanation could be derived from the observation that the concentration of DOS was 375-fold higher than that of OS in cells treated with compound 1. The effective concentration of DOS in the endoplasmic reticulum membrane may be even higher, potentially limiting the access of the inhibitor to the enzyme active site.

[0027] 3. Induction of the shunt pathway by MM0299 contributes to its toxicity to Mut6 cells We next investigated whether the increased EPC concentration resulting from LSS inhibition by MM0299 contributes to the antiproliferative activity observed in Mut6 cells. EPC is a potent ligand for the nuclear hormone transcription factor LXR, which promotes cholesterol efflux by upregulating cholesterol transporters such as ABCA1 and ABCG1 (Janowski et al., 1999; Janowski et al., 1996; Lehmann et al., 1997; Willy et al., 1995). Furthermore, EPC inhibits the activation of SREBP, a master transcription factor that promotes the expression of multiple enzymes involved in cholesterol biosynthesis and uptake (Horton et al., 2003; Radhakrishnan et al., 2007). mRNA sequencing showed that treatment of Mut6 cells with compound 1 upregulated LXR target genes, such as Abca1, Abcg1, and Srebf1, while simultaneously downregulated SREBP target genes, indicating that the concentration of EPCs generated by compound 1 treatment was sufficient to affect these pathways ( Horton et al., 2003 ; Willy et al., 1995 ).

[0028] To further evaluate the role of EPC in the anticancer activity of compound 1, we investigated whether the EPC concentration achieved by treating cells with compound 1 was sufficient to exert toxicity. Incubation of cells with a polydeuterated derivative of 24(S),25-epoxylanosterol (d6-S-EPL) resulted in the time-dependent generation of d6-EPC, which inhibited the proliferation of Mut6 cells, with IC 50 The concentration of d6-EPC produced by incubating cells with an effective dose of d6-S-EPL (1 μM) was 0.483 μM. Notably, the concentration of d6-EPC produced by incubating cells with an effective dose of d6-S-EPL (1 μM) was comparable to the EPC concentration detected after treatment with a lethal dose of compound 1 (0.1 μM) (390 ng of d6-EPC per mg of protein and 342 ng of EPC per mg of protein). These data indicate that the EPC synthesized after treatment with compound 1 is sufficient to inhibit cell proliferation.

[0029] Based on these results, we concluded that the concentration of EPCs generated by treatment with compound 1 was sufficient to downregulate SREBP target genes, upregulate LXR target genes, and inhibit cell proliferation. EPCs could reduce intracellular cholesterol concentrations to lethal levels by exerting a coordinated action on LXR and SREBP, transcriptional regulators crucial for cholesterol homeostasis. To test this hypothesis, we assessed the proliferation of cells treated with increasing concentrations of S-EPL or compound 1 in the presence of exogenous lanosterol or cholesterol bound to methyl-β-cyclodextrin (MCD), which aids in the solubility and delivery of sterols. Addition of lanosterol or cholesterol to the cells rescued Mut6 cells from S-EPL or compound 1-induced toxicity. These observations provided evidence that the antiproliferative activity of compound 1 is due to the generation of EPCs and the resulting depletion of intracellular cholesterol.

[0030] Next, we considered pharmacological tools that could selectively block the shunt pathway to assess whether EPC is required for MM0299 activity. Regarding LSS inhibition, the generation of DOS requires two cycles of oxidation by squalene epoxidase (SQLE), whereas the generation of OS requires only one cycle of oxidation. Based on this, we speculated that coadministration of an SQLE inhibitor would have a more potent effect on DOS concentrations and disrupt flow through the shunt pathway. Consistent with this expectation, simultaneous treatment with a sublethal dose of the SQLE inhibitor NB-598 completely inhibited the accumulation of shunt pathway metabolites by compound 1, but did not reduce canonical sterol concentrations (Horie et al., 1990). From these results, we concluded that NB-598 selectively blocks the shunt pathway and therefore can be used as a pharmacological tool to assess whether EPC is required for MM0299 activity. Furthermore, NB-598 dose-dependently rescued the toxicity of compound 1, thereby reducing IC 50 We found an 11.8-fold increase in LSS levels. In contrast, NB-598 did not rescue the activity of bortezomib, a compound with a mechanism unrelated to cholesterol synthesis, nor did it rescue the activity of TASIN-30, an inhibitor of emopamil-binding protein (EBP), an enzyme downstream of LSS in cholesterol biosynthesis (Theodoropoulos et al., 2020). These observations are consistent with the hypothesis that LSS inhibition and the resulting increase in EPCs are responsible for its toxicity in the low nanomolar range. Furthermore, compound 1 remained toxic to Mut6 cells at high concentrations, even in the presence of NB-598. This toxicity at such high concentrations, which appears pharmacologically unattainable, is likely due to sterol depletion caused by direct inhibition of cholesterol biosynthesis rather than the generation of EPCs. Taken together, these observations led us to conclude that the specific induction of the shunt metabolite EPC is necessary and sufficient to achieve the most potent cytotoxic effect of MM0299 in Mut6 cells.

[0031] 4. Evaluation of LSS selectivity of MM0299 and known LSS inhibitors Enzyme selectivity is a major challenge in developing inhibitors of the cholesterol biosynthetic pathway following squalene synthesis (Korade et al., 2016; Moebius et al., 1998; Wages et al., 2018). This polypharmacology can be particularly problematic when using LSS inhibitors as anti-GBM agents, as inhibition of downstream biosynthetic enzymes also inhibits the production of the key metabolite, EPC (Rabelo et al., 2017). With this in mind, we systematically compared the off-target profile of compound 1 with that of another LSS inhibitor, Ro 48-8071, which has undergone extensive pharmacological and biophysical evaluation, including structural determination of its complex with LSS (Morand et al., 1997; Thoma et al., 2004).

[0032] Treatment with Ro 48-8071, like compound 1, increased shunt pathway intermediates in a dose-dependent manner, and the peak concentration of EPCs generated by treatment with Ro 48-8071 correlated with its toxicity to Mut6 cells (IC 50= 0.0112 μM). Notably, the peak EPC concentration after treatment with Ro 48-8071 was only 62% of that after treatment with compound 1. Based on the peak EPC concentration after treatment with Ro 48-8071, we hypothesized that Ro 48-8071 attenuates EPC synthesis by inhibiting one or more enzymes downstream of LSS. To assess whether Ro 48-8071 inhibits EPC synthesis downstream of EPL, we cultured cells with isotope-labeled EPL (d6-EPL) and treated them with each inhibitor, and then measured the production of d6-EPC. Ro 48-8071 inhibited d6-EPC production, whereas compound 1 had no effect on d6-EPC production. These data suggest that Ro 48-8071 inhibits LSS but also exerts off-target effects on the sterol synthesis pathway downstream of LSS, thereby attenuating EPC synthesis. In the case of small molecule inhibitors that inhibit enzymes downstream of LSS, lanosterol is not expected to rescue toxicity as effectively as cholesterol, because lanosterol is not efficiently converted to cholesterol. Consistent with this hypothesis, the rescue effect of exogenous cholesterol (IC) on Ro 48-8071 was significantly lower than that of cholesterol. 50 The 479.4-fold increase in IL-14 (IC ) was consistent with the rescue effect of exogenous lanosterol (IC 50 The effect of compound 1 on the cytotoxicity of LSS was more potent than that of exogenous lanosterol (a 21.7-fold increase in LSS). In contrast, exogenous lanosterol and exogenous cholesterol showed similar and complete rescue effects in cells treated with compound 1. These findings indicate that compound 1 does not inhibit enzymes downstream of LSS in the cholesterol synthesis pathway, resulting in more efficient production of the toxic metabolite EPC.

[0033] To eliminate bias in identifying potential off-targets of Ro 48-8071, we synthesized a derivative of Ro 48-8071 that is amenable to click chemistry reactions. Ro 48-8071 contains a photoreactive benzophenone, which upon UV irradiation is predicted to form a reactive triplet diradical that can covalently bind to neighboring amino acids in the bound protein. The terminal alkene group of Ro 48-8071 was replaced with a terminal alkyne (hereafter referred to as "Ro-alkyne"), which serves as a functional handle for click chemistry reactions. After confirming that this Ro-alkyne retained its antiproliferative activity against Mut6 cells (IC), we performed a click chemistry assay to confirm its activity. 50 Intracellular binding partners of Ro-alkyne were analyzed using 10 μM Ro 48-8071 (=0.396 μM). Incubation of cells with 10 μM Ro 48-8071 resulted in the disappearance of multiple probe- and UV-dependent bands. On the other hand, the band corresponding to LSS was only observed after ectopically expressing LSS in HEK293T cells.

[0034] To determine the identities of putative off-targets of Ro 48-8071, affinity purification of Ro-alkyne-binding proteins was performed in the presence or absence of 10 μM Ro 48-8071. In stark contrast to MM0299, 130 proteins were more strongly enriched than Lss (#131, 1.3-fold enrichment) under the Ro-alkyne-only condition, suggesting the involvement of multiple off-targets. Among the most enriched Ro-alkyne-binding proteins, three enzymes involved in the cholesterol biosynthesis pathway were identified: Ebp (#2, 8.4-fold enrichment), Lbr (#5, 3.1-fold enrichment), and Dhcr7 (#7, 2.5-fold enrichment). These results indicate that, unlike MM0299, Ro 48-8071 has multiple off-targets, including several enzymes involved in cholesterol biosynthesis.

[0035] Inhibition of these various sterol biosynthetic enzymes may explain the observed attenuation of EPC increase after LSS inhibition by Ro 48-8071. To evaluate the effects of compound 1 and Ro 48-8071 on these various enzymes, we utilized a small molecule tool that can investigate the intracellular binding profiles of small molecules to several cholesterol biosynthetic enzymes (Theodoropoulos et al., 2020). First, we tested the binding of compound 1 and Ro 48-8071 to EBP. Specifically, HCT116 cells were incubated with 1 μM TASIN-2 (an EBP-specific photoaffinity probe) in the presence or absence of increasing doses of TASIN-30 (an EBP-specific inhibitor), compound 1, or Ro 48-8071, followed by UV treatment and fluorescent dye binding. Consistent with the proteomic data, Ro 48-8071 and TASIN-30 eliminated TASIN-2 (a band migrating at approximately 20 kDa), whereas compound 1 did not. Furthermore, treatment with Ro 48-8071 led to the accumulation of 8,9-dehydrocholesterol (8,9-DHC), a non-canonical sterol that accumulates upon genetic or pharmacological inhibition of EBP (Braverman et al., 1999; Theodoropoulos et al., 2020), whereas treatment with compound 1 had no effect on intracellular 8,9-DHC levels. These data provide evidence that Ro 48-8071 binds to and inhibits intracellular EBP.

[0036] Next, we performed similar experiments using a probe (known as "4C12") specific for 7-dehydrocholesterol reductase (mouse 7-dehydrocholesterol reductase is referred to as "Dhcr7" and human 7-dehydrocholesterol reductase is referred to as "DHCR7") (Theodoropoulos et al., 2020). 4C12 and Ro 48-8071 eliminated the crosslinked band of Dhcr7 migrating at 40 kDa, whereas compound 1 did not eliminate the Dhcr7 probe at any dose tested. Consistent with the results of the inhibition studies, intracellular concentrations of 7-dehydrodesmosterol, a substrate of Dhcr7, were found to accumulate after treatment with Ro 48-8071, but not with compound 1. Compounds targeting EBP or DHCR7 can also inhibit DHCR24, which converts desmosterol to cholesterol (Theodoropoulos et al., 2020) (Wages et al., 2018). Although we did not have the chemical tools to directly assess binding to DHCR24, we analyzed the concentration of desmosterol in cells treated with compound 1 or Ro 48-8071. We observed accumulation of desmosterol in cells treated with high doses of Ro 48-8071, but not in cells treated with compound 1, supporting the hypothesis that Ro 48-8071 also inhibits Dhcr24. These data indicate that although both compound 1 and Ro 48-8071 inhibit Lss, Ro 48-8071 also inhibits the activity of Ebp, Dhcr7, and Dhcr24, exerting greater potency in that order.

[0037] These observations suggest that Ro 48-8071 has a significantly greater number of off-targets than compound 1, and some of these off-targets attenuate the production of EPC, an antiproliferative metabolite. Consequently, even though Ro 48-8071 inhibits LSS, its antiproliferative effect is likely multifactorial. To assess the contribution of EPC to Ro 48-8071-induced toxicity, Ro 48-8071 was incubated with increasing concentrations of NB-598. NB-598 showed a moderate protective effect against Ro 48-8071-induced toxicity (IC value of Ro 48-8071). 50 This protective effect was not dose-dependent and was abolished by high concentrations of NB-598. In contrast, the toxicity of compound 1 was rescued by NB-598 in a dose-dependent manner, with IC 50 increased by up to 11.8 times.

[0038] 5. MM0299 demonstrates efficacy in human GSC lines Because this study of MM0299 was primarily conducted using Mut6 cells, a GSC line derived from a single gene-defined mouse model, we next sought to evaluate the antiproliferative activity and mechanism of action of MM0299 in various human GSC lines with different driver genes. Two patient-derived GSC lines, designated UTSW63 and UTSW71, were constructed at UT Southwestern Medical Center. UTSW63 was derived from a tumor resected from a 71-year-old male patient with a malignant neoplasm of the temporal lobe. Genomic analysis of the resected tumor revealed genomic alterations in bona-fide GBM cancer drivers. The genomic alterations included, as expected, loss of the tumor suppressor TP53 (deletion at 17p13.3-p11.1), loss of the tumor suppressor RB1 (deletion at 13q13.11-q14.3 with a predicted frameshift canonical splice donor site mutation c.1215+1G>A), and amplification of EGFR (93 copies at 7p11.2). UTSW71, derived from a 52-year-old male patient with glioblastoma, harbored alterations in various cancer drivers, including PTEN gene abnormalities (deletion of 10q21.1-q26.3 and P95S mutation) and amplification of regions containing oncogenes: CDK4 (34 copies at 12q13.3-q14.1), MDM2 (89 copies at 12q15), and c-MYC (51 copies at 8q24.13-q24.21).

[0039] Similar to Mut6 cells, both UTSW63 and UTSW71 grow as neurospheres in serum-free medium (data not shown). MM0299 inhibited the growth of both UTSW63 and UTSW71, and the IC 50The IC values ​​were 0.0222 μM and 0.0212 μM, respectively. The toxicity of MM0299 in these two human GSC lines was fully rescued by exogenous MCD-labeled lanosterol or cholesterol. The natural mechanism for extracellular cholesterol uptake is the uptake of circulating low-density lipoprotein (LDL). Therefore, we investigated whether human LDL could rescue the toxicity of MM0299 in human GBM cells. The toxicity of compound 1 was fully rescued by the addition of 20 μg / ml human LDL in both UTSW63 and UTSW71 cells. Furthermore, to investigate the role of the shunt pathway in MM0299 toxicity, we again used the tool compound NB-598. NB-598 was highly toxic to UTSW63 and UTSW71 cells, with IC values ​​of 0.0222 μM and 0.0212 μM in each cell line. 50 The IC values ​​for UTSW63 cells were 5.56 nM and 8.26 nM, respectively. By adding a low dose of NB-598 that does not affect cell proliferation, the IC values ​​for UTSW63 cells were 50 increased 15.0-fold, and IC 50 The 21.9-fold increase in EPC activity in cultured human GSC lines rescued the toxicity of compound 1. These data suggest that compound 1 exerts its effects by upregulating EPCs via the shunt pathway, thereby depleting the intracellular cholesterol pool.

[0040] 6. Analog 13 exhibits bioavailability and is able to cross the blood-brain barrier With the mechanism of action of MM0299 established, we sought to identify and evaluate analogs with brain bioavailability, a prerequisite for in vivo studies in glioblastoma. In vitro and in vivo pharmacological evaluation of a series of analogs (Table 1) identified analog 13 as a candidate molecule for activating the shunt pathway in mouse brain. [ka]

[0041] Analog 13 competes with p75 / LSS (EC 50=0.0287 μM), possesses drug-like physicochemical properties (MW=468 Da, CLogP=4.3, LogP=3.8, tPSA=64), induces EPC upregulation, and retains antiproliferative activity in Mut6 cells (IC 50 =0.0443 μM), and retained antiproliferative activity in the human GSC line UTSW63 (IC 50 =0.0293 μM). Analog 13 was stable in plasma (>24 hours) and showed superior metabolic stability compared to other analogs when incubated with mouse S9 fraction (Table 1). Pharmacokinetic analysis (PK) of analog 13 administered to mice by intravenous injection (IV) at a dose of 5 mg / kg or orally (PO) at a dose of 20 mg / kg showed AUC 経口 / AUC iv ×Dose iv / dose 経口 Oral bioavailability, as defined by the CI, was shown to be 39% in plasma and 58% in brain. Importantly, analogue 13 administered orally at a dose of 20 mg / kg resulted in a total C max 5 μM (2381 ng / ml), brain-free C max 14 nM, and a brain-blood ratio of 1.8 (free AUC 脳 / Free AUC 血漿 This was calculated as the antiproliferative activity against human GSC lines using a concentration of 0.11 in the unbound fraction (fu) measured in the culture medium. 50This is preferable to the previous value (3 nM). Next, we quantified EPC concentrations in plasma and brain after treatment with analog 13 by mass spectrometry. Plasma EPC concentrations increased time-dependently after a single 20 mg / kg dose. Desmosterol was immediately detected in the brain, but EPC was not. Even at the time point when plasma EPC concentrations significantly increased, brain EPC was not detected. Given the expected low cholesterol biosynthetic flux in the adult brain, this may explain the lack of EPC detection. Alternatively, the concentration of analog 13 in the brain may have been insufficient to inhibit LSS, contrary to our expectations. To evaluate these possibilities, we investigated whether EPC could be detected in orthotopic xenograft tumors derived from UTSW63 cells. Twenty-five days after intracranial injection of UTSW63 cells into mice, analog 13 was orally administered at a dose of 20 mg / kg or vehicle for 3 days on a once-daily or twice-daily dosing schedule. After treatment, EPC levels were analyzed and a dose-dependent increase in EPC levels was observed in both serum and GBM tumors. These findings indicate that administration of analog 13 selectively induced EPCs in glioblastoma cells compared with normal brain, and that EPCs can be used as a pharmacodynamic marker to optimize MM0299 for further preclinical evaluation.

[0042] Consideration Our investigation into the mechanism of action of MM0299 has uncovered a novel approach to targeting tumor cellular metabolism for the treatment of brain tumors. Metabolic reprogramming is a fundamental feature of the molecular pathogenesis of gliomas, and numerous therapeutic strategies designed to exploit this process are currently undergoing preclinical and clinical trials (Zhou and Wahl, 2019). One such strategy targets metabolic pathways that exhibit greater flux in glioma cells compared to normal cells. For example, a study evaluating the radiosensitizing effects of inhibiting purine nucleotide synthesis in GBM has been reported (NCT04477200) (Zhou et al., 2020). Another strategy involves inhibiting the synthesis of the oncometabolite 2-hydroxyglutarate, which selectively accumulates in gliomas, leading to the formation of gliomas with mutant isocitrate dehydrogenase (IDH) (NCT02481154) (Mellinghoff et al., 2021). Unlike these strategies, our approach relies on a novel paradigm that activates, rather than inhibits, metabolic pathways in GBM cells to induce the production of tumor-specific cytotoxic metabolites, EPCs.

[0043] Like most cell types, cancer cells regulate their unesterified cholesterol pool by balancing peripheral uptake, synthesis, and catabolism. Therefore, blocking cholesterol synthesis can induce a negative feedback pathway that maintains homeostasis through increased uptake of low-density lipoprotein (LDL). However, LDL particles cannot cross the blood-brain barrier, so the brain must synthesize its own cholesterol. Most cholesterol synthesis in the brain occurs during embryonic development, and the rate of cholesterol synthesis in the adult brain declines sharply (Dietschy, 2009). However, dividing GBM cells have a higher cholesterol requirement than adult neurons, and are predicted to meet the demand for cell proliferation by relying on de novo cholesterol synthesis and the uptake of exogenous cholesterol (synthesized by astrocytes) (Sassi et al., 2021). By inhibiting LSS, we can exploit the difference in cholesterol synthesis flux between normal brain and tumors. Inhibition of LSS would shift sterol flow from cholesterol synthesis to EPC synthesis, thereby inhibiting cell proliferation and resulting in tumors synthesizing more EPCs than normal brain. Consistent with this hypothesis, in vivo administration of analog 13 failed to detect EPC generation in normal brain, but dose-dependently increased EPCs in orthotopic glioblastoma tumors. Therefore, inhibiting cholesterol biosynthesis via LSS inhibition may selectively target GBM, which undergoes rapid division and exhibits increased sterol synthesis.

[0044] There is now evidence that reducing intracellular cholesterol pools can slow glioblastoma progression. The synthetic LXR agonists GW3965 and LXR-623 promote cholesterol efflux and reduce intracellular cholesterol pools in GBM cells by upregulating the expression of the cholesterol transporter ABCA1 (Guo et al., 2011; Villa et al., 2016). Accordingly, LXR-623 is brain-permeable, delays orthotopic glioblastoma tumor progression, and extends overall survival in glioblastoma tumor-bearing mice (Villa et al., 2016). However, adverse events related to the mechanism of action have hindered clinical development of LXR agonists for the treatment of glioblastoma and other indications. For example, LXR agonists have been reported to stimulate fatty acid synthesis, increasing circulating triglyceride concentrations to clinically unacceptable levels and accelerating the development of fatty liver disease ( Schultz et al., 2000 ; Joseph et al., 2002 ; Bradley et al., 2007 ).

[0045] Another approach to lowering cholesterol levels in GBM cells is to use inhibitors of enzymes crucial to the sterol biosynthesis pathway. Intracellular cholesterol levels are regulated within narrow ranges at the synthesis, LDL uptake, and catabolism (or excretion) stages. Decreased cholesterol levels are detected by the SREBP cleavage-activating protein (SCAP), which promotes the proteolytic cleavage and activation of SREBP-2 (Brown et al., 2018). Activated SREBP-2 is transported to the nucleus and promotes the transcription of genes required for cholesterol synthesis and cholesterol uptake. These feedback pathways therefore counteract the cholesterol-lowering effects of most cholesterol biosynthesis enzyme inhibitors (Brown et al., 1978).

[0046] Inhibition of lanosterol synthase (LSS) is unique in that it can suppress cholesterol synthesis without stimulating these negative feedback pathways. LSS converts linear oxidosqualene to lanosterol, which is the first sterol ring-containing intermediate in cholesterol biosynthesis. Unlike other enzymes in the cholesterol biosynthetic pathway after squalene synthesis, LSS inhibition can inhibit cholesterol synthesis without causing the accumulation of sterol intermediates. Partial inhibition of LSS diverts sterol flow to a "shunt" pathway, inducing the synthesis of the noncanonical sterol EPC. The accumulation of EPC induces a feedback mechanism that inhibits SREBP activation, thereby preventing the upregulation of genes promoting de novo cholesterol biosynthesis and cholesterol uptake in cells (Radhakrishnan et al., 2007). Furthermore, EPC is a potent modulator of LXR, a nuclear hormone transcription factor whose activation induces cholesterol metabolism and efflux (Janowski et al., 1996; Janowski et al., 1999). As a ligand for endogenous LXR, EPC does not induce fatty acid synthesis (Rowe et al., 2003), and LSS inhibitors do not exhibit the adverse effects seen with synthetic LXR agonists in animals. Therefore, LSS inhibition can reduce intracellular cholesterol pools in various ways, including directly inhibiting de novo cholesterol synthesis, inhibiting the feedback pathway that promotes cholesterol biosynthesis, and promoting efflux via LXR activation. This study demonstrated that EPC synthesis via the shunt pathway was necessary and sufficient for the suppression of glioblastoma cell proliferation by the LSS inhibitor MM0299.

[0047] Furthermore, recent evidence suggests that LSS is a potential target for glioblastoma. Allis et al. reported that MI-2, a small molecule LSS inhibitor that increases EPC levels, exhibited antiproliferative activity in glioma. MI-2 has previously been reported to inhibit the protein-protein interaction between menin and MLL, which are important epigenetic regulators in leukemia (Grembecka et al., 2012; Shi et al., 2012). However, MI-2 activity in glioma was not mediated by menin or MLL but rather by direct inhibition of LSS. These findings by Allis et al. not only demonstrated LSS as a potential target for GBM, but also supported the importance of ongoing target deconvolution for compounds evaluated in cancer preclinical trials (Phillips et al., 2019).

[0048] Most LSS inhibitors have been developed to treat atherosclerosis, primarily to lower LDL levels, with little data supporting their efficacy against cancer. One limitation in the development of LSS inhibitors is the difficulty in assessing LSS selectivity. Indeed, most reported small-molecule LSS inhibitors are amphipathic amine drugs, which bind to numerous other proteins, including several enzymes in the cholesterol biosynthetic pathway after squalene synthesis (Rabelo et al., 2017). This polypharmacology is most evident in LSSs, EBPs, and the sterol reductases DHCR7, DHCR14, and DHCR24 (Wages et al., 2018; Korade et al., 2016; Moebius et al., 1998). These enzymes share a common need to stabilize the carbocation charge generated during the conversion of highly lipophilic sterols. This likely explains why amphipathic amines, which are protonated at physiological pH, are able to bind to all or some of these enzymes. Due to the similar substrate structures and the physical proximity of these enzymes, photochemical probes that attribute binding and activity to specific cholesterol biosynthetic enzymes have proven to be useful tools for investigating these enzymes (Theodoropoulos et al., 2020). Using these photochemical probes in conjunction with sterol mass spectrometry, we compared the selectivity of MM0299 with that of Ro 48-8071, an LSS inhibitor that has already been extensively characterized. Our studies demonstrated that Ro 48-8071 binds to and inhibits LSS, but also binds to multiple off-targets, inhibiting multiple enzymes in the cholesterol pathway, including EBP and DHCR7, ultimately impairing EPC production. Similar off-target investigations of MM0299 revealed no off-targets or evidence of binding to or inhibition of other cholesterol biosynthetic enzymes.

[0049] Our research supports LSS as a target for glioblastoma and identifies MM0299 as a highly selective LSS inhibitor. In addition to the aforementioned cholesterol-lowering effects, EPCs have also been shown to stimulate oligodendrocyte myelination via an unknown mechanism (Hubler et al., 2021) and promote midbrain dopaminergic neurogenesis via LXR activation (Theofilopoulos et al., 2013; Theofilopoulos et al., 2019). Among neurodegenerative diseases, multiple sclerosis (MS) develops due to neuronal demyelination, and Parkinson's disease (PD) develops due to the loss of midbrain dopaminergic neurons. Novel treatments for these diseases are needed, and brain-permeable MM0299 derivatives capable of inducing EPC generation may be clinically useful in these diseases.

[0050] A major challenge in developing treatments for GBM and other neurological disorders is identifying small molecule drugs that can cross the blood-brain barrier. Herein, we describe MM0299 derivatives, which are blood-brain barrier-permeable drugs that are orally bioavailable. These derivatives increase EPCs in orthotopic xenograft tumors but not in normal brain.

[0053] synthesis All reactions were carried out under anhydrous conditions using dry solvents under a nitrogen atmosphere unless otherwise noted. Anhydrous solvents were obtained by passing through commercially available alumina columns (Innovative Technology, Massachusetts). All reagents were the highest purity commercially available compounds. Analytical thin-layer chromatography (TLC) was performed on aluminum plates coated with Merck Silica Gel 60F254 and visualized by ultraviolet irradiation (254 nm) or staining with potassium permanganate solution. Flash column chromatography was performed under pressure using Merck Silica Gel 60 (230-400 mesh). Infrared spectra were measured on thin films mounted on NaCl glass using a Perkin-Elmer I1000 FTIR series. Optical rotations were measured at 20 °C using a Rudolph Research Analytical Autopol® IV polarimeter. 1 H NMR spectra were measured using a 400 MHz Varian Inova-400 spectrometer in CDCl3, CD3OD, DMSOd6, or (CD3)2CO solvents, with the residual proton in the solvent as the internal standard (CDCl3, d H = 7.26 ppm; (CD3)2CO, d H = 2.05 ppm; CD3OD, d H = 3.31 ppm; DMSO-d6, d H = 2.50 ppm) and recorded at ambient temperature. Chemical shifts (d) are expressed in parts per million (ppm) and coupling constants (J) are expressed in Hertz (Hz). Proton spectra are reported as d (multiplicity, coupling constant J, number of protons). Multiplicities are indicated by the following abbreviations: app = apparent, b = broad, d = doublet, dd = doublet of doublets, ddd = doublet of doublet of doublets, dddd = doublet of doublet of doublet of doublets, m = multiplet, s = singlet, t = triplet. 13 C NMR spectra were obtained using the same type of spectrometer at 100 MHz in CDCl3, CD3OD, DMSO-d6, or (CD3)2CO solvents. C=77.0 ppm), CD3OD(d C =49.0 ppm), DMSO-d6 (d C =39.4 ppm) or (CD3)2CO(d C The central peak (A = 30.8 ppm) was used as an internal standard and recorded at ambient temperature. Electrospray ionization mass spectra (ESI-MS) were recorded using a Shimadzu 2010-LCMS. HRMS was performed using a Shimadzu IT-TOF. Microwave reactions were performed using a Biotage® Initiator Classic. The following abbreviations are used: DMAP = 4-(dimethylamino)pyridine, DMF = N,N-dimethylformamide, DIPEA = N,N-diisopropylethylamine, DHP = tetrahydro-2H-pyran, EDC = N-ethylcarbodiimide hydrochloride, HATU = 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium 3-oxide hexafluorophosphate, MW = microwave, NMP = 1-methyl-2-pyrrolidinone, py = pyridine, TBDMS = tert-butyldimethylsilyl, THF = tetrahydrofuran, THP = 3,4-dihydro-2H-pyran.
