Abstract
Description
Technical Field
[0001] This disclosure provides bridged diazaspirocyclic compounds that inhibit the interaction of menin with MLL and MLL fusion proteins. This disclosure also provides methods for preparing these compounds, pharmaceutical compositions comprising these compounds, and their use for the prevention or treatment of cancer and other diseases mediated by the interaction of menin with MLL and / or MLL fusion proteins. background
[0002] Mixed lineage leukemia (MLL, also known as MLL1 or KMT2A) gene rearrangements occur in approximately 10% of acute leukemias and are particularly prevalent in infantile acute leukemia, accounting for up to ~70% of infantile acute lymphoblastic leukemia (ALL) cases (Issa, GC et al., Leukemia, 2021, 35, 2482). MLLr (MLL rearrangement) is also found in 85% of secondary acute myeloid (AML) leukemia cases, occurring in patients treated with topoisomerase II inhibitors. More than 80 partner genes are involved in MLL fusions, and six major partner genes account for approximately 80% of cases, including AF4 (ALL-1 fusion gene from chromosome 4), AF6, AF9, AF10, ENL (11-19 leukemia), and ELL (11-19 lysine-rich leukemia) (Meyer, C. et al., 2018, Leukemia, 32, 273). MLL translocation leads to the expression of MLL fusion proteins, which enhance proliferation and block hematopoietic differentiation, ultimately driving the development of leukemia. MLLr leukemia is one of the high-risk types of leukemia, characterized by its aggressiveness, treatment resistance, high frequency of early relapse, and a 5-year survival rate of only about 35% (Marschalek, R. Br J Haematol. 2011, 152, 141). Therefore, there is a huge unmet medical need for treatment of MLLr leukemia.
[0003] The protein-protein interaction (PPI) between menin and MLLr is crucial to the pathogenesis of MLLr-driven leukemia through dysregulation of the HOXA and MEIS1 genes. On the other hand, recent studies have revealed the importance of the menin-MLL1 wild-type (wt) interaction in AML with nucleophosphoprotein 1 (NPM1) gene mutations. NPM1 mutations (NMP1c) are found in over 30% of AML patients with poor 5-year overall survival and are also associated with upregulated expression of the HOXA and MEIS1 genes (Kuhn, MW, et al., Cancer Discov. 2016, 6, 1166). Menin inhibitors have been reported to block the interaction between menin and MLLr and MLL wt, demonstrating their potential use in the treatment of MLLr-related acute leukemia and NPM-mutant AML (Klossowski, S., et al., J Clin Invest. 2020, 130, 981).

[0247] General synthetic methods
[0248] Compounds of the examples having a general structure such as A10 can be synthesized according to process 1. The reaction of phenol A1 and 5-bromopyrimidine under basic conditions yields diaryl ether A2, which can be converted to N-oxide A3 in the presence of mCPBA. The subsequent reaction of the latter with a chlorinating agent such as POCl3 conveniently yields chloropyrimidine A4. A nucleophilic substitution reaction between chloride A4 and monoprotected spirodiamine A5 yields the key intermediate A6. Subsequently, deprotection occurs, forming an amide with the N-protected cyclic amino acid A8, and N-deprotection of A9 yields the final compound A10.
[0249] Process 1
[0250]
[0251] Compounds of the examples having a general structure such as C6 can be synthesized according to procedure 2. A selective nucleophilic substitution reaction between a monoprotected bridged spirodiamine A5 and 3,5,6-trichloro-1,2,4-triazine C1 yields triazine C2. A second nucleophilic substitution with phenol C3 yields a monohydrate C4. Removal of the chlorine atom under reducing conditions yields triazine C5. Again, deprotection is subsequently performed, followed by amidation with an N-protected cyclic amino acid A8, and finally N-deprotection to give compound C6.
[0252] Process 2
[0253]
[0254] Examples of compounds having a general formula such as C7 / C8 can be synthesized according to procedure 3. After deprotection, C5 / A7 reacts with A9, A10 or A11 (Ns is 4-nitrobenzene-1-sulfonyl) to give compound C7 / C8.

[0388]
[0389] The antiproliferative activity of the test compounds was evaluated in human leukemia cell lines. Cell lines expressing the MLL fusion proteins MLL-AF4 and MLL-AF9, and carrying the NPM1c gene mutation, MV4-11, MOLM13, and OCI-AML3, were tested separately. HL-60 was used as a control cell line containing two wild-type MLL alleles to exclude compounds exhibiting broad cytotoxic effects. MV4-11 cells were cultured in IMDM supplemented with 10% FBS, MOLM13 and OCI-AML3 cells were cultured in RPMI1640 supplemented with 20% FBS, and HL-60 cells were cultured in IMDM supplemented with 20% FBS. The corresponding cell lines (MV4-11, MOLM13, OCI-AML3, or HL-60) were seeded in 96-well plates (white-walled clear bottom, tissue culture treated, Corning, catalog number CLS3903; batch number 30419025) at 100 μL of medium per well. The plate was placed in a CO2 incubator overnight. Compound solutions (2 mM starting, 4-fold serial dilutions) were prepared and added to wells containing 100 μL of medium with HPD300 according to the well distribution map, and centrifuged at 1000 rpm for 1 minute (total 200-fold dilution). MV4-11, MOLM13, OCI-AML3, and HL-60 cells were incubated with the compound at 5% CO2 and 37°C for 4, 12, 5, and 4 days, respectively. 100 μL of CellTiter-Glo reagent (Promega, catalog number G7573, catalog number 0000416710) was added to the assay plate using a Multirop Combi instrument, and the contents were mixed on a oscillator for 10 minutes to induce cell lysis. After incubation at room temperature for 10 minutes, the transparent bottom was affixed with a white back seal, and the luminescence was read using Envision.
[0390] The test results for the compounds of this invention are shown in Table 1.

[0392]
[0393] 3. Particle stability study
[0394] The study was conducted using liver microsomes (Corning, 0.5 mg / mL). A 10 mM stock solution of the test compound was prepared in DMSO. Aliquots of the stock solution were diluted to 0.5 mM with acetonitrile, and then further diluted to 1.5 μM upon addition of liver microsomes / buffer. 30 μL of the 1.5 μM solution was mixed with 15 μL of 6 mM NADPH, preheated to 37 °C, to a final NADPH concentration of 2 mM. The final concentrations of the test compound and ketoselin were 1 μM. The plates were kept in a 37 °C water bath during the experiment. At each time point (0, 5, 15, 30, 45 min), 135 μL of acetonitrile was added to the corresponding well. After quenching with acetonitrile at the last time point, the plate was shaken for 10 min (600 rpm / min) on an IKA (MTS2 / 4) and then centrifuged at 5,594 g for 15 min (Thermo Multifuge × 3R). Aliquots of the supernatant were diluted 1:1 in distilled water and analyzed by LC-MS / MS. The peak area-to-internal-standard response ratio (PARR) of the compound at 5, 15, 30, and 45 minutes was compared with the PARR at 0 minutes to determine the percentage of the test compound remaining at each time point. The half-life was calculated using Excel software and fitted to a single-phase exponential decay equation.
[0395] 4. hERG inhibition research
[0396] The inhibitory effect of the test compounds on hERG was investigated in CHO-hERG cells (cell density: 21.5 × 10⁶ / mL). 10 μL of the compound stock solution was added to 20 μL of DMSO solution, and then serially diluted 3-fold to six concentrations. Six different concentrations of the compound solution (4 μL) were added to extracellular solution (996 μL) and diluted to the final test concentration (a total of 250-fold dilutions). The highest test concentration was 40.00 μM, followed by 40.0, 13.3, 4.4, 1.48, 0.49, and 0.16 μM. The DMSO content in the final test concentration did not exceed 0.2%, at which point DMSO had no effect on hERG potassium channels. High-resistance sealing of single cells and formation of whole-cell models were both automated using a Qpatch instrument.
