Description

[Technical field]

[0001] cross reference This application claims the benefit of U.S. Provisional Patent Application No. 63 / 184,710, filed May 5, 2021, and U.S. Provisional Patent Application No. 63 / 320,991, filed March 17, 2022, the contents of which are incorporated by reference in their entireties herein.

[0002] The present disclosure relates to SHP2 inhibitors and methods of treating cancer. [Background technology]

[0003] Cancer is a leading cause of morbidity and mortality worldwide. Although standard therapies for various cancer types have improved significantly over the years, current standard therapies still do not meet the need for effective therapies to improve cancer treatment. Protein tyrosine phosphatase 2 (SHP2) belongs to the protein tyrosine phosphatase family, which is involved in regulating cell proliferation, survival, differentiation, migration and apoptosis. In the protein tyrosine phosphatase superfamily, SHP2 is the first identified true proto-oncogene and plays a key role in various signaling pathways such as metabolism, differentiation, proliferation, migration and survival. SHP2 can regulate Ras mitogen-activated protein kinase, Janus kinase-signal transducer and activator of transcription (JAK-STAT) or phosphoinositide 3-kinase-AKT and nuclear factor kappa B (NF-kappa B) and other signaling pathways. SHP2 is also a master regulator of the programmed cell death protein-1 (PD-1) and B and T lymphocyte attenuation factor (BTLA) immune checkpoint signaling pathways, which may be related to tumor immunosuppression. Moreover, SHP2 mutations occur rarely in tumors.

[0004] In recent years, SHP2 has been shown to play an important role in tumor inhibition, and the role of SHP2 in tumors in particular has become increasingly evident. Therefore, inhibition of SHP2 has become a viable antitumor strategy. As cancers become resistant or refractory, new treatments remain necessary. Summary of the Invention

The compounds presented herein include all diastereomeric, enantiomeric, and epimeric forms, and appropriate mixtures thereof. The compounds and methods provided herein include all cis-, trans-, syn-, anti-, entgegen (E), and zusammen (Z) isomers, and appropriate mixtures thereof. In certain embodiments, the compounds described herein are prepared as individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds / salts, separating the diastereomers, and recovering the optically pure enantiomers. In some embodiments, the resolution of the enantiomers is carried out using covalent diastereomeric derivatives of the compounds described herein.

In other embodiments, separation of stereoisomers is accomplished by chromatography, or by formation of diastereomeric salts and separation by recrystallization, or chromatography, or any combination thereof. Jean Jacques, Andre Collet, Samuel H. Wilen, "Enantiomers, Racemates and Resolutions," John Wiley and Sons, Inc., 1981. In some embodiments, stereoisomers are obtained by stereoselective synthesis.

[0049] In some embodiments, the compounds described herein are prepared as prodrugs. A "prodrug" refers to an agent that is converted to the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be administered more easily than the parent drug. For example, a prodrug may be bioavailable for oral administration, whereas the parent drug is not. A prodrug may also have improved solubility in pharmaceutical compositions compared to the parent drug. In some embodiments, the design of a prodrug increases the effective water solubility. A non-limiting example of a prodrug is a compound described herein that is administered as an ester ("prodrug") to facilitate crossing cell membranes where water solubility is disadvantageous for mobility, but is metabolically hydrolyzed to the active entity, a carboxylic acid, once inside a cell where water solubility is beneficial. A further example of a prodrug may be a short peptide (polyamino acid) bonded to an acid group, which is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, the prodrug is chemically converted to the biologically, pharma- ceutical, or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharma- ceutical or therapeutically active form of the compound.

[0050] In some embodiments, prodrugs are designed to alter the metabolic stability or transport properties of a drug, mask side effects or toxicity, improve the taste of a drug, or change other properties or characteristics of a drug. Knowledge of in vivo pharmacokinetic and pharmacodynamic processes and drug metabolism allows for the design of prodrugs of a compound once a pharmacologic active compound is known. (See, e.g., Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392; Silverman (1992), The Organic Chemistry of Drug Design and Drug Action, Academic Press, Inc., San Diego, pages 352-401, Rooseboom et al., Pharmacological Reviews, 56:53-102, 2004; Aesop Cho, "Recent Advances in Oral Prodrug Discovery", Annual Reports in Medicinal Chemistry, Vol. 41, 395-407, 2006; T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the ACS Symposium Series).

[0165] Cytokine detection assay: A V-Plex Proinflammatory Panel 1 Mouse Kit (Mesoscale Discovery) was used to determine cytokine levels in plasma isolated from tumor-bearing animals 2 hours after the last dose. Plasma from tumor-bearing animals was analyzed as described in the manufacturer's guidelines. Briefly, diluted plasma is introduced to MSD plates pre-coated with capture antibodies against KC / GRO. After incubation, samples are washed and incubated with a secondary detection antibody (MSD SULFO-TAG™). Electrochemiluminescence detection from the assay is analyzed on the Meso Scale Discovery platform and cytokine levels are calculated according to the manufacturer's control samples. The results of this experiment are shown in Figure 11 - Compound of formula (Ia) was observed to significantly reduce KC / GRO compared to GH21001 (TNO-155) and RMC-4550.

[0166] Immunoblot analysis: Tumors were harvested at each time point after administration and flash frozen in liquid nitrogen. Tissues were ground in liquid nitrogen using a mortar and pestle and weighed. An amount of RIPA buffer containing phosphatase and protease inhibitors was added at three times the weight, and samples were inverted and placed on ice for 30 min. Cell lysates were obtained by centrifugation at 14,000g for 15 min at 4°C, and the supernatant was transferred to a new tube. Protein was quantified using the Pierce BCA Protein Assay Kit. 50 μg of protein was loaded into each well. Gels were transferred to pre-activated PVDF, and primary and secondary antibodies were diluted in TBST containing 5% milk powder. Target proteins were detected with a Tanon 5200 chemiluminescence imaging analysis system using the ECL method. Primary antibodies: DUSP6, Abcam ab76310, β-actin CST 3700S, p-ERK CST 4370s, ERK CST 4695s. The results of these experiments in the HCC827 CDX xenograft model are shown in Figures 13A, 13B, and 13C. Also see Figures 13E and 13F. In the HCC827_ER1 CDX xenograft model, the results are shown in Figures 14A and 14B.

[0167] qPCR Analysis: Tumor tissue was harvested 4 hours after administration and the tissue was snap frozen in liquid nitrogen. The tissue was ground in liquid nitrogen using a mortar and pestle and weighed. The tissue was placed in RLT buffer containing stainless steel beads and placed in a TissueLyser. RNA was processed using an RNAeasy mini spin kit (Qiagen 74106). Total RNA was quantified by Nanodrop™ 2000 spectrophotometer. cDNA was prepared using the High Capacity cDNA Reverse Transcriptase Kit (ABI 4374966). Real-time PCR was performed using an Applied Biosystems Inc,fact PCR system 7900H using TaqMan Universal PCR Master Mix (ABI 4304437) and DUSP6 probe (Thermo Fisher 4331182) and GAPDH probe (ThermoFisher 4351370). Raw data was analyzed by SDS2.4 and processed using the ΔCt relative quantification method. ΔCt values ​​were calculated relative to the human housekeeping gene GAPDH. ΔΔCt values ​​were calculated relative to the vehicle group. 2 -ΔΔCt represents the target gene, DUSP6, expression level. The results of these experiments in the HCC827 CDX xenograft model for DUSP6 expression are shown in Figure 13D, Figure 13G.

[0168] Pharmacokinetic analysis: Blood and tumor were collected from tumor-bearing animals at each time point after a single dose of HBI-2376 at each dose concentration, N=3 / time point (plasma) or N=3 / time point (tumor tissue). Samples were analyzed by LC-MS / MS analysis using Phoenix WinNonlin 6.3 to determine the concentration of compound in plasma or tumor samples. Concentrations were calculated using the linear / logarithmic trapezoidal rule. The results of these experiments in the HCC827 CDX xenograft model are shown in Figure 15A and Figure 15B.
