Abstract
Description
A RhoA inhibitor compound, a pharmaceutical composition and its application Technical Field
[0001] This invention relates to the field of biomedical technology, and in particular to a novel covalent inhibitor compound of RhoA wild-type or pathogenic mutants, pharmaceutical compositions and their applications. Background Technology
[0002] RAS superfamily proteins catalyze the hydrolysis of GTP and regulate their activation and inhibition within the cell by switching between GTP / GDP binding states, acting as molecular switches in the cell. Based on structural and functional similarity, RAS superfamily proteins can be divided into five subfamilies: RAS, Rho, Rab, Arf, and Ran, containing more than 170 members.
[0003] RAS protein is the best-understood small G protein to date. KRAS gene mutations account for over 80% of all RAS gene mutations, with mutations concentrated in key locations such as the p-loop and switch. In pancreatic ductal carcinoma, KRAS is the predominant mutation. G12D Mutations, and the main mutation type in non-small cell lung cancer is KRAS. G12C Currently, it is generally believed that mutations at the G12, G13, and Q61 sites of the RAS protein disrupt both the endogenous substrate hydrolysis activity of the RAS protein and the substrate hydrolysis activity of the RAS protein catalyzed by GAP proteins, placing the RAS protein in a GTP-binding activated state. However, the extremely strong affinity of small G proteins for the substrate GTP / GDP, and the fact that they have no other binding pockets besides the substrate pocket, pose significant challenges to the design of small molecules targeting small G proteins, severely limiting their development. Small molecule inhibitors such as sotarasib and adagrasib are considered first-generation targets for KRAS. G12C While covalent small molecule drugs bring hope to patients, they have also sparked debate regarding the targeting of KRAS. G12D The development of next-generation small molecules and other mutants.
[0004] Rho proteins are the second largest members of the RAS superfamily and regulate downstream signaling pathways, influencing cell morphology, cytoskeleton formation, cell cycle, and cell migration. RhoA, upon GTP activation, binds to and activates the downstream serine / threonine kinase ROCK. Activated ROCK phosphorylates myosin light chain phosphatase, promoting actin-myosin cross-linking to facilitate kinase contraction. It also activates filament-cleaving proteins and enhances actin filament stability, thereby affecting cytoskeleton formation, focal adhesion assembly, and cell migration. Furthermore, Rho protein expression can promote cell cycle progression from G1 to S phase; this function may be related to the regulation of cell cycle-related proteins.
[0005] RhoA mutations have been found in various cancers, and compared to RAS protein, RhoA has a greater variety of pathogenic mutations, with significant differences in activity characteristics among different mutants. In angioimmunoblastic T-cell lymphoma, the most common RhoA mutants detected are G17V mutations. G17V The mutants lose their GDP / GTP binding ability, leading to RhoA function suppression. This impaired RhoA function, combined with TET2 deficiency, is a major cause of AITL-specific pathogenesis. Approximately 20% of RhoA mutations are found in diffuse gastric cancer, with Y42C being a hotspot mutation. Y42C mutations weaken RhoA's ability to hydrolyze GTP and are considered a functionally gaining mutation. About 15% of mutations are also found in adult T-cell lymphomas, distributed near the GDP binding pocket. These mutations include C16 mutations (C16R, C16F, C16G, C16L), G17 mutations (G17V, G17E, G17R), K118 mutations (K118Q, K118E), and A161 mutations (A161P, A161V, A161E), with C16R mutations having the highest frequency. The G17V and A161E mutants cannot bind to the substrate GDP / GTP, while mutants such as C16R, C16F, K118E, A161P, and A161V exhibit decreased affinity for GTP / GDP and an accelerated rate of endogenous substrate exchange, thus being termed "fast-circulating mutants." Furthermore, RhoA mutations also exist in head and neck squamous cell carcinoma, with the mutation site concentrated at glutamate 40, and the mutation type being E40Q. Due to the high correlation between RhoA protein mutations and various cancers, RhoA has become an important drug target.
[0006] RhoA, which also belongs to the small G protein family, is also a recognized "difficult target protein." However, the lack of in-depth research on the structure, function, and regulatory mechanism of RhoA has limited the development of inhibitors targeting the RhoA pathway.
[0007] Currently reported small molecule inhibitors mainly include: covalent inhibitors targeting cysteine residues of RhoAC107, represented by DC-Rhoin (Adv. Sci., 2020, 7(14), 2000098.), and protein-protein interaction inhibitors targeting the RhoA-GEF interaction interface, represented by Rhosin (Chem. Biol., 2012, 19(6), 699.). However, research on these small molecule inhibitors is limited to wild-type or artificially mutated RhoA proteins. Currently, there are no reports on drug research targeting pathogenic mutants of RhoA. Therefore, developing novel small molecule inhibitors targeting clinically pathogenic mutants of RhoA is of great significance. Summary of the Invention

[0093] This invention is also intended to include crystal forms of the compounds of this invention, such as hydrates, solvates, etc.
[0094] This invention is also intended to include esters, prodrugs, or metabolites of the compounds of this invention.
[0095] Some compounds of this invention may exist in specific geometric or stereoisomeric forms. This invention covers all compounds, including their cis and trans isomers, R and S enantiomers, diastereomers, (D) isomers, (L) isomers, racemic mixtures, and other mixtures. Additionally, the asymmetric carbon atom may represent a substituent, such as an alkyl group. All isomers and mixtures thereof are included in this invention.
[0096] According to the present invention, the ratio of isomers in a mixture of isomers can be varied. For example, a mixture containing only two isomers can have the following combinations: 50:50, 60:40, 70:30, 80:20, 90:10, 95:5, 96:4, 97:3, 98:2, 99:1, or 100:0.

Tritium, i.e. 3 H and carbon-14, i.e. 14 C, their preparation and detection are relatively easy. They are the preferred isotopes. In addition, heavier isotopes such as deuterium are used for substitution. 2 H, due to its excellent metabolic stability, offers advantages in certain therapies, such as increasing half-life or reducing dosage in vivo, and therefore may be preferred in some cases. Isotopically labeled compounds can be prepared using general methods, by replacing the non-isotopic reagent with an readily available isotopically labeled reagent, according to the scheme described in the examples.

[0424] Example 121: Mant-GDP Exchange Experiment
[0425] Using EDTA to chelate Mg 2+This can accelerate the substrate exchange rate of RhoA. In a system containing excess EDTA, the addition of fluorescently labeled substrates (mant-GDP / -GTP / -GMPPMP / -GTPγS, etc.) allows the labeled substrates to bind into the RhoA substrate pocket, resulting in enhanced fluorescence intensity. Therefore, the level of inhibition of the RhoA substrate exchange process by small molecules can be detected by measuring the amplitude of the fluorescence signal change.
[0426] This patent uses RhoAWT and RhoA Y42C RhoA A161P The inhibitory activity of small molecule compounds against wild-type and mutant RhoA proteins was tested using mutants. 0.5–2 μM RhoA protein was incubated with the compounds for 30 min, followed by the addition of twice the volume of Mg. 2+ Fluorescence signal changes were immediately detected using mant-GDP at concentrations of EDTA (1000 ppm) and RhoA (2 times the concentration). DMSO was used as a control group, and the inhibition rate was calculated based on the magnitude of signal changes in the experimental groups. RhoA... A161P Due to decreased substrate affinity, in the presence of Mg 2+ The substrate exchange rate is relatively fast in the system, so EDTA is not added during the test.
[0427] Fitting IC using this method 50 At the same time, with a fixed RhoA concentration of 1 μM, 11-12 compound concentration gradients were set up using 2-fold serial dilutions, with 3 replicates for each concentration gradient. The inhibitory activity against RhoA protein was calculated based on the inhibition rate of each compound concentration gradient, and the IC50 was fitted. 50 Because small molecules react with different RhoAWT and RhoA... Y42C and RhoA A161P The activities differ, using RhoAWT and RhoA Y42C Test IC 50 The highest concentration of the compound was set at 512 μM, and RhoA was tested. A161P The maximum concentration of the compound was set to 120 μM.
[0428] The bioactivity assay of the compounds disclosed herein is for RhoA A161P The inhibitory activity of the protein substrate exchange was classified into four levels based on the level of inhibition of the substrate exchange process at a concentration of 30 μM. Among them, A represents an inhibition rate ≥90% at 30 μM; B represents an inhibition rate ≥75% at 30 μM (90% > 75%); C represents an inhibition rate ≥50% at 30 μM (75% > 50%); and D represents an inhibition rate <50% at 30 μM.
