Description

Detailed Description of the Invention

[0001] This application claims the following priority: CN2021105302756, with a filing date of May 14, 2021; CN202111463413X, with a filing date of December 2, 2021.

[0002] [Technical Field] The present invention relates to a series of alkyl carboxylic acid compounds and their uses, specifically to the compounds represented by formula (II) and their pharmaceutically acceptable salts.

[0003] [Background Art] Soluble guanylate cyclase (sGC) is a receptor enzyme for nitric oxide (NO), a second messenger, and is widely present in several cell types such as muscle, epithelial, neuron, and endothelial cells. sGC is a heterodimer in which an α1 or α2 subunit is bound to a β1 subunit containing a heme-deficient molecular family, and is an important signaling enzyme in the NO-sGC-cGMP signaling pathway. Under physiological conditions, NO binds to the heme-deficient molecular family of sGC and, when activated, catalyzes the conversion of guanosine-5'-triphosphate (GTP) to cyclic guanosine monophosphate (cGMP).

[0004] cGMP is an important secondary messenger molecule that activates a series of downstream cascade reactions by activating various downstream effector molecules such as phosphodiesterase (PDE), cyclic nucleotide-dependent ion channel (CNG), and protein kinase (PKG), and plays important physiological functions in the gastrointestinal system, blood circulation system, and nervous system, such as promoting vasodilation and smooth muscle relaxation, inhibiting platelet aggregation, vascular remodeling, cell apoptosis and inflammation, and participating in neurotransmission. Therefore, sGC stimulants can be used as potential treatments for cardiovascular diseases (heart failure, pulmonary hypertension, angina pectoris, myocardial infarction) and fibrotic diseases (renal fibrosis, systemic sclerosis). Under the above pathological conditions, due to long-term oxidative stress, the heme-deficient molecular family of sGC is oxidized (from the ferrous state to the ferric state), and the sGC enzyme cannot be activated by NO, which may promote the deterioration of the disease. Furthermore, it causes diseases such as endothelial dysfunction, atherosclerosis, hypertension, stable or unstable angina pectoris, thrombosis, myocardial infarction, stroke, or exacerbation of erectile dysfunction. Therefore, by activating oxidized sGC to generate cGMP, the treatment and / or prevention of such diseases becomes possible.

[0005] sGC activators are independent of NO and also independent of the heme-deficient molecular family, and can directly activate the sGC-cGMP signaling pathway. This may bring benefits to many diseases caused particularly by defects in NO pathway signaling after oxidative stress.

[0006] In response to the current unmet market and clinical needs for such soluble guanylate cyclase stimulants, the present invention provides a new class of compounds. Such compounds function as activators of soluble guanylate cyclase, have excellent in vitro stimulating activity against soluble guanylate cyclase, and have good pharmacokinetic properties.

[0085] Unless otherwise specified, the term "halo" or "halogen" means, by itself or as part of another substituent, a fluorine, chlorine, bromine, or iodine atom. The compounds of the present invention can exist in specific forms. Unless otherwise specified, the term "tautomer" or "tautomeric form" refers to isomers of different functional groups that are in dynamic equilibrium at room temperature and can rapidly interconvert. If tautomers are possible (e.g., in solution), the chemical equilibrium of the tautomers can be achieved. For example, proton tautomers (also called prototropic tautomers) include interconversions via the movement of protons, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers include interconversions by the recombination of some bonding electrons. Among them, a specific example of keto-enol tautomerization is the interconversion between the two tautomers of pentane-2,4-dione and 4-hydroxypent-3-en-2-one.

[0086] Unless otherwise specified, the terms "enriched in one isomer", "enriched in isomers", "enriched in one enantiomer", or "enriched in enantiomers" mean that the content of one of the isomers or enantiomers is less than 100%, and the content of this isomer or enantiomer is 60% or more, or 70% or more, or 80% or more, or 90% or more, or 95% or more, or 96% or more, or 97% or more, or 98% or more, or 99% or more, or 99.5% or more, or 99.6% or more, or 99.7% or more, or 99.8% or more, or 99.9% or more.

[0087] Unless otherwise specified, the term "isomer excess" or "enantiomer excess" refers to the difference between the relative percentages of two isomers or two enantiomers. For example, when the content of one isomer or enantiomer is 90% and the content of the other isomer or enantiomer is 10%, the isomer or enantiomer excess (ee value) is 80%.

[0088] The optically active (R)- and (S)-isomers, as well as D and L isomers, can be prepared by chiral synthesis or by chiral reagents or other conventional techniques. To obtain one enantiomer of a compound of the present invention, it can be prepared by asymmetric synthesis or derivatization with a chiral auxiliary, where the resulting mixture of diastereomers is separated and the auxiliary group is cleaved to provide the pure desired enantiomer. Alternatively, when the molecule contains a basic functional group (e.g., amino) or an acidic functional group (e.g., carboxyl), a diastereomeric salt is formed with an appropriate optically active acid or base, and then the diastereomers are resolved by conventional methods known in the art and recovered to obtain the pure enantiomer. Also, the separation of enantiomers and diastereomers is usually carried out using chromatography with a chiral stationary phase and optionally in combination with a chemical derivatization method (e.g., generating a carbamate from an amine).

[0089] The compounds of the present invention may contain an unnatural proportion of atomic isotopes in one or more of the atoms that make up the compound. For example, the compound can be labeled with radioactive isotopes such as tritium ( 3 H), iodine-125 ( 125 I), C-14 ( 14 C), etc. Or for example, hydrogen can be replaced with deuterium to form a deuterated drug, and the bond formed between deuterium and carbon is stronger than the bond formed between normal hydrogen and carbon. Compared with the non-deuterated drug, the deuterated drug has advantages such as reducing toxic side effects, enhancing drug stability, enhancing efficacy, and extending the biological half-life of the drug. The conversion of the isotope composition of the compounds of the present invention is included within the scope of the present invention regardless of whether it is radioactive or not.

[0090] The terms "optionally" or "optionally with" refer to the fact that the matters or situations described thereafter may occur but do not necessarily have to occur, and the description includes both the cases where the matters or situations occur and the cases where the matters or situations do not occur.

[0091] The term "substituted" means that any one or more hydrogen atoms at a particular atom are substituted with a substituent, and the substituent may include deuterium and variants of hydrogen as long as the valence of the particular atom is normal and the substituted compound is stable. When the substituent is a keto group (i.e., =O), it means that two hydrogen atoms are substituted. Keto group substitution does not occur in aromatic groups. The term "optionally substituted" means that it may or may not be substituted, and unless otherwise specified, the type and number of substituents are arbitrary as long as they are chemically feasible.

[0092] If any of the variables (e.g., R) appears one or more times in the composition or structure of the compound, its definition is independent in each case. Therefore, for example, when one group is substituted with 0 to 2 Rs, the above group is optionally substituted with 2 or fewer Rs, and in each case, R has independent options. Also, combinations of substituents and / or their variants are only permitted if such combinations result in a stable compound.

[0093] When the number of linking groups is 0, for example, -(CRR)0- means that the linking group is a single bond. When the substituent is empty, it means that the substituent does not exist. For example, when X in A-X is empty, the structure actually means A. When it is not indicated through which atom the listed substituent is bonded to the substituted group, such a substituent can be bonded through any of its atoms. For example, pyridinyl as a substituent may be bonded to the substituted group through any carbon atom of the pyridine ring.

[0094] Unless otherwise specified, when a group has one or more bondable sites, any one or more sites of the group can be bonded to other groups by chemical bonds. When the bonding mode of the chemical bond is delocalized and there is an H atom at the bondable site, when bonding with the chemical bond, the number of H atoms at the site decreases to a group with a corresponding valence according to the number of the bonded chemical bonds. The chemical bond by which the site is bonded to another group is a straight solid line bond (
