Description
Technical Field
The invention relates to a steroid compound and application thereof in preparing a medicament for treating ophthalmic diseases.
Background
Cataracts belong to the disease of the eye, occurring on the crystalline lens within the eyeball, and opacification of the crystalline lens is collectively called cataract. Aging, genetic, metabolic abnormalities, trauma, radiation, poisoning, localized dystrophy, etc. can cause damage to the lens capsule, increase its permeability, lose barrier function, or cause metabolic disturbance of the lens, denature lens proteins, and create opacity. If the lens of the eye changes from transparent to opaque, which affects the ability of the eye to receive sunlight, the vision of the eye is affected. The eyeball turbidity is light, the influence on the vision is light, the vision is increased along with the gradual deepening of the turbidity, and the serious patient can cause blindness. Cataract is one of the most common blinding eye diseases, and is a major factor causing blindness. Because the mechanism of cataract formation is not clear, the drug therapy has not made breakthrough progress so far. Therefore, the only treatment identified to be effective at present is surgical treatment.
Although the continuous progress of the cataract surgery mode provides great help for the treatment of cataract, the cure rate of the surgery treatment is still far lower than the incidence rate, and the possibility of serious complications exists; on the other hand, surgical treatment of cataract is very costly, and even in developed countries, cataract imposes a great burden on the medical insurance system. Therefore, the prevention and treatment of the medicament plays a role in promoting weight. Currently, the clinical treatments for cataracts include: aldose reductase inhibitors such as cataline (cataline, carinoyl, albuterol), phacolin, bendazac lysine, etc.; anti-oxidative damage drugs such as glutathione, taurine, aspirin, and the like; nutritional and metabolic drugs such as vitamins and carotenoids; the Chinese medicinal composition comprises herba Dendrobii herba noctilus pill, QIJUDIHUANG pill, and Concha Haliotidis powder. The long-term clinical tests prove that the medicines for treating the cataract can only delay the deterioration of the cataract and can not reverse the condition of the cataract. Meanwhile, as China begins to step into an aging society, the number of cataract patients is increasing, and the demand of cataract drugs is more urgent.
Therefore, there is a great clinical need for new ophthalmic external anti-cataract drugs that are safe, have good efficacy, have strong intraocular penetration and are stable in properties.

Reference will now be made in detail to certain embodiments of the invention, examples of which are illustrated by the accompanying structural and chemical formulas. The invention is intended to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims. One skilled in the art will recognize that many methods and materials similar or equivalent to those described herein can be used in the practice of the present invention. The present invention is in no way limited to the methods and materials described herein. In the event that one or more of the incorporated documents, patents, and similar materials differ or contradict this application (including but not limited to defined terminology, application of terminology, described techniques, and the like), this application controls.
It will be further appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. All patents and publications referred to herein are incorporated by reference in their entirety.
The following definitions as used herein should be applied unless otherwise indicated. For the purposes of the present invention, the chemical elements are in accordance with the CAS version of the periodic Table of the elements, and the handbook of chemistry and Physics, 75 th edition, 1994. In addition, general principles of Organic Chemistry can be found in the descriptions of "Organic Chemistry", thomas Sorrell, university Science Books, sausaltio: 1999, and "March's Advanced Organic Chemistry" by Michael B.Smith and Jerry March, john Wiley & Sons, new York:2007, the entire contents of which are incorporated herein by reference.
The articles "a," "an," and "the" as used herein are intended to include "at least one" or "one or more" unless otherwise indicated or clearly contradicted by context. Thus, the articles are used herein to refer to articles of one or more than one (i.e., to at least one) object. For example, "a component" refers to one or more components, i.e., there may be more than one component contemplated for use or use in embodiments of the described embodiments.
The term "subject" as used herein refers to an animal. Typically the animal is a mammal. Subjects, e.g., also primates (e.g., humans, male or female), cows, sheep, goats, horses, dogs, cats, rabbits, rats, mice, fish, birds and the like. In certain embodiments, the subject is a primate. In other embodiments, the subject is a human.
The term "patient" as used herein refers to humans (including adults and children) or other animals. In some embodiments, "patient" refers to a human.
The term "comprising" is open-ended, i.e. including what is specified in the invention, but not excluding other aspects.
"stereoisomers" refers to compounds having the same chemical structure, but differing in the arrangement of atoms or groups in space. Stereoisomers include enantiomers, diastereomers, conformers (rotamers), geometric isomers (cis/trans), atropisomers, and the like.
"diastereomer" refers to a stereoisomer having two or more chiral centers and whose molecules are not mirror images of each other. Diastereomers have different physical properties, such as melting points, boiling points, spectral properties, and reactivities. Mixtures of diastereomers may be separated by high resolution analytical procedures such as electrophoresis and chromatography, e.g., HPLC.
The stereochemical definitions and rules used in the present invention generally follow the general definitions of S.P. Parker, ed., mcGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, new York; and Eliel, E.and Wilen, S., "Stereochemistry of organic Compounds", john Wiley & Sons, inc., new York,1994.
Many organic compounds exist in an optically active form, i.e., they have the ability to rotate the plane of plane polarized light. In describing optically active compounds, the prefixes D and L or R and S are used to denote the absolute configuration of a molecule with respect to one or more of its chiral centers. The prefixes d and l or (+) and (-) are the symbols used to specify the rotation of plane polarized light by the compound, where (-) or l indicates that the compound is left-handed. Compounds prefixed with (+) or d are dextrorotatory. A particular stereoisomer is an enantiomer and a mixture of such isomers is referred to as an enantiomeric mixture. A 50.
Any asymmetric atom (e.g., carbon, etc.) of a compound disclosed herein can exist in racemic or enantiomerically enriched forms, such as the (R) -, (S) -or (R, S) -configuration. In certain embodiments, each asymmetric atom has at least 50% enantiomeric excess, at least 60% enantiomeric excess, at least 70% enantiomeric excess, at least 80% enantiomeric excess, at least 90% enantiomeric excess, at least 95% enantiomeric excess, or at least 99% enantiomeric excess in the (R) -or (S) -configuration.
Depending on the choice of starting materials and methods, the compounds according to the invention may be present in the form of one of the possible isomers or of mixtures thereof, for example racemates and diastereoisomeric mixtures (depending on the number of asymmetric carbon atoms). The optically active (R) -or (S) -isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituents may be in the E or Z configuration; if the compound contains a disubstituted cycloalkyl group, the substituents of the cycloalkyl group may have cis or trans configuration.
Any resulting mixture of stereoisomers may be separated into pure or substantially pure geometric isomers, enantiomers, diastereomers, depending on differences in the physicochemical properties of the components, for example, by chromatography and/or fractional crystallization.
Unless otherwise indicated, the structural formulae depicted herein include all isomeric forms (e.g., enantiomers, diastereomers, and geometric isomers (or conformers): e.g., (Z), (E) isomers of double bonds, and (Z), (E) conformers of R, S configurations containing asymmetric centers.
The term "prodrug", as used herein, represents a compound that is converted in vivo to a compound of formula (I). Such conversion is effected by hydrolysis of the prodrug in the blood or by enzymatic conversion to the parent structure in the blood or tissue. The prodrug compounds of the invention can be esters, and in the prior invention, the esters can be used as prodrugs such as benzene esters, aliphatic (C1-24) esters, acyloxymethyl esters, carbonates, carbamates and amino acid esters. For example, a compound of the present invention contains a hydroxy group, i.e., it can be acylated to provide the compound in prodrug form. Other prodrug forms include phosphate esters, such as those obtained by phosphorylation of a hydroxyl group on the parent. For a complete discussion of prodrugs, reference may be made to the following: t.higuchi and v.stella, pro-drugs as Novel Delivery Systems, vol.14 of the a.c.s.symposium Series, edward b.roche, ed., bioreversible Carriers in Drug Design, american Pharmaceutical Association and Pergamon Press,1987, j.rautio et al, produgs: design and Clinical Applications, nature Review Drug Discovery,2008,7,255-270, and S.J. Hecker et al, prodrugs of Phosphonates and Phosphonates, journal of medical chemistry,2008,51, 2328-2345.
The racemates of any resulting final products or intermediates can be resolved into the optical enantiomers by known methods, by methods familiar to those skilled in the art, e.g., by separation of the diastereomeric salts obtained. The racemic product can also be separated by chiral chromatography, e.g., high Performance Liquid Chromatography (HPLC) using a chiral adsorbent. In particular, enantiomers can be prepared by asymmetric synthesis, for example, see Jacques, et al, enantiomers, racemates and solutions (Wiley Interscience, new York, 1981); principles of Asymmetric Synthesis (2nd Ed. Robert E. Gawley, jeffrey Aub, elsevier, oxford, UK, 2012); eliel, E.L. Stereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); wilen, S.H.tables of solving Agents and Optical solutions p.268 (E.L.Eliel, ed., univ.of Notre Dame Press, notre Dame, IN 1972); chiral Separation Techniques: A Practical Approach (Subramanian, G.Ed., wiley-VCH Verlag GmbH & Co. KGaA, weinheim, germany, 2007).
The term "tautomer" or "tautomeric form" refers to structural isomers having different energies that can be interconverted by a low energy barrier (low energy barrier). If tautomerism is possible (e.g., in solution), then the chemical equilibrium of the tautomer can be reached. For example, proton tautomers (also known as proton transfer tautomers) include interconversions by proton migration, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers (value tautomers) include interconversion by recombination of some of the bonding electrons. A specific example of keto-enol tautomerism is the tautomerism of the pentan-2, 4-dione and 4-hydroxypent-3-en-2-one tautomers. Another example of tautomerism is phenol-ketone tautomerism. One specific example of phenol-ketone tautomerism is the tautomerism of pyridin-4-ol and pyridin-4 (1H) -one tautomers. Unless otherwise indicated, all tautomeric forms of the compounds of the invention are within the scope of the invention.
