Definition and description
The following terms and phrases used herein are intended to have the following meanings unless otherwise indicated. A particular term or phrase, unless otherwise specifically defined, should not be construed as being ambiguous or otherwise clear, but rather should be construed in a generic sense. When trade names are presented herein, it is intended to refer to their corresponding commercial products or active ingredients thereof.
The term "pharmaceutically acceptable" as used herein refers to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.
The term "pharmaceutically acceptable salts" refers to salts of the compounds of the present application prepared from the compounds found herein to have a particular substituent with a relatively non-toxic acid or base. When relatively acidic functionalities are included in the compounds of the present application, base addition salts may be obtained by contacting such compounds with a sufficient amount of base in pure solution or in a suitable inert solvent. When the compounds of the present invention contain relatively basic functional groups, the acid addition salts may be obtained by contacting such compounds with a sufficient amount of acid in pure solution or in a suitable inert solvent. Certain specific compounds of the invention contain basic and acidic functionalities that can be converted to either base or acid addition salts.
Pharmaceutically acceptable salts of the invention can be synthesized from the parent compound containing an acid or base by conventional chemical methods. In general, the preparation of such salts is as follows: prepared via reaction of these compounds in free acid or base form with a stoichiometric amount of the appropriate base or acid in water or an organic solvent or a mixture of both.
Unless otherwise indicated, the term "isomer" is intended to include geometric isomers, cis-trans isomers, stereoisomers, enantiomers, optical isomers, diastereomers and tautomers.
The compounds of the invention may exist in specific geometric or stereoisomeric forms. The present invention contemplates all such compounds, including cis and trans isomers, (-) -and (+) -enantiomers, (R) -and (S) -enantiomers, diastereomers, (D) -isomers, (L) -isomers, and racemic mixtures and other mixtures thereof, such as enantiomerically or diastereomerically enriched mixtures, all of which are within the scope of the invention. Additional asymmetric carbon atoms may be present in substituents such as alkyl groups. All such isomers and mixtures thereof are included within the scope of the present invention.
Unless otherwise indicated, the term "enantiomer" or "optical isomer" refers to stereoisomers that are mirror images of each other.
Unless otherwise indicated, the term "cis-trans isomer" or "geometric isomer" is caused by the inability of a double bond or a single bond of a ring-forming carbon atom to rotate freely.
Unless otherwise indicated, the term "diastereoisomer" refers to stereoisomers of a molecule having two or more chiral centers and having a non-mirror relationship between the molecules.
Unless otherwise indicated, "(+)" means dextrorotation, "(-)" means levorotatory, "(±)" means racemization.
Unless otherwise indicated, with solid wedge bondsAnd a wedge-shaped dotted bondRepresenting the absolute configuration of a solid centre by straight solid keysAnd straight dotted line keyRepresenting the relative configuration of the stereogenic centers, e.g.Indicating that Rx and Ry are co-directional and comprisingTwo configurations.
Unless otherwise specified, when a group has one or more bondable sites, any one or more of the sites of the group may be bonded to other groups by chemical bonds. When the connection mode of the chemical bond is not positioned and the H atoms exist in the connectable site, the number of the H atoms of the site can be correspondingly reduced to be changed into the corresponding valence group along with the number of the connected chemical bond when the chemical bond is connected. The chemical bond of the site and other groups can be a straight solid line bondStraight dotted line keyOr wave linesAnd (3) representing. For example, a straight solid bond in-OCH 3 indicates that it is attached to other groups through an oxygen atom in that group;the straight dashed bonds in (a) represent the attachment to other groups through both ends of the nitrogen atom in the group; by straight broken double bonds Representing the linkage between groups by double bonds, e.g.The double bond of the straight-line indicates that the cyclohexyl group is doubly bonded to other groups.
The compounds of the invention may be present in particular. Unless otherwise indicated, the term "tautomer" or "tautomeric form" refers to the fact that at room temperature, different functional group isomers are in dynamic equilibrium and are capable of rapid interconversion. If tautomers are possible (e.g., in solution), chemical equilibrium of the tautomers can be reached. For example, proton tautomers (also known as proton tautomers) (prototropic tautomer) include interconversions by proton transfer, such as keto-enol isomerisation and imine-enamine isomerisation. Valence isomer (valance tautomer) includes the interconversion by recombination of some of the bond-forming electrons. A specific example of where keto-enol tautomerization is the interconversion between two tautomers of pentane-2, 4-dione and 4-hydroxypent-3-en-2-one.
Unless otherwise indicated, the terms "enriched in one isomer", "enriched in one enantiomer" or "enantiomerically enriched" mean that the content of one isomer or enantiomer is less than 100% and the content of the isomer or enantiomer is greater than or equal to 60%, or greater than or equal to 70%, or greater than or equal to 80%, or greater than or equal to 90%, or greater than or equal to 95%, or greater than or equal to 96%, or greater than or equal to 97%, or greater than or equal to 98%, or greater than or equal to 99%, or greater than or equal to 99.5%, or greater than or equal to 99.6%, or greater than or equal to 99.7%, or greater than or equal to 99.8%, or greater than or equal to 99.9%.
Unless otherwise indicated, the term "isomer excess" or "enantiomeric excess" refers to the difference between the relative percentages of two isomers or enantiomers. For example, where one isomer or enantiomer is present in an amount of 90% and the other isomer or enantiomer is present in an amount of 10%, the isomer or enantiomer excess (ee value) is 80%.
Optically active (R) -and (S) -isomers and D and L isomers can be prepared by chiral synthesis or chiral reagents or other conventional techniques. If one enantiomer of a compound of the invention is desired, it may be prepared by asymmetric synthesis or derivatization with chiral auxiliary wherein the resulting diastereomeric mixture is separated and the auxiliary group 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 diastereomeric resolution is carried out by conventional methods well known in the art, and then the pure enantiomer is recovered. Furthermore, the separation of enantiomers and diastereomers is usually accomplished by using chromatography employing a chiral stationary phase, optionally in combination with chemical derivatization), for example, to form carbamates from amines.
The compounds of the present invention may contain non-natural proportions of atomic isotopes on one or more of the atoms comprising the compounds.
