the term "pharmaceutically acceptable" as used herein is intended to refer 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 invention, prepared from the compounds of the present invention found to have particular substituents, with relatively nontoxic acids or bases. When compounds of the present invention contain relatively acidic functional groups, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of a base in neat solution or in a suitable inert solvent. Pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic ammonia or magnesium salts or similar salts. When compounds of the present invention contain relatively basic functional groups, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of acid in neat solution or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include inorganic acid salts including, for example, hydrochloric acid, hydrobromic acid, nitric acid, carbonic acid, bicarbonate, phosphoric acid, monohydrogen phosphate, dihydrogen phosphate, sulfuric acid, hydrogen sulfate, hydroiodic acid, phosphorous acid, and the like; and salts of organic acids including acids such as acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-toluenesulfonic, citric, tartaric, methanesulfonic, and the like; also included are Salts of amino acids (e.g., arginine, etc.), and Salts of organic acids such as glucuronic acid (see Berge et al, "Pharmaceutical Salts," Journal of Pharmaceutical Science 66:1-19 (1977)). Certain specific compounds of the invention contain both basic and acidic functionalities and can thus be converted to any base or acid addition salt.
Preferably, the neutral form of the compound is regenerated by contacting the salt with a base or acid and isolating the parent compound in a conventional manner. The parent form of the compound differs from the various salt forms by certain physical properties, such as solubility in polar solvents.
As used herein, "pharmaceutically acceptable salts" belong to derivatives of the compounds of the present invention, wherein the parent compound is modified by forming a salt with an acid or a salt with a base. Examples of pharmaceutically acceptable salts include, but are not limited to: inorganic or organic acid salts of bases such as amines, alkali metal or organic salts of acid groups such as carboxylic acids, and the like. Pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound, for example, salts formed with non-toxic inorganic or organic acids. Conventional non-toxic salts include, but are not limited to, those derived from inorganic or organic acids selected from the group consisting of 2-acetoxybenzoic acid, 2-hydroxyethanesulfonic acid, acetic acid, ascorbic acid, benzenesulfonic acid, benzoic acid, bicarbonate, carbonic acid, citric acid, edetic acid, ethanedisulfonic acid, ethanesulfonic acid, fumaric acid, glucoheptose, gluconic acid, glutamic acid, glycolic acid, hydrobromic acid, hydrochloric acid, hydroiodide, hydroxyl, hydroxynaphthalene, isethionic acid, lactic acid, lactose, dodecylsulfonic acid, maleic acid, malic acid, mandelic acid, methanesulfonic acid, nitric acid, oxalic acid, pamoic acid, pantothenic acid, phenylacetic acid, phosphoric acid, polygalacturonic acid, propionic acid, salicylic acid, stearic acid, glycolic acid, succinic acid, sulfamic acid, sulfanilic acid, sulfuric acid, tannin, tartaric acid, and p-toluenesulfonic acid.
The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound, which contains an acid or base, by conventional chemical methods. In general, such salts are prepared by the following method: prepared by reacting 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 the two. Generally, nonaqueous media such as ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred.
In addition to salt forms, the compounds provided herein also exist in prodrug forms. Prodrugs of the compounds described herein readily undergo chemical changes under physiological conditions to convert to the compounds of the present invention. In addition, prodrugs can be converted to the compounds of the present invention in an in vivo environment by chemical or biochemical means.
Certain compounds of the present invention may exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms are equivalent to unsolvated forms and are intended to be encompassed within the scope of the present invention. Certain compounds of the present invention may exist in polycrystalline or amorphous form.
Certain compounds of the present invention may have asymmetric carbon atoms (optical centers) or double bonds. Racemates, diastereomers, geometric isomers and individual isomers are all included within the scope of the present invention.
The illustrations of enantiomers, ambiscalemic and scalemic or enantiomerically pure compounds herein are from Maehr, J.chem.Ed.1985,62: 114-120. In 1985,62: 114-120. Unless otherwise indicated, the absolute configuration of a stereocenter is indicated by wedge bonds and dashed bonds. When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, they include the E, Z geometric isomer unless otherwise specified. Likewise, all tautomeric forms are included within the scope of the invention.
The compounds of the present 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, as well as racemic and other mixtures thereof, such as enantiomerically or diastereomerically enriched mixtures, all of which are within the scope of the present invention. Additional asymmetric carbon atoms may be present in substituents such as alkyl groups. All such isomers, as well as mixtures thereof, are included within the scope of the present invention.
Optically active (R) -and (S) -isomers as well as D and L isomers can be prepared by chiral synthesis or chiral reagents or other conventional techniques. If one of the enantiomers of a compound of the invention is desired, it can be prepared by asymmetric synthesis or derivatization with a chiral auxiliary, wherein the resulting diastereomeric mixture 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), diastereomeric salts are formed with an appropriate optically active acid or base, followed by resolution of the diastereomers by fractional crystallization or chromatography, as is well known in the art, and the pure enantiomers are recovered. Furthermore, separation of enantiomers and diastereomers is typically accomplished by using chromatography employing a chiral stationary phase, optionally in combination with chemical derivatization (e.g., carbamate formation from amines).
The compounds of the present invention may contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds may be labelled with radioactive isotopes, such as tritium (A), (B), (C3H) Iodine-125 (125I) Or C-14(14C) In that respect All isotopic variations of the compounds of the present invention, whether radioactive or not, are intended to be encompassed within the scope of the present invention.
The term "pharmaceutically acceptable carrier" refers to any formulation or carrier medium capable of delivering an effective amount of an active agent of the present invention, without interfering with the biological activity of the active agent, and without toxic side effects to the host or patient, and representative carriers include water, oils, vegetables and minerals, cream bases, lotion bases, ointment bases, and the like. These include suspending agents, viscosity enhancers, skin penetration enhancers, and the like. Their preparation is known to those skilled in the cosmetic or topical pharmaceutical field. For additional information on The vector, reference may be made to Remington, The Science and Practice of Pharmacy,21st Ed., Lippincott, Williams & Wilkins (2005), The contents of which are incorporated herein by reference.
The term "excipient" generally refers to a carrier, diluent, and/or vehicle necessary to formulate an effective pharmaceutical composition.
The term "effective amount" or "therapeutically effective amount" with respect to a drug or pharmacologically active agent refers to a sufficient amount of the drug or agent that is non-toxic but achieves the desired effect. For oral dosage forms of the invention, an "effective amount" of one active agent in a composition is the amount required to achieve the desired effect when combined with another active agent in the composition. The determination of an effective amount varies from person to person, depending on the age and general condition of the recipient and also on the particular active substance, and an appropriate effective amount in an individual case can be determined by a person skilled in the art according to routine tests.
The terms "active ingredient," "therapeutic agent," "active substance," or "active agent" refer to a chemical entity that is effective in treating a target disorder, disease, or condition.
The term "substituted" means that any one or more hydrogen atoms on a particular atom is replaced with a substituent, including deuterium and hydrogen variants, so long as the valency 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. The keto substitution does not occur on the aromatic group. The term "optionally substituted" means that it may or may not be substituted, and unless otherwise specified, the kind and number of substituents may be arbitrary on the basis of chemical realizability.
When any variable (e.g., R) occurs more than one time in the composition or structure of a compound, its definition in each case is independent. Thus, for example, if a group is substituted with 0-2R, the group may optionally be substituted with up to two R, and there are separate options for R in each case. Furthermore, combinations of substituents and/or variants thereof are permissible only if such combinations result in stable compounds.
When a substituent's bond can cross-link two atoms on a ring, such substituent can be bonded to any atom on the ring. When no atom is indicated in the listed substituents for connecting to a compound included in the general chemical structure but not specifically mentioned, such substituent may be bonded through any atom thereof. Combinations of substituents and/or variants thereof are permissible only if such combinations result in stable compounds.
