The present invention also includes pharmaceutically acceptable salts of the compounds described herein. As used herein, “pharmaceutically acceptable salts” refers to derivatives of the disclosed compounds wherein the parent compound is modified by converting an existing acid or base moiety to its salt form. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts of the present invention include the conventional non-toxic salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418 and Journal of Pharmaceutical Science 1977, 66 (2), each of which is incorporated herein by reference in its entirety.
The phrase “pharmaceutically acceptable” is employed herein 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.
Furthermore, in the case of the compounds of the invention which contain an asymmetric carbon atom or an atropoisomeric bond, the invention relates to the D form, the L form and D,L mixtures and also, where more than one asymmetric carbon atom or atropoisomeric bond is present, to the diastereomeric forms. Those compounds of the invention which contain asymmetric carbon atoms or atropoisomeric bonds, and which as a rule accrue as racemates, can be separated into the optically active isomers in a known manner, for example using an optically active acid. However, it is also possible to use an optically active starting substance from the outset, with a corresponding optically active or diastereomeric compound then being obtained as the end product.
Compounds of the invention also include tautomeric forms. Tautomeric forms result from the swapping of a single bond with an adjacent double bond together with the concomitant migration of a proton. Tautomeric forms include prototropic tautomers which are isomeric protonation states having the same empirical formula and total charge. Example prototropic tautomers include ketone-enol pairs, amide-imidic acid pairs, lactam-lactim pairs, amide-imidic acid pairs, enamine-imine pairs, and annular forms where a proton can occupy two or more positions of a heterocyclic system, for example, 1H- and 3H-imidazole, 1H-, 2H- and 4H-1,2,4-triazole, 1H- and 2H-isoindole, and 1H- and 2H-pyrazole. Tautomeric forms can be in equilibrium or sterically locked into one form by appropriate substitution.
The compounds described herein can be asymmetric (e.g., having one or more stereocenters). All stereoisomers, such as enantiomers and diastereomers, are intended unless otherwise indicated. Compounds of the present invention that contain asymmetrically substituted carbon atoms can be isolated in optically active or racemic forms. Methods on how to prepare optically active forms from optically active starting materials are known in the art, such as by resolution of racemic mixtures or by stereoselective synthesis. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms.
Compounds of the invention can also include all isotopes of atoms occurring in the intermediates or final compounds. Isotopes include those atoms having the same atomic number but different mass numbers. For example, isotopes of hydrogen include tritium and deuterium.
Also included are solvates and hydrates of the compounds of the invention and solvates and hydrates of their pharmaceutically acceptable salts.
The term “compound” as used herein is meant to include all stereoisomers, geometric isomers, tautomers, rotamers, and isotopes of the structures depicted, unless otherwise indicated.
In some embodiments, the compound can be provided as a prodrug. The term “prodrug”, as employed herein, denotes a compound, which, upon administration to a subject, undergoes chemical conversion by metabolic or chemical processes to yield a compound of the invention, or a salt and/or solvate thereof.
In some embodiments, the compounds of the invention, and salts thereof, are substantially isolated. By “substantially isolated” is meant that the compound is at least partially or substantially separated from the environment in which it was formed or detected. Partial separation can include, for example, a composition enriched in the compound of the invention. Substantial separation can include compositions containing at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 97%, or at least about 99% by weight of the compound of the invention, or salt thereof.
Pharmaceutical Methods
The compounds according to the invention have been found to have pharmacologically important properties, which can be used therapeutically. The compounds of the invention can be used alone, in combination with each other or in combination with other active compounds.
In certain embodiments, compounds of the present invention may exhibit growth inhibiting properties in hyperproliferative processes.
The antiproliferative activities of compounds falling under formula (Ia), (Ib) and (Ic), respectively, were investigated on cells or cell lines originating from a disorder of the haematopoietic system, including the myeloid cell compartment and the lymphoid cell compartment (T-cells and B-cells), the neuroendocrine system, the cervix, the breast, the ovaries, the lung, the gastrointestinal tract, and the mucosal epithelium, as well as from the skin epithelium and from the muscle. To this end, HL-60 cells, NB-4 cells, HH cells, RPMI-8402 cells, TANOUE cells, TT cells, HeLa cells, MDA-MB-231 cells, FU-OV-1 cells, LOU-NH91 cells, 23132/87 cells, CAL-27 cells, BHY cells, SCC-25 cells, A-431 cells, human primary epidermal keratinocytes (HPEK), and C2C12 cells were seeded into 96-well plates suitable for fluorescence assays (CORNING #3598) at following initial cell numbers: 1000 cells per well for HL-60; 1000 cells per well for NB-4; 5000 cells per well for HH; 5000 cells per well for RPMI-8402; 1500 cells per well for TANOUE; 9000 cells per well for TT; 2000 cells per well for HeLa; 3000 cells per well for MDA-MB-231; 3000 cells per well for FU-OV-1; 4000 cells per well for LOU-NH91; 2000 cells per well for 23132/87; 2000 cells per well for CAL-27; 1500 cells per well for BHY; 1500 cells per well for SCC-25; 700 cells per well for A-431; 1000 cells per well for HPEK; 500 cells per well for C2C12. The cells were treated with compounds at indicated final concentrations (diluted from the 1000× stock-solutions in DMSO to a final DMSO concentration of 0.1% v/v in H2O (Water For Injection, WFI, Fisherscientific #10378939)) or with the empty carrier DMSO at 0.1% v/v as control for 5 days. At day 5 after starting the treatments the cells were subjected to the alamarBlue® Proliferation Assay (Bio-Rad Serotec GmbH, BUF012B) according to the protocol of the manufacturer. The readout was taken with a multi-well plate-reader in the fluorescence mode with applying a filter for excitation at 560 nm (band width 10 nm) and for emission at 590 nm (band width 10 nm). Control treatments for growth inhibition with commercial compounds such as Methotrexate (MTREX) and Resveratrol (RES) were included on every plate.
The assays were performed in duplicate or more replicates of independent single experiments each containing a six-fold replicate for every condition. For every individual plate, the measured fluorescence intensity values of the conditions with compound treatment were normalized against the corresponding equally weighted arithmetic mean of the fluorescence intensity values of the six DMSO treated control wells in order to obtain the relative values to a baseline level of 1.0.
Two independent outlier analyses were performed according to the methods by Peirce and Chauvenet (Ross, Journal of Engineering Technology 2003, 1-12). Outliers confirmed by at least one of the methods were excluded from the calculations but not more than one value out of six per compound within a single experiment. The weighted arithmetic mean (here abbreviated as AVEw) for each compound was calculated from the normalized values over all independent replicates of the single experiments comprising the six replicates each. The corresponding standard deviation for the weighted arithmetic mean was calculated according to the method described by Bronstein et al. (Bronstein, Semendjajew, Musiol, Miihlig, Taschenbuch der Mathematik, 5th edition 2001 (German), publisher: Verlag Harri Deutsch, Frankfurt am Main and Thun) and was combined with the Gauß′ error propagation associated with the performed calculation for the normalization. The resulting standard deviation is herein referred to as “combined standard deviation”.
In cases with considerable variation in the normalized equally weighted arithmetic means derived from two independent replicates, the number of independent replicates was increased to three or more. In the cases of four or more independent replicates, a second-line outlier analysis was applied on all normalized equally weighted arithmetic means according to the methods by Peirce and Chauvenet as described above.
