Definitions
- the invention relates to the preparation of 3-position heterocyclic substituted piperidine-2,6-diones of the general formula I.
- heterocyclic substituted piperidine-2,6-diones their preparation and use in medicaments, especially as immunomodulators for the treatment and / or prophylaxis of inflammatory and autoimmune diseases and haematological-oncological diseases are known from WO 03/053956 A1.
- the problem underlying the invention was therefore to develop a process for the preparation of said compounds, which can be carried out with as few synthesis steps as possible.
- the invention accordingly provides a process for preparing piperidine-2,6-diones of general formula I which are heterocyclically substituted in the 3-position,
- R 1 and R 2 the same or different from each other, H, Br, Cl, F, CF 3 , OH, NO 2 , NH 2 , N (CH 3 ) 2 , C 1-3 alkyl, C 1-3 Alkoxy, phenyl or, taken together, denote a fused-on benzene ring, the rings being optionally substituted by R 1 and / or R 2 and R 1 and R 2 being as defined above,
- R 3 is as defined above and X represents the anion of a suitable acid, preferably acetic acid, then compounds of general formula I are obtained with the corresponding meaning of R 3 .
- R 6 represents Cl, the imidazol-1-yl radical, a C 1 -C 4 -alkoxy, a phenyloxy or a nitro group, chlorine or fluorine-substituted phenyloxy group or a thiomethyl group, or by reaction of (IV) with C 1 -C 4 -alkyl, phenyl or substituted phenyl esters, preferably 4-nitro, 4-chloro- or 4-fluorophenyl esters, of chloroformic acid.
- R 7 is the methyl or ethyl radical.
- the reaction of the aminobenzylamines of the general formula (II) with the 3-bromoglutarimides of the general formula (III) is preferably carried out in inert solvents, preferably tetrahydrofuran or 1,4-dioxane, in the presence of tertiary amines, preferably triethylamine. or ethyl diisopropylamine at elevated temperature or in dimethylformamide as solvent at temperatures between 0 and 100 ° C, preferably 20 ° C.
- the inventive method allows in comparison to the known from WO 03/053956 A1 production process with six stages and subsequent base release and hydrochloride precipitation a very advantageous reduction of the synthesis steps by half.
- the compounds according to the invention can be prepared as pure enantiomers or nonracemic mixtures of enantiomers, racemates,
- Diastereomers or Diastereomerengemische both in the form of their free bases and salts with physiologically acceptable organic or inorganic acids. They possess immunomodulatory activity, that is, they induce a drastic reduction of IL-12 production in LPS-activated monocytes with concomitant increase in IL-10 production. Because of this principle of action, these compounds have a great therapeutic Potential in diseases where excessive IL-12 production and relative lack of IL-10 are implicated in the pathogenesis, that is, such compounds are to be used for the treatment and / or prophylaxis of inflammatory and autoimmune diseases. Due to the anti-apoptotic effect of IL-12, the compounds obtained according to the invention are also suitable for suppressing the formation of IL-12 in haematological-oncological diseases.
- Diseases of the above-mentioned types include inflammation of the skin (eg atopic dermatitis, psoriasis, eczema, erythema nodosum leprosum), respiratory tract inflammation (eg bronchitis, pneumonia, bronchial asthma, adult respiratory distress syndrome (ARDS), sarcoidosis, silicosis / Fibrosis), inflammation of the gastrointestinal tract (eg gastroduodenal ulcers, Crohn's disease, ulcerative colitis), as well as diseases such as hepatitis, pancreatitis, appendicitis, peritonitis, nephritis, aphthosis, conjunctivitis, keratitis, uveitis, rhinitis.
- inflammation of the skin eg atopic dermatitis, psoriasis, eczema, erythema nodosum leprosum
- respiratory tract inflammation eg
- the autoimmune diseases include e.g. Arthritic disorders (e.g., rheumatoid arthritis, HLA-B27 associated diseases, rheumatoid spondylitis), multiple sclerosis, juvenile diabetes or lupus erythematosus.
- Other indications include sepsis, septic shock, bacterial meningitis, mycobacterial infections, opportunistic infections in AIDS, cachexia, transplant rejection, graft-versus-host reactions, and chronic heart failure, congestive heart failure, the reperfusion syndrome, and atherosclerosis.
- fibromyalgia fibromyalgia
- Sudeck's disease reflex sympathetic dystrophy (RSD)
- haematological disorders such as multiple myeloma, myelodisplastic syndrome and leukemia, as well as other oncological diseases Diseases such as glioblastoma, prostate, renal cell, mammary, thyroid, head and neck, pancreatic and colorectal carcinoma as well as melanoma and Kaposi's sarcoma to the clinical pictures in which the immunomodulators according to the invention are to be used.
- the stationary phase used for the chromatographic separations was silica gel 60 (0.040 to 0.063 mm) from E. Merck, Darmstadt.
- the mixing ratios of the eluents are always given in volume / volume.
- the substances were characterized by their melting point and / or NMR spectra. The spectra were recorded at 300 MHz using the Gemini 300 device from Varian. The chemical shifts are given in ppm ( ⁇ scale).
