Definitions
- Bone marrow edema is associated
- the invention relates to the subject-matter set out in the patent claims, that is to say the use of orally available prostacyclin derivatives for the production of a medicament for the treatment of diseases which are associated with bone marrow edema.
- Osteonecrosis (syn .: aseptic necrosis, avascular necrosis, ischemic necrosis) is a common disease. Pain is the main symptom. In about two thirds of the patients, this pain occurs at rest. Osteonecrosis is often described as a transient process. In the spontaneous course, there is usually a complete healing after 6 to 12 months. During this period, however, the patient is exposed to severe pain, which is often not even accessible to conventional pain therapy. The incidence rates of the progression of early osteonecrosis to the end stage with pronounced bone necrosis are not known. Osteonecrosis is responsible for more than 10% of all joint replacement surgery performed annually.
- Knee osteoarthritis is a common disease that affects approximately 11-15% of people over 65 and is the most common cause of physical illness
- Osteoarthritis is defined as primarily non-inflammatory joint destruction, which begins with cartilage dying in adults and later also affects the other joint structures and progresses irreversibly. The overall course is usually progressive, but changes in phases with regard to clinical acuity. In the final stage, knee replacement is necessary.
- osteonecrosis and osteoarthritis on the hip and knee joints, but also on the shoulder, wrist and ankle. While in the treatment of osteonecrosis the surgical
- Bone marrow relief with all its disadvantages such as inpatient stay and surgery as a means of pain relief, the treatment of osteoarthritis currently consists only of symptomatic pain treatment and is insufficiently effective. It usually includes the permanent prescription of analgesics and / or anti-inflammatory drugs, combined with physiotherapy and weight relief, and possibly the intra-articular injection of anesthetics, corticoids or "cartilage building / replacing" substances. X-ray stimulation and acupuncture are also prescribed. The treatment of arthrosis has so far been limited to symptomatic treatment.
- the established therapies are unsatisfactory for both osteonecrosis and osteoarthritis due to the limitation to symptomatic treatment.
- the persistence of the pain-triggering mechanisms requires long-term treatment, which is associated with additional risks and costs.
- a causal treatment of the pain with permanent freedom from pain is therefore particularly desirable for osteoarthritis.
- the object was therefore to find a treatment for the diseases associated with bone marrow edema, in particular osteonecrosis and osteoarthritis, which did not only relate to the symptomatic treatment, i.e. pain relief, but also restores the structural integrity of the bone, and also to provide a drug that can be taken by the patient over a long period of time without the doctor's support.
- Prostacyclin derivatives especially the cyclodextrin clathrates of prostacyclin derivatives of the general formula I
- R 1 is a hydrogen atom or a Ci-C-io-alkyl radical
- W is a free or functionally modified on the hydroxy group
- X, Y independently of one another are a -CH 2 group or an oxygen atom
- Z is a hydrogen atom or a cyano group
- D is a straight-chain or branched saturated -CC 5 alkylene group
- E is a -C ⁇ C group or a direct bond
- R 2 is a straight-chain or branched, saturated C 1 -C 7 -alkyl group
- R 3 is a free or functionally modified hydroxyl group, and all optically active forms, racemates, diastereomers, mixtures of diastereomers, their clathrates, and if R is hydrogen, their salts with physiologically compatible bases solve the task.
- Treatment with orally available prostacyclin derivatives, in particular with cyclodextrin clathrates of prostacyclin derivatives of formula I is a novel therapy that not only suppresses the symptoms, i.e. the pain, but also combats the cause of osteonecrosis and osteoarthritis, and for the first time also clinic can be done independently.
- the alkyl group R 1 is straight-chain or branched alkyl groups with 1-10 carbon atoms, such as methyl, ethyl, propyl, 2-methylethyl, n-butyl, 1-methylpropyl, 2-methylpropyl, 1, 1-dimethylethyl (tert.- Butyl), hexyl, heptyl, octyl, nonyl, decyl.
- the alkyl group R 1 can also be substituted. Examples of substituents are fluorine, chlorine or bromine atoms, phenyl, dimethylamino, diethylamino, methoxy, ethoxy.
- Alkyl groups with 1-4 carbon atoms are preferred as the alkyl group R 1 .
- the alkyl group R 2 is straight-chain or branched, reference may be made, for example, to the radicals of corresponding chain length mentioned for R 1 , and has 1-7 carbon atoms, preferably 1-3 carbon atoms, particularly preferably 1-2.
- the hydroxyl groups in R 3 and W can be functionally modified. This means esterification or etherification.
- the ethers and / or acyl radicals thus obtained are the radicals known to the person skilled in the art.
- Ether residues are e.g. Tetrahydropyranyl, tetrahydrofuranyl, methoxymethyl, methoxyethyl, ethoxyethyl, silyl ether such as e.g. Trimethylsilyl, dimethyl tert-butylsilyl, triphenylsilyl.
- Acyl radicals can be, for example, acetyl, propionyl, butyryl, benzoyl.
- X preferably has the meaning of a CH 2 group.
- Z preferably represents a hydrogen atom.
- alkylene group D straight-chain or branched saturated alkylene group with 1-5 carbon atoms are suitable. Examples include methylene, ethylene, propylene, 1-methylethylene, butylene, 1-methylpropylene, 2-methylpropylene, pentylene, 1-methylbutylene and ethylethylene. A branched alkylene group having 3 carbon atoms is preferred.
- R 1 represents a hydrogen atom
- the compounds of the formula I can also be present as salts of physiologically compatible bases.
- Both inorganic and organic bases are suitable for salt formation.
- alkali hydroxides such as sodium or
- Potassium hydroxide alkaline earth metal hydroxides such as calcium hydroxide, ammonia, amines such as ethanolamine, diethanolamine, triethanolamine, N-methylglucamine, morpholine, tris (hydroxymethyl) methylamine.
- the prostacyclin derivatives are orally available in the sense according to the invention when they can be used for oral administration after a suitable formulation.
- prostacyclin derivatives of the general formula I formulated for oral administration: cicaprost (5 - ⁇ (E) - ( 1 S, 5S, 6S, 7R) -7-hydroxy-6 - [(3S, 4S) -3-hydroxy-4-methyl-1, 6-nonadiynyl] bicyclo [3.3.0] oct-3-ylidene ⁇ -3-oxapentanoic acid), epoprostenol ((5Z, 9, 13E, 15S) -6,9-epoxy-11,15-dihydroxy-prosta-5,13-diene-1-acid), beraprost (EP 0 084856) , Ciprostene, Taprostene, Naxaprostene, CS 570, SC-39902, FCE-22509, OP 41483
- hoprost- ⁇ -cyclodextrin clathrate for the manufacture of a medicament for the treatment of osteonecrosis and osteoarthritis is a preferred subject of the invention.
- lloprost is a prostacyclin analogue which is known from EP 11 591 and can be produced by the methods disclosed therein.
- the nomenclature name for lloprost is (5 - ⁇ (1 S, 5S, 6R, 7R) -7-hydroxy-6 - [(E) - (3R, 4RS) -3-hydro) (y-4-methyl-oct- 1-en-6-ynyl] -bicyclo [3.3.0] octan-3-ylidene ⁇ -pentanoic acid).
