Description
PIAZEPIN-INPOI.ES. AS INHIBITORS OF PHOSPHODIESTERASE IV
Field of the Invention The present invention relates to the use of
[1, 4] diazepin [6,7, l-hi] indoles, some of which are novel, in the preparation of medications that make possible the treatment of disorders for which therapy by a phosphodiesterase IV inhibitor is relevant . These drugs are useful, in particular, as anti-inflammatory agents, antiallergic agents, bronchodilators or antasmáticos, and lack side effects in the digestive system or the heart.
Technical Background of the Invention In contrast to the properties described by the present invention, the prior art proposes [1, 4] diazepin [6,7, l-hi] indoles, for which the antagonistic properties with respect to the colecisto-quinina (CCK) and / or gastrina, and which are proposed for disorders of the digestive tract: stomach, intestine, pancreas and gall bladder and, in particular, for disorders of satiety. Thus, European Patent Application No. 340 064 describes compounds of the formula:
wherein R ^ and R2 are hydrogen or halogen, Ar is indolyl or phenyl and n is 2 or 3. These compounds are peripheral antagonists of cholecystokinin (CCKA). European Patent Application No. 360 079 discloses peripheral and / or central CCK antagonist compounds of the formula:
wherein R1 is optionally substituted aryl, X is oxygen or methylene, which is optionally substituted by a lower alkyl radical, A is a bond or lower alkylene, which may carry one or more lower alkyl groups and R2 is hydrogen or acyl, in an excessively broad sense. In fact, it appears that the preferred products of this application, EP 360 079, are those in which: R1 is 2-fluorophenyl and / or - R2 is an aryl-propenoyl or heteroaryl-propenoyl group, and / or the configuration about The carbon of diazepine in the position aa its carbonyl function is (S) or (R, S). With respect to the inhibition of phosphodiesterases, it is recalled that the 3 ', 5'-cyclic adenosine monophosphate (cAMP) is a secondary intracellular universal messenger, intermediate between a primary messenger (a hormone, neurotransmitter or autocoid) and functional responses Cellular: the primary messenger stimulates the enzyme, which is responsible for the synthesis of cAMP and this cAMP acts, depending on the cells in question, in a large number of functions: metabolic, contractile or secretory. The effects of the cAMP end, when broken by the cyclic nucleotide phosphodiesterases, which are intracellular enzymes that catalyze their hydrolysis to 5-monophosphate. of inactive adenosine. In mammals, a distinction is made between at least five major classes of cyclic nucleotide phosphodiesterases (PDEs) numbered I to V, according to their structure, their kinetic characteristics, their substrate specificity or their sensitivity to effectors (Beavo JA (1990) Trenas Pharmacol, Sci. 11, 150-155). The PDEs IV are specific to the cAMP. Non-specific phosphodiesterase inhibitor compounds are known, which inhibit various classes of enzymes. This is the case for some methylxanthines, such as theophylline. These compounds have a therapeutic index that results in particular from their action on types of PDEs present in the cells, different in the target cells. In contrast, some classes of PDEs can be selectively inhibited by several pharmacological agents: the hydrolysis of the cyclic nucleotides is reduced and thus their concentration increases only in those cells that contain the type of PDE that is sensitive to the inhibitor. Particular interest is evident for phosphodiesterases IV (PDE IV), which have been identified in numerous tissues including those of the central nervous system, heart, vascular endothelium, vascular and respiratory smooth muscle and myeloid lines and lymphoid An increase in cAMP in the cells involved in inflammation inhibits its activation: the inhibition of the synthesis and release of mediators at the level of the asto-cytos, monocytes, eosinophil and basophil polymorphonuclear leukocytes, inhibition of chemotaxis and degranulation of neutrophil and eosinophil polymorphonuclear leukocytes, and the inhibition of lymphocyte divisions and differentiation. Cytokines, especially TNF and interleukins, produced by different types of leukocytes, for example T lymphocytes and eosinophil polymorphonuclear leukocytes, play an important role in the onset of inflammatory manifestations, especially in response to stimulation by an allergen. at the level of the respiratory tracts. On the other hand, cAMP reduces the tone of the smooth muscle fibers of the respiratory tract; Inhibitors of PDE IV produce bronchial relaxation. Therefore, it is possible to expect selective PDE IV inhibitors to possess therapeutic activity such as anti-inflammatory drugs, antiallergic drugs and bronchodilators and in the treatment of asthma, where the infiltration of the respiratory tract by inflammatory cells and bronchoconstriction are observed. .
Theophylline has been widely used for a long time in the treatment of asthma and, although its mechanism of action is complete, inhibition of PDE contributes to its action, but also to certain undesired effects, such as nausea and headache. . However, the development of potent inhibitors of PDE IV, up to now, has proven difficult, due to the fact that many potential inhibitors of PDE IV do not lack activity in phosphodiesterases from other classes. The lack of selectivity of the PDE IV inhibitors, therefore, represents a problem, given the extension of the functions regulated by the cAMP. Therefore, there is a need for potent PDE IV inhibitors that are selective, ie do not have an action on PDEs that belong to other classes. The rolipram (INN), a derivative of pyrrolidone, first synthesized in 1975, is considered representative of the specific inhibitors of PDE IV. Numerous compounds related to rolipram have been synthesized, with a view to their use as inhibitors of PDE IV. The rolipram, in vitro, inhibits the activity of inflammatory cells in rodents: the inhibition of mediator synthesis by mast cells, eosinophil and basophil polymorphonuclear leukocytes and monocytes; inhibition of chemotaxis and degranulation of polymorphonuclear leukocytes. Rolipram has been proposed as an antidepressant; however, its use is accompanied by unwanted effects of the type that involve nausea and vomiting.
Compendium of the Invention Turning now to the prior art, it has been found that derivatives of [1,4] diazepin [6, 7, 1-hi], some of which are novel, are - surprisingly - potent inhibitors of the PDE IV at concentrations where they have little or no action in the other PDE classes.

the second stage consists of the catalytic reduction of the oxime by hydrogen, in the presence of a reduction catalyst or by the reaction with zinc, in the presence of acetic acid or with stannous chloride, in the presence of hydrochloric acid, to obtain the amine derivative (II). The following equation illustrates the process of the synthesis of (II):
The indole (IX) is reduced to the corresponding indoline (VIII), which is condensed with benzonitrile (VII) in the presence of a Lewis acid, to give, after hydrolysis, the benzophenone (VI). The preparation of (VI), in the presence of ethyl glycinate in pyridine, of the product of the formula (V), is adapted from the method described (method N) by Hester J.

Biological Section
Phosphodiesterase - inhibitory activity The ability of the compounds of the formula (I) of the invention to inhibit cyclic nucleotide phosphodiesterases by measuring their IC 50 (concentration required to inhibit enzymatic activity by 50%) was evaluated. In the case of PDE IV, this value was compared with the IC50 of rolipram, a specific inhibitor of PDE IV, by the ratio of the IC50 of rolipram to the IC50 of the product to be tested, with respect to the same enzyme preparation.
The different classes of phosphodiesterases were obtained in partially purified form from a DEAE-cellulose column of the trachea of guinea pigs and aortas of dogs, according to a method adapted from WJ Thompson et al., 1979, in Advances in Cyclic Nucleotide Research , Vol. 10: 69-92, Ed. G. Brooker et al. , Raven Press, New York, and of P. J. Silver et al. , 1988, Eur. J. Pharmacol. 150: 85-94. Subsequently, the measurement of the enzymatic activity of the different classes of the PDEs and, in particular, of the PDEs IV was carried out, according to a method that was similarly adopted from that of W. J. Thompson, ibidem. For the determination of the IC 50, the enzymatic activity was measured in the presence of the inhibitor, in the range of concentrations of 0.1 to 100 μM. The following table illustrates the inhibitory activity of PDE IV compared to that of rolipram, for an enzyme preparation obtained from guinea pig trachea.
Table l; Inhibitory effect of PDE IV, compared to rolipram
An examination of the results of the above table shows that the products of the invention, tested in the study, generally inhibit the PDE IV enzyme from the guinea pig trachea more efficiently than the rolipram, and in a number of cases is from two to three times more active than the rolipram. Likewise, the studies carried out in the PDEs of different classes, purified from the tracheae of guinea pigs or dog aortas, showed that the IC 50 values obtained with the products of the invention, in relation to the PDEs of the class III and of class I and V, are much larger than the measures for PEDs of class IV.
These results are strong evidence of a potent and selective inhibitory activity of the products of the invention, in relation to the PDE IV.
Anti-inflammatory and antiallergic activity in vivo The effects of the products of the invention on guinea pigs were studied in a model of eosinophilic infiltration induced by antigenic stimulation or by exposure to a PAF aerosol, according to the methodology described by Lagente V et al. al , (1994) Br. J. Pharmacol. 112, 83P. The administration of the products of the examples (1-30 mg / kg, p.o.) significantly reduces the number of eosinophils in the bronchoalveolar lavage fluid. The administration of the products of the invention also reduces the inflammatory responses induced by the intratracheal instillation of IL-5 in the guinea pig.
Inhibition of cytokine secretion The activity of the products of the invention in the secretion of cytokines by human mononuclear leukocytes was measured, in vitro, according to the method described by Konno S. et al. , (1994) Eur. J. Pharamacol. 264: 265-268 and Endo H et al. , (1993) Int. Arch. Allergy Immunol. , 101: 425-430 for the interleukins. and by Semmler J et al. , (1993) Int. J. Immunopharmac. 15: 409-413 and Vergese M..
et al. , (1995) J. Pharmacol. Exp. Ther. 272_1313-1320 for TNFa, was carried out by an immunoenzyme method. The IC 50 concentration was calculated, which inhibits cytokine production by 50%, as stimulated by concanavalin A, phytohemagglutinin or lipopolysaccharides. Under these conditions, the products (I) of the invention that were tested, showed a marked inhibitory activity, with the IC 50 values, which are generally less than or equal to 10 ~ 5 mol. I "1.
Toxicoloqia Subacute oral toxicity was studied in Example
2. V in the rat. When administered for two weeks, as a 1% aqueous suspension in methylcellulose, at a dose of 100 mg / kg / day, the product showed no activity that could be linked with a toxic effect. In particular, the absence of emetic effects was confirmed in the dog. The products of Examples 4 and 9.B, at an intravenous dose of 3 mg / kg, showed no emetic effects. These results demonstrate the anti-inflammatory and / or immunosuppressive activity of the products of the invention. Therefore, the products of the invention will be particularly useful for the treatment or prevention: of allergic pathologies and especially asthma and atopic dermatitis; of inflammatory pathologies, especially of the bronchial region, but also rheumatoid arthritis and inflammatory bowel disorders (hemorrhagic rectocolitis and Crohn's disease); which include cases where there is an autoimmune component.
Pharmaceutical Section The Products of the invention were administered in the form of compositions that are appropriate to the nature and severity of the disorder to be treated. The daily dose for humans is commonly between 2 mg and 1 g of the product, which can be taken in one or more individual doses. The compositions are prepared in forms that are compatible with the intended route of administration, for example, tablets, coated tablets, capsules, mouthwashes, aerosols, powders for inhalation, suppositories, gels or suspensions. These compositions are prepared by methods that are familiar to the person skilled in the art and comprise from 0.5 to 60% by weight of the active principle
