Description

  

  
 



   Cette invention concerne la préparation des composés imidazoles tétracycliques, et plus particulièrement une série de   dibenzo[b,futhiépin[4,5-d3-    et   dibenzo[3,4,7,8j      cycloocta[1 ,2-d]imi    dazoles substitués en position 2 et leurs sels d'addition d'acide pharmaceutiquement acceptables en tant que nouvelle famille d'agents   anti-inflammatoires.    Selon le procédé de l'invention, on effectue la synthèse de ces composés par condensation de   ra-dicétone    appropriée, et d'un aldéhyde et d'acétate d'ammonium.



   Il n'est pas courant de trouver dans la littérature chimique des références relatives aux imidazoles polycycliques; Steck et Day,
J.   Am.    Chem. Soc., 65, 452 (1943), essayant de déterminer le cours de la réaction mise en jeu dans la formation d'imidazoles ont synthétisé une série de phénanthrimidazoles. Toutefois, aucune utilité n'a été décrite pour ces composés.



   Les agents   anti-mflammatoires    tétracycliques obtenus par le procédé de cette invention sont représentés par la formule:
EMI1.1     
 de même que leurs sels d'addition d'acide pharmaceutiquement acceptables, formule où:
 Z est un   groupement - CH2CH2 - ou    un atome S;
 chacun de X et Y est un atome d'hydrogène ou un groupement méthyle, méthoxy, un atome de fluor, de chlore, de brome ou un groupement méthylthio; et
 R est un groupement   trifluorométhyle,    pyridyle, naphtyle, phényle ou phényle substitué où le substituant est un groupement méthyle,   mèthoxy,    ou un atome de fluor, de chlore ou de brome, ou un groupement diméthylamine, carboxy ou méthylthio.



   Les composés particulièrement intéressants sont ceux dans lesquels Z est un groupement éthylène, X et Y sont des atomes d'hydrogène et R est un groupement phényle, 3-pyridyle ou   trifluorométhyle    et ceux dans lesquels Z est un atome de soufre,
X et Y sont des atomes d'hydrogène et R est un groupement p-méthoxyphényle,   3wpyridyle,      trilluorométhyle    ou p-carboxyphényle. La préparation des imidazoles tétracycliques par le procédé selon la présente invention, ayant la formule I:
EMI1.2     
 dans laquelle Z, X, Y et R sont définis comme précédemment, peut être illustré par le schéma suivant:
EMI1.3     

 La réaction illustrée   cidessus    est effectuée dans des conditions réactionnelles qui sont pratiquement celles utilisées par Davidson et al., J. Org.

  Chem., 2, 319 (1937), et cette réaction consiste à chauffer un mélange   d'r-dicétone,    d'aldéhyde ou de dérivés de ceux-ci et d'acétate d'ammonium dans un solvant qui est l'acide acétique glacial. On peut utiliser un excès d'acétate d'ammonium cinq à dix fois. La quantité d'aldéhyde utilisée par rapport à celle de dicétone peut varier depuis une quantité équimolaire jusqu'à un   excès de 100%.   



   Généralement, on considère les températures de reflux comme appropriées bien que des températures plus basses avec des durées de réaction plus longues en conséquence puissent être utilisées.



  Lorsqu'on utilise lesdites températures de reflux, des durées de réaction de 1-12 heures conviennent pour donner le produit désiré.



   Une méthode commode pour isoler le produit consiste à dilue le mélange de réaction avec de l'eau puis à neutraliser par l'hydroxyde d'ammonium jusqu'à un pH d'approximativement 7.



  Le précipité résultant est alors filtré, séché et recristallisé dans un solvant approprié.



   Les   a-dicétones    requises, dans lesquelles X et Y sont tels que définis et Z est un groupement éthylène, sont synthétisées selon le procédé préconisé par Leonard et al., J.   Am.    Chem. Soc., 77, 5078 (1955). En outre, les    -dicétones,    dans lesquelles X et Y sont tels qu'il a été indiqué et Z est le soufre, sont préparées par oxydation par l'anhydride sélénieux des monocétones correspondantes qui, de leur côté, sont préparées selon le mode opératoire Jilek et al.,
Monatsh. Chem. 96, 201 (1965). Les aldéhydes appropriés sont soit disponibles dans le commerce soit aisément préparés par l'homme de l'art selon les procédés indiqués par Carnduff, Quart. Rev., 20, 169 (1966).



   Une caractéristique des composés de formule (I) est la nature acide de l'hydrogène de l'imidazole et la propriété de former des sels avec les réactifs basiques tels que les hydroxydes, les   alkylates    ou les hydrures des métaux alcalins et les hydroxydes des métaux alcalino-terreux.



   Comme il a été indiqué antérieurement, les composés de formule (I), outre le pouvoir de former des sels avec les réactifs basiques, ont également, comme il a été indiqué antérieurement, le pouvoir de former des sels d'addition d'acide. Lesdits composés obtenus selon le procédé de l'invention peuvent être transformés en sels d'addition d'acide par interaction de la base avec un acide soit dans un milieu aqueux soit dans un milieu non aqueux.



  De la même manière, le traitement des sels d'addition d'acide par une quantité équivalente d'une solution aqueuse de base, par  exemple d'hydroxydes de métaux alcalins, de carbonates de métaux alcalins et de bicarbonates de métaux alcalins, ou par une quantité équivalente d'un cation métallique qui forme un précipité insoluble avec l'anion de l'acide, a pour résultat une régénération de la forme base libre. Pour effectuer ces transformations, le mieux est d'opérer aussi rapidement que possible et dans des conditions de température et par une méthode dictées par la stabilité desdits produits basiques. Les bases ainsi régénérées peuvent être retransformées en sel d'addition d'acide identique ou différent.



   Dans   l'utilisation    de l'activité   chimiothérapeutique    des composés obtenus selon le procédé de l'invention qui forment des sels, il est préférable naturellement d'utiliser les sels pharmaceutiquement acceptables. Bien que leur insolubilité dans Peau, leur toxicité élevée, ou leur manque de   cristallinité    puissent rendre certaines espèces salines particulières   inappropriées    ou moins appropriées à être utilisées en tant que telles dans une application pharmaceutique donnée, il est possible de transformer les sels insolubles dans   l'eau    ou toxiques en bases correspondantes pharmaceutiquement acceptables en décomposant le sel comme il a été décrit précédemment ou sinon en les transformant en un quelconque sel d'addition d'acide désiré pharmaceutiquement acceptable.



   Les exemples d'acides qui donnent des anions pharmaceutiquement acceptables sont les acides chlorhydrique, bromhydrique, iodhydrique, nitrique, sulfurique ou sulfureux, phosphorique, acétique, lactique, citrique, tartrique, succinique, maléique et gluconique.



   Comme il a été indiqué précédemment, les imidazoles tétracycliques obtenus selon le procédé de   l'invention    sont tous aisément adaptés à un usage thérapeutique comme agents antiinflammatoires chez les mammifères. Les composés suivants sont remarquables pour leur efficacité de ce point de vue: 8,9-dihydro    2-phényldibenzo[3,4,7,8]-cycloocta[1,2-d]imidazole      (I:

  Z = - CH2CH2 - ; X, Y = H    et   R = Z);      8,9-dihydro-2-(3-pyridyl       dibenzo[3,4,7,8]cycloocta[1 ,2-d]imidazole (I :Z = - CH2CH2 -;   
X, Y = H et R = 3-pyridyl);   8,9-dihydro-2-trifluorométhyl-       dibenzo[3,4,7,Sjcycloocta[1 ,2-d]imidazole (I :Z = - CH2CH2 -;   
X, Y = H et R = CF3);   2-trifluorométhyldibenzo[b,Qthiépin[4,5-d]-    imidazole (I:Z=S; X, Y=H et R=CF3);   2-(p-méthoxyphénylS      dibenzo[b,Qthiépin[4,5-d]imidazole    (I:Z=S; X, Y=H et   R=p-CH30C6H4); 2-(3-pyridyl > dibenzo[b,f]-thiépin[4,5-d]-   
 imidazole   (I: Z = S;    X, Y = H et R = 3-pyridyl) et 2-(p-carboxy   phényl)dibenzo[b,flthiépinC4,5-dlimidazo    (I:

  Z = S; X, Y = H et   R=p-HO2CC6H4).   



   Un mode opératoire habituel de détection et de comparaison des activités anti-inflammatoires des composés de cette série et dans lequel il existe une excellente corrélation avec l'efficacité chez l'homme est le test de   l'oedéme    de la patte de rat induit par la carraghénine [Winter, et al., Proc. Soc. Exp.   Biol.,    111,   544(1962)];    dans ce test, on numérote des rats albinos adultes non anesthésiés dont le poids corporel est de 150-190 g, on les pèse et on les marque à l'encre sur la malléole latérale droite. Une heure après avoir administré le médicament par gavage, on induit un oedème en injectant 0,05   ml    de solution à 1% de carraghénine dans le tissu plantaire des pattes marquées. Immédiatement après, on mesure le volume de la patte ayant reçu l'injection.

  L'augmentation de volume, trois heures après l'injection de la carraghénine, représente la réponse du rat. Les composés sont considérés actifs si la différence entre la réponse d'un témoin et celle donnée par le médicament
 à l'essai est significative. Les composés de référence sont la phényl
 butazone à 33 mg/kg et l'acide acétylsalicylique à 100 mg/kg, tous deux administrés par voie orale.



   Les imidazoles tétracycliques et leurs sels pharmaceutiquement
 acceptables, qui sont des agents anti-inflammatoires utiles, peuvent
 être administrés soit sous forme d'agents thérapeutiques séparés,
 soit sous forme de mélanges d'agents thérapeutiques. Ils peuvent
 être administrés seuls, mais sont généralement administrés avec
 un porteur pharmaceutique choisi en fonction de la voie d'admi
 nistration choisie et de la pratique pharmaceutique habituelle. Par exemple, ils peuvent être administrés par voie orale sous la forme de comprimés ou de capsules contenant des excipients tels que amidon, lactose ou certains types d'argile, etc. Ils peuvent être administrés par voie orale sous la forme d'élixirs ou de suspensions orales avec les ingrédients actifs associés à des agents émulsionnants et/ou de mise en suspension.

  Ils peuvent être injectés par voie parentérale, et dans ce cas ils peuvent, ainsi d'ailleurs que des dérivés appropriés, être préparés sous forme de solutions aqueuses stériles. Ces solutions aqueuses doivent être convenablement tamponnées, si nécessaire, et doivent contenir d'autres solutés tels que composés salins ou glucose qui les rendent isotoniques.



   Lorsqu'il s'agit de déterminer une dose efficace en thérapeutique humaine, on extrapole fréquemment les résultats obtenus dans les essais sur animaux et on considère qu'il existe une corrélation entre le comportement de l'animal dans l'essai sur animal et la dose posologique proposée pour l'homme. Lorsqu'on dispose d'une référence utilisée commercialement, on détermine fréquemment la dose du produit à examiner cliniquement chez l'homme en comparant sa performance avec le produit de référence dans un essai sur animal. Par exemple, on utilise la phénylbutazone comme agent anti-inflammatoire de référence et on l'administre à l'homme à raison de 100 à 400 mg par jour. On suppose alors que si les composés obtenus selon le procédé de l'invention ont une activité comparable à celle de la phénylbutazone dans l'essai, des doses similaires donneront des réponses comparables chez l'homme.



   C'est évidemment le médecin qui déterminera finalement la dose posologique qui sera la mieux appropriée à un individu donné, et cette dose variera avec l'âge, le poids et la réponse du patient donné de même qu'avec la nature et le degré des symptômes ainsi que les caractéristiques pharmacodynamiques de l'agent particulier à administrer. Généralement, on administre initialement des petites doses, en augmentant progressivement la dose posologique jusqu'à ce que   l'on    ait déterminé le niveau optimal. On verra souvent que lorsque la composition est administrée par voie orale il est nécessaire d'utiliser de plus grandes quantités de l'ingrédient   actifpour    obtenir le même niveau que celui produit par une petite quantité administrée par voie parentérale.



   Compte tenu de tous les facteurs précédents, une dose posologique quotidienne efficace des composés obtenus selon le procédé de l'invention, chez l'homme, est approximativement de 0,1 à 1,0 g par jour, avec une gamme préférée et d'environ 0,2 à 0,8 g par jour en une seule dose ou en doses fractionnées, ou encore d'environ 3 à 10 mg/kg de poids corporel, et allège efficacement   l'in-    flammation chez les sujets humains enclins à ces troubles. Ces valeurs sont illustratives et il peut naturellement exister des cas individuels où des doses supérieures ou inférieures soient nécessaires.



   Les exemples suivants sont donnés à titre d'illustration du procédé selon l'invention.



  Exemple   1:       8,9-dihydrn-2-(p-méthoxyphényl)dibenw[3,4,7',8]cyclo   
 octa[1 ,2-d]imidazole
   (I:Z= -CH2CH2-;    X, Y=H et R=p-CH3OC6H4).



   A une solution de 1,5 g (6,4 mmoles) de 11,12-dihydrocycloocta[a,e]dibenzène-5,6-dione dans 50   ml    d'acide acétique glacial sec contenu dans un ballon à trois tubulures et sous atmosphère d'azote, on ajoute 3,0 g d'acétate d'ammonium. On ajoute goutte à goutte à la solution jaune foncé résultante 1,1 g (7,7 mmoles) de p-méthoxybenzaldéhyde dans 10   ml    d'acide acétique glacial sec.

 

  On chauffe à reflux pendant une nuit le mélange réactionnel et ensuite on le refroidit, on le verse dans 300 ml d'eau glacée et on ajuste le pH à 7,0 en ajoutant une solution d'hydroxyde d'ammonium. On filtre le précipité résultant, on le sèche et on le recristallise dans le benzène, 385 mg,   p.f.      318-320"C.    Une seconde recristallisation dans le benzène donne l'échantillon analytique, p.f.

   A une solution chaude de 3,5 g (0,01 mole) de 8,9-dihydro2-(p-méthoxyphényl)dibenzo[3,4,7,8]cycloocta[1,2-d]imidazole dans 40   ml    de méthanol absolu, on ajoute de l'acide chlorhydrique gazeux jusqu'à la fin de la formation du précipité résultant de chlorhydrate. On refroidit la suspension dans de la glace et on filtre le précipité et on le sèche. On ajoute au filtrat un volume égal d'éther diéthylique, ce qui entraîne la précipitation d'une seconde récolte du chlorhydrate désiré. On réunit les deux fractions et on les recristallise das l'éthanol.



   D'une manière analogue, on transforme les composés obtenus selon le procédé de l'invention en leurs sels d'addition pharmaceutiquement acceptables.

EMI9.1     




   A une suspension de 23,2 g (0,209 mole) d'anhydride sélénieux dans 500 ml d'acide acétique glacial sec, sous atmosphère d'azote et chauffée à 80 C, on ajoute goutte à goutte 42,0 g (0,19 mole) de 5,6,11,12-tétrahydrobenzo[a,e]cyclooctène-5-one dans 250   ml    du même solvant. On élève la température de réaction à 110 C et on maintient cette température pendant 5 à 6 heures. On refroidit le mélange, on le verse lentement dans 2.500 ml d'un mélange glaceeau et on l'extrait plusieurs fois avec de l'acétate d'éthyle. On lave de nouveau la couche organique avec une solution saturée de bicarbonate de sodium et on sèche sur sulfate de calcium.

  On filtre le sulfate de calcium et on évapore le filtrat à sec, ce qui laisse un semi-solide jaune, qui par cristallisation dans l'éthanol fournit le produit désiré en trois fractions de cristallisation, 3,8 g, 21,3 g et 3,5 g de points de fusion respectifs 130-132 C, 126-129 C et 130-131 C On réunit ces trois récoltes et on les utilise sans autre purification.



   Leonard, et al., J. Am. Chem. Soc., 77, 5078 (1955), indique un point de fusion de 131-132 C pour cette substance, préparée par un procédé différent.



   (b) On synthétise les 5,6,11,12-tétrahydrodibenzo[a,e]cyclo- octène-5,6-diones, qui n'ont pas été indiquées jusqu'à présent dans la littérature chimique, par oxydation par l'anhydride sélénieux de la monocétone correspondante:

   This invention relates to the preparation of the tetracyclic imidazole compounds, and more particularly to a series of dibenzo [b, futhiepin [4,5-d3- and dibenzo [3,4,7,8j cycloocta [1, 2-d] imi dazoles substituted in position 2 and their pharmaceutically acceptable acid addition salts as a new family of anti-inflammatory agents. According to the process of the invention, the synthesis of these compounds is carried out by condensation of an appropriate ra-diketone, and of an aldehyde and ammonium acetate.



   It is not common to find in the chemical literature references relating to polycyclic imidazoles; Steck and Day,
J. Am. Chem. Soc., 65, 452 (1943), trying to determine the course of the reaction involved in the formation of imidazoles, synthesized a series of phenanthrimidazoles. However, no utility has been described for these compounds.



   The tetracyclic anti-inflammatory agents obtained by the process of this invention are represented by the formula:
EMI1.1
 as well as their pharmaceutically acceptable acid addition salts, formula in which:
 Z is a group - CH2CH2 - or an S atom;
 each of X and Y is a hydrogen atom or a methyl, methoxy group, a fluorine, chlorine, bromine atom or a methylthio group; and
 R is a trifluoromethyl, pyridyl, naphthyl, phenyl or substituted phenyl group where the substituent is a methyl, methoxy group, or a fluorine, chlorine or bromine atom, or a dimethylamine, carboxy or methylthio group.



   The particularly interesting compounds are those in which Z is an ethylene group, X and Y are hydrogen atoms and R is a phenyl, 3-pyridyl or trifluoromethyl group and those in which Z is a sulfur atom,
X and Y are hydrogen atoms and R is a p-methoxyphenyl, 3wpyridyl, trilluoromethyl or p-carboxyphenyl group. The preparation of tetracyclic imidazoles by the process according to the present invention, having the formula I:
EMI1.2
 in which Z, X, Y and R are defined as above, can be illustrated by the following diagram:
EMI1.3

 The reaction illustrated above is carried out under reaction conditions which are substantially those used by Davidson et al., J. Org.

  Chem., 2, 319 (1937), and this reaction consists in heating a mixture of r-diketone, aldehyde or derivatives thereof and ammonium acetate in a solvent which is acetic acid glacial. Five to ten times excess ammonium acetate can be used. The amount of aldehyde used relative to that of diketone can vary from an equimolar amount up to a 100% excess.



   Generally, reflux temperatures are considered suitable although lower temperatures with correspondingly longer reaction times can be used.



  When using said reflux temperatures, reaction times of 1-12 hours are suitable to give the desired product.



   A convenient method of isolating the product is to dilute the reaction mixture with water and then neutralize with ammonium hydroxide to a pH of approximately 7.



  The resulting precipitate is then filtered, dried and recrystallized in a suitable solvent.



   The required α-diketones, in which X and Y are as defined and Z is an ethylene group, are synthesized according to the method recommended by Leonard et al., J. Am. Chem. Soc., 77, 5078 (1955). In addition, the -diketones, in which X and Y are as indicated and Z is sulfur, are prepared by oxidation with selenious anhydride of the corresponding monocetones which, in turn, are prepared according to the procedure Jilek et al.,
Monatsh. Chem. 96, 201 (1965). Suitable aldehydes are either commercially available or readily prepared by those skilled in the art according to the methods given by Carnduff, Quart. Rev., 20, 169 (1966).



   A characteristic of the compounds of formula (I) is the acidic nature of the hydrogen of the imidazole and the property of forming salts with basic reactants such as hydroxides, alkylates or hydrides of alkali metals and hydroxides of metals. alkaline earth.



   As indicated previously, the compounds of formula (I), in addition to the power to form salts with basic reactants, also have, as indicated previously, the power to form acid addition salts. Said compounds obtained according to the process of the invention can be converted into acid addition salts by interaction of the base with an acid either in an aqueous medium or in a non-aqueous medium.



  Likewise, the treatment of acid addition salts with an equivalent amount of an aqueous solution of base, for example, of alkali metal hydroxides, alkali metal carbonates and alkali metal bicarbonates, or by an equivalent amount of a metal cation which forms an insoluble precipitate with the anion of the acid, results in regeneration of the free base form. To carry out these transformations, it is best to operate as quickly as possible and under temperature conditions and by a method dictated by the stability of said basic products. The bases thus regenerated can be converted back to the same or different acid addition salt.



   In the use of the chemotherapeutic activity of the compounds obtained according to the process of the invention which form salts, it is naturally preferable to use the pharmaceutically acceptable salts. Although their insolubility in water, their high toxicity, or their lack of crystallinity may make certain particular salt species unsuitable or less suitable for use as such in a given pharmaceutical application, it is possible to transform the insoluble salts in the water. water or toxic into corresponding pharmaceutically acceptable bases by decomposing the salt as previously described or otherwise converting them into any desired pharmaceutically acceptable acid addition salt.



   Examples of acids which give pharmaceutically acceptable anions are hydrochloric, hydrobromic, hydriodic, nitric, sulfuric or sulfurous, phosphoric, acetic, lactic, citric, tartaric, succinic, maleic and gluconic acids.



   As indicated above, the tetracyclic imidazoles obtained according to the process of the invention are all easily suitable for therapeutic use as anti-inflammatory agents in mammals. The following compounds are notable for their efficacy from this point of view: 8,9-dihydro 2-phenyldibenzo [3,4,7,8] -cycloocta [1,2-d] imidazole (I:

  Z = - CH2CH2 -; X, Y = H and R = Z); 8,9-dihydro-2- (3-pyridyl dibenzo [3,4,7,8] cycloocta [1, 2-d] imidazole (I: Z = - CH2CH2 -;
X, Y = H and R = 3-pyridyl); 8,9-dihydro-2-trifluoromethyl-dibenzo [3,4,7, Sjcycloocta [1, 2-d] imidazole (I: Z = - CH2CH2 -;
X, Y = H and R = CF3); 2-trifluoromethyldibenzo [b, Qthiepin [4,5-d] - imidazole (I: Z = S; X, Y = H and R = CF3); 2- (p-methoxyphenylS dibenzo [b, Qthiépin [4,5-d] imidazole (I: Z = S; X, Y = H and R = p-CH30C6H4); 2- (3-pyridyl> dibenzo [b, f] -thiepin [4,5-d] -
 imidazole (I: Z = S; X, Y = H and R = 3-pyridyl) and 2- (p-carboxy phenyl) dibenzo [b, flthiepinC4,5-dlimidazo (I:

  Z = S; X, Y = H and R = p-HO2CC6H4).



   A usual procedure for the detection and comparison of the anti-inflammatory activities of the compounds of this series and in which there is an excellent correlation with the efficacy in humans is the test for rat paw edema induced by carrageenan [Winter, et al., Proc. Soc. Exp. Biol., 111, 544 (1962)]; in this test, non-anesthetized adult albino rats with a body weight of 150-190 g were numbered, weighed and ink marked on the right lateral malleolus. One hour after administration of the drug by gavage, edema is induced by injecting 0.05 ml of 1% solution of carrageenan into the plantar tissue of the marked paws. Immediately afterwards, the volume of the injected paw is measured.

  The increase in volume, three hours after the injection of carrageenan, represents the response of the rat. Compounds are considered active if the difference between the response of a control and that given by the drug
 on trial is significant. The reference compounds are phenyl
 butazone 33 mg / kg and acetylsalicylic acid 100 mg / kg, both administered orally.



   Tetracyclic imidazoles and their pharmaceutical salts
 acceptable, which are useful anti-inflammatory agents, may
 be administered either as separate therapeutic agents,
 or in the form of mixtures of therapeutic agents. They can
 be administered alone, but are usually administered with
 a pharmaceutical carrier chosen according to the route of administration
 chosen administration and usual pharmaceutical practice. For example, they can be administered orally in the form of tablets or capsules containing excipients such as starch, lactose or certain types of clay, etc. They can be administered orally in the form of elixirs or oral suspensions with the active ingredients combined with emulsifying and / or suspending agents.

  They can be injected parenterally, and in this case they can, as well as suitable derivatives, be prepared in the form of sterile aqueous solutions. These aqueous solutions should be properly buffered, if necessary, and should contain other solutes such as saline compounds or glucose which make them isotonic.



   When it comes to determining an effective dose in human therapy, the results obtained in animal tests are frequently extrapolated and it is considered that there is a correlation between the behavior of the animal in the animal test and the proposed dosage dose for humans. When a commercially used reference is available, the dose of the product to be examined clinically in humans is frequently determined by comparing its performance with the reference product in an animal test. For example, phenylbutazone is used as the standard anti-inflammatory agent and is administered to humans at a rate of 100 to 400 mg per day. It is then assumed that if the compounds obtained according to the process of the invention have an activity comparable to that of phenylbutazone in the test, similar doses will give comparable responses in humans.



   It is of course the physician who will ultimately determine the dosage dose that will be most appropriate for a given individual, and this dose will vary with the age, weight and response of the given patient as well as with the nature and degree of the effects. symptoms as well as the pharmacodynamic characteristics of the particular agent to be administered. Usually small doses are given initially, gradually increasing the dosage until the optimum level has been determined. It will often be seen that when the composition is administered orally it is necessary to use larger amounts of the active ingredient to achieve the same level as that produced by a small amount parenterally.



   In view of all the foregoing factors, an effective daily dosage dose of the compounds obtained according to the process of the invention, in humans, is approximately 0.1 to 1.0 g per day, with a preferred range and about 0.2 to 0.8 g per day in a single dose or in divided doses, or about 3 to 10 mg / kg of body weight, and effectively alleviates inflammation in human subjects prone to these troubles. These values are illustrative and there may of course be individual cases where higher or lower doses are required.



   The following examples are given by way of illustration of the process according to the invention.



  Example 1: 8,9-dihydrn-2- (p-methoxyphenyl) dibenw [3,4,7 ', 8] cyclo
 octa [1, 2-d] imidazole
   (I: Z = -CH2CH2-; X, Y = H and R = p-CH3OC6H4).



   To a solution of 1.5 g (6.4 mmol) of 11,12-dihydrocycloocta [a, e] dibenzene-5,6-dione in 50 ml of dry glacial acetic acid contained in a three-necked flask and under nitrogen atmosphere, 3.0 g of ammonium acetate are added. To the resulting dark yellow solution, 1.1 g (7.7 mmol) of p-methoxybenzaldehyde in 10 ml of dry glacial acetic acid are added dropwise.

 

  The reaction mixture was refluxed overnight and then cooled, poured into 300 ml of ice water and the pH adjusted to 7.0 by adding ammonium hydroxide solution. The resulting precipitate is filtered, dried and recrystallized from benzene, 385 mg, m.p. 318-320 ° C. A second recrystallization from benzene gives the analytical sample, m.p.



     321-323 C.

   To a hot solution of 3.5 g (0.01 mole) of 8,9-dihydro2- (p-methoxyphenyl) dibenzo [3,4,7,8] cycloocta [1,2-d] imidazole in 40 ml of absolute methanol, gaseous hydrochloric acid is added until the formation of the resulting hydrochloride precipitate is complete. The suspension is cooled in ice and the precipitate is filtered off and dried. An equal volume of diethyl ether is added to the filtrate, resulting in precipitation of a second crop of the desired hydrochloride. The two fractions are combined and recrystallized in ethanol.



   In an analogous manner, the compounds obtained according to the process of the invention are converted into their pharmaceutically acceptable addition salts.

EMI9.1




   To a suspension of 23.2 g (0.209 mol) of selenious anhydride in 500 ml of dry glacial acetic acid, under a nitrogen atmosphere and heated to 80 ° C., is added dropwise 42.0 g (0.19 mole) of 5,6,11,12-tetrahydrobenzo [a, e] cyclooctene-5-one in 250 ml of the same solvent. The reaction temperature is raised to 110 ° C. and this temperature is maintained for 5 to 6 hours. The mixture is cooled, poured slowly into 2,500 ml of an ice-water mixture and extracted several times with ethyl acetate. The organic layer is washed again with saturated sodium bicarbonate solution and dried over calcium sulfate.

  The calcium sulfate is filtered off and the filtrate is evaporated to dryness, leaving a yellow semi-solid, which on crystallization from ethanol gives the desired product in three crystallization fractions, 3.8 g, 21.3 g and 3.5 g of respective melting points 130-132 C, 126-129 C and 130-131 C These three crops are combined and used without further purification.
