Si è quindi filtrato il precipitato, lo si è lavato con etanolo quindi con diisopropilossido e lo si è essiccato durante la notte a pressione ridotta a 65& ottenendo così 20,7 grammi del composto del titolo. Si sono concentrati i liquidi di lavaggio e si è trattato il residuo ottenuto con etanolo, lo si è filtrato, lavato con etanolo, quindi con dietil-etere e si sono ottenuti così 4,5 grammi del composto del titolo (resa totale 86%). In a 1 liter reactor equipped with stirring and cooling media and placed under nitrogen circulation, 40 grams (0.078 moles) of 5- (2-chlorophenyl) -8- / 4- (methoxy) phenylthiocarbammoyl / - were poured. 6,7,8,9-tetrahydro-3H-pyridium 4 \ 3 *: 4,5 / thieno / 3.2-1 'J 1,4-diazepine-2-thione and 350 ml of tetrahydrof urane. Then, the mixture was cooled to 103⁄4 and 4.1 ml (0.081 mol) of hydrazine hydrate was added. It was achieved in 15 minutes. A brown-red solution was thus obtained containing a slight dark precipitate which was then filtered. 9/10 of tetrahydrophurane were then evaporated and 400 ml of absolute ethanol were added to the residue. There was precipitation after carrying out the primer. The mixture was stirred on an ice bath for 1 hour. The precipitate was then filtered, washed with ethanol, then with diisopropyloxide and dried overnight under reduced pressure at 65% thus obtaining 20.7 grams of the title compound. The washing liquids were concentrated and the residue obtained was treated with ethanol, filtered, washed with ethanol, then with diethyl-ether and thus 4.5 grams of the title compound were obtained (total yield 86%) .

I) Inibizione dell’aggregazione di piastrine provocata da PAF I) Inhibition of platelet aggregation caused by PAF
Si è effettuata questa sperimentazione secondo il metodo di R. Kinlough. Rethbone, J.P. Cazenave, M. Packham e F. Mustard, Lab. Investi. 48, 98, 1980. In questa prova, si sono usati conigli della Nuova Zelanda (conigli maschi della Nuova Zelanda aventi un peso medio di S kg). This experimentation was carried out according to the method of R. Kinlough. Rethbone, J.P. Cazenave, M. Packham and F. Mustard, Lab. Invest. 48, 98, 1980. In this test, New Zealand rabbits (male New Zealand rabbits having an average weight of S kg) were used.
Si sono effettuate le determinazioni su un aggregometro Coultronics chrono-log, a 57?? collegato con un registratore grafico; i risultati di queste determinazioni (in concentrazione molare) sono riportati nella tabella I nella colonna centrale. The determinations were made on a Coultronics chrono-log aggregometer, at 57 ?? connected with a graphic recorder; the results of these determinations (in molar concentration) are reported in Table I in the central column.
2) Inibizione del legame verso ricettori di benzotiazepine 2) Inhibition of binding to benzothiazepine receptors
L’interesse -della sperimentazione precedente dipende dai risultati ottenuti in questa sperimentazione: poiché un composto della presente invenzione ha una struttura simile a quella delle benzotiazepine, è importante verificare se l’attività specifica di benzotiazepine non si presenti in corrispondenza della dose alla quale l’aggregazione delle piastrine è stata impedita. The interest of the previous experiment depends on the results obtained in this experiment: since a compound of the present invention has a structure similar to that of benzothiazepines, it is important to verify whether the specific activity of benzothiazepines does not occur at the dose at which the platelet aggregation was prevented.
Pertanto, si è effettuata questa sperimentazione secondo il metodo di Mohler H. e Richard J.G. Agonist and antagonis benzodiazepine recptor interaction in vitro, Nature, Voi. 294, 763-765, 1981. Therefore, this experimentation was carried out according to the method of Mohler H. and Richard J.G. Agonist and antagonis benzodiazepine recptor interaction in vitro, Nature, Vol. 294, 763-765, 1981.
Si è effettuata questa sperimentazione su cervelli di ratto sottoposti ad incubazione per 1 ora e 30 minuti a 4C usando H-RO- 15-1788 e ■^H-R 0-5-4864 (NEN) come tracciati e usando RO- 15-4788 e RO-5-4864 come antagonisti di riferimento. This experiment was performed on rat brains subjected to incubation for 1 hour and 30 minutes at 4C using H-RO- 15-1788 and ■ ^ H-R 0-5-4864 (NEN) as plots and using RO- 15-4788 and RO-5-4864 as reference antagonists.
I risultati in concentrazione molecolare sono riportati nella tabella I, sulla colonna di destra. The results in molecular concentration are shown in Table I, on the right column.
31 Azione sul broncospasmo provocato da PAF 31 Action on PAF-induced bronchospasm
Un’iniezione endovenosa di PAF effettuata in porcellini d'india anestetizzati provoca una broncocostrizione con leucopenia e con trombocitopenia, secondo il metodo descritto in S. Desquand, C. Touvay, J. Randon, V. Lagente, B. Vilain, I. Maridonneau-Parini, A. Etienne, J. Lefort, P. Braquet e B. Vargaftig. Interference of BN 52021 (Ginkolide B) with thè bronchpulmonary effects of PAF-acether in thè guinea-pig. Eur. J. Pharmacol. 127 : 83-95, 1986. An intravenous injection of PAF carried out in anesthetized guinea pigs causes bronchoconstriction with leukopenia and thrombocytopenia, according to the method described in S. Desquand, C. Touvay, J. Randon, V. Lagente, B. Vilain, I. Maridonneau -Parini, A. Etienne, J. Lefort, P. Braquet and B. Vargaftig. Interference of BN 52021 (Ginkolide B) with the bronchpulmonary effects of PAF-acether in the guinea-pig. Eur. J. Pharmacol. 127: 83-95, 1986.
Porcellini d’ìndia maschi di Hartley (400+450 g) (Charles River) anestetizzati con uretano (2 g/kg IP), quindi tracheotomizzati e sottoposti a respirazione forzata con una pompa di respirazione : 70-80 corse/mm, 1 mi di aria/ 100 per ogni corsa. Si introduce un catetere nella rena iugulare per effettuare le iniezioni e si introduce un altro catetere nell'arteria carotide per prelievi di sangue. La resistenza iniziale viene mantenuta costante sotto una pressione di 10 cm di acqua secondo il metodo di Konzett e RÒssler e l'aria in eccesso viene misurata con un trasduttore per broncospasmo UGO BASILE insieme con un registratore GEMINI. Ai porcellini d’india si è praticata un'iniezione IV di pancuronium (Pavulon) per inibire la loro respirazione spontanea. Male Hartley Guinea pigs (400 + 450 g) (Charles River) anesthetized with urethane (2 g / kg IP), then tracheostomized and forced breathing with a breathing pump: 70-80 strokes / mm, 1 mi of air / 100 for each stroke. A catheter is introduced into the jugular kidney for injections and another catheter is introduced into the carotid artery for blood sampling. The initial resistance is kept constant under a pressure of 10 cm of water according to the method of Konzett and RÒssler and the excess air is measured with a UGO BASILE bronchospasm transducer together with a GEMINI recorder. The guinea pigs were given an IV injection of pancuronium (Pavulon) to inhibit their spontaneous breathing.
Si sono preparati il composto secondo la presente invenzione e il composto di riferimento WEB 2086 (vedi il brevetto Boehringer citato sopra) sotto forma di una sospensione in acqua gommosa che è stata somministrata per via orale 2 ora prima della stimolazione con il PAF. The compound according to the present invention and the reference compound WEB 2086 (see Boehringer patent cited above) were prepared in the form of a rubbery suspension in water which was administered orally 2 hours before stimulation with the PAF.
La broncocostrizione viene predisposta mediante il calcolo della percentuale di broncocostrizione Δ. x 100 Bronchoconstriction is set up by calculating the percentage of bronchoconstriction Δ. x 100
in cui A indica una broncocostrizione provocata espressa in mm e B indica una broncocostrizione massima in mm. where A indicates a provoked bronchoconstriction expressed in mm and B indicates a maximum bronchoconstriction in mm.
