Jest to zwiazek nowy i moze znalezc zastosowanie jako srodek leczniczy.Wedlug wynalazku nowy zwiazek wytwarza sie przez wprowadzanie grupy etylowej do l-(2-cyja- nofenoksy)-2-hydroksy-3-aminopropanu o wzorze 2 droga reakcji z elektrofilowym zwiazkiem o wzo¬ rze 3, w którym X oznacza latwo- odszczepialna anionowa grupe, taka jak atom chlorowca, grupa kwasu siarkowego albo grupa alkilo-, wzglednie arylosulfonyloksylowa.Produkty wyjsciowe sa czesciowo znane, czes¬ ciowo zas moga byc otrzymywane w znany spo¬ sób, zwlaszcza przy uzyciu l-(2-cyjanofenoksy)-2,3- -epoksypropanu jako zwiazku wyjsciowego. Zwia¬ zek epoksydowy o wzorze 2 mozna otrzymywac przez reakcje 2-hydroksy-benzonitrylu z epichlor- hydryna w obecnosci lugu sodowego, a przez dzia¬ lanie odpowiednim kwasem chlorowcowodorowym otrzymuje sie chlorowcohydryne o wzorze 2.Zwiazek o wzorze 2 mozna tez otrzymac z epok¬ sydu o wzorze 4 przez reakcje z ftalimidkiem po¬ tasowym i nastepne rozszczepienie hydrazyny (syn¬ teza Gabriela).Wytworzony sposobem wedlug wynalazku zwia¬ zek posiada w ugrupowaniu -CHOH- asymetrycz¬ ny atom wegla; wystepuje wiec zarówno w for¬ mie racematu, jak równiez optycznie czynnych antypodów. Optycznie czynne zwiazki mozna otrzymac albo wychodzac z optycznie czynnych produktów wyjsciowych, albo rozdzielajac otrzy- many racemat na antypody optyczne w znany spo¬ sób, na przyklad za pomoca kwasu dwubenzoilo- winowego lub bromokamforosulfonowego.Wytworzony sposobem wedlug wynalazku zwia¬ zek mozna przeprowadzic w znany sposób w fizjo- io logicznie tolerowane sole addycyjne z kwasami.Do tego celu nadaje sie, na przyklad kwas solny, bromowodorowy, siarkowy, metanosulfonowy, ma¬ leinowy, octowy, szczawiowy, mlekowy, winowy albo 8-chloro-teofilina.Wytworzony sposobem wedlug wynalazku zwia¬ zek o wzorze 1, wzglednie jego fizjologicznie tole¬ rowane sole addycyjne z kwasami, posiadaja cen¬ ne wlasciwosci terapeutyczne, szczególnie /?-adre- nolityczne i moga byc podawane leczniczo lub pro- filaktycznie w schorzeniach naczyn wiencowych serca, w leczeniu arytmii serca, szczególnie czesto¬ skurczu. Zwiazek ten wykazal w badaniach na swinkach morskich znacznie skuteczniejsze dziala¬ nie zwalniajace akcje serca i antagonistyczne w stosunku do aludryny [aludryna = l-(3,4-dwu- hydroksyfenylo)- 1- hydroksy- 2- izopropyloamino- etan] oraz mniejsza toksycznosc niz znany 1-(1- -naftoksy)-2-hydroksy-3-izopropyloaminopropan.Jednorazowa dawka otrzymanego sposobem we- dlug wynalazku zwiazku wynosi 1—150 mg, ko- 84 33984 339 rzystnie 5—50 mg (doustnie) wzglednie 1—20 mg (pozajelitowo). — Z otrzymanego sposobem wedlug wynalazku zwiazku przygotowuje sie zwykle stosowne posta¬ cie galenowe, takie jak roztwory, emulsje, tablet¬ ki, drazetki albo postacie o przedluzonym dziala¬ niu, w znany sposób przy uzyciu srodków pomoc¬ niczych, nosników, srodków rozsadzajacych, wia¬ zacych, powlekajacych albo poslizgowych, smako¬ wych^ slodzacych, srodków do osiagniecia przedlu¬ zonego dzialania albo ulatwiajacych rozpuszczanie.Nowy zwiazek moze byc równiez stosowany w polaczeniu z innymi farmakologicznie czynnymi subsialacjami rozszerzajacymi naczynia wiencowe, pobudzajacymi uklad wspólczulny, glikozydami na- sercowymi albo srodkami uspokajajacymi.Ta&lfctki mo^na na przyklad otrzymywac przez zmieszanie substancji czynnej ze znanymi substan- cjamF'pomocniczymi, na przyklad obojetnymi roz¬ cienczalnikami, takimi jak weglan wapniowy, fos¬ foran wapniowy albo cukier mlekowy, srodkami rozsadzajacymi, takimi jak skrobia kukurydziana lub kwas alginowy, srodkami wiazacymi, takimi jak skrobia albo zelatyna, srodkami poslizgowymi, takimi jak stearynian magnezowy albo talk i/lub srodkami do uzyskania przedluzonego dzialania, ta¬ kimi jak karboksypolimetylen, karboksymetyloce- luloza, ftalan acetylocelulozy albo octan poliwi- nylu.Tabletki moga równiez skladac sie z wielu warstw. Drazetki mozna otrzymywac odpowiednio przez powlekanie otrzymanych analogicznie do tabletek rdzeni w znany sposób przy uzyciu sto¬ sowanych zwykle do drazowania srodków, takich jak kolidon, szelak, guma arabska, talk, dwutlenek tytanu albo cukier. Dla uzyskania efektu przedlu¬ zonego dzialania albo unikniecia niezgodnosci rdzen moze skladac sie z kilku warstw.Podobnie dla uzyskania przedluzonego dzialania powloki drazetek moga równiez zawierac kilka warstw, przy czym stosuje sie w tym celu wymie¬ nione przy tabletkach substancje pomocnicze.Dla wytwarzania miekkich kapsulek zelatyno¬ wych albo podobnych kapsulek zamykanych, sub¬ stancje czynna mozna mieszac z olejem roslinnym.Twarde kapsulki zelatynowe moga zawierac gra¬ nulat substancji czynnej w polaczeniu ze stalymi sproszkowanymi nosnikami, takimi jak laktoza, sacharoza, sorbit, mannit, skrobia, na przyklad skrobia ziemniaczana, kukurydziana albo amylo- pektyna, pochodne celulozy albo zelatyna.Syropy substancji czynnej lub tez kombinacji substancji czynnych moga zawierac jeszcze do¬ datkowo srodek slodzacy, jak sacharyna, cyklami- nian, gliceryna, albo cukier, jak równiez srodek poprawiajacy smak, na przyklad srodki zapacho¬ we, jak wanilina albo ekstrakt pomaranczowy.Oprócz tego moga zawierac jeszcze srodki ulatwia¬ jace powstawanie zawiesiny, zagestniki takie, jak sól sodowa karboksymetylocelulozy, srodki zwil¬ zajace, na przyklad produkty kondensacji alko^ holi tluszczowych z tlenkiem etylenu, albo srodki konserwujace, takie jak /?-hydroksybenzoesany.Roztwory iniekcyjne przygotowuje sie w znanym sposób, na przyklad z dodatkiem srodków konser¬ wujacych, takich jak /?-hydroksybenzoesany albo stabilizatorów, takich jak kompleksony i rozlewa do fiolek iniekcyjnych lub ampulek.
