Description

Wedlug niniejszego wynalazku do¬ chodzi sie do nowego i swoistego pola¬ czenia z kwasu dwuetylobarbiturowego i dwumetyloamino-fenylo-dwumetylopy- razolonu, jezeli stopic ze soba te dwa skladniki.W tym celu stapia sie ze soba 462 cz. dwumetyloamino-fenylo-dwumetylo- pyrazolonu z 184 cz. kwasu dwuetylo¬ barbiturowego, przyczem temperatura nie powinna przekroczyc 110°. Przezro¬ czysty, zólty stop traktuje sie po zasty¬ gnieciu woda i oczyszcza. Powstaly zwia¬ zek topi sie przy 95° — 97° i jest rozpu¬ szczalny w goracej wodzie, alkoholu, ete¬ rze i innych rozpuszczalnikach organicz¬ nych. Analiza wykazala wzór C34H40O5N8.Obliczono, ze N stanowi 17,34 proc. Zna¬ leziono 17,34 proc. i 17,51 proc.Nowy zwiazek chemiczny ma znalezc zastosowanie jako srodek usmierzajacy ból, poniewaz wzmocniono w nim nie dzialanie nasenne, lecz analgetyczne. Jest to wazne, poniewaz dla celowego sto¬ sowania analgeticum, szczególnie dla usmierzenia bólu glowy, nalezy sie sta¬ rac, aby usmierzenie bólu bylo umozli¬ wione bez dzialania nasennego i aby w ten sposób nie naruszyc zdolnosci do pracy.- W nowym zwiazku nie ma sie do czynienia z zadna sola, np. w rodzaju znanych soli kwasów dwualkilobarbitu- rowych, wzgl. ar-alkilo-barbiturowych z zasadami organicznemi, wzgl. soli fe¬ ny lo-dwumetylopyrazolonu lub dwume- tylo-amino-fenylo-dwumetylopyrazolonu z kwasami organicznemi lub amidami kwasów. Te sole w zaden sposób nie róznia sie kolorem od substancji macie-rzystych, podczas gdy w przedlozonym wynalazku z bialych substancyj wyjscio¬ wych otrzymuje sie zwiazek, który jest zólty. Juz ta okolicznosc wskazuje, ze w zgloszonym sposobie zachodzi prze¬ miana czasteczkowa.Nowy zwiazek zachowuje sie wobec tego chemicznie równiez zupelnie ina¬ czej, jak wzmiankowane sole. Podczas gdy u tych ostatnich reakcja oddzielnych materjalów W3'jsciowych otrzymuje sie niezmieniona, nie zachodzi to z przyto¬ czonym zwiazkiem. Tak wiec dwumetylo- amino - fenylo - dwumetylopyrazolon daje przy umiarkowanem ogrzewaniu z woda utleniona i kwasem octowym charakte¬ rystyczne niebieskie zabarwienie, które nie wystepuje przy nowym zwiazku. O ile jednak nastapi rozszczepienie tego ostat¬ niego przez kwasy mineralne na goraco, wtedy zjawia sie reakcja na nowo.Zgloszony sposób prowadzi wiec nie¬ spodzianie do nowego zwiazku, o spe¬ cjalnym rodzaju, z nowemi wartosciowe- mi wlasnosciami. PLAccording to the present invention, a new and specific combination of diethylbarbituric acid and dimethylamino-phenyl-dimethylpyrazolone is achieved when the two components are melted together. For this purpose, 462 parts of the compound are melted together. dimethylamino-phenyl-dimethylpyrazolone with 184 parts of diethyl barbituric acid, but the temperature should not exceed 110 °. The clear yellow alloy is treated with water after solidification and cleaned. The resulting compound melts at 95 ° -97 ° and is soluble in hot water, alcohol, ether and other organic solvents. Analysis showed the formula C34H40O5N8. It was calculated that N is 17.34%. 17.34 percent were found. and 17.51 percent The new chemical compound is to be used as a pain reliever, because it strengthens its analgesic, not hypnotic effect. This is important because for the targeted use of the analgetic, especially for the control of headache, care must be taken so that pain can be measured without a hypnotic effect and thus not compromising the ability to work. there is no salt, for example of the type known to be of dialkyl carbitric acids or ar-alkyl-barbiturates with organic bases or salts of phenyl-dimethylpyrazolone or dimethyl-amino-phenyl-dimethylpyrazolone with organic acids or acid amides. These salts are in no way different in color from the parent substances, while in the present invention a compound which is yellow is obtained from the white starting materials. This circumstance already indicates that a molecular change takes place in the described method. The new compound therefore behaves chemically completely different than the salts mentioned. While in the latter the reaction of the separate raw materials is obtained unchanged, this does not occur with the compound referred to. Thus, dimethylamino-phenyl-dimethylpyrazolone gives, with moderate heating with hydrogen peroxide and acetic acid, a characteristic blue color which is not present with the new compound. However, as soon as the latter is split up by the mineral acids while hot, then the reaction is re-started. The requested method thus leads to the expectation of a new compound, of a special kind, with new valuable properties. PL
