Description

Stwierdzono, ze organiczne zwiazki rte¬ ciowe, które zawieraja grupy kwasne, a w których rtec nie tworzy polaczenia o cha¬ rakterze soli, daja sie latwo przeprowadzic w zasadowe sole bizmutowe. Zwiazki te o- trzymuje sie zapomoca wymiany rozpu¬ szczalnej soli zwiazków rteciowych z nor¬ malnemu lub zlozonemi solami bizmutowe¬ mu Otrzymane w ten sposób preparaty na¬ daja sie bardzo dobrze do leczenia, np. sy¬ filisu.W przeciwstawieniu do znanych z pa¬ tentu niemieckiego Nr 414191 soli rtecio¬ wych zlozonych kwasów bizmutylowych, o- trzymane wedlug niniejszego sposobu pre¬ paraty wykazuja slabsze wlasnosci truja¬ ce, przy conajmniej takim samym skutku leczniczym. W znanych preparatach rtec jest zwiazana w postaci jonu, podczas gdy w preparatach otrzymanych w mysl wyna¬ lazku jest ona zwiazana organicznie, two¬ rzac polaczenie zlozone, co pociaga za so¬ ba oslabienie dzialania trujacego.Przyklad I. 52,3 g sodowej soli kwa¬ su rteciowosalicylo-alliloamido-o-octowego, otrzymanego wedlug przykladu IV paten¬ tu niemieckiego Nr 423031, rozpuszcza sie w; 150 cm3 wody. Mieszajac energicznie, dodaje sie kroplami roztwór, zawierajacy 48,5 g azotanu bizmutowego, 48,5 g glice¬ ryny i 97 cm3 wody, a nastepnie mieszani¬ ne reakcyjna zobojetnia sie, dodajac 2-n lugu sodowego. Powstala biala zasadowa sól bizmutowa kwasu rteciowo-salicylo-alliloamido-o-octowego odsacza sie, prze¬ mywa wodalvalkdiolemi eterem i suszy w prozni. * -* * * Przyklad IL W ten sam sposób, jak wskazano w przykladzie I, otrzymuje sie zasadowa sól bizmutowa kwasu 4-rteciowo- allilooksy-3-acetyloaminoibenzeno - 1 - arsi- nowego, dzialajac roztworem 48,5 g azota¬ nu bizmutowego na 60 g soli sodowej kwa¬ su 4-rteciowo-allilooksy-3-acetylo-amino- benzeno-i-arsinowego, rozpuszczonego w 180 cm3 wody.Kwas allilo-oksy-acetyloaminobenzeno- arsinowy otrzymuje sie, dzialajac w alka¬ licznym roztworze bromkiem allilowym na kwas 3-acetyloamino-4-oksy-benzeno-7 -ar- sinowy. Kwas ten rozpuszcza sie dobrze w alkoholu metylowym i krystalizuje z wody w postaci bialych igielek. Wprowadzanie rteci odbywa sie tym samym sposobem, jak to produkcie wyjsciowym, wymienionym W przykladzie L PL PLIt has been found that organic mercury compounds containing acidic groups, in which mercury does not form a salt bond, can be easily converted into basic bismuth salts. These compounds are obtained by exchanging a soluble salt of mercury compounds with normal or complex bismuth salts. Preparations obtained in this way are very suitable for the treatment of, for example, syphilis. In contrast to the mercury salts of complex bismuth acids known from German patent No. 414191, the preparations obtained according to the present method have weaker toxic properties, while at least having the same therapeutic effect. In known preparations, mercury is bound as an ion, whereas in the preparations obtained according to the invention, it is bound organically, forming a complex compound, which results in a weakening of the toxic effect. Example 1. 52.3 g of the sodium salt of mercuric salicyl-allylamide-o-acetic acid, obtained according to Example IV of German Patent No. 423031, is dissolved in 150 cm³ of water. While stirring vigorously, a solution containing 48.5 g of bismuth nitrate, 48.5 g of glycerol and 97 cm³ of water is added dropwise, and then the reaction mixture is neutralized by adding 2 N sodium hydroxide solution. The resulting white basic bismuth mercuric-salicyl-allylamide-acetic acid salt is filtered off, washed with water, alkali metal hydroxide, and ether, and dried in vacuo. * -* * * Example IL In the same manner as indicated in Example I, the basic bismuth salt of 4-mercury-allyloxy-3-acetylaminoibenzene - 1 - arsinic acid is obtained by treating with a solution of 48.5 g of bismuth nitrate per 60 g of the sodium salt of the acid 4-mercury-allyloxy-3-acetyl-amino-benzene-i-arsinic acid, dissolved in 180 cm3 of water. Allyl-oxy-acetylaminobenzene-arsinic acid is obtained by reacting 3-acetylamino-4-oxy-benzene-7-arsinic acid in an alkaline solution with allyl bromide. This acid dissolves well in methyl alcohol and crystallizes from water in the form of white needles. The introduction of mercury is carried out in the same way as for the starting product mentioned in the example L PL PL
