Ungeachtet der intensiven Forschung der letzten zwei Jahrzehnte auf dem Gebiet der entzündungshemmenden
Mittel besteht weiterhin Bedarf an einem wirksamen und gut verträglichen Arzneimittel gegen
rhcumatoide Arthritis. Die herkömmlichen, keine Steroide darstellenden, gleichzeitig entzündungshemmend,
analgctisch imduniipyrclisch wirkenden Mittel,
wie Acetylsalicylsäurc, sowie viele neue, im Stadium klinischer Untersuchung stehende Arzneisioffe ermöglichen
lediglich eine symptomatische Milderung des akuten Syndroms, sind jedoch nicht in der Lage,
den Krankheilsverlauf zu ändern. Demgemäß haben die antirheumatischen Wirkungsweisen zweier aller
Heilmittel, nämlich von Gold und D-Pcnicillamin. trotz ihrer potentiellen Nebenwirkungen in den letzten
Jahren neues Interesse gefunden. Die klinische Wirksanikeil
beider Heilmittel wurde an Hand sorgfältiger, an mehreren Stellen durchgeführter klinischer Untersuchungen
neuerlich bestätigt. Mehrere Rheumatologen haben die Auffassung vertreten, daß eine D-penicillaminähnliehc
Verbindung mil überdurchschnittlichen Eigenschaften die Medizin auf diesem bedeutsamen
Gebiet außerordentlich bereichern würde.

oral, lokal, parenteral, mit Hilfe von Inhalalionssprays oder rektal in Form von Einheitsdosen verabfolgen.
»Parenteral« schließt hier subkutane Injektionen, die intravenöse, intramuskuläre und intrasler-

Stufe A
Herstellung von S,S'-Bis-(2,2,8-lrimethyl-
4H-l,3-dioxino[4,5-c]pyridin-5-yl-methyl)-
carbonodithioat
Eine eisgekühlte Lösung von 4,5 g 5-Mercaptomethyl-2,2,8-trimelhyl-4H-l,3-dioxino[4,5-c]pyridin
in 50 ml wasserfreiem Pyridin wird tropfenweise mit 10 ml einer 12,5prozentigen Phosgenlösung in Benzol
versetzt. Man läßt das Reaklionsgemisch sich auf Raumtemperatur erwärmen und rührt 3 Stunden,
wonach man den Ansatz im Vakuum eindampft. Der Rückstand wird einer Extraktion mit Benzol und gesättigter
Natriumbicarbonallösung unterworfen. Die Benzolschicht wird abgetrennt, mit Wasser gewaschen,
über Natriumsulfat getrocknet und im Vakuum eingedampft. Man Chromatographien den erhaltenen
Rückstand an 250 g Kicsclgcl. Die Elution mit Äther
ergibt 3,59 g S,S'-Bis-(2,2,8-lrimcthyl-4H- 1,3-dioxino[4,5 - c]pyridin - 5 - yl - methyl)- earbonodithioal
vom Fp. 88 bis WC.
Stufe B
Herstellung von S,S'-Bis-(3-hydroxy-4-hydroxymcthyl-2-mcthyl-5-pyridylmelhyl)-carboiuidithioal-dihydrochlorid-monohydrat
Eine Lösung von 0,2 g S,S'-Bis-|2,2,8-lrimelhyl-4H- l^-dioxiiio^.S-cJpyridin-S-yl-mclhyll-carbonodilhioat
in 0,9 ml eiskalter konzentrierter Salzsäure wird 5 Minuten kalt gerührt und anschließend mil
2,5 ml Methanol verdünnt. Beim Abkühlen in Eis/ Aceton bildet sich ein kristalliner Niederschlug, den
man abliltricrt. Man erhält 0,12 g S,S'-Bis-(3-hydroxy-4-hydroxymcthyl-2-mclhyl-5-pyridylmethyl)-carbonodithioat-dihydrochlorid-monohydrat
vom Fp. 125 bis 130 C.
