α-Alkyl-thyroxine und Verfahren zu ihrer Herstellung.α-alkyl-thyroxine and process for their preparation.
Sei der weiteren Bearbeitung der dem Hauptpatent 44 93 533 zu Grunde liegenden Aufgabe wurde festgestellt, daB man Verbindungen der allgemeinen Formel worin R1 für eine der Gruppen Äthyl, Propyl, butyl oder Pentyl steht und R2 eine aminogruppe oder eine Acylaminogruppe bedeutet, sowie gegebenenfalls walze dieser Verbindungen mit anorganischen oder organischen Basen oder Sauren herstellen kann, indem man einen aktivierten Ester, vorzugsweise den p-osylester, einer Verbindung der allgemeinen Formel worin A1 dieselbe Bedeutung wie in Formel I hat, mit einer Verbindung der allgemeinen Formel worin R2 für einen Alkylrest steht, in Gegenwart eines Lösungsmittels und/oder einer anorganischen oder organischen Base, vorzugsweise Pyridin, gegebenenfalls bei erhöhter Temperatur zur Reaktion bringt, die resultierende Verbindung der allgemeinen Formel worin R1 und R2 dieselbe Bedeutung wie in den vorherigen Formeln haben, nach an sich bekannten Methoden wie Reduktion, Diazotierung und Sandmeyer-Reaktion in eine Verbindung der allgemeinen Formel worin R1 und R2 dieselbe Bedeutung wie in den vorherigen Formeln haben überführt, nach entfernung des Lösungsmittels, gegebenenfalls ohne vorherige Reinigung, mit sauren Verseifungsmitteln, vorzugsweise Bromwasserstoffsäure/Eisessig oder Jodwasserstoffsäure/ Eisessig zu einer Verbindung der allgemeinen Formel worin R1 die gleiche Bedeutung wie oben hat, hydrolysiert, diese Verbindung durch gelindes erwärmen mit wassrig-alkalischen Lösungen oder mit wässrigen Lösungen von Mineralsäuren in das entsprechende 3,5-Dijod-αalkylthyronin umwandelt und das ifydrolysat vorzugsweise in alkalischen Medium mit Jod oder anderen jodierend wirkenden Agenzien zunentsprechenden α-alkylkthyroxin kodiert und die erhaltene Verbindung gegebenenfalls an der Aminogruppe acyliert' und die so erhaltene Verbindung der allgemeinen Formel nach Anspruch 1 gegebenenfalls mit anorganischen oder organischen Basen oder sauren in die entsprechenden salze überführt. los sind schon lange Versuche bekannt, die Arteriosklerose und vor allem die Coronarsklerose durch Verwendung von Schilddrüsenhormonen günstig zu beeinflussen. Experimentell ist eine solch günstige Beeinflussung durch eine senkung des Cholesterinspiegels im Serum nachweisbar. Als unerwünschte Nebenwirkung tritt jedoch bei der Verabreichung von Schilddrüsenwirkstoffen eine Erhöhung des Grundumsatzes auf, die eine hnwendung zumindest bei Coronarsklerosen verbietet. Es wird z.B. der Grundumsatz bei männlichen Ratten, gemessen an der Zunahme des Sauerstoffverbrauches, durch subcutane Applikation von 0,06 mg L-Thyroxin/kg Ratte um 41 + 5,2 06, durch subcutane Applikation von 0,3 mg L-Thyroxin/kg Ratte sogar um 70 + 6 erhöht. Die Verbindungen der Formel I haben nun den Vorzug, den Serumcholesterinspieges wesentlich zu senken, ohne den Grundumsatz zu erhöhen. Gibt man z. B. Ratten, die mit einer cholesterinreichen Diät ernährt wurden, über 14 Tage täglich 30 g ol/kg Ratte DL-α-Äthylthyroxin-Natrium subcutan, so sinkt der Serumcholesterinspiegel der behandelten Tiere um 37 %, durch tägliche Applikation von 30 g ol/kg Ratte DI-a-Pentylthyroxin-Natrium um 15 °ß. Bestimmt man den Grundumsatz bei Ratten, so ergibt die subcutane Applikation der genannten Verbindungen der allgemeinen Formel I in der erwähnten Konzentrat ion keine Erhöhung des Sauerstoffverbrauchs. Die antigoitrogene Wirkung, das ist die Aufhebung der durch Thiouracil hervorgerufenen Vergrößerung der Schilddrüse bei der Ratte, kann als weiteres Maß für die unerwünschte thyreomimetische Wirkung einer Verbindung herangezogen werden. Dabei entsprechen 20 mg dl-α-Äthylthroxin in ihrer Wirkung 0,020 mg L-Thyroxin. Eine Verminderung der Gewichtszunahme, wie sie bei der Verabreichung von Schilddrüsenhormonen als Ausdruck der thyreotoxischen Wirkung dieser Verbindungen auftritt, ist bei der Verbindung der allgemeinen Formel I nicht beobachtet worden. So entspricht z. B. das Endgewicht der mit 4,0 mg/kg Ratte a-Äthyl-thyroxin über einen Zeitraum von 14 Tagen behandelten Ratten dem der Diätkontrollen, Die Verbindungen der allgemeinen Formel I enthalten ein asymmetrisches Kohlenstoffatom und können daher in zwei optisch aktiven Formen auftreten. Die vorstehenden Angaben beziehen sich auf das Isomerengemisch Die Auftrennung in die d- und l-i'orm kann nach an sich bekannten Methoden erfolgen. Außerdem kann man bei der nachstehend beschriebenen erfindungsgemäßen Herstellung der Verbindungen der allgemeinen Formel I von optisch aktiven Ausgangsprodukten ausgehen und dadurch zu optisch aktiven a-Alkyl-thyroxinen gelangen.In the further processing of the problem on which the main patent 44 93 533 is based, it was found that compounds of the general formula where R1 stands for one of the groups ethyl, propyl, butyl or pentyl and R2 stands for an amino group or an acylamino group, as well as optionally rolling these compounds with inorganic or organic bases or acids can be produced by an activated ester, preferably the p-osyl ester, a compound of the general formula wherein A1 has the same meaning as in formula I, with a compound of the general formula in which R2 stands for an alkyl radical, in the presence of a solvent and / or an inorganic or organic base, preferably pyridine, reacts, if appropriate at an elevated temperature, the resulting compound of the general formula where R1 and R2 have the same meaning as in the previous formulas, according to methods known per se such as reduction, diazotization and Sandmeyer reaction into a compound of the general formula where R1 and R2 have the same meaning as in the previous formulas, after removal of the solvent, optionally without prior purification, with acidic saponifying agents, preferably hydrobromic acid / glacial acetic acid or hydroiodic acid / glacial acetic acid, to a compound of the general formula where R1 has the same meaning as above, hydrolyzed, this compound is converted into the corresponding 3,5-diiodo-αalkylthyronine by gentle heating with aqueous-alkaline solutions or with aqueous solutions of mineral acids and the hydrolyzate is preferably iodinated in an alkaline medium with iodine or other iodine active agents encoded to the corresponding α-alkylkthyroxine and the compound obtained is optionally acylated on the amino group and the compound of the general formula according to claim 1 thus obtained is converted into the corresponding salts with inorganic or organic bases or acids. Attempts have long been known to favorably influence arteriosclerosis and especially coronary sclerosis by using thyroid hormones. Such a favorable influence can be demonstrated experimentally by lowering the cholesterol level in the serum. However, an undesirable side effect of the administration of active thyroid substances is an increase in the basal metabolic rate, which prohibits its use, at least in the case of coronary sclerosis. For example, the basal metabolic rate in male rats, measured by the increase in oxygen consumption, by subcutaneous application of 0.06 mg L-thyroxine / kg rat by 41 + 5.2 06, by subcutaneous application of 0.3 mg L-thyroxine / kg rat even increased by 70 + 6. The compounds of the formula I now have the advantage of substantially lowering the serum cholesterol level without increasing the basal metabolic rate. Are you z. B. Rats fed a cholesterol-rich diet, daily 30 g ol / kg rat DL-α-ethylthyroxine sodium subcutaneously for 14 days, the serum cholesterol level of the treated animals falls by 37%, by daily application of 30 g ol / kg of rat DI-a-pentylthyroxine sodium by 15 ° ß. If the basal metabolic rate is determined in rats, the subcutaneous administration of the compounds of general formula I mentioned in the concentration mentioned does not result in an increase in oxygen consumption. The antigoitrogenic effect, that is, the abolition of the thiouracil-induced enlargement of the thyroid gland in the rat, can be used as a further measure of the undesired thyreomimetic effect of a compound. The effect of 20 mg dl-α-ethylthroxine is equivalent to 0.020 mg L-thyroxine. A reduction in weight gain, as occurs when thyroid hormones are administered as an expression of the thyrotoxic effect of these compounds, has not been observed in the case of the compound of the general formula I. So z. B. the final weight of the rats treated with 4.0 mg / kg rat α-ethyl-thyroxine over a period of 14 days that of the diet controls. The compounds of general formula I contain an asymmetric carbon atom and can therefore occur in two optically active forms. The above information relates to the mixture of isomers. The separation into the d- and l-i'orm can be carried out by methods known per se. In addition, in the preparation according to the invention of the compounds of the general formula I, which is described below, one can start from optically active starting materials and thereby arrive at optically active α-alkyl-thyroxines.
