Zusammenfassung Zur Untersuchung möglicher Struktur-Wirkungs-Beziehungen in der Reihe der verbrückten Thalidomid-Analoga wurden 36 offenkettige und verkürzte Abkömmlinge der Testsubstanz K 2004 (2) synthetisiert. Die pharmakologische Untersuchung der hergestellten Verbindungen ergab in keinem Falle eine signifikante sedative Aktivität. Dies legt den Schluß nahe, daß die intakte Glutarimid-Struktur bei1 und2 für das Zustandekommen der schlafinduzierenden Wirkung unentbehrlich ist.

Thalidomide analogues
For the evaluation of possible structure-activity relationships in the series of bridged thalidomide analogues 36 openchain and shortended congeners of the test substance K 2004 (2) have been synthesized. The pharmacological evaluation of these compounds revealed in no case any significant sedative activity. This leads to the conclusion that the intact glutarimide structure must be essential for the sleep-inducing activity of1 and2.

A commercial sample of supposedly 3-methyl-3-butenenitrile was separated by gas chromatography into two components. Analysis of the i.r. and NMR spectra of these two components showed that the original mixture contained 25% 3-methyl-3-butenenitrile and 75% 3-methyl-2-butenenitrile, and that an i.r. spectrum recently reported in this journal [1] for 3-methyl-3-butenenitrile was actually that of 3-methyl-2-butenenitrile. Thus, the spectral data reported for 3-methyl-3-butenenitrile [1] and the resulting conclusions regarding the nature of the conformational equilibrium in this molecule should be disregarded. 相似文献

The acid-catalyzed condensation of quinisatines 5a-c or their aminals 4a-c with phenols 6a-i led to a number of 3-hydroxy-3-hydroxyphenyl-2,4-dioxo-1,2,3,4-tetrahydroquinolines 7a-s which were considered as potential antiinflammatory agents. 相似文献
