The synthesis and tumor necrosis factor (TNF)-α production enhancing activity of substituted 3'-methyl-thalidomides on human leukemia cell line HL-60 stimulated with 12-O-tetradecanoyl-phorbol 13-acetate (TPA) are described. Though the introduction of an electron-donating amino group at the phthaloyl moiety of α-methylthalidomides enhanced the activity, substituted α-methylthalidomides showed decreased stereoselectivity as compared to that of non-substituted α-methylthalidomide. The data indicates that the TNF-α production enhancing activity of thalidomide derivatives depends on both the electronic-state of substituents at the fused benzene ring and the stereochemistry of the glutarimide moiety.

Es wird über die Synthese der Racemate und der Enantiomere der 3‐Alkyl‐thalidomidanaloga 7a ‐ 7c und des racem. 1,3‐Dimethylthalidomids (8) berichtet. Die absolute Konfigurationder optisch aktiven Syntheseprodukte wird abgeleitet. Die Verbindungen 7a ‐ 7c, 8 und die Synthesezwischenprodukte 6a ‐ 6c sollen tierexperimentell auf ihre sedativ‐hypnotische Wirkung geprüft werden.
