Um die Reaktionsmöglichkeiten vonN‐Acylharnstoffen mit Aminen eindeutiger zu gestalten, wurden N bzw. N′ blockierte Derivate hergestellt; ihr Spaltungsverhalten wurde in Modellreaktionen untersucht.
为了阐明N-酰基脲与胺类反应的可能性,制备了N和N'封闭衍生物;在模型反应中研究了它们的裂解行为。
Chemical Modification of Fumagillin. I. 6-O-Acyl, 6-O-Sulfonyl, 6-O-Alkyl, and 6-O-(N-Substituted-carbamoyl)fumagillols.
The hydroxy group of fumagillol (3), a degradation product of fumagillin (1), was acylated, sulfonylated, alkylated or carbamoylated, and the anti-angiogenic activity of the resulting products was examined. These compounds inhibited the angiogenesis induced by basic fibroblast growth factor in the rat corneal micropocket assay and the growth of vascular endothelial cells in vitro. Among them, compound 2 (AGM-1470) was found to show the most potent inhibitory effect on the growth of vascular endothelial cells and was selected form this series as a candidate for further development.
1-(N-Acyl-carbamoyl)-2-cyanoaziridines of the formula ##STR1## wherein X is oxygen or sulphur, Z is hydrogen or an organic radical, and Y is a carbonyl, sulphonyl, sulphinyl, sulphenyl, phosphoryl or phosphonyl radical, and salts thereof, exhibit immune-stimulating and cancerostatic activities.
