Abstract: The present invention relates to the biology and mechanism of action of the naturally occurring compound Narciclasine, especially as an anti-cancer agent for brain tumors. The invention provides new insights on the target molecule of Amaryllidaceae isocarbostyril derivatives as for example Narciclasine and provides new prodrugs of these Amaryllidceae isocabostyril constituents for treating cancer, specifically cancers or tumors located in the brain.

Abstract: Isocarbostyril alkaloid derivatives having an anti-proliferative and anti-migratory activities are disclosed. In particular, compounds of formula (I) or (II), as well as stereoisomers, tautomers, racemates, prodrugs, metabolites thereof, pharmaceutically acceptable salt and/or solvate are encompassed which are useful in the treatment and prophylaxis of cancer. Methods of preparation are also disclosed.

Abstract: Glycosylated steroid compounds having anti-migratory activity and methods for their preparation are disclosed. Pharmaceutical compositions having an effective amount of the glycosylated steroid compounds are also disclosed. The glycosylated steroid compounds may be used as a medicament. Preparation of medicaments containing the glycosylated steroid compounds for treatment of diseases associated with cell migration, in particular, cancer, are disclosed. The glycosylated steroid compounds or pharmaceutical compositions containing the glycosylated steroid compounds may be used in the treatment of diseases associated with cell migration, in particular for the treatment of cancer.

Abstract: The present invention relates to novel steroid compounds of Formula (IB) having anti-tumor activity. The present invention also relates to a method for the preparation of said steroid compounds. The invention further relates to a pharmaceutical composition comprising an effective amount of said steroid compounds. Furthermore, the present invention concerns the use of said steroid compounds as a medicament and in the preparation of a medicament for the treatment of cancer. The present invention also relates to the use of a steroid compound or a pharmaceutical composition comprising said steroid compound according to the invention in the treatment of cancer.
