Abstract: Novel glycosides 7-ketosteryl di-O-acyl-pyranoside and 7-.beta.-hydroxycholesteryl 2,3-dideoxy-.alpha.-D-erythro-hex-2-enopyranoside. The glycosides possess valuable pharmacological properties as a medicament. In particular, the cholesterol glycoside in vivo exhibits a selective cell-destructive activity on malignant cells which activity is substantially free of side effects on normal cells. The glycosides possess useful properties, especially pharmacological properties which are the same as the respective unglycosylated aglycon.
