Abstract

Official abstract text for this publication.

Estrane-based and androstane-based aminosteroid derivatives are described herein. More specifically, the following piperazinyl-steroid compounds of Formula I, Formula II, Formula III, and Formula IV are described. The compounds display cytotoxicity on a variety of cancer cell lines. A process for producing the compounds and their use in the manufacture of pharmaceutical formulations and/or combinations is also disclosed.

The aminosteroid derivative of claim 1 , having the structure: wherein: B is CO, SO, SO 2 , CH 2 , C(X 1 ) 2 , or absent; Y 1 is chosen from OH, halogen, OR 2 , OCOR 3 , OCONR 4 R 5 ; and OSO 2 NR 4 R 5 ; Y 2 is chosen from H, halogen, OH, OR 2 , OMOM (0-methoxymethyl ether), OCOR 3 , OCONR 4 R 5 , OSO 2 NH 2 and OPO(OH) 2 ; Y 3 is H 2 or O; Z is H, halogen or C≡CR 6 ; V is an amino acid, W is CO, SO 2 , CH 2 , CONH, CSNH, or X is chosen from alkyl, alkylsulfinyl, alkylthio, alkylsulfonyl, alkoxy, alkenyl, alkynyl, aryl, alkaryl, alkheterocyclyl, aryloxy, alkoxyalkyl, alkoxyaryl, alkthioalkyl, alkthioaryl, cycloalkyl, heteroaryl, heterocyclyl, heterocyclyloxy and thioalkoxy; X 1 is halogen; R 2 is alkyl; R 3 is H, alkyl or heterocyclyl; R 4 and R 5 are independently chosen from H and alkyl; and R 6 is H or alkyl; or a pharmaceutically acceptable salt, or an N-oxide thereof. 3. The aminosteroid derivative of claim 1 , wherein V is proline and wherein the variables W and X are linked to form the linkage W-X, wherein W-X is chosen from or a pharmaceutically acceptable salt, or an N-oxide thereof. 4. An aminosteroid derivative of having at least one of the following structures: 5. An aminosteroid derivative of Formula II: wherein: A is CHR 1 , NR 1 , O or S; B is CO, SO, SO 2 , CH 2 , C(X 1 ) 2 , or absent; Y 1 is chosen from OH, halogen, OR 2 , OCOR 3 , OCONR 4 R 5 and OSO 2 NR 4 R 5 ; Y 2 is chosen from O and S; Y 3 is H 2 or O; Z is H, halogen or C≡CR 6 ; V is an amino acid, W is CO, SO 2 , CH 2 , CONH, CSNH, or X is chosen from alkyl, alkylsulfinyl, alkylthio, alkylsulfonyl, alkoxy, alkenyl, alkynyl, aryl, alkaryl, alkheterocyclyl, aryloxy, alkoxyalkyl, alkoxyaryl, alkthioalkyl, alkthioaryl, cycloalkyl, heteroaryl, heterocyclyl, heterocyclyloxy and thioalkoxy; X 1 is halogen; R 1 is H or alkyl; R 2 is alkyl; R 3 is H, alkyl or heterocyclyl; R 4 and R 5 are independently chosen from H and alkyl; and R 6 is H or alkyl; or a pharmaceutically acceptable salt, or an N-oxide thereof. 6.
