Alkylating agents are still nowadays one of the most important classes of cytotoxic drugs, which display a wide range of therapeutic use for the treatment of various cancers. We have synthesized and tested four hybrid homo-azasteroidal alkylating esters for antileukemic activity against five sensitive to alkylating agents human leukemia cell lines in vitro and against P388 murine leukemia in vivo. Comparatively, melphalan and 3-(4-(bis(2-chloroethyl)amino)phenoxy)propanoic acid (POPAM) were also examined. All the homo-aza-steroidal alkylators showed relatively lower acute toxicity, very promising and antileukemic activity both in vitro and in vivo.
Beckmann rearrangement of 3-aza-A-homo-4α-androsten-4,17-dione oxime and 3-oxo-13α-amino-13,17-seco-4-androsten-17-oic 13,17-lactam oxime

Rearragements of 3-aza-A-homo-4α-androsten-4,17-dione oxime produced a mixture of the normal lactam product and the product of a 'second order' cleavage, an unsaturated nitrile. The lactam 3,17α-diaza-A,D-bishomoandrost-4α-ene-4,17-dione was also obtained from the rearrangement of the syn-3-oxo-13α-amino-13,17-seco-4-androsten-17-oic-13,17-lactam oxime. The resolution of syn- and anti-isomers of VIII was effected by column chromatography and their structure was determined by spectral data.
