Azasteroids as antifungals

Steroids, 2003
Azasteroids and derivatives thereof with antifungal potential are reviewed. Special emphasis is put on steroids with nitrogen as part of the steroidal framework, natural substances, and lines of development emerging from them.

Recent advances in azasteroids chemistry.

Steroids, 2008
Modified steroids have attracted a great deal of attention these last years. Their preparation is a stimulating challenge to the organic chemist, often demanding development of new and generally useful reactions. Moreover, the biological properties of modified steroids have proved to be of interest.

N-Alkylation of 17-azasteroids

Steroids, 1994
N-Alkylation of 17-azasteroid lactams (16-oxo-17-azaandrost-5-en-3 beta-ol acetate 3 and its D-homo analog 4) was studied. It has been found that both lactams are readily alkylated with iodomethane or iodoethane. In contrast to this there was no reaction with 2-iodo-6-methylheptane due to the steric hindrance.

Phosphorescence of 8-azasteroids and related compounds

Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2005
We have investigated the electron absorption, fluorescence and phosphorescence spectra of 8-azasteroids and model compounds containing enaminodicarbonyl fragment. It has been shown that the investigated compounds have absorption and phosphorescence spectra similar in form and position.
