Kojić, Lucie Rárová, Miroslav Strnad, Evgenija A. DjurendićAbstractThis paper describes the synthesis of a new A-homo lactam D-homo lactone androstane derivative from dehydroepiandrosterone. To evaluate the impact of the introduction of nitrogen in the parental scaffold on biological activity, a new androstane enamide-type lactam derivative was prepared and characterized. The new compound as well as starting compounds were screened for cytotoxic, anti-angiogenic and anti-inflammatory activities using several human cancer cell lines (MCF-7, MDA-MB-231, PC3, CEM, G-361, HeLa), endothelial (HUVEC) and non-tumour (MRC-5 and BJ) cell lines. Strong cytotoxic and anti-inflammatory activity with a broad therapeutical window was demonstrated by the A-homo lactam D-homo lactone androstane derivative. The induction of apoptosis in treated PC3 cultures was confirmed using apoptotic morphology screening and a fluorescent double-staining method. New A-homo lactam D-homo lactone androstane derivative induced apoptosis more than the tested reference compounds, Formestane and Doxorubicin. An in silico ADME analysis showed that the compounds possess drug-like properties.Graphical abstract
