represents a steroid residue, the use of compounds of the general formula (I) in medicine and for the prophylaxis and/or the treatment of infectious diseases. Furthermore described are pharmaceutical compositions containing at least one compound of the general formula (I). A further aspect of the invention relates to the synthesis of said compounds of the general formula (I).
Synthesis of novel 17-(5′-iodo)triazolyl-3-methoxyestrane epimers via Cu(I)-catalyzed azide–alkyne cycloadditon, and an evaluation of their cytotoxic activity in vitro
regioselective Cu(I)-catalyzed 1,3-dipolar cycloaddition of 3-methoxyestrane 17α- and 17β-azide epimers (3 and 5) with different terminalalkynes afforded novel 1,4-substituted triazolyl derivatives (8a-f and 11a-f). If the Ph3P in the classical CuAAC process was replaced by Et3N, the formation of small quantities of 5-iodotriazoles (9a-f and 11a-f) was observed. For the preparation of 5-iodo-1,2,3-triazoles (9a-f
