The invention relates to derivatives of glycopeptide and lipoglycopeptide antibiotics possessing an altered ionization state with respect to the parent glycopeptide or lipoglycopeptide antibiotic, and having the ability to be regenerated as the parent glycopeptide or lipoglycopeptide antibiotic under physiological conditions. These compounds are useful as antibiotics for the prevention and/or the treatment of bacterial infections.
The present invention relates to novel substituted indolo[2,3-a]quinolizines and stereoisomeric forms thereof and/or pharmaceutically acceptable salts of these compounds as well as pharmaceutical compositions containing at least one of these substituted indolo[2,3-a]quinolizines together with pharmaceutically acceptable carrier, excipient and/or diluents. Said novel substituted indolo[2,3-a]quinolizines have been identified as useful for the prophylaxis and treatment of cancer by the induction of strong mitotic delays, chromosomal misalignments and mitotic tri- and multipolarization leading to cell cycle stop and apoptosis. Furthermore a synthesis for preparation of the substituted indolo[2,3-a]quinolizines is disclosed in the present invention.
