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.

Potent inhibition of Janus kinase 3 was found for a series of naphthyl(beta-aminoethyl)ketones (e.g. 7, pIC50 = 7.1+/-0.3). Further studies indicated that these compounds fragment in less than 1 h by retro-Michael reaction in the Jak3 in vitro ELISA assay procedure. The breakdown product of 7, 2-naphthylvinyl ketone (22, pIC50 = 6.8+/-0.3) showed very similar inhibitory activity to 7. Compounds 7 (in
