Synthesis and antiproliferative activity of eight new derivatives of betulinicacid (1) and betulin (2) are described. The compounds were tested against fifteen tumor cell lines. The toxicity against normal human fibroblasts and the mode of cell death on lung cancer cell line induced by the most active compounds 9 (bis(ethylcarbamate)betulin) and 11 (3-O-ethylcarbamate of 28-O-acetylbetulin) was investigated
