A series of 14 N-acyl-hydrazones L-serine derivatives have been synthesized and evaluated for their in vitro antitumoral activities against four neoplastic cancer cells: HL-60 (leukemia), MDA-MB-435 (melanoma), HCT-8 (colon) and SF-295 (nervous system). Five compounds (3g, 3h, 3i, 3k and 3n) were considered active against at least two cancer cell lines, with more than 90% of growth inhibition. Compound 3h, with IC50 of 2.04 μg/mL, seems to be moderately selective to HCT-8 and can be considered in further studies aiming new prototypes for a lead molecule against colon cancer.
