Antiproliferative activity of twenty one Michael adducts of aroylacrylic acids and cyclic amines (
N
-Me-piperazine, imidazole, 2-Me-imidazole, and indole) was tested toward five human tumor cell lines (HeLa, LS174, K562, FemX, MDA-MB-361) in vitro. Compounds exerted antiproliferative activity in the high to the single-digit micromolar concentrations, causing increase of the cell population fraction in S phase and apoptosis.
N
-Me-piperazine and imidazole derivatives of aroylacrylic acids substituted with bulky alkyl substituents (2,4-di-
i
-Pr-Ph-, 2,4,6-tri-Et-Ph-, or
β
-tetrahydronaphthyl-) showed the best potency, while indole adducts were proved as the inferior antiproliferative agents. Few compounds showed significant selectivity, tumor versus healthy cells, with selectivity index

for the most selective congener. An unbiased in silico distinction between more and less potent compounds was obtained from 3D QSAR models derived by alignment-independent GRIND-2 descriptors.
