In this continuation of our research on derivatives containing the stilbene privileged structure or that are derived from it, we report the results of further studies carried out on the previously initiated collection of compounds. We used a parallel synthetic approach to rapidly obtain small sets of compounds and started the annotation of the library in progress by calculating some physicochemical properties to be eventually correlated with biological activities. A pharmacophore for the antiproliferative activity was also built to summarize the features of the library. We evaluated the antiproliferative and pro-apoptotic activities of all compounds as well as the cell-cycle effects of some representative compounds. After in-depth investigations, 3'-phenyl- [1, 1';4', 1"]terphenyl-4,3",5"-triol showed the most interesting biological profile, as it interferes with cell-cycle progression at the G(1) -> S transition, acting on retinoblastoma phosphorylation and inducing cell differentiation.
