A hybrid pharmacophore approach was applied to design and synthesize a series of benzo[b]thiophene-diaryl urea derivatives 17a–g with potential anticancer effect. In vitro antiproliferative activities of all target compounds were evaluated against HT-29 and A549 cancer cell lines. Three compounds 17b, 17d, and 17f exhibited antiproliferative activities on both cell lines comparable to that of the positive
