(3-Amino-6-thiophen-2-yl-thieno[2,3-b]pyridin-2-yl)phenylmethanone (3) was discovered as a new type of cytotoxic agent selective against a tumorigenic cell line. The molecular structure of a previously reported compound, (4-hydroxy-3-methyl-6-phenylbenzofuran-2-yl)phenylmethanone (2), had remarkably similar bioisosteric substructures to that of compound 3. Although the relationship between the molecular structure and biological activity of each derivative synthesized from these two hit compounds (2 and 3) were studied, unexpectedly no correlation was observed. However, after further synthetic study from 3, one of the most potent derivative (10k) having a different SAR profile from 2, was discovered.
