A novel series of tetrazole fused benzoxazole derivatives 9a-9j are synthesized, and their structures are characterized by H-1 and C-13 NMR, and mass spectra. The compounds 9a, 9b, 9g, 9h, and 9j demonstrate the highest activity. The compounds 9b and 9g exhibit good anticancer activity, in particular against MCF7, Hop62, and A-549 cell lines with the range of GI(50) values from <0.1 to 4.56 M. Molecular docking study is carried out for the compounds 9a-9j, according to which the compound 9b forms one hydrogen bond with THR766 with the highest docking score (-7.33). This indicates that 9b is effeciently binging to tubulin site.
