A novel series of thiazolo[2,3-b]quinazoline (16-19, 25-28, and 34-37) and cyclohepta[d]thiazolo[3,2-a]pyrimidine (20-23, 29-32, and 38-41) analogs was designed and synthesized. Structure elucidation of the synthesized compounds was attained by the use of H1 NMR, C13 NMR, and mass spectrometry. The obtained compounds were evaluated for their in vitro antitumor activity using the National Cancer Institute's 60 cell lines' panel assay that included nine tumor subpanels, namely, leukemia, non-small cell lung, colon, CNS, melanoma, ovarian, renal, prostate, and breast cancer cells. Most of the investigated compounds showed a remarkable broad-spectrum antitumor activity. Compounds 19, 28, 32, and 34 proved to be 10-, 15-, 2-, and 7-fold more active than 5-FU, with GI50 MG-MID values of 2.4, 1.5, 11.2, and 3.1 μM, respectively.
