Anticancer activities of some newly synthesized pyridine, pyrane, and pyrimidine derivatives Original Research Article

A series of pyridine, pyrane, and pyrimidine derivatives (2–11) were newly synthesized using nitrobenzosuberone 1 as a starting material. The antitumor activities of the synthesized compounds were evaluated utilizing 59 different human tumor cell lines, representing leukemia, melanoma, lung, colon, brain, ovary, breast, prostate as well as kidney. Some of the tested compounds especially 2, 3, 4c, 6, 7, 9b, 10a, and 11 exhibited better in vitro antitumor activities at low concentration (log10 GI50 = −4.7) against the used human tumor cell lines. Additionally, compounds 3, 4c, 6, 7, and 9b were highly selective to inhibit leukemia cell lines. The detailed synthesis, spectroscopic data and antitumor properties for the synthesized compounds were reported.
