Different kinds of drugs are developed and used to improve cancer therapy. Some evidence has shown that nonsteroidal anti-inflammatory drugs (NSAIDs) have anticancer activity in addition to anti-inflammatory effects. To improve the safety profile of NSAIDs and enhance anticancer potency, different strategies such as hybridization are used in several studies. Indomethacin is a lead compound in NSAIDs classes' demonstrated inhibitory activity for some malignancies including breast and ovarian cancer. Two kinds of hybrids were proposed and synthesized using diamine linkers via amid bonds: indomethacin-indomethacin (hybrid A) and indomethacin-methotrexate (MTX; hybrid B). To confirm the structures of newly synthesized hybrids, melting points, IR, H NMR were applied. The cytotoxic effects of synthesized hybrids against Hela and MCF-7 cancer cells were evaluated by MTT assay. The results showed that both hybrids were more cytotoxic than indomethacin and MTX alone.
