Nitro Derivatives of Naturally Occurring β-Asarone and Their Anticancer Activity
نویسندگان
چکیده
β-Asarone (2, 4, 5-trimethoxy-(Z)-1-propenylbenzene) was obtained from Acorus calamus. Nitration of β-asarone with AgNO2/I2 in ether yielded 1-(2, 4, 5-trimethoxy phenyl)-2-nitropropene (1) but with NaNO2/I2 in ethylene glycol obtained 1-(2, 4, 5-trimethoxy phenyl)-1-nitropropene (2). Compound 2 was prepared for the first time and characterized using IR, (1)H-NMR, (13)C-NMR, and GC-MS spectra and it was converted into 1-(2, 4, 5-trimethoxy) phenyl-1-propanone (3) using modified Nef reaction. Based on 1D NOESY experiments, compounds 1 and 2 have been assigned E configuration. Compounds 1 and 2 were subjected to cytotoxic activity using five human cancer cell lines, namely, MCF-7, SW-982, HeLa, PC-3, and IMR-32 by MTT assay. Except in breast cancer line (MCF-7) compound 2 exhibited five- to tenfold increase in activity compared to β-asarone and twofold increase over compound 1.
