Background: Malignant mesothelioma is a highly aggressive and fatal cancer of older people. Consistently associated with asbestos exposure, mesothelioma is diagnosed when it is extensively metastasized and it has a dismal prognosis.

Benzofuwran derivatives found in several natural compounds and synthesized for various purposes. Due to their molecular structure’s electron behaviors they have several biological activities such as antitumor, cytotoxic, anticancer, antimicrobial, antifungal, ant proliferative etc. We synthesized (3-methyl-benzofuran-2-yl) ketoxime derivatives (one of them are new compound) and structure elucidation of the compounds was performed using IR, 1H-NMR, MASS spectroscopy and elemental analysis. X-Ray analysis of H2 compound was elucidated for the first time with this study in the literature. Cytotoxic activity against F2408 and HepG2 cell lines was also evaluated for the first time by MTT and NR uptake methods. Anti-microbial activity of H1, H2 and H3 was also investigated with broth micro dilution test. The results show that these ketoximes have cytotoxic and anti-microbial activity on different higher doses.

Cancer is the one of most leading cause of death and fast growing disease with increase its global burden due to cancer causing behavior particularly smoking, drinking alcohol coal mining worker, consumption of non-organic foods, uses of non-food grad utensils and uses of food additives. About 13.5 million case of cancer have been reported worldwide in which 7.8 million deaths occur. Out of 7.8 million mortality rate 73% death cases have been reported in poor or middle socio-economic countries. Where population are unaware, poor sanitation and lack of hygiene. Cancer is the most sever and life threatening disease which cause millions of death worldwide.
