Multiple in vitro tests are widely applied to assess the anticancer activity of new compounds, including their combinations and interactions with other drugs. The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay is one of the most commonly used assays to assess the efficacy and interactions of anticancer agents.

(A) The degree of tetrazolium reduction was determined by MTT assay in primary glioblastoma cells (GBL-13, GBL-15) and glioblastoma cell lines (U87MG, U373MG). Four types of cells were treated with ethanol for 24 h, 48 h, and 72 h. The cell viability was measured by MTT assay.

The viability assay most commonly used throughout the world is the MTT assay, first described by Tim Mosmann in 1983. This colorimetric assay uses reduction of a yellow tetrazolium salt (3-(4,5- di methyl thiazol -2-yl)-2,5-di phenyl tetrazolium bromide, or MTT) to measure cellular metabolic activity as a proxy for cell viability.

The MTT assay has been most widely applied in the assessment of cytotoxic drug therapy. Because implementation of the MTT protocol is technically easier in cell cultures grown in suspension, the assay has been tested for its ability to serve as a predictive tool for selection of chemotherapy for leukemia ( Jiao et al., 1992 ).
