Alpha-Terpineol as Antitumor Candidate in Pre-Clinical Studies.

Background: Alpha-terpineol is monoterpene alcohol with anti-tumor activity against different tumor cell lines (lung, breast, leukemias and colorectal) through blockage of NF-kB expression, which play an important role in tumor cells growth.

Objective: Evaluate the antitumor activity of alpha-terpineol in murine Sarcoma 180 cell line.

Methods: For the tests, different cytotoxic and genotoxic assays were used, including Trypan blue, cytokinesis- blocked micronucleus assay, comet assay, agarose gel DNA fragmentation, flow cytometry and cell viability using fluorescence.

Antiproliferative and Genotoxic Action of an Underexploited Organoteluran Derivative on Sarcoma 180 Cells.

Background: The search for novel metallic chemical compounds with toxicogenic effects has been of great importance for more efficient cancer treatment.

Objective: The study evaluated the cytotoxic, genotoxic and mutagenic activity of organoteluran RF07 in the S-180 cell line.

Methods: The bioassays used were cell viability with 3-(4,5-dimethyl-2-thiazole)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) test, evaluation of apoptosis and necrosis using fluorescence and flow cytometry, cytokinesisblock micronucleus test and comet assay.
