Gamma-terpinene, alpha-terpinene, p-cymene, and myrcene are important components of essential oils extracted from many plants and spices. Myrcene, in particular, has potential anticancer activity, leading to cell proliferation arrest, decreased migration, morphological changes, and DNA damage in HeLa cells. Furthermore, myrcene is the only compound among the four that can interact with DNA.
gamma-terpinene, alpha-terpinene, p-cymene, and myrcene are monoterpenes found in many essential oils extracted from a variety of plants and spices. Myrcene also occurs naturally in plants such as hops, cannabis, lemongrass, and verbena and is used as a flavoring agent in food and beverage manufacturing. In this research, the biological efficacy of gamma-terpinene, alpha-terpinene, p-cymene, and myrcene was studied in human cell lines (HeLa, SH-SY5Y, and HDFa). Cytotoxicity, cell proliferation, cell migration, and morphology assays were performed to obtain detailed information on the anticancer properties. Our results show that myrcene has potential biological activity, especially in HeLa cells. In this cell line, it leads to an arrest of proliferation, a decrease in motility and morphological changes with loss of sphericity and thickness, and DNA damage. In addition, the interaction of gamma-terpinene, alpha-terpinene, p-terpinene, and myrcene with calf thymus DNA (ct-DNA) was studied by UV-visible spectrophotometry. DNA binding experiments show that only myrcene can interact with DNA with an apparent dissociation constant (Kd) of 29 x 10-6 M.
