Abstract
El cancer representa un grupo de enfermedades caracterizadas por la proliferación celular anormal, actualmente se trata de un problema de salud importante. Es en este sentido que los derivados de productos naturales son una importante fuente de investigación como posibles tratamientos. En la presente investigacion, la capacidad antiproliferativa, el daño en el ADN y los efectos apoptóticos de tres lactonas sesquiterpenicas (damsin, coronopilina y santamarina) se analizaron en las siguientes lineas celulares de cancer: A549 (cancer de pulmón de celulas no pequeñas), HeLa (cancer de cuello uterino) y Pane 1 (cancer de pancreas). En la línea celular A549, todas las moleculas mostraron un efecto antiproliferativo en cada concentración sin presentar daflo en el ADN, la santamarina y la coronopilina aumentaron la cantidad de células apoptoticas a altas concentraciones. Damsina y santamarina mostraron un efecto antiproliferativo sobre las celulas HeLa en todas las concentraciones, pero la coronopilina solo a dosis elevadas, de forma similar, se observo daflo al ADN y efecto apoptotico para la coronopilina y la santamarina. Para la lihea celular Panc-1, damsina y santamarina mostraron un efecto antiproliferativo, se observo daflo en el ADN a altas concentraciones de las tres moleculas, sin efecto sobre la induction de la apoptosis.
Cancer represents a group of diseases characterized by abnormal cell proliferation, currently represents major health problem. It is in this sense that derivatives of natural products are an important source of investigation as possible treatments. In the present research antiproliferative capacity, DNA damage and apoptotic effects of three sesquiterpene lactones (damsin, coronopilin and santamarin) were assayed in the following cancer cell lines: A549 (non-small cell lung cancer), HeLa (cervical cancer) and Panc-1 (pancreatic cancer). In A549 cell line all molecules showed antiproliferative effect at every concentration without presenting DNA damage, santamarin and coronopilin increased the amount of apoptotic cells at high concentrations. Damsin and santamarin showed antiproliferative effect on HeLa cells at all concentration but coronopilin only at high, similarly DNA damage and apoptotic effect was observed for coronopilin and santamarin. For Panc-1 cell line, damsin and santamarin showed antiproliferative effect, DNA damage was observed at high concentrations of the three molecules, without effect on apoptosis induction.
