Cabang et al (2017) reported that the anti-proliferative effect of euglenophycin is induced by its ability to put cells in G1 cell cycle arrest. Cell cycle arrest happens when a cell in the cell cycle is checked for errors and a mistake is found. Cells need to duplicate perfectly, if this is not the case the cell cycle is put on hold and the cell does not duplicate. This is to prevent malfunctioning cells from growing in a healthy person.
