Another study on ilimaquinone and an ilimaquinone analogue (ethylsmenoquinone) showed that these compounds were able to induce G2/M cell cycle arrest and increase apoptosis by caspase-3 cleavage and autophagy; this mechanism was stimulated by both compounds through microtubule-associated protein 1 light chain 3 (LC3) in HCT116 colon cancer cells [184]. Here, CASP3 is linked to malignant colon neoplasm.
