| 6-Iodolactone - 6-Iodo-5-Hydroxy-8,11,14-Eicosatrienoic Acid δ-Lactone
Alternative Names: 6-Iodolactone, 6IL, 6-iodo-5-hydroxy-8,11,14-eicosatrienoic acid δ-lactone
Type: Iodolipid / iodinated arachidonic-acid derivative / bioactive lipid metabolite
Formation: 6-IL is formed by iodination of arachidonic acid and has been detected in thyroid and mammary tissues following iodine exposure. Molecular iodine can increase 6-IL formation in tumor tissue containing elevated arachidonic acid.
Function: 6-Iodolactone is a bioactive iodolipid that mediates part of the antiproliferative and apoptotic effects of iodine. It acts as an activator of PPARγ and can regulate proliferation, differentiation, mitochondrial apoptosis, migration, and tumor-associated signaling.
Cancer: Preclinical studies demonstrate inhibition of tumor-cell proliferation and migration and induction of apoptosis. 6-IL activates PPARγ, and inhibition or knockdown of PPARγ substantially reduces its antiproliferative and pro-apoptotic effects. Antitumor activity has been demonstrated particularly in breast, thyroid, and prostate cancer models.
