Octinoxate

Octinoxate (Octyl methoxycinnamate) is a thyroid hormone receptor agonist, reducing the levels of triiodothyronine (T3) and thyroxine (T4) and transcription levels of genes related to type II deiodinase (deio2) in Japanese Medaka. Octinoxate is commonly used as a safe ultraviolet (UV) filter used in the aquatic environment. Octinoxate inhibits CYP1A1 and CYP1B1 to regulate hyaluronan (HA) metabolism in a PI3K pathway-dependent manner in human keratinocytes. Octinoxate also exhibits an anti-estrogenic and anti-androgenic effect in vitro and in vivo[1][2][3][4][5].
