Application

1. Hormone postulated to mediate photoperiodicity in mammals. Inhibits cerebellar nitric oxide synthetase

2. Melatonine can be used in sleep induction, modifies circadian rhythm, antioxidant, free radical scavenger

3. Immunostimulant;Melatonin receptor ligand

4. Melatonin has complex effects on apoptotic pathways, inhibiting apoptosis in immune cells and neurons but enhancing apoptotic cell death of cancer cells. Inhibits proliferation/metastasis of breast cancer cells by inhibiting estrogen receptor action.
