生物活性:
6-Chloromelatonin is a potent melatonin receptor agonist with greater metabolic stability than melatonin. 6-Chloromelatonin compete for [3H]-melatonin and 2-[125I]-iodomelatonin binding to MT1 receptors (pKi=8.9 and 9.1, respectively). 6-Chloromelatonin compete for [3H]-melatonin binding to MT2 receptors (pKi=9.77).

体内研究:
Rats injected with the melatonin agonist, 6-chloromelatonin (0.5 mg/kg) on the day after the phase shift has markedly higher excretion rates of 6-sulphatoxymelatonin compared to those of the controls.

体外研究:
6-Chloromelatonin competes for [3H]-melatonin binding sites in human platelet (Ki=11.4 nM). 6-chloromelatonin (10 pM, 1 nM, 100 nM, 10 μM; 72 hours) inhibits, in a dose-dependent manner, forskolin-stimulated hCG-beta secretion in JEG-3 and BeWo cells but had no effect on basal human chorionic gonadotrophin (hCG-beta) levels.
