Nobiletin is a flavanoid isolatable from citrus peels. It has demonstrated anti-cancer properties in several in vitro cell models and garnered interest as a potential treatment for the motor and cognitive symptoms of Parkinson's disease. However, investigation of this compound has not moved beyond animal studies.

Curator's Comment: referenced study was conducted in mice
In a mouse model of Parkinson's disease mice were induced to motor and cognitive deficits by dosing with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Intraperitoneal administration of 50 mg/kg of Nobiletin for 2 consecutive weeks improved motor and cognitive deficits and continued to improve for 2 weeks after withdrawal. However, nobiletin did not block loss of dopaminergic neurons seen in the MPTP-treated mouse midbrain, nor did it rescue decreased tyrosine hydroxylase (TH) protein levels seen in the striatum or hippocampal CA1 region of these mice.
Route of Administration: Intraperitoneal
Human leukemia HL-60 cells were maintained in RPMI-1640 medium supplemented with 10% fetal bovine serum, 2 mM glutamine and 1% penicillin/streptomycin. Cell line was maintained at 37 deg-C and 5% CO2 atmosphere. HL60 cells were placed into 12-well plates at a density of 2 x 10^5 cells per well. Cultures were incubated overnight and then treated with different concentrations of nobiletin for 24 hours. At the end of incubation, cells were harvested and counted in a hemocytometer. Nobiletin was found to have an IC50 of 41.5 micro-M and AC50 above 100 micro-M.
