NS-3 (montirelin, CG 3703) is an analog of thyrotrophin releasing hormone (TRH). More potent and longer acting than TRH, CG-3703 produced beneficial effects in animal models of concussion-induced unconsciousness, cerebral ischemia, memory disruption, spontaneous convulsions in rats, narcolepsy, and spinal trauma. Given its efficacy in these models, the potential indications were broadened to include seizures, nerve trauma, cognitive dysfunction, and sleep apnea.

CNS Activity

Curator's Comment: NS-3 (montirelin hydrate, CG 3703) can readily penetrate into the rodent brain. Centrally active TRH analogue CG3703 can improve neurological outcome and survival after brain injury in rats, perhaps through direct effects on cerebral metabolism. No available data on human.

Curator's Comment: There are some evidences of Motirelin effectitivity on animal models: 1) two-week oral administration of CG-3703 (16 mg/kg) significantly reduced cataplexy and daytime sleep in canine narcolepsy http://www.ncbi.nlm.nih.gov/pubmed/10869884,9236248 2) Chronic intake of CNK-602A (NS-3, montirelin, CG 3703) in a dose that does not affect plasma levels of T3 and T4 inhibits tonic convulsions in Spontaneously epileptic rats and suggest that this drug may be an effective treatment for convulsive seizures in patients with epilepsy. http://www.ncbi.nlm.nih.gov/pubmed/8603636
0.5 mg of montirelin administered over 14 days improved ratings of global clinical state in 73% of patients exhibiting “disturbances of consciousness”.
Route of Administration: Unknown

Curator's Comment: Among other TRH analogs montirelin (CG-3703) at concentrations 0.1-50 μM attenuated cell damage in retinoic acid differentiated SH-SY5Y cells
NS-3 (montirelin, CG 3703) is cytoprotective at 0.1-50 μM
