Norquetiapine dihydrochloride  (Synonyms: N-Desalkylquetiapine dihydrochloride)

Norquetiapine ( N-Desalkylauetiapine) dihydrochloride, a metabolite of Quetiapine (HY-14544), is a selective HCN1 channel inhibitor, with an IC₅₀ of 13.9 μM. Norquetiapine dihydrochloride selectively inhibits noradrenaline reuptake, is a partial 5-HT_1A (K_i = 45 nM) receptor agonist, and acts as an antagonist at presynapticα2 (K_i = 237 nM), 5-HT_2C(K_i = 107 nM), and 5-HT₇ (K_i = 76 nM) receptors. Norquetiapine dihydrochloride blocks the human cardiac sodium channel Nav1.5 in a state-dependent manner. Norquetiapine dihydrochloride shows partial anti-inflammatory effects in LPS (HY-D1056) injected C57BL/6 mice. Norquetiapine dihydrochloride can be used for the study of depression and inflammation^{[1][2][3][4][5]}.
