Dihydro-β-erythroidine hydrobromide BiologicalActivity

Description	Dihydro-β-erythroidine (DHβE) hydrobromide is a potent, orally active, and competitive antagonist of neuronal nAChRs. Dihydro-β-erythroidine hydrobromide shows selectivity for α4β4 and α4β2 nAChRs, with IC50s of 0.19 and 0.37 μM, respectively. Antidepressant-like activities[1][2][3].

In Vivo	Dihydro-Beta-Erythroidine hydrobromide (DHβE hydrobromide; 10 nmol/0.5 μL) is infused into the respective areas prior to a systemic nicotine injection (0.2 mg/kg; SC). DHβE infused into the ventral tegmental area (VTA), nucleus accumbens (NAcc), or infralimbic (IL) cortex, but not prelimbic (PrL) cortex, attenuated nicotine-enhanced responding for a conditioned reinforcer (CRf)[2]. The co-administration of Dihydro-Beta-Erythroidine hydrobromide (5.0 mg/kg; s.c) with nicotine (0.2 and 0.4 mg/kg; s.c.) prevents the development of conditioned taste aversions (CTAs)[4]. Animal Model: Male hooded Lister rats[4] Dosage: 0.5, 1.6 and 5.0 mg/kg Administration: S.c. Result: A complete blockade of the nicotine effect produced by the training dose of nicotine (0.2 mg/kg).
