Sabcomeline hydrochloride
Based on 1 Customer Validation
Sabcomeline (SB-202026; Memric) hydrochloride is a muscarinic receptor agonist capable of crossing the blood-brain barrier. Sabcomeline hydrochloride exhibits affinity for all hM1 to hM5 subtypes (pKi=6.72-7.23), and shows near-full agonism at the hM3 receptor, inducing extracellular acidification. Sabcomeline hydrochloride alters the binding kinetics of dopamine D2 receptors through neural network regulation. Sabcomeline hydrochloride also causes minimal cardiovascular changes, effectively reverses spatial memory deficits in rodents and induces conditioned taste aversion. Sabcomeline hydrochloride is an important tool compound in studies of Alzheimer's disease and related neurodegenerative diseases.

Compared with Carbamoylcholine (HY-B1208), Sabcomeline hydrochloride exhibits the lowest potency (≈20%) at the hM1 and hM5 subtypes; moderate potency at the hM4 (≈38%) and hM2 (≈57%) subtypes; and the highest partial agonist potency (≈70%) at the hM3 subtype[1].

Sabcomeline hydrochloride (0.03-0.1 mg/kg; i.p.; single dose 15 minutes prior to testing) significantly reverses 20-s delay-induced T-maze choice accuracy deficits in male Hooded Lister rats, with cholinergic side effects appearing at higher doses of 0.3 mg/kg and above[3].
Sabcomeline hydrochloride (0.3-1.0 mg/kg; i.p.; single dose 15 minutes after saccharin exposure) induces significant conditioned taste aversion in male Hooded Lister rats at a minimum effective dose of 0.3 mg/kg, with 60% inhibition of saccharin intake observed at 1.0 mg/kg[3].

Animal Model:ddY mice (male, 8-9 weeks old)[2]
-
Dosage:0.01-3 mg/kg (i.v.); 0.3 mg/kg (i.p.)
-
Administration:i.v.; i.p. (single dose 30 minutes before tracer injection)
-
Result:Inhibited specific [3H]NMPB binding in cerebral cortex, striatum, and hippocampus with an estimated IC50 of ~0.2 mg/kg.
Reached maximum muscarinic acetylcholine (mACh) receptor occupancy 1 hour after intravenous injection of 0.3 mg/kg, with binding availability returning to control levels by 3-4 hours.
Dose-dependently inhibited specific [3H]QNB binding in the heart.
Decreased the forward rate constant (k3) of [3H]NMSP binding in the striatum by approximately 15%.
Decreased both the forward rate constant (k3) and reverse rate constant (k4) of [3H]raclopride binding in the striatum.
Increased the [3H]raclopride binding potential (BP=k3/k4) in the striatum by approximately 20%.

-
Dosage:0.03 mg/kg; 0.1 mg/kg; 0.3 mg/kg; 1.0 mg/kg
