Zatosetron maleate is a potent and selective 5HT3 receptor antagonist.
Acute administration of 0.1 (n=21) and 0.3 (n=5) mg/kg Zatosetron maleate (Zatosetron) in male rats, but not 0.01, 0.05, 1.0 or 10 mg/kg (n=5, 3, 6 and 4, respectively) Zatosetron maleate or saline (n=5), leads to a significant reduction in the number of spontaneously active A10 dopamine cells. The number of spontaneously active A10 dopamine cells is not significantly different from 30 to 60 min post i.p. Zatosetron maleate (0.1 mg/kg) administration, shows a significant decrease by 60 to 90 min (0.65±0.11, P=0.03, n=5), a larger decrease by 90 to120 min (0.53±0.08, P=0.004, n=5) and remains at this significantly decreased level from 2 to 3 h (0.50+0.05, P=0.0004, n=5). Single-unit recordings show that Zatosetron maleate inhibits the activity of A10 dopamine cells following i.v. administration (ED50=0.12 mg/kg, n=8). Chronic administration of 0.1 mg/kg (n=16) Zatosetron maleate, but not 0.01, 1.0 or 10 mg/kg (n=4, 8 and 7, respectively) Zatosetron maleate or saline (n=5), leads to a significant reduction in the number of spontaneously active A10 dopamine cells[2].

Animal experiment: | Male rats are used and Zatosetron maleate (Zatosetron) is prepared as an aqueous solution. Acutely treated animals receive i.p. injections of Zatosetron maleate or saline 2 h before electrophysiological recordings; Chronically treated animals receive injections (i.p.) of Zatosetron maleate or saline once daily for 21 days, and receive their last injection 2 h before electrophysiological recordings. After completion of nine tracks, some animals are administered either apomorphine HCI (0.14 or 0.01 mg/kg i.v.) or haloperidol (0.1 mg/kg i.v.) and the number of dopamine cells is then counted in three additional tracks[2]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
