Cell Viability Assay
| Cell Line: | Primary cortical neuronal cells |
| Concentration: | 0.01-1 μM |
| Incubation Time: | 20 minutes (pretreatment); 15 hours (post-incubation) |
| Result: | Concentration-dependently reduced the H 2 O 2 -induced decrease of MTT reduction showing 74.9±2.4% with 1 μM, which was maximal effect. |
Western Blot Analysis

| Result: | Blocked significantly the H 2 O 2 -induced increase of caspase-3 immunoreactivity. |
Bemesetron (0.1, 1 and 10 mg/kg; i.p.) is used in male adult albino mice. The lowest dose do not cause any significant change in catalepsy. However, Bemesetron (1 mg/kg) causes a significant reduction of catalepsy (from 90 min after Haloperidol), while 10 mg/kg significantly potentiates the phenomenon (from 60 min after Haloperidol). The maximum inhibition of catalepsy (about 75%) occurs at 120 min, and the maximum potentiation (about 4.5-times the control value) occurs at 60 min after Haloperidol.
| Animal Model: | Male adult albino mice, weighing 26-36 g |
| Dosage: | 0.1-10 mg/kg |
| Administration: | Intraperitoneally injected, 20 min (pretreatment) +180 min (treatment) |
| Result: | Reduced catalepsy significantly at a dose of 1 mg/kg, whilst 10 mg/kg potentiated the phenomenon and 0.1 mg/kg was found to be without effect. |
