Biological Activity
VMAT2[1]
Reserpine hydrochloride is an inhibitor of the vesicular monoamine transporter 2 (VMAT2). Reserpine hydrochloride displays a significant on the density of dopamine D1 receptors (F2,12=8.81, p<0.01) in the rat striatum. The affinity (Kd) for the dopamine D1 and D2 receptors during withdrawal from acute and chronic administration of reserpine is not change[1]. IC50 values of 43.9 and 54.9 μM are obtained after 1 day of treatment with Reserpine hydrochloride in JB6 P+ and HepG2-C8 cells, respectively. Reserpine hydrochloride induces luciferase activity in a dose-dependent manner at concentrations ranging from 5 to 50 μM, and no significant induction is observed at concentrations lower than 5 μM. Results demonstrate that Reserpine hydrochloride (2.5 to 10 μM) also increases the protein expression of Nrf2, HO-1, and NQO1. Reserpine hydrochloride at concentrations of 2.5 to 10 μM decreases the mRNA expression of DNMT1, DNMT3a, and DNMT3b in a concentration-dependent manner in JB6 P+ cells after 7 days of treatment. Reserpine hydrochloride at 10 μM generates a significant difference for DNMT3a expression (p<0.05)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
Reserpine can be used in animal modeling to create gastrointestinal ulcer and depression models. Withdrawal from chronic (14 days) but not acute reserpine (48 hours) significantly decreases immobility time (F2,18=3.68, p<0.05) and increases climbing time (F2,18=4.48, p<0.02) in rats, without altering swimming time in the forced swim test (FST) (F2,18=1.78; NS) compared to control animals. A dose of 5 mg/kg body weight of Reserpine significantly increases the urinary excretion of vanillylmandelic acid (VMA). Animals treated with Reserpine excrete more 5-hydroxyindoleacetic acid (5-HIAA) than controls. Reserpine treatment results in dose-dependent hypotension. Compared to controls, doses of 0.5, 1, 5, 10, and 15 μg/kg of Reserpine significantly (p<0.01) reduce blood pressure[1][3].
Administration: 5 mg/kg • ip • 18 h before sacrifice
Mice: ICR mice • male • 7 weeks old[5]
Administration: 10 mg/kg • ip • once daily for 3 days
(2)The level of cancer induction was identified by specific biochemical markers such as serum gastrin level, TBARS, and glutathione followed by histopathological analysis at two-time periods for 8 and 16 week.
Molecular changes: In the reserpine-induced gastric ulcer control mice, the gastric secretion volume was increased, the pH value (1.04) was decreased, the serum cytokine levels of IL-6, IL-12, TNF-α and IFN-γ was increased.
Administration: 0.5 mg/kg • ip • once per day for 14 days
Mice: C57BL/6 mice • male • 7 weeks old[8]
Administration: 0.5 mg/kg • ip • once per day for 10 days
Molecular changes: Reserpine administration significantly increased cortical contents of MDA (malondialdehyde), reduced GSH (glutathione), increased TNF-ɑ and reduced BDNF (brain derived neurotropic factor). Showed a significant decrease in cortical nor-epinephrine (NE), serotonin (5-HT), and dopamine (DA)

Protocol
After incubation for 24 h, JB6 P+ cells (1×105 cells/10-cm dish) are treated with various concentrations of Reserpine hydrochloride. Whole cell lysates are prepared from the treated cells using radioimmunoprecipitation assay buffer supplemented with a protease inhibitor cocktail, and a BCA kit is used to determine protein concentrations[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
JB6 P+ cells are seeded in 96-well plates containing Minimum essential media (MEM) at a density of 1×104 cells/mL (100 μL/well) for 1, 3, and 5 days, and HepG2-C8 cells are seeded in plates containing DMEM. After incubation for 24 h, the cells are treated with either DMSO or various concentrations of Reserpine hydrochloride. For JB6 P+ cells, the medium is changed every 2 days for the 3-day and 5-day treatments. Cell viability is assessed using a MTS assay kit according to the manufacturer’s instructions. The absorbance of the formazan product is read at 490 nm, and the cell viability is calculated and compared with the DMSO control group[2].

Albino rats of either sex weighing between 100 to 150 g are used in the study. They are acclimatized to the laboratory conditions for at least 10 days prior to the experiment and are provided with standard diet and water ad libitum with 12 h light and dark cycle. Animals are divided into different groups of six each and are housed individually in metabolic cages. Group 1: Control animals treated with DMSO intraperitoneally at a dose of 0.1 mL/100 g body weight. Group 2: Animals administered intraperitoneally with Reserpine hydrochloride at a dose of 5 mg/kg body weight. The 24 h urine samples from the point of drug administration are collected for each animal[3].
