Puerarin
Based on 32 publication(s) in Google Scholar
Puerarin is an isoflavone extracted from Pueraria root and is a 5-HT2C receptor antagonist. Puerarin inhibits the dorsal motor nucleus of the vagus (DMV)-vagus nerve pathway, which in turn leads to decreased fat absorption.

5-HT2C Receptor |
Puerarin inhibits the expression of LPS-induced iNOS, COX-2 and CRP proteins and also suppresses their mRNAs from RT-PCR experiments in RAW264.7 cells. The inhibition of iNOS, COX-2 and CRP expression is due to a dose-dependent inhibition of phosphorylation and degradation of I-κB, which resulted in the reduction of p65NF-κB nuclear translocation. The effect of puerarin-mediated inhibition of LPS-induced iNOS, COX-2 and CRP expression is attributed to suppressed NF-κB activation at the transcriptional level[1].
Puerarin is a novel open-channel blocker of IK1, which may underlie the antiarrhythmic action of puerarin. Puerarin competes with barium, an open-channel blocker of IK1, to inhibit IK1 currents[2].

Early-stage renal damages can be significantly improved by puerarin, possibly via its suppression of ICAM-1 and TNF-α expression in diabetic rat kidneys[4].

Protocole
RAW264.7 cells are maintained at subconfluence in 95% air and 5% CO2 humidified atmosphere maintained at 37°C. The medium used for routine subculture is Dulbecco’s Modified Eagle’s Medium supplemented with 10% fetal bovine serum, penicillin (100 units/mL) and streptomycin (100 μg/ mL). An MTT assay is used to measure the viability of the cells after treatment with puerarin. After the supernatants are removed for nitrite determination, cells are incubated at 37°C with MTT (0.05 mg/mL) for 4 h, and the optical density is measured at 540 nm. The concentrations of puerarin are10, 20, 40 and 100 μM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Rats: A cohort of healthy male SD rats (7 weeks old) are randomLy divided into a control group, a model group, and a puerarin treatment group with high (H), moderate (M), and low (L) dosage. Puerarin is re-suspended in 0.9% saline and is given by intra-gastric intubation at various concentrations (0.25 mg/(kg×d) for L group, 0.5 mg/(kg×d) for M group, and 1.0 mg/(kg×d) for H group) each day for 8 consecutive days. An equal volume of saline is administered to control and model rats during the same time period[4].
Mice: Forty male ICR mice (weight: 20-22 g) are acclimatized with a daily 12 h light:12 h dark cycle at 22±2 °C room temperature and 55%±5% relative humidity. After 1 week of adaption, the mice are randomLy divided into four groups with ten mice per group. Genistein and puerarin are applied to the mice in sodium carboxymethyl cellulose solution with an equimolar concentration of 0.1 M (gastric volume: 3 mL kg-1 body weight)[3].
