초록

Obesity is a worldwide disease and one of the major risk factors. Virus among many factors can lead to obesity. Adenovirus 36 (Ad-36) is the adipogenic virus linked with human obesity. Nevertheless, there is no drug to treat both Ad-36 infection and obesity associated with virus. For the precedent study on anti-cholesterol test, Distylium racemosum (D. racemosum), Quercus salicina (Q. salicina) and Raphiolepis indica (R. indica) were selected. This study was carried out to evaluate the anti-cholesterol effects, anti-lipid effects and inhibition of Ad-36 replication from three extracts. D. racemosum (50 μg/mL) inhibited lipid accumulation on 3T3-L1 adipocyte. D. racemosum inhibited adipocyte differentiation through suppression of regulator peroxisome proliferator-activated receptor- γ (PPARγ) genes and adipocyte-specific genes such as adipocyte protein 2 (aP2). D. racemosum inhibited replication of Ad-36 at 50 μg/mL of concentration. Therefore, the extract of D. racemosum could be a candidate for development of anti-Ad-36 and anti-obesity drugs.
