Raspberry ketone is a major aromatic compound of red raspberry, widely used as a fragrance in cosmetics and as a flavoring agent in foodstuff; also shows PPAR-α agonistic activity. IC50 & Target: PPAR-α In Vitro: Raspberry ketone (1, 10, 20, and 50 μM) suppresses adipogenesis and lipid accumulation in 3T3-L1 pre-adipocytes. Raspberry ketone (10 µM) significantly blocks C/EBPα, PPARγ, and aP2 expression and increases the expression of ATGL and HSL, and CPT1B. In Vivo: Raspberry ketone (0.5%, 1%, or 2%) increasses the levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol contents (LDL-C), ISI (insulin-sensitivr index), PPAR-α and LDLR, decreases the serum levels of AST (aspartate aminotransferase), ALT (alanine aminotransferase), ALP (alkaline phosphatase), IRI (insulin resistance index), GLU (glucose), INS (insulin-sensitivr index), LEP (leptin), and TNF-α in rats compared with a high-fat diet-induced NASH model. Raspberry ketone also causes increased SOD activities. Raspberry ketone shows cardioprotective action against isoproterenol-induced myocardial infarction in rats, and the effects may be due to its PPAR-α agonistic activity.
Protocol:Cell Assay: Raspberry ketone is dissolved in DMSO.For the cytotoxicity study, 3T3-L1 pre-adipocytes are cultured and differentiated. After Raspberry ketone treatment for 4 d in DMEM containing 10% fetal bovine serum, the lactate dehydrogenase (LDH) concentration in the medium is immediately detected with the CytoTox 96 nonradioactive cytotoxicity assay kit. Animal Administration: Raspberry ketone is formulated in salad oil.During the experimental period, the animal room holds four rats per cage, with free access to water and food, under conditions of temperature controlled at 20-26°C, humidity at 40-70%, and a 12/12-h day-night light cycle. Rats are fed with normal diet for 1 week and then randomly divided into five groups: normal control (NC) group (n=8) fed normal diet for 8 weeks, the model control (MC) group (n=8) fed high-fat diet (82% standard diet, 8.3% yolk powder, 9.0% lard, 0.5% cholesterol, and 0.2% sodium taurocholate), the Raspberry ketone low-dose (RKL) group (n=8), the Raspberry ketone middle-dose (RKM) group (n=8), and the Raspberry ketone high-dose (RKH) group (n=8). Rats are first fed with high-fat diet for 4 weeks, and then these rats are given intragastrically 0.5%, 1%, or 2% Raspberry ketone. The first two groups of rats are intragastrically administered salad oil at the same dose (2 mL/day per rat) once a day at 10:00 a.m., lasting for 4 weeks.
