Activity:

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[3] 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[1]. 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[2]. Raspberry ketone shows cardioprotective action against isoproterenol-induced myocardial infarction in rats, and the effects may be due to its PPAR-α agonistic activity[3].

Protocol:

Cell Assay: Raspberry ketone is dissolved in DMSO.[1]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[1]. Animal Administration: Raspberry ketone is formulated in salad oil.[2]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[2].
