Adipogenesis is critical in development and homeostasis of energy metabolism. However, in these days, the obesity has become prevalent and became a cause of medial complication. Various applications have been suggested to prevent or decrease accumulaiton of energy in fat cells. However, those have little usefulness and have various side effects. Diphlorethohydroxy-carmalol (DPHC) is a phlorotannin compound, with various biological activities in vitro and in vivo. In here, we studied that DPHC could modify the accumulation of fat on integument. The size of adipocytes and thickness of the subcutanous fat tissue was analyzed after treatment of cosmetics contained 0, 0.01, 0.1, 1, or 10 % DPHC using NIS Element D 4.10.00 software (Nikon). The viability and proliferation of cell was analyzed after 0, 0.4, 2, 10, or 50μg/ml of DPHC treatment using MTT (3-[4,5-dimethylthiazo-2-yl]-2,5-diphenyl tetrazolium bromide) assay (R&D system, Cat # 48090-025-k) and measurment of doubling time. Accumulation of lipids in differentiating preadipocytes was analyzed with spectrophotometer after Oil Red-O staining. The size of adipocyte and thickness in skin was decreased in DPHC treated mice. The metabolic activity and doubling of 3T3-L1 were suppressed by DPHC in concentration dependent manner. DPHC also inhibit accumulation of lipids in the adipocyte. The expression of the marker genes for adipocyte differentiation coincided with cytochemical results. Base on them, it is suggested that DPHC has antiobesity effects in integument through suppress accumulation of lipids and suppress the proliferation and differentiation both of adipose stem cells and precursor cells.
