Inhibition of the adipocyte differentiation of 3T3-L1 by an amino acid derivative in fermented foods
Description
[Synopsis]
The inhibitory activity toward the adipose differentiation of 3T3-L1 preadipocyte was determined for ten kinds of fermented foods. A promising activity was detected in the methanolic extracts of miso (fermented soybean paste), soy sauce, tau-jaw (fermented soybean in Thailand, semi-liquid) and su-fu (fermented tofu). Two compounds were isolated from miso as the active principle. They were identified as (-)-( 1S , 3S )- and (-)-( 1R , 3S )-1-methyl-1, 2, 3, 4-tetrahydro-ß-carbolin-3-carboxylic acid. The morphological change in 3T3-L1 adipose differentiation was suppressed in the presence of these compounds. The induction of glycerol-3-phosphate dehydrogenase was suppressed to 55.9 ± 3.1% and 44.9 ± 2.7% by (1S, 3S)-MTCA and (1R, 3S)-MTCA, respectively, at a concentration of 20μg/ ml.
