ABSTRACT
Objective To investigate the chemical constituents of marine sponge Mycale sp.collected from the South China Sea.Methods The ethyl acetate extract of the marine sponge Mycale sp.was separated and purified by repeated column chromatography on silica gel, Sephadex LH-20 and reversed-phase high-performance liquid chromatography (RP-HPLC).The structures of these compounds were identified by means of various modern spectroscopic techniques and comparison with their physicochemical properties to reported data.The tumor cell growth inhibitory activities of these compounds against human breast cancer cell lines MCF-7 and human lung cancer cell lines PC9 were tested by Cell Counting Kit-8 (CCK-8) method.Results Ten compounds were isolated and identified as cyclo-(Pro-Ile)(1),cyclo-(Pro-Leu)(2),cyclo-(Ile-Leu)(3),cyclo-(Phe-Pro)(4),cyclo-(Phe-Val)(5),cyclo-(Phe-Leu)(6),cyclo-(Phe-Ile)(7), 2′-deoxythymidine (8), thymine (9), 5-hydroxy-3,4-dimethyl-5-pentyl-2(5H)-furanone (10).These compounds showed weak tumor cell growth inhibitory activities toward cells MCF-7 and PC9 in vitro.Conclusion Compounds 1, 2, 4, 5, 6, 7 and 10 were isolated from the sponge Mycale sp.for the first time.It is the first time to report the antitumor activity evaluation for compounds 1~10.
ABSTRACT
@#Objective To explore the effects of high temperature aerobic training on body and mind health of obese young and middle- aged women. Methods 50 obesity middle-aged and young females from the yoga clubs were included. Their physical component, physiological functional components were compared before and after 1-year high temperature aerobic training. Results All the related parameters of exercise improved significantly (P<0.05), as well as the psychological status. Conclusion Yoga, as a representative of the high temperature aerobic training, can not only effectively improve the body physique, reduce lipid-lowering weight, but also improve the physiological function and psychological adjustment
