| 英文摘要 | Objective To isolate and identify fatty acids of the green alga Caulerpa racemosa (ForsskAl) J. Agardh from the South China Sea and to evaluate their biological activities. Methods Compounds were isolated by means of various chromatographic techniques including silica gel and Sephadex LH-20 column chromatography and reverse phase HPLC. Their structures were elucidated on the basis of spectroscopic analysis including lD NMR, MS,and optical rotation. All of the isolates were evaluated for their inhibitory activity against PTP1B by enzyme-labelled method and neuro-protective activity against OGD-, H_2 0_2-,Alphabeta_(25-35)-caused damage on SH-SY5Y cells by MTT method. Results Twelve known fatty acids and related derivatives were isolated and identified as palmitic acid (1), stearic acid (2),diethyl octadecanedioate (3),glycerin monotricosanate (4),(8E)-heptadec-8-en-7-one (5),(8Z, 11Z)-heptadeca-8,11-dienoic acid (6),ethyl linolenoate (7),(4Z,7Z,10Z,13Z)-ethyl hexadeca-4,7,10, 13-tetraenoate (8),beta-dimorphecolic acid (9),beta-dimorphecolic acid -(10),(9R,10E, 12Z)-9-hydroxyoctadeca-10,12-dienoic acid (11),and (9R, 10E)-9-hydroxyoctadec-10-enoic acid (12),respectively. Conclusions Compound 5 was first discovered as a natural product. Moreover, except for compounds 1 and 2, this is the first report that described the isolation of all of compounds from Caulerpa racemosa, of which 3,4, and 8-12 were obtained for the first time from marine organisms and 6 and 7 were first isolated from the genus Caulerpa. Compound 2 moderately attenuated the OGD (oxygen-glucose deprivation)-induced SH-SY5Y cell damage with 9. 87% increase in cell viability at the concentration of 10 muMu,while 5 also showed moderate neuro-protective activity against the Abeta_(25-35)-induced SH-SY5Y cell damage (6. 28% increase at 10 muM). Compounds 1,2,5,11,and 12 exhibited potent PTP1B inhibitory activity with IC50 values of 5. 390. 55,14. 781. 85,47. 403. 57, 40. 343. 28,and 35. 23 2. 65 muMu, respectively. |
