چکیده انگلیسی
Chromatographic purification of the methanolic extract from the soft coral Sarcophyton pauciplicatum led to the isolation of three polyhydroxylated steroids 1-3, including a new compound, sarcopanol A (1). Their structures were elucidated by spectroscopic analysis and by comparison of the spectroscopic data with those of similar compounds previously reported in literature. The anti-inflammatory effects of isolated compounds were evaluated using nuclear factor kappa B (NF-κB) luciferase and reverse transcription polymerase chain reaction (RT-PCR). The effect of isolated compounds on cell growth was evaluated by MTS assays. Compounds 1 and 2 significantly inhibited TNFα/INFγ-induced NF-κB transcriptional activity in human keratinocyte (HaCaT) cells in a dose-dependent manner, with EC50 values of 8.27 ± 3.28 and 26.07 ± 5.59 μM, respectively. Furthermore, the transcriptional inhibition of these compounds was confirmed by a decrease in cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and intercellular adhesion molecule-1 (ICAM-1) gene expression levels in HaCaT cells.
