BioAssay: AID 628224

Inhibition of EGFP-tagged GR nuclear translocation in human HaCaT cells at 250 uM after 1 hr using Hoechst staining by fluorescence microscopy relative to control

Marine derived actinomycetes have become an important source of bioactive natural products. Here we report the structure and bioactivity of the bendigoles D-F (1-3), 3-keto sterols isolated from the new marine sponge derived bacterium, Actinomadura sp. SBMs009. The isolation of these compounds was guided by a novel high-content screen for NF-kappaB and glucocorticoid receptor (GR) activity, and more ..

Title: Bendigoles D-F, bioactive sterols from the marine sponge-derived Actinomadura sp. SBMs009.

Abstract: Marine derived actinomycetes have become an important source of bioactive natural products. Here we report the structure and bioactivity of the bendigoles D-F (1-3), 3-keto sterols isolated from the new marine sponge derived bacterium, Actinomadura sp. SBMs009. The isolation of these compounds was guided by a novel high-content screen for NF-kappaB and glucocorticoid receptor (GR) activity, and cytotoxicity assays. The structures of 1-3 were determined by detailed analysis of NMR, MS, and single crystal X-ray diffraction data. Interestingly, 1 displayed cytotoxicity against the L929 (mouse fibroblast) cell line with an IC(50) approximated to 30 muM and was the most active inhibitor of GR-translocation, while 3 was the most effective inhibitor of NF-kappaB nuclear translocation with an IC(50) of 71 muM.
