Abstract
Terfestatins B (1) and C (2), new p-terphenyls bearing a novel unsaturated hexuronic acid (4-deoxy-α-L-threo-hex-4-enopyranuronate), a unique β-D-glycosyl ester of 5-isoprenylindole-3-carboxylate (3) and the same rare sugar, and two new hygromycin precursors, were characterized as metabolites of the coal mine fire isolate Streptomyces sp. RM-5-8. EtOH damage neuroprotection assays using rat hippocampal-derived primary cell cultures with 1, 2, 3 and echoside B (a terfestatin C-3'-β-D-glucuronide from Streptomyces sp. RM-5-8) revealed 1 as potently neuroprotective, highlighting a new potential application of the terfestatin scaffold.Entities:
