摘要

Seven new isoprenyl phenolic ethers, namely fimbriethers A‒G (1‒7), were isolated from the fermented broth of the termite nest-derived medicinal fungus Xylaria fimbriata YMJ491. Their structures were determined by spectroscopic data analysis and compared with those reported. The effects of all the isolates at a concentration of 100 μM on the inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-induced murine macrophage RAW 264.7 cells were evaluated, and all of them exhibited NO production inhibitory activity with E max values ranging from 4.6 ± 2.0% to 49.7 ± 0.5% without significant cytotoxicity. In addition, these seven compounds did not alter phenylephrine-induced vasocontraction in isolated intact thoracic aortic rings from C57BL/6J mouse, indicating 1‒7 were not involved in the regulation of endothelial NOS-mediated NO production.
