Twelve undescribed sesquiterpenoids, fomitopins A-L (1-12), were isolated bioassay-guided purification from the bracket fungus (Sw.) P. Karst, and this fungus have been reported to exhibit anti-microbial and anti-inflammatory activities. The structures of 1-12 were elucidated by spectroscopic and spectrometric analyses and their absolute configurations were further confirmed by ECD simulations. Ten isolated compounds were evaluated for their anti-inflammatory potential and compound 11 exhibited the most significant inhibition of superoxide anion generation and elastase release with IC values of 0.81 ± 0.15 and 0.74 ± 0.12 μM. These newly purified sesquiterpenoids could be potential candidates for further anti-inflammatory studies.
通过生物活性导向的纯化方法，从多孔菌（Sw.）P. Karst中分离出12种未描述的倍半萜类化合物，即fomitopins A-L（1-12），据报道这种真菌具有抗菌和抗炎活性。通过光谱和波谱分析阐明了1-12的结构，并通过ECD模拟进一步确定了它们的绝对构型。对10种分离出的化合物进行了抗炎潜力评估，化合物11对超氧阴离子生成和弹性蛋白酶释放的抑制作用最为显著，IC值分别为0.81±0.15和0.74±0.12μM。这些新纯化的倍半萜类化合物可能是进一步抗炎研究的潜在候选物。
