Abstract
A chemical investigation of Sigesbeckia glabrescens Makino identified four compounds. On the basis of spectroscopic data, they were determined to be ent-pimarane-type diterpenoids and their analogues, among which were two previously undescribed compounds, Sigesbeckia K (1) and Sigesbeckia L (2). The anti-inflammatory effects of these compounds were evaluated by testing their inhibition of LPS-induced NO production in BV2 microglial cells, which revealed potential inhibitory effects with IC50 value at 62.56 μM and compared with the positive control minocycline (IC50 32.84 μM).

摘要
Sigesbeckia glabrescens Makino的化学研究确定了四种化合物。根据光谱数据,它们被确定为ent -pimarane 型二萜及其类似物,其中有两种以前未描述的化合物 Sigesbeckia K ( 1 ) 和 Sigesbeckia L ( 2 )。通过测试它们对 BV2 小胶质细胞中 LPS 诱导的 NO 产生的抑制作用来评估这些化合物的抗炎作用,这揭示了潜在的抑制作用,IC 50值为 62.56 μM,并与阳性对照米诺环素 (IC 50 32.84 μM)进行比较.
