Four undescribed guaiane sesquiterpenes, aquisinenoids I-L (2-5) and five known compounds were isolated from the resins of Aquilaria sinensis. Their structures were deduced based on spectroscopic data analysis, X-ray crystallography and ECD calculations. Biologically, compounds 1, 5, 6 and 9 showed anti-renal fibrosis activity, significantly reducing the levels of fibronectin, collagen I, and α-SMA. Compounds 2-4, 7 and 8 could reduce one or two of these proteins at non-toxic concentrations in TGF-β1 induced NRK-52E cells.
从白木香树脂中分离得到了4个未描述的愈创木烷型倍半萜——沉香新素I-L（2-5）以及5个已知化合物。通过光谱数据分析、X射线晶体学和电子圆二色光谱（ECD）计算推导了它们的结构。生物学实验表明，化合物1、5、6和9具有抗肾纤维化活性，可显著降低纤连蛋白、I型胶原蛋白和α-平滑肌肌动蛋白（α-SMA）的水平。在转化生长因子-β1（TGF-β1）诱导的NRK-52E细胞中，化合物2-4、7和8在无毒浓度下可降低其中一种或两种蛋白质的水平。
