Celastrusorbiculatus afforded 10 terpenoids and eight known compounds. Their structures were established on the basis of spectroscopic and chemical methods. Celastrol and its dimers and adducts displayed moderate inhibitory activity against T cell proliferation. The reaction of celastrol under acidic conditions was undertaken, and a mechanism is presented, which may help towards modification of its structure and elucidation
Celastrusorbiculatus 根皮的植物化学研究提供了 10 种萜类化合物和 8 种已知化合物。它们的结构是在光谱和化学方法的基础上建立的。Celastrol 及其二聚体和加合物显示出对 T 细胞增殖的中等抑制活性。在酸性条件下进行了celastrol的反应,并提出了一种机制,这可能有助于修饰其结构和阐明天然celastrol衍生物的生物遗传途径。
