Cyclovirobuxine-D (CVB-D) is a Buxusalkaloid and a major active constituent in the Chinese medicinal herb Buxus microphylls. Traditionally, the natural alkaloid cyclovirobuxine-D has a long history of use as a traditional Chinese medicine for cardiovascular diseases as well as to treat a wide variety of medical conditions. As we found that CVB-D inhibited T-type calcium channels, we designed and synthesized
Cyclovirobuxine-D (CVB-D) 是一种黄杨生物碱,是中药黄杨的主要活性成分。传统上,天然生物碱环维黄杨星-D 作为治疗心血管疾病以及治疗多种疾病的中药有着悠久的历史。由于我们发现CVB-D抑制T型钙通道,我们设计并合成了多种片段和类似物,并首次将它们作为新的Ca v 3.2抑制剂进行评估。化合物2 – 7表现出对抗 Ca v 3.2 通道的效力,其中两个比其母体分子更活跃。体内实验的结果是,化合物3和4在乙酸诱导的扭体试验中均显示出显着减少的扭体。分子模型研究已经确定了 Ca v 3.2 结合的可能机制。此外,还初步研究了结构与活性之间的关系。我们的结果表明化合物3和4可以在新型镇痛药的发现和开发中发挥重要作用。

Investigation of the weak-base fractions of two species, B. microphylla Sieb. et Zucc. var. suffruticosa Makino and B. microphylla Sieb. et Zucc. var. suffruticosa Makino forma major Makino, has led to the isolation of ten new alkaloids. In addition, another new alkaloid was isolated from the strong-base fraction of the latter species. These alkaloids are structurally closely related, and their interconversion

an intermediate readily accessible from cycloartenol/cyclolaudenol has been transformed into cyclobuxophyllinine-M, an alkaloid isolated from certain Buxus Spp. This compound has been earlier converted into the closely related alkaloids cyclobuxophilline-K and buxanine-M. The present work formally constitutes the synthesis of these alkaloids from cycloartenol.
