Cyclovirobuxine D (CVB-D) is the main active component of the traditional Chinese medicine Buxus microphylla. Cyclovirobuxine D induces autophagy and attenuates the phosphorylation of Akt and mTOR. Cyclovirobuxine D inhibits cell proliferation of gastric cancer cells through suppression of cell cycle progression and inducement of mitochondria-mediated apoptosis. Cyclovirobuxine D is beneficial for heart failure induced by myocardial infarction.

How to use

In Vitro:

Cyclovirobuxine D (0-240 µM ;24-72 hours) shows a concentration- and time-dependent reduced cell viability after CVB-D treatment, only 10% MGC-803 cells and 20% MKN28 cells are alive at 72 h after treatment with 240 µM. Cyclovirobuxine D (0-120 µM; 48 hours) arrests the cell cycle of gastric cancer cells at S phase in a concentration-dependent manner. Cyclovirobuxine D (0-120 µM; 48 hours) leads to apoptosis in gastric cancer cells in a concentration-dependent manner, especially early stage apoptosis. Cyclovirobuxine D (0-120 µM; 48 hours) causes apoptosis via up-regulation of the apoptosis- related proteins, cleaved Caspase-3 and ratio of Bax/Bcl-2, in gastric cancer cells.
