Abstract
Cyclovirobuxine-D (CVB-D) is a Buxus alkaloid 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 a variety of fragments and analogues and evaluated them for the first time as new Cav3.2 inhibitors. Compounds 2-7 exhibited potency against Cav 3.2 channels, and two of them were more active than their parent molecules. As a result of the in vivo experiments, both compounds 3 and 4 showed significantly reduced writhes in the acetic acid-induced writhing test. Studies of molecular modeling have identified possible mechanism(s) of Cav3.2 binding. Moreover, the relationship between structure and activity was studied in a preliminary manner. Our results indicated that compounds 3 and 4 could play an important role in the discovery and development of novel analgesics.
