  Structural analysis and antitussive evaluation of five novel esters of verticinone and bile acids

  摘要：

  Shedan-Chuanbei powder, a complex of traditional Chinese medicine preparation, which consists of Snake Bile (Chinese name "Shedan") and Fritillariae Cirrhosae (Chinese name "Chuanbei"), is the most popular antitussive and expectorant formulation in Chinese communities. However, the clinical application of Shedan-Chuanbei powder is now stringently limited because of the shortage of the two crude medicinal materials, especially for the sake of animal protection. In addition, the inherent defects of the most of the complex of traditional Chinese medicine such as the indistinct basal phartnacodynamic materials and the difficulties in quality control had blocked them heading into the international medicinal market. So we attempted to seek new substitute for Shedan-Chuanbei powder for antitussive drugs. In order to gain some new compounds with better bioactivity and attenuated toxicity, we tried to combine two kinds of drugs through ester bond. Enlightened with "combination principle" in drug discovery, we synthesized five novel esters of verticinone and bile acids, both of which are the major bioactive components in Shedan-Chuanbei powder. We then evaluated the antitussive activity and the acute toxicity of the five ester-linked compounds. The five ester-linked Compounds had much more potent antitussive activity and expectorant activity than single bile acids at the same doses, and had equivalent antitussive activity and expectorant activity in comparison with about double moles dose of the monomer verticinone. Especially, cholic acid-verticinone ester had much more potent antitussive effects than the monomer verticinone or cholic acid at the same dose. A further acute toxicity study showed that the LD50 values of the five ester-linked compounds exceeded 3.5 g/kg by intraperitoneal injection in mice. Based on the studies of pharmacology and acute toxicity, the five ester-linked compounds have synergic pharmacodynamic action and attenuated toxicity compared with single verticinone and single bile acids.
