their phenethyl esters were synthesized and evaluated as inhibitors of cys-LTs release. Artepillin C, baccharin, and kaempferide were the major active components of the ethanol extract. The inhibitory activity of artepillin C phenethyl ester was comparable to that of existing LT synthesis inhibitors.
研究了巴西绿色蜂胶乙醇提取物对变应性鼻炎患者Cry j1诱导的cys-白三烯和组胺从外周白细胞释放的影响。提取物抗过敏特性的关键机制之一是抑制cys-LTs释放。此外,合成了一系列蜂胶成分及其苯乙基酯,并评估了它们是cys-LTs释放的抑制剂。Artepillin C,baccharin和kaempferide是乙醇提取物中的主要活性成分。青霉素C苯乙酯的抑制活性与现有的LT合成抑制剂相当。
