and lactone core, is a unique structural element. In this report, we designed and synthesized ABC-ring 6 and CDEFG-ring 7, which are truncated analogues of the northern and southern hemispheres of zoanthenol 5, respectively, and which incorporate all of the functionality of each hemisphere. A preliminary SAR study suggested that the hydrochloride of the CEFG-ring portion is an active pharmacophore for

缩醛和内酯核组成的CDEFG环部分却是独特的结构元素。在本报告中,我们设计并合成了ABC环6和CDEFG环7,它们分别是zoanthenol 5的北半球和南半球的截短类似物,并结合了每个半球的所有功能。
SAR的初步研究表明,CEFG环部分的盐酸盐是抑制白介素6依赖性
