随后将手性不饱和脂肪酸和氨片段进行酰胺化反应构筑了malyngamide M的基本骨架，再将Z-烯氯转化为E-烯氯完成了目标分子的全合成，高立体选择性地构筑了末端烯氯结构，为制备其它含有类似烯氯结构的malyngamides探索出行之有效的合成路线。

These two series of probes differ in their mechanism of action. The first series exploits the concept of suicide substrate. When the probe is hydrolyzed by the target sulfatase, it will release an intermediate that undergoes elimination to form a reactive quinone methide which in turn reacts with nearby nucleophiles. The second series belongs to an electrophilic reagent which utilizes a cyclic sulfamate moiety serving both as the recognition unit and the trapping device.

这二系列标示分子的主要差异在於其标示机制，第一系列是源自於自杀性受质的概念，利用水解后的中间体会生成高反应性的quinone methide，来达到标示的效果；第二系列则是属於亲核性试剂型，采用环状胺基磺酸衍生物做为辨识端及捕捉机制，预期在其进入酵素的受质结合区后能与酵素催化中心形成共价键结。

The analysis of SAR reveals that the activities of target compounds are closely associated with the electron-withdrawing substituents at the para position of 1-aryl-1, 2, 4 -triazoles as well as with the substituents such as sulfonyl and methylthio groups at the 3 position of 1, 2, 4 -triazoles; And the introduction of sulfamoyl moiety at the para position of 5-aryl-1,2,4-triazoles also has significant influence on the anti-inflammatory activity of these compounds.

Triazole is an interesting moiety, which plays an important role in biological activity. In recent years, many efforts have been paid to develop 1,2,3-triazole derivatives on the basis of many lead compounds with various pharmacological activities, and quite a few successful examples have been seen. Unfortunately, in contrast with 1,2,4-triazole, 1,2,3-triazole has only a few ways to be prepared.
