It has been reported that the leaf and root extracts of Petasites hybridus relieve gastrointestinal pain, lung-disease such as asthma and cough, as well as spasms of the urogenital-tract, and even suppress the proliferation of human T24 bladder carcinoma cells. In 2000, S-petasin had been found to decrease the testosteron releasing by rat testicular interstitial cells.
此植物体及其萃取物应用在治疗使用上已约有两千年的历史,在1994年的研究中指出其粹取物对於人类膀胱癌细胞株(T24)具有抗增殖的效果,且於2000年,本实验室研究发现其粹取物-硫蜂斗菜素具有抑制大鼠间质细胞分泌睪固酮的效用,然而它对於人类前列腺癌细胞株是否也会造成毒杀效应,目前则尚未有文献探讨。

It was found that La〓 does not affect the binding affinity between calmodulin and Polistes Mastoparan, a known calmodulin binding peptide, neither the conformation of the ternary complex. Excessive amount of La〓 result in the decrease of the binding constant and the disrupted conformation. The binding affinity of La〓 to calmodulin increased in the ternary complex (La〓-CaM-Mas/Mas X), which suggested the coordination between the two global domains. The binding priority between the two global domains is also changed: La〓 more is likely to bind to the C-terminal of calmodulin than to N-terminal, thus facilitates the binding of Mas/Mas X to the C-terminal of calmodulin as the first step of the Mas/Mas X binding.
在以钙调蛋白结合肽—Polistes Mastoparan和Mastoparan X为对象的研究中,我们发现,除非过量,否则La〓的存在不影响钙调蛋白与Mas间的结合常数以及构象;过量的La〓(La〓/CaM摩尔比>4)将引起钙调蛋白结合功能的下降,同时明显改变金属-钙调蛋白-Mas三元复合物的构象;La〓对Ca〓CaM-Mas的N末端表现高度选择性,显示了在三元复合物中两种离子间的协同效应;在三元体系中,La〓与钙调蛋白的亲和力明显上升,而且亲和力上升的程度因钙调蛋白结合肽的不同而有明显差异,显示了作用的选择性;Mas和MasX的存在改变了La〓在钙调蛋白上的结合顺序,La〓很可能优先与C末端结合,从而使Mas/Mas X首先与C末端结合,该顺序与钙离子相同;La〓的参与使三元复合物在动力学上更加稳定。

Finally, two tetranuclear Cu~(2+) complexes were constructed from a new salen ligand with alkoxo groups. The two complexes were obtained by the reaction of the same ligand with Cu~(2+) in different solvents, i.e., a stage tetranuclear complex and a pseudo-cubane tetranuclear complex in MeOH and THF, respectively.

The carboxyl of the tripodal ligand is a goodbridging group. The building blocks are linked together by the bridging group andother weak interactions (hydrogen bond and π-π stacking interaction, etc), thusgenerating a one, two or three-dimensional metal complexes.2. Studies on the fluorescence properties of the lanthanide complexes indicated that:(1) The excitations in the ligand-based π-π〓 transitions cause the structuredemission of lanthanide complexes while the ligand luminescence is completelyquenched showing that ligand-to-metal energy transfer occurs.
三脚架配体所带的羧基是一个很好的桥联基团,配合物的结构基元通过这种基团的桥联作用及其它一些弱的作用力(如氢键、π-π堆积作用等)联系起来,构成了一维、二维或三维的超分子空间结构。2、稀土配合物的发光研究发现:(1)用配体的π-π〓跃迁波长进行激发,配合物均显示出稀土离子的特征发射峰,同时,配体的荧光峰没有出现,这说明在三脚架配体与稀土离子间进行了有效的能量传递。
