在配合物结构中，茜素红配体中的两个羟基氧均与钛键合，形成五元环状二茂钛配合物，且化合物中还存在两个结晶水

In the coupling reaction of 4 with 2-methyl-1-buten-3-yne the four- membered ring ligand is transferred to enyne to give the substituted eta3-butadienyl complex 5 containing the cyclobutenonyl group.

在4与2-甲基-3-炔-1-丁烯进行偶合反应后，四环结构仍然稳固存在，并转移到烯缺上形成一个含有四环结构的错合物5。

SIBLINGs, or Small Integrin-Binding Ligand N-linked Glycoproteins, are a family of five proteins that help mineralize bone but can also spread cancer.

SIBLINGs，或称为小整合素结合配体N-连锁糖蛋白，是一种由5个蛋白组成的家族，这些蛋白可帮助骨骼矿化，但也能促使癌症扩散。

The catalytic performance of cobalt complexes which contain mono- or bidenate phosphorus, nitrogen ligand on displacement reaction have been studied.

用建立的喷雾反应过程数学模型计算所得结果也与实验数据相吻合，验证了该数学模型的普遍性。

Objective To investigate the change and significance of serum soluble Fas and soluble Fas ligand in lupus nephritis.

摘 要：目的研究狼疮肾炎患者血清sFas和sFasL的变化及意义。

Tb3+ in DTPA-Tb is replaced by Np4+ giving DTPA-Np and Tb3+, then the free Tb3+ complex with Tiron producing Tiron-Tb which is a strong fluorescence substance. We use the fluorescence signal of the ligand to measure Np4+ in the system. The high sensitivity of Tiron-Tb makes the method for neptunium sensitive.

测定Tb~(3+)有一个极灵敏的方法，Tb~(3+)和Tiron结合生成强荧光的络合物Tiron-Tb，其检测下限可达4.8×10~(-12)g／ml Tb~(3+)，利用荧光法检测Tiron-Tb的高灵敏性，从而实现镎的间接测定。

The complexes can combine with Ct-DNA strongly. The results of antitumor activities show that the complexes have no antitumor activity, which are different from benzoic acid nitrogen mustard, indicating counteraction between rare earth and the ligand. The possible mechanism was also proposed.

抗肿瘤活性表明，这类配合物对〓、〓无活性，这与配体较好的活性相差甚远，说明两者之间存在强的拮抗作用，文中最后对其可能的机理也进行了讨论。
