In the reasonable drug molecular design,analyzing the conformations of the substrate without three-dimension structure and confirming its active conformation are very important to illustrate the spatial shape and active site of target enzyme. The active conformation of protoporphyrinogen IX substrate of protoporphyrinogen oxidase has been established using the Distance Comparisons DISCO method. In this paper, four different conformational molecules of Protogen IX and crystal molecule of diphenylethersAF are analyzed by comparing their geometry parameters. The results show the lower energy active conformation from the DISCO model is more reasonable.

In this paper, the stable Au complexes are classified according to the coordination atoms and their characteristic structure. The recent development of the researches on the antitumor activity of Au complexes including the structure-activity relationship, biological targets and the mechanisms of action are reviewed. The structure of the coordination ligand and the leaving group have great impact on the in vitro cytotoxicity of the Au complex. Many physical and biological methods are introduced to study the interaction between the Au complexes and the suspected bio-target, such as DNA, protein, mitochondrion, thio-containing biomolecules, etc. The interaction modes (intercalating, electrostatic interaction, covalent bonding, etc.) are focused to illustrate the reason for the antitumor activity of Au complexes.
