Zongbin Wu¹|Peng Tian^2**|Zhongmin Liu²,Zongqiang Mao¹. Progress in Porous Phosphonates[J]. Progress in Chemistry, 2006, 18(09): 1092-1100.

Porous phosphonates are novel porous materials , which have drawn much attention in recent years. The derivable and variety of organophosphorus ligands endow the materials many special properties. The synthetic methods and their characters have been discussed. Precipitation method , melt method , hydrothermal method , solvothermal method ,and template-assisted method have been developed for synthesizing porous phosphonates. Following the principles of coordinate chemistry , these methods give many opportunities for synthesizing a desired structure. Besides the well-known pillared-layered structures and zeolite-type structures , novel tubular morphologies with layered frameworks have been reported recently in some diphosphonates. The tubular morphologies open a new strategy for obtaining porous phosphonates. Up to now , great efforts have been devoted to the porous phosphonates , however , only a few of these compounds are really porous. The removal of the template often leads to the collapse of the structures , which hinders the materials for going further. More works and new ideas should been applied to suppress their drawbacks. Some proposals concerning the key points for porous phosphonates have been presented in the article.

Chemical structures and properties of diazeniumdiolates that make them so excellent for designing materials capable of targeting reliable and controllable fluxes of bioactive NO have become one of the forefronts and highlights of novel NO donors. The toxicity and poor biocompatibility of the nucleophile (polyamines) and the formation of potentially carcinogenic nitrosoamine are the problems associated with its successful clinical application. Recent research progress on targeting nitric oxide releasing materials is reviewed , basing on the three strategies of delivering NO specifically to a targeted site , including polymer-based diazeniumdiolates , enzyme activated diazeniumdiolates and photosensitive diazeniumdiolates.

Chloroperoxidase (CPO) as a member of peroxidase family has extensive catalytic activities for various organic substrates. Applications of CPO in organic synthesis has been and will still be a research hotspot , since it was discovered in 1960s. However , the most interest characteristic of the CPO is the chiral catalytic activity performed in the asymmetric synthesis which is related to its unique structure. CPO as a biocatalyst for wide range of substrates to chiral compounds with high yield and enantioselectivity has been studied. In this paper, applications of chloroperoxidase in chiral organic synthesis are introduced. The focuses are especially on halogenation , oxidation of alcohols , hydroxylation , epoxidation and sulfoxidation reactions. The problems faced and the developing trend are also discussed.

Haihua Song^*,Jing Song. The Application of Computer－Aided Molecular Design in Selecting Solvents for Extractive Distillation[J]. Progress in Chemistry, 2006, 18(09): 1188-1193.

Extractive distillation is an important and useful technique for separating close boiling and azeotropic liquid mixtures. The selection of appropriate solvents for extractive distillation is the key to improve the production capacity and reduce the energy consumption. Computer-aided molecular design (CAMD) is on the basis of property estimate method , generating a set of solvent molecular structures with desirable properties and screening the candidate molecules. There are three main CAMD approaches : generation-and-test , mathematical optimization , and combinatorial optimizations. The generation-and-test usually implements heuristics or knowledge-based methods to combat combinatorial explosion of group combinations , can't guarantee the quality of the results. The mathematical optimization approach ,which includes MINLP (mixed-integer nonlinear programming) and MILP (mixed-integer linear programming) problems ,has been applied to the nonlinear or linear structure-property correlations , but exact expression of the structure-property correlations may be very difficult or even impossible. Thus , the third approach , combinatorial optimization such as genetic algorithm(GA) and simulated annealing (SA) , is implemented in CAMD and can easily handle combinatorial complexity of the molecular design. In this paper , the principle of three approaches is depicted , and a comparison among three approaches is made. Furthermore , the major encounter problems in the industrialization of the selection of solvents are also discussed.

Chaofeng Zhang,Huizhi Du,Pin Yang^**. Ion Channel Hypothesis for Molecular Mechanism of Alzheimer's Disease[J]. Progress in Chemistry, 2006, 18(09): 1194-1199.

Although many evidences point to Aβ peptides as playing a key role in pathogenesis of Alzheimer’s disease (AD) , no toxic mechanism has yet been demonstrated. The channel hypothesis of AD proposes that the Aβ peptides which accumulate in plaques in the brain actually damage or kill neurons by forming ion channels. The ability of Aβpeptides to form these Aβ channels and the disruption of calcium homeostasis due to their formation could be the molecular mechanism of the neurotoxicity of Aβ. The evidence for the channel hypothesis of Aβ neurotoxicity are reviewed and the emphasis is on the center role of Cu²⁺ and Zn²⁺ in AD.
