摘要
化学武器作为全球威胁在恐怖组织手中的重新出现,再加上在世界范围内越来越多的农药中毒和环境污染,引起了科学界为解毒有机磷化合物(OP)在技术提高的需要的关注。一个引人注目的战略是通过酶能水解这些分子到无害的化学物种的生物修复的应用。几种酶已被研究和设计用于此目的。然而,他们的行动机制还不清楚。理论研究可能有助于阐明这些机制的重要方面,并且有助于开发更有效的生物修复剂。在这篇综述中,我们指出适用于解毒有机磷化合物为基础的酶的计算方法主要贡献。此外,我们强调手提式测试装置,无源光网络,数字平板的使用,和丁酰胆碱酯酶作为有机磷化合物解毒过程的酶和如何计算工具如分子对接,分子动力学模拟,以及结合量子力学/分子力学已经并将继续致力于这项重要的研究领域。

摘要: The re-emergence of chemical weapons as a global threat in hands of terrorist groups, together with an increasing number of pesticides intoxications and environmental contaminations worldwide, has called the attention of the scientific community for the need of improvement in the technologies for detoxification of organophosphorus (OP) compounds. A compelling strategy is the use of bioremediation by enzymes that are able to hydrolyze these molecules to harmless chemical species. Several enzymes have been studied and engineered for this purpose. However, their mechanisms of action are not well understood. Theoretical investigations may help elucidate important aspects of these mechanisms and help in the development of more efficient bio-remediators. In this review, we point out the major contributions of computational methodologies applied to enzyme based detoxification of OPs. Furthermore, we highlight the use of PTE, PON, DFP, and BuChE as enzymes used in OP detoxification process and how computational tools such as molecular docking, molecular dynamics simulations and combined quantum mechanical/molecular mechanics have and will continue to contribute to this very important area of research.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
