自旋捕获是一种强大而方便的技术, 自由基反应 其应用范围从临床 研究高能物理。超过1500次引用该技术 在《化学文摘》上积累了很多。 STDBII,自旋捕获 数据库,已在IBM PC/AT和MacIntosh个人计算机上实现 电脑 该软件包没有“附加组件”。“该方案是 功能强大但用户友好;命令结构类似于 熟悉的1-2-3灯条菜单;搜索策略采用 示例查询(QBE);任何字段的逻辑组合都是 使用AND、OR、NOR和EXCEPT完成。 目前,STDBII(4.5) 包含5,5-二甲基-1-吡咯啉-N-氧化物(DMPO)、α-苯基- N-叔丁基硝酮(PBN)、2-甲基-2-亚硝基丙烷(MNP)、α-(4- 吡啶-1-氧化物)-N-叔丁基硝酮(POBN)、亚硝基杜烯(ND)和3,5- 二溴亚硝基苯磺酸盐(DBNBS)。其他不太受欢迎的数据 陷阱被包括在一个全部捕获的文件中。目前,数据库文件 有超过2200个引用,超过9000个参数条目。 的 STDBII文件包含以下信息:1)使用的自旋陷阱; 2)自由基 捕获; 3)报告的超精细分裂; 4)溶剂; 5)g值,如果 报告; 6)如何产生自由基的简洁描述, 观察; 7)完整的书目数据。 最新版本(STDBII,4.5) 还包含自旋捕获率的动力学数据,以及一个新的 参数,NoH值(a/aH的比值),已被证明对 DMPO加合物的鉴定。STDBII帮助研究人员:1)在 从有时独特的超精细中鉴定自旋加合物 分裂参数; 2)作为自旋捕获文献的关键; 3)作为 一种纠正已公布错误的工具。 STDBII现已提供给 NIEHS内外的研究人员。 STDBII计划已 修改,以便用户可以将自己的数据添加到文件中。自旋捕集 数据库现在可以通过互联网访问 (http://lmb.niehs.nih.gov/LMB/mrdb/mrdb.html)。
英文摘要
Spin trapping is a powerful and convenient technique for the study of free radical reactions. The breadth of applications ranges from clinical studies to high-energy physics. Over 1500 references to the technique have accumulated in Chemical Abstracts. STDBII, a spin trapping database, has been implemented on IBM PC/AT and MacIntosh personal computers. The package operates with no "add-ons." The program is powerful yet user-friendly; the command structure is similar to the familiar 1-2-3 light-bar menu; search strategy employs the method of Query-by-Example (QBE); logical combinations of any fields are accomplished by using AND, OR, NOR, and EXCEPT. Presently, STDBII (4.5) contains files for 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), alpha-phenyl- N-tert-butyl nitrone (PBN), 2-methyl-2-nitrosopropane (MNP), alpha-(4- pyridyl-1-oxide)-N-tert-butyl nitrone (POBN), nitrosodurene (ND)and 3,5- dibromo-nitrosobenzene sulfonate (DBNBS). Data for other less popular traps are included in a catch-all file. Presently, the database files have more than 2200 references with over 9000 parameter entries. The STDBII files contain information on: 1) spin trap used; 2) radical trapped; 3) hyperfine splittings reported; 4) solvent; 5) g-value, if reported; 6) a terse description of how the radical was produced and observed; 7) full bibliographic data. The latest version (STDBII, 4.5) also contains kinetic data on spin trapping rates as well as a new parameter, the NoH value (the ratio of a/aH), which has proved useful for the identification of DMPO adducts. STDBII helps researchers: 1) in identification of spin adducts from the sometimes unique hyperfine splitting parameters; 2) as a key to the spin trapping literature 3) as a vehicle to correct published errors. STDBII is now available to researchers both inside and outside NIEHS. The STDBII program has been modified so that users can add their own data to the files. The spin trap database is now accessible via the Internet (http://lmb.niehs.nih.gov/LMB/mrdb/mrdb.html).
