  Quaternary salts of 2-[(hydroxyimino)methyl]imidazole. 5. Structure-activity relationships for side-chain nitro-, sulfone-, amino-, and aminosulfonyl-substituted analogs for therapy against anticholinesterase intoxication

  摘要：

  Several quaternary imidazolium oxime derivatives incorporating side chains bearing nitro, sulfone, amino, and aminosulfonyl substituents were prepared and evaluated as treatment therapeutics for anti-AChE intoxication. In vivo test results in the mouse revealed that many of these compounds are highly effective in providing life-saving protection against the extremely toxic cholinesterase inhibitors soman and tabun. Several structure-activity relationships were noted that were characteristic of the side-chain substituent. In vivo test results for additional selected derivatives of some of the more therapeutically active compounds indicated that the quaternary heteroaryl nucleus is essential for activity whereas a nucleophilic moiety (i.e., oxime) is not. In support of previous suspicions, these results afforded additional evidence suggesting that reactivation is not the main mode of antidotal action by the imidazolium oximes. An alternative antidotal mechanism is postulated that is consistent with all data and that involves enzyme protection by the compounds.

  rely on fully synthetic nucleic acids with photocaged nucleobases, limiting application to relatively short synthetic RNAs. Here we report a method to gain photocontrol over RNA by postsynthetic acylation of 2'-hydroxyls with photoprotecting groups. One-step introduction of these groups efficiently blocks hybridization, which is restored after light exposure. Polyacylation (termed cloaking) enables

  RNA 功能的外部光控制已成为研究核酸生物学的有用工具。大多数当前方法依赖于具有光笼化核碱基的全合成核酸，限制了对相对较短的合成 RNA 的应用。在这里，我们报告了一种通过 2'-羟基与光保护基团的合成后酰化来获得对 RNA 的光控制的方法。这些基团的一步引入有效地阻止了杂交，在光照后恢复。多酰化（称为隐形）可以控制锤头状核酶，说明 RNA 催化功能的光学控制。在转录的 237 nt RNA 适配体上使用新方法证明了这种方法在细胞环境中开启 RNA 折叠的效用，并强调了在生物学研究中的应用潜力。
