标题:计算和实验分析融合以揭示控制化学反应性的连贯但可延展的适体结构
摘要:作为短核酸,溶液中的适体被认为在结构上是灵活的.与此观点一致,大多数针对此特性进行检查的适体已显示通过可描述为"诱导适合"的机制结合其靶分子.但是,不知道这种结构灵活性在多大程度上影响了目标-适体相互作用的完整性.使用孔雀石绿适体 (Mga) 作为模型系统,我们表明 Mga 可以保护其结合目标孔雀石绿 (Mg) 在几天内免受氧化.保护作用被与 Mga 结合袋互补的寡核苷酸逆转.mga-Mg 结构的计算腔分析预测 Mg 氧化受到保护,因为像 Oh(-) 一样小的分子在空间上被排除在绑定 Mg 的 C1 位置之外.这些结果表明,虽然 Mga-Mg 界面足够连贯以防止 Oh(-) 渗透,但参与相互作用的碱基具有足够的移动性,它们可以交换出 Mg 结合界面以与互补寡核苷酸杂交.使用 Mga 的变体在结合口袋中具有单个碱基变化,通过实验证实了计算预测.这项工作证明了分子动力学模拟和腔分析在确定序

摘要:The object of the present invention are diketopyrrolopyrroles of the general formula (I)wherein, independently of one another, Q1 and Q2 represent an optionally substituted, aromatic, isocyclic or heterocyclic group with 5 to 14 atoms in the ring, the heterocyclic group containing at least one oxygen, nitrogen or sulfur atom, and the R1 and R2 groups, independently of one another represent hydrogen or a Y-B+A- group, with the proviso that at least one of the R1 and R2 groups is not hydrogen; B+ is an aromatic, aliphatic, alicyclic, aromatic heterocyclic or non-aromatic heterocyclic, quaternary ammonium group or a quaternary phosphonium group; Y is an optionally substituted linear or branched C1 to C6 alkylene group and A- is an anion; a method for their synthesis as well as agents, containing compounds of formula (I), for dyeing keratin fibers.
