solution-phase synthesis of distamycin A and its extension to the preparation of 2640 analogues are described. Thus, solution-phase synthesis techniques with reaction workup and purification employing acid/base liquid−liquid extractions were used in the multistep preparation of distamycin A (8 steps, 40% overall yield) and a prototypical library of 2640 analogues providing intermediates and final products that
描述了远霉素 A 的液相合成的发展及其对 2640 类似物制备的扩展。因此,采用酸/碱液-液萃取进行反应后处理和纯化的液相合成技术用于多步制备偏霉素 A(8 步,40% 总产率)和 2640 类似物的原型库,提供中间体和最终产品在常规反应规模上纯度≥95%。公开了一种简单、快速和高通量的 DNA 结合亲和力筛选的补充开发,该筛选基于来自预结合溴化乙锭置换的荧光损失,适用于评估对 DNA 均聚物或特定序列的相对或绝对结合亲和力。发夹寡核苷酸)。使用发夹寡核苷酸,
