Ethidium bromide has been extended by fusing an additional aromatic ring resulting in a larger intercalator with increased affinity for poly r(A)·r(U), poly d(A)·d(T) and triple helices when compared to the parent heterocycle.
与母杂环相比,
溴化乙啶通过融合一个额外的芳香环得到了扩展,从而产生了一个更大的插加剂,并提高了对聚 r(A)-r(U)、聚 d(A)-d(T)和三重螺旋的亲和力。
