Singly and multiply modified synthetic siRNA oligonucleotides, containing isomorphic surrogate nucleobases, show high interference potency in cell culture, suggesting the highly isomorphic RNA alphabet, based on a thieno[3,4-d]-pyrimidine core, is tolerated well by the cellular silencing machinery.
含有同构替代核碱基的单修饰和多修饰合成小干扰RNA(siRNA)寡核苷酸在细胞培养中显示出高干扰效力,这表明基于噻吩并[3,4-d]嘧啶核心的高度同构RNA字母表能被细胞沉默机制很好地耐受。
