通过将基于伪随机珠的适体文库与缀合化学相结合,我们已经创建了下一代适体,X-适体(XA)。几种X配体可以以定向或随机的方式添加到适体中,以进一步增强它们对靶蛋白的结合亲和力。在这里,我们描述了将证明与CD 44-HABD结合的药物(N-乙酰基-2,3-乙酰基-2-脱氧神经氨酸)添加到完整的单硫代骨架取代的适体中,以使其与靶蛋白的结合亲和力增加高达23倍,同时使药物的结合增加100万倍。
By combining pseudo-random bead-based aptamer libraries with conjugation chemistry, we have created next-generation aptamers, X-aptamers (XAs). Several X ligands can be added in a directed or random fashion to the aptamers to further enhance their binding affinities to the target proteins. Here we describe the addition of a drug (N-acetyl-2,3-dehydro-2-deoxyneuraminic acid) demonstrated to bind to CD44-HABD, to a complete monothioate backbone substituted aptamer to increase its binding affinity to the target protein by up to 23-fold, while increasing the drugs’ binding 1-million fold.
