Three acridine-diaminopurine heterodimers tethered by a linker containing an N,N'-substituted guanidine were prepared. The molecules differ by the site of introduction of the linker on the 2,6-diaminopurine. The interactions of the new heterodimers with abasic site containing oligonucleotide were compared, and their cytotoxicity was measured in the presence or absence of the antitumor alkylating agent
制备了三个由含有N,N′-取代的胍的接头束缚的a啶-二氨基嘌呤异二聚体。分子的不同之处在于接头在2,6-二氨基嘌呤上的引入位点。比较了新的异二聚体与含无碱基位点的寡核苷酸的相互作用,并在有或没有抗肿瘤烷基化剂BCNU的情况下测量了它们的细胞毒性。
