Novel generations of antitumor anthraquinones are expected to be advantageous over the conventional chemotherapeutic agents. Previous structure–activityrelationship studies demonstrated an importance of the positively charged side chains conjugated to anthra[2,3-b]thiophene-5,10-dione scaffolds. Exploring a role of individual side chain moieties in binding to the duplex and G-quadruplex DNA, modulation
新一代抗肿瘤蒽醌有望比常规化学治疗剂更具优势。先前的结构-活性关系研究表明,与蒽[2,3 - b ]噻吩-5,10-二酮骨架偶联的带正电荷的侧链非常重要。探索单个侧链部分在与双链体和G-四链体DNA结合,调节端粒酶和拓扑异构酶I活性,细胞内积累和细胞抑制能力方面的作用,我们在本文中分析了一系列报道的和新合成的含蒽的蒽衍生物[ 2,3-乙]噻吩-5,10-二酮。我们发现阳离子侧链的数量(即两个)对于与人端粒G-四链体(TelQ)紧密相互作用至关重要。伴随着较大的药物-TelQ缔合常数,与带有一个碱性基团的类似物相比,在侧链上具有两个碱性基团的蒽噻吩二酮对端粒酶的抑制作用更为明显。对于单胍基化合物,侧链中带有氨基的取代基比甲胺残基具有更好的TelQ亲和力。具有两个侧链的单胍基衍生物的细胞内摄取比双(胍基)衍生物的相应值高> 2倍。这种差异可以解释含有双(胍)化合物的较低的抗增殖能力。因此,蒽的侧链的修饰[2

We have developed an effective method for the synthesis of 4,11-diaminoanthra[2,3-b]furan-5,10-dione and 4,11-diaminoanthra[2,3-b]-thiophene-5,10-dione derivatives based on the substitution of 4,11-alkoxy groups with n-butylamine and subsequent oxidative dealkylation of n-butylamino groups via treatment with tetrabutylammonium hydroxide in DMSO.

A divergent route for the synthesis of new derivatives of 4,11-diaminoanthra[2,3-b]thiophene-5,10-dione was developed based on the introduction of cyclic amines to the terminal positions of 4,11-aminoalkyl groups. Modification of the side chains of anthra[2,3-b]-thiophene-5,10-dione increases the affinity of ligands to DNA duplex and decreases the affinity to G-quadruplexes. An analysis of the structure–activity
基于向4,11-氨基烷基的末端引入环胺,开发了一条合成4,11-二氨基蒽[2,3- b ]噻吩-5,10-二酮新衍生物的途径。蒽侧链的修饰[2,3- b]-噻吩-5,10-二酮增加配体对DNA双链体的亲和力并降低对G-四链体的亲和力。对结构-活性关系的分析表明,2-(哌啶-1-基)乙胺是开发新的双链DNA配体最有希望的侧链片段。新的配体结合DNA双链体的能力与抑制肿瘤细胞的生长有关,这为进一步寻找新的抗肿瘤化合物或化学探针以寻找4,11-二氨基蒽[2,3]中形成双链体的核酸序列的前景。 - b ]噻吩-5,10-二酮。
