    Synthesis of 4′-Ethynyl-2′-deoxy-4′-thioribonucleosides and Discovery of a Highly Potent and Less Toxic NRTI
    摘要:
    The synthesis of 4'-ethynyl-2'-deoxy-4'-thioribonucleosides was carried out utilizing an electrophilic glycosidation in which 4-ethynyl-4-thiofuranoid glycal 16 served as a glycosyl donor. Electrophilic glycosidation between 16 and the silylated nucleobases (N-4-acetylcytosine, N-6-benzoyladenine, and N-2-acetyl-O-6-diphenylcarbamoylguanine) was carried out in the presence of N-iodosuccinimide (NIS), leading to the exclusive formation of the desired beta-anomers 29, 33, and 36. Anti-HIV studies demonstrated that these 4'-thio nucleosides were less cytotoxic to T-lymphocyte (i.e., MT-4 cells) than the corresponding 4'-ethynyl derivatives of 2'-deoxycytidine (44), 2'-deoxyadenosine (45), and 2'-deoxyguanosine (46). Comparison of the selectivity indices (SI) was made between 4'-thionucleosides (32, 41, and 43) and the corresponding 4'-oxygen analogues 44-46 by using the reported CC50 and EC50 values. In the case of cytosine and adenine nucleosides, comparable SI values were obtained as follows: 32 (545) and 44 (458); 41 (>230) and 45 (1630). In contrast, 4'-ethynyl-2'-deoxy-4'-thioguanosine 43 was found to possess a SI value of >18200, which is 20 times better than that of 46 (933).

    发现新模板,7-取代的 7-Deaza-4'-硫腺苷衍生物作为多激酶抑制剂
    摘要:
    由于潜在的耐药性,抗癌药物的开发仍然具有挑战性。同时抑制与癌症有关的多个靶点可以克服耐药性,并且这些药物比单靶点抑制剂表现出更高的效力。蛋白激酶代表了开发抗癌剂的有希望的目标。由于大多数多激酶抑制剂是杂环,仅占据 ATP 结合位点的铰链和疏水区,我们的目标是设计多激酶抑制剂,基于 ATP 激酶相互作用,将占据核糖袋以及铰链和疏水区. 在此,我们报告发现了一种新的 4'-硫代核苷模板,它是一种具有有效抗癌活性的多激酶抑制剂。体外评估显示铅1g(7-乙炔-7-deaza-4'-thioadenosine) 具有有效的抗癌活性,并在激酶组扫描试验中显着抑制 TRKA、CK1δ 和 DYRK1A / 1B 激酶。我们相信这些发现将为开发抗癌药物铺平道路。
