Nucleoside chemical compounds, which interact with specific structures of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) are disclosed. The compounds interfere with the activities of telomerase and reverse transcriptase, and are useful as antivirals, antibacterials and anticancer agents. Methods of treating or preventing cancers in patients involving administration of a therapeutically effective amount of a composition having an inhibitor or antagonist of the reverse transcriptases (RTs) expressed in cells of the patients are also disclosed. Method of using nucleoside analogs and other inhibitors of RTs in conjunction with DNA damaging agents such as genotoxic agents or radiation or photodynamic therapy or combinations these for the treatment of various cancers are also disclosed.
本文披露了与脱氧核糖核酸(DNA)或核糖核酸(RNA)的特定结构相互作用的核苷类化合物。这些化合物干扰端粒酶和反转录酶的活性,并且可用作抗病毒、抗菌和抗癌剂。本文还披露了一种治疗或预防患者癌症的方法,包括向患者细胞中表达的反转录酶(RTs)的抑制剂或拮抗剂的组合物的治疗有效量的给药。本文还披露了使用核苷类类似物和其他RTs抑制剂与DNA损伤剂(如基因毒性剂、辐射或光动力疗法)或这些剂的组合物相结合治疗各种癌症的方法。
