Cyanines which selectively bind to G-quadruplex DNA complexes, particularly quadruplexes expressed in cancer cells, and methods of making and using thereof are described herein. The cyanine can be a symmetrical or unsymmetrical streptocyanine, hemicyanine, closed chain cyanine, or combinations thereof. The cyanine is preferably substituted with one or more groups that minimize or prevent aggregation of the cyanine and/or inhibit binding of the cyanine to duplex DNA. One or more of the cyanines can be formulated with one or more pharmaceutical excipients and/or carrier to prepare pharmaceutical compositions suitable for administration to a patient, particular a human patient. The compounds and compositions described herein can be used to treat diseases or disorders characterized by the expression of G-quadruplex DNA, such as cancer.
本文描述了选择性结合到G-四链体DNA复合物的青菁类化合物,特别是在癌细胞中表达的四链体,以及其制备和使用方法。该青菁类化合物可以是对称或非对称的链青菁、半青菁、闭环青菁,或其组合。该青菁类化合物最好被取代为一个或多个基团,以最小化或防止青菁类化合物的聚集和/或抑制其与双链DNA的结合。其中一个或多个青菁类化合物可以与一个或多个药用辅料和/或载体配制,以制备适合用于患者,特别是人类患者的药物组合物。本文描述的化合物和组合物可用于治疗由G-四链体DNA表达特征的疾病或紊乱,如癌症。
