The present invention generally relates to tumor homing statin derivatives (THSD) and their use for therapy, in particular cancer therapy. These THSD comprise three moieties: a statin moiety which comprises a dihydroxyheptanoic acid unit (DHHA) fixated by linkage into its open chain form, a heptamethine carbocyanine dye (HMCD) moiety, and a linker that conjugates the DHHA of the statin to the dye moiety. The linker is linked to the DHHA via an ester bond (ester-linked statin derivative or ELSD), or via an amide bond (amide-linked statin derivative or ALSD). Thus linked to the DHHA, the linker provides a relatively stable link either for essentially no hydrolysis/statin release after administration, or preferably for very slow hydrolysis and statin release, as is the case for the ELSD. Embodiments include methods to provide the desired THSD, in particular the ELSD, with the DHHA in its open chain form. The invention also relates to methods wherein one or more ELSD is administered to a patient in a therapeutically effective amount, and methods wherein an ELSD and an ALSD are co-administered in a coordinated administration schedule. Advantages of the THSD and their use include, among others, improved efficacy and dose-response, and decreased statin-associated side effects.
这项发明通常涉及肿瘤靶向他汀衍生物(THSD)及其在治疗中的应用,特别是癌症治疗。这些THSD包括三个部分:他汀部分,其中包括一个由酯键固定在其开链形式中的二羟基庚酸单元(DHHA),一个庚甲基碳氰染料(HMCD)部分,以及将他汀的DHHA与染料部分结合的连接物。连接物通过酯键(酯键结合他汀衍生物或ELSD)或酰胺键(酰胺键结合他汀衍生物或ALSD)与DHHA连接。因此,连接到DHHA的连接物提供了一个相对稳定的连接,要么在给药后基本不发生水解/他汀释放,要么更好地进行非常缓慢的水解和他汀释放,就像ELSD的情况一样。实施例包括提供所需的THSD,特别是ELSD,其中DHHA处于其开链形式。该发明还涉及其中一个或多个ELSD以治疗有效剂量的方式给患者施用的方法,以及其中ELSD和ALSD在协调的给药时间表中联合给药的方法。THSD及其使用的优点包括,但不限于,改善疗效和剂量反应,以及减少与他汀相关的副作用。
