9-aminonoscapine, prodrugs thereof, and pharmaceutically acceptable salts thereof, are disclosed. Pharmaceutical compositions including 9-aminonoscapine, and methods of preparation and use thereof are disclosed. 9-aminonoscapine is a noscapine analog that can be used to treat and/or prevent a wide variety of cancers, including drug resistant cancers, by binding tubulin and inducing apoptosis selectively in tumor cells (ovarian and T-cell lymphoma) resistant to paclitaxel, vinblastine and teniposide. 9-aminonoscapine can perturb the progression of cell cycle by mitotic arrest, followed by apoptotic cell death associated with increased caspase-3 activation and appearance of TUNEL-positive cells. Thus, 9-aminonoscapine is a novel therapeutic agents for a variety of cancers, including ovarian and T-cell lymphoma cancers, even those that have become drug-resistant to currently available chemotherapeutic drugs.
9-氨基诺斯卡平,其前药物以及其药用盐已被披露。包括9-氨基诺斯卡平的药物组合物,以及其制备和使用方法也已被披露。9-氨基诺斯卡平是一种诺斯卡平类似物,可用于治疗和/或预防各种癌症,包括对紫杉醇、长春新碱和替尼泊苷耐药的癌细胞(卵巢和T细胞淋巴瘤),通过结合微管蛋白并选择性诱导肿瘤细胞凋亡。9-氨基诺斯卡平可以通过有丝分裂阻滞扰乱细胞周期的进展,随后伴随着增加的caspase-3激活和TUNEL阳性细胞的出现而导致细胞凋亡。因此,9-氨基诺斯卡平是一种新型的治疗剂,可用于治疗各种癌症,包括卵巢和T细胞淋巴瘤癌,甚至那些已对当前可用的化疗药物产生耐药性的癌症。
