    • Described herein are catechin multimers, and particularly substituted catechin multimers, and their use as carrier moieties for the delivery of nucleophilic and cationic bioactive therapeutic agents to target sites in vivo. For example, substituted catechin multimers of the present invention may be administered alone, for the treatment of stenotic vascular diseases and disorders, such as atherosclerosis (also known as arteriosclerosis) and coronary heart disease (also known as coronary artery disease and ischemic heart disease). Alternatively, catechin multimers, substituted and otherwise, may be complexed with nucleophilic and/or cationic bioactive therapeutic agents, such as anti-thrombotic agents, cholesterol lowering agents, anti-plaque agents, anti-cancer agents, chemotherapeutic agents, anti-inflammatory agents, antibiotics, antimicrobials, wound healing agents, and the like, for the treatment of a variety of diseases and disorders, including but not limited to cardiac and vascular stenoses, cancer, inflammatory conditions, neurological conditions, infection, wounds, burns and the like. The catechin multimers, particularly the substituted catechin multimers, described herein have a strong affinity for polar proteins residing in the vascular endothelium as well as cell walls and membranes, and, accordingly, are able to provide targeted delivery of bioactive agents embedded therein and/or complexed therewith so as to potentiate their therapeutic effects. The therapeutic complexes may be pharmaceutically formulated “neat” (e.g., without additives) or with additives such as pharmaceutical carriers, diluents, buffers, adjuvants, excipients, surfactants, and stabilizers.
    • 本文描述的是儿茶素多聚体,特别是取代的儿茶素多聚体,以及它们作为用于将亲核和阳离子生物活性治疗剂递送到体内靶向部位的载体部分的用途。 例如,本发明的取代儿茶素多聚体可以单独施用,用于治疗狭窄的血管疾病和病症,例如动脉粥样硬化(也称为动脉硬化)和冠心病(也称为冠状动脉疾病和缺血性心脏病) 。 或者,取代或其它方式的儿茶素多聚体可以与亲核和/或阳离子生物活性治疗剂如抗血栓形成剂,胆固醇降低剂,抗斑块剂,抗癌剂,化学治疗剂,抗炎剂 ,抗生素,抗微生物剂,伤口愈合剂等,用于治疗各种疾病和病症,包括但不限于心脏和血管狭窄,癌症,炎性病症,神经病症,感染,伤口,烧伤等 。 本文所述的儿茶素多聚体,特别是取代的儿茶素多聚体对驻留在血管内皮以及细胞壁和膜中的极性蛋白质具有强亲和力,因此能够提供嵌入其中的生物活性剂的靶向递送和/或 与其复合以增强其治疗效果。 治疗复合物可以是药物配制的“纯”(例如,不含添加剂)或添加剂,例如药物载体,稀释剂,缓冲剂,佐剂,赋形剂,表面活性剂和稳定剂。
