Disclosed are a drug having renal selectivity and a drug carrier for specifically transporting a drug supported thereon to a kidney. A segment structure specifically recognizable in the kidney is utilized. More specifically, since a segment structure represented by formula (I) is kidney-oriented, introduction of a drug into a molecule having the segment structure can provide a renal targeting drug. A compound, which has the segment structure and can support a drug thereon, can be utilized as a drug carrier which can specifically transport a drug supported thereon to the kidney.
A-U-V- (I)
wherein A represents glycosyl, such as glucosyl, mannosyl, or 2-deoxy-glucosyl; U represents O, S, or NH; and V represents an aromatic hydrocarbon or a straight-chain or branched C1-18 aliphatic hydrocarbon.
本发明涉及一种具有肾脏选择性的药物和一种药物载体,用于将支持在其上的药物专门运输到肾脏。利用在肾脏中特别可识别的片段结构。更具体地说,由式(I)表示的片段结构是以肾脏为导向的,将药物引入具有该片段结构的分子中可以提供肾脏靶向药物。具有该片段结构并能支持药物的化合物可用作药物载体,可将支持在其上的药物专门运输到肾脏。其中,A代表糖基,如葡萄糖基、甘露糖基或2-脱氧葡萄糖基;U代表O、S或NH;V代表芳香族碳氢化合物或直链或支链C1-18脂肪族碳氢化合物。
