This invention provides compositions and methods for enhancing delivery of drugs and other agents across epithelial tissues, including into and across ocular tissues and the like. The compositions and methods are also useful for delivery across endothelial tissues, including the blood brain barrier. The compositions and methods employ a delivery enhancing transporter that has sufficient guanidino or amidino sidechain moieties to enhance delivery of a compound conjugated to the reagent across one or more layers of the tissue, compared to the non-conjugated compound. The delivery-enhancing polymers include, for example, poly-arginine molecules that are preferably between about 6 and 25 residues in length.
这项发明提供了增强药物和其他药剂通过上皮组织传递的组合物和方法,包括进入和穿过眼组织等。这些组合物和方法也适用于穿过内皮组织,包括血脑屏障。这些组合物和方法利用了一种具有足够的瓜二或酰胺基侧链基团以增强与试剂结合的化合物穿过组织一层或多层的传递的传递增强转运体,与非结合化合物相比。传递增强聚合物包括,例如,多精氨酸分子,其长度在大约6到25个残基之间。
