  Compositions and methods for enhancing drug delivery across and into epithelial tissues

  摘要：

  这项发明提供了增强药物和其他药剂跨上皮组织传递的组合物和方法，包括皮肤、胃肠道、肺部上皮、眼部组织等。这些组合物和方法还适用于跨内皮组织传递，包括血脑屏障。这些组合物和方法利用一种传递增强转运体，其具有足够的瓜二胺或酰胺侧链基团，以增强与试剂结合的化合物跨组织的传递，相比未结合的化合物。传递增强聚合物包括例如，首选长度在6到25个残基之间的多精氨酸分子。

  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.

  The present invention provides compositions and methods for enhancing transport of biologically active compounds across biological membranes and across and into animal epithelial or endothelial tissues. The composition includes a biologically active agent and a transport moiety. The transport moiety includes a structure selected from the group consisting of (ZYZ) n Z, (ZY) n Z, (ZYY) n Z and (ZYYY) n Z. Subunit “Z” is L-arginine or D-arginine, and subunit “Y” is an amino acid that does not comprise an amidino or guanidino moiety. Subscript “n” is an integer ranging from 2 to 10. The method for enhancing transport involves the administration of the aforementioned composition.
