    摘要: Methods and compositions for transporting drugs and macromolecules across biological membranes are disclosed. In one embodiment, the invention includes a method for enhancing transport of a selected compound across a biological membrane, wherein a biological membrane is contacted with a conjugate containing a biologically active agent that is covalently attached to a transport polymer. In one embodiment, the polymer consists of from 6 to 25 subunits, at least 50% of which contain a guanidino or amidino sidechain moiety. The polymer is effective to impart to the attached agent a rate of trans-membrane transport across a biological membrane that is greater than the rate of trans-membrane transport of the agent in non-conjugated form.

    摘要: 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)nZ, (ZY)nZ, (ZYY)nZ and (ZYYY)nZ. 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.
