Conjugates of biologically active compounds, methods for their preparation and use, formulation and pharmaceutical applications thereof

摘要

This invention features a method of identifying a compound useful for enhancing efficacy of a therapeutic agent. The method includes incubating a compound in blood cells; separating immune cells from erythrocytic cells; and determining the ratio of the concentration of the compound in the immune cells to the concentration of the compound in the erythrocytic cells; wherein the compound comprises a transportophore and a therapeutic agent, in which the transportophore is covalently bonded to the therapeutic agent via a bond or a linker.
