This technology uses novel glycosylated steroid derivatives to facilitate the transport of molecules of a second compound across biological membranes. The facilitation is achieved by combining the derivatives with the molecules of interest, either as a conjugate comprising the derivative covalently linked directly or indirectly with the molecule of interest or as an admixture comprising the two main components. In this manner, the molecule of interest, especially those of a therapeutic si gnificance, can better exhibit its activity, whether of a biological, physical or chemical nature. The technology also encompasses novel methods for the efficient synthesis of these derivatives, including their combinations with representative molecules of interest.
