    摘要: Disclosed are hydrophilic polymers such as polysaccharides, including hyaluronic acid of any origin, modified by reaction with epoxy-functional-silicones. Hydrophobic silicon, which contains chemically active groups covalently attach to the backbone of the hydrophilic polymer and gives these new, modified polymers the ability to dissolve hydrophobic compounds including oils, drugs, and vitamins, while maintaining the hydrophilic properties and benefits of the unmodified polymer. With respect to topical applications these polymers substantially increase the stability of formulations and provide for ease of preparation. The properties and advantages of the original polymer are maintained while other properties are augmented, namely the ability to combine with or dissolve hydrophobic and hydrophilic drugs. The products can be used alone or in combination with other substances for various applications including cosmetic, medical, and drug delivery applications. Also disclosed are methods for preparing them.

    摘要: Disclosed are methods of conjugating biologically active substances, particularly, alpha-interferon, with a hyaluronan or a mixture of a hyaluronan with at least one other hydrophilic polymer having a functional group capable of reacting with divinyl sulfone. Also disclosed are stable intermediates formed by partially reacting a hyaluronan with divinyl sulfone and stopping the reaction before completion to leave free, or reactive vinyl groups on the hyaluronan molecule available for conjugation with the biologically active substance.
