Title:	Compositions and methods for enhancing penetration of biologically active substances into tissues or organs
Abstract:	According to this invention, compositions and methods for increasing the extent of penetration of a biologically active substance into the tissues and organs are proposed, the methods comprising administration of the biologically active substance in combination with one or more chaotropic agents, e.g., ammonium sulfate.
Inventor(s):	Klimova; Olga (Moscow, RU)
Assignee:	Joint-stock company \"High Tech\" (Saint-Petersburg, RU)
Application Number:	13/857,735
Patent Claims:	1. A method for increasing permeability of dermal tissue or mucosal tissue to at least one biologically active agent in a subject in need thereof, the method comprising contacting said dermal tissue or said mucosal tissue with an effective amount of the at least one biologically active agent in combination with a composition comprising ammonium sulfate, such that said permeability is increased; wherein penetration by said biologically active agent of said dermal tissue or said mucosal tissue occurs by passive diffusion and wherein the concentration of ammonium sulfate in the composition is between 0.1 M and 1 M. 2. A method of transdermally or transmucosally treating with at least one biologically active agent a subject in need of treatment with the at least one biologically active agent, the method comprising contacting dermal or mucosal tissue of said subject with at least one biologically active agent in combination with a composition comprising ammonium sulfate, such that said subject is treated; wherein penetration by said biologically active agent of said dermal tissue or said mucosal tissue occurs by passive diffusion and wherein the concentration of ammonium sulfate in the composition is between 0.1 M and 1 M. 3. The method of claim 1 or 2, wherein the biologically active agent is a biopolymer. 4. The method of claim 3, wherein the biologically active agent is an oligonucleotide, a protein, a peptide or an enzyme. 5. The method of claim 1 or 2, wherein the subject has diabetes and the biologically active agent is insulin. 6. The method of claim 1 or 2, wherein the subject has a skin wound or a scar and the biologically active agent is a proteolytic enzyme. 7. The method of claim 6, wherein the proteolytic enzyme is collagenase. 8. The method of claim 7, wherein the collagenase is represented by a complex of collagenolytic digestive proteases from hydrobionts. 9. The method of claim 6, wherein the skin wound or a scar results from a surgery, a burn, a frostbite, or acne. 10. The method of claim 1 or 2, wherein the dermal tissue is skin. 11. The method of claim 1 or 2, wherein the mucosal tissue is buccal tissue. 12. The method of claim 4, wherein the biologically active agent is superoxide dismutase. 13. The method of claim 1 or 2, wherein the one or more biologically active agent in combination with a composition comprising ammonium sulfate is administered dermally, bucally, sublingually, transmucosally, rectally, urethrally, vaginally, orally, instillationally or by inhalation. 14. The method of claim 13, wherein the one or more biologically active agent in combination with a composition comprising ammonium sulfate is administered orally in the form of a tablet, a capsule or a pellet. 15. The method of claim 13, wherein the one or more biologically active agent in combination with a composition comprising ammonium sulfate is administered topically in the form of a gel, an ointment, a liniment, a lotion, a cream, a pill, a powder, a suspension, an emulsion or a suppository. 16. The method of claim 13, wherein the one or more biologically active agent in combination with a composition comprising ammonium sulfate is administered by an intradermal injection. 17. The method of claim 1 or 2, wherein the one or more biologically active agent is used for mesotherapy and is a vitamin, a hormone, an amino acid or a hyaluronic acid.
