Abstract

A method for treating skin cancer including the steps of applying an isothiocyanate functional surfactant to an area affected by skin cancer, wherein the isothiocyanate functional surfactant comprises at least one isothiocyanate functional group associated with an aliphatic and/or aromatic carbon atom of the isothiocyanate functional surfactant.

Claims (22)

1. A method for treating skin cancer, with a lysine derivative surfactant having an isothiocyanate functional group, comprising the step(s) of:

applying a lysine derivative surfactant to an area affected by skin cancer, wherein the lysine derivative surfactant comprises an alkanoyl substituent containing at least 8 carbon atoms bound to the α-nitrogen of the lysine, and further wherein the ε-nitrogen of the lysine forms part of an isothiocyanate functional group.

2. The method for treating skin cancer according to claim 1 , wherein the skin cancer is selected from one of the groups comprising basal cell carcinoma, squamous cell carcinoma, melanoma, and merkel cell carcinoma.

3. The method for treating skin cancer according to claim 1 , further comprising the step of applying an additional surfactant, wherein the additional surfactant is selected from at least one of the group comprising a non-ionic surfactant, an anionic surfactant, a cationic surfactant, a zwitterionic surfactant, and combinations thereof.

4. The method for treating skin cancer according to claim 1 , further comprising the step of applying an additional surfactant, wherein the additional surfactant comprises a non-ionic surfactant.

5. The method for treating skin cancer according to claim 4 , wherein the non-ionic surfactant is selected from at least one of the group comprising alcohols, alkanolamides, amine oxides, esters, glycerides, ethoxylated glycerides, polyglyceryl esters, sorbitan esters, carbohydrate esters, ethoxylated carboxylic acids, phosphoric acid triesters, ethers, ethoxylated alcohols, alkyl glucosides, ethoxylated polypropylene oxide ethers, alkylated polyethylene oxides, alkylated polypropylene oxides, alkylated PEG/PPO copolymers, and combinations thereof.

6. The method for treating skin cancer according to claim 1 , further comprising the step of applying an additional surfactant, wherein the additional surfactant comprises an anionic surfactant.

7. The method for treating skin cancer according to claim 6 , wherein the anionic surfactant is selected from at least one of the group comprising taurates, isethionates, alkyl sulfates, alkyl ether sulfates, succinamates, alkyl sulfonates, alkylaryl sulfonates, olefin sulfonates, alkoxy alkane sulfonates, salts of fatty acids derived from natural plant and/ or animal sources and/or synthetically prepared, alkylated ammonium salts of alkylated and/or acylated amino acids and/or peptides, alkylated sulfoacetates, alkylated sulfosuccinates, acylglyceride sulfonates, alkoxyether sulfonates, phosphoric acid esters, phospholipids, and combinations thereof.

8. The method for treating skin cancer according to claim 1 , further comprising the step of applying an additional surfactant, wherein the additional surfactant comprises a cationic surfactant.

9. The method for treating skin cancer according to claim 8 , wherein the cationic surfactant is selected from at least one of the group comprising alkylated quaternary ammonium salts R 4 NX, alkylated amino-amides (RCONH—(CH 2 ) n )NR 3 X, alkylimidazolines, alkoxylated amines, and combinations thereof.

10. The method for treating skin cancer according to claim 1 , further comprising the step of applying an additional surfactant, wherein the additional surfactant comprises a zwitterionic surfactant.

11. The method for treating skin cancer according to claim 10 , wherein the zwitterionic surfactant is selected from at least one of the group comprising betaines, sultaines, hydroxysultaines, amido betaines, amidosulfo betaines, and combinations thereof.

12. A method for treating skin cancer, with a lysine derivative surfactant having an isothiocyanate functional group, comprising the step(s) of:

administering a lysine derivative surfactant to a patient having skin cancer, wherein the lysine derivative surfactant comprises an alkanoyl substituent containing at least 8 carbon atoms bound to the α-nitrogen of the lysine, and further wherein the ε-nitrogen of the lysine forms part of an isothiocyanate functional group.

13. The method for treating skin cancer according to claim 12 , wherein the skin cancer is selected from one of the groups comprising basal cell carcinoma, squamous cell carcinoma, melanoma, and merkel cell carcinoma.

14. The method for treating skin cancer according to claim 12 , further comprising the step of administering an additional surfactant, wherein the additional surfactant is selected from at least one of the group comprising a non-ionic surfactant, an anionic surfactant, a cationic surfactant, a zwitterionic surfactant, and combinations thereof.

15. The method for treating skin cancer according to claim 12 , further comprising the step of administering an additional surfactant, wherein the additional surfactant comprises a non-ionic surfactant.

16. The method for treating skin cancer according to claim 15 , wherein the non-ionic surfactant is selected from at least one of the group comprising alcohols, alkanolamides, amine oxides, esters, glycerides, ethoxylated glycerides, polyglyceryl esters, sorbitan esters, carbohydrate esters, ethoxylated carboxylic acids, phosphoric acid triesters, ethers, ethoxylated alcohols, alkyl glucosides, ethoxylated polypropylene oxide ethers, alkylated polyethylene oxides, alkylated polypropylene oxides, alkylated PEG/PPO copolymers, and combinations thereof.

17. The method for treating skin cancer according to claim 12 , further comprising the step of administering an additional surfactant, wherein the additional surfactant comprises an anionic surfactant.

18. The method for treating skin cancer according to claim 17 , wherein the anionic surfactant is selected from at least one of the group comprising taurates, isethionates, alkyl sulfates, alkyl ether sulfates, succinamates, alkyl sulfonates, alkylaryl sulfonates, olefin sulfonates, alkoxy alkane sulfonates, salts of fatty acids derived from natural plant and/ or animal sources and/or synthetically prepared, alkylated ammonium salts of alkylated and/or acylated amino acids and/or peptides, alkylated sulfoacetates, alkylated sulfosuccinates, acylglyceride sulfonates, alkoxyether sulfonates, phosphoric acid esters, phospholipids, and combinations thereof.

19. The method for treating skin cancer according to claim 12 , further comprising the step of administering an additional surfactant, wherein the additional surfactant comprises a cationic surfactant.

20. The method for treating skin cancer according to claim 19 , wherein the cationic surfactant is selected from at least one of the group comprising alkylated quaternary ammonium salts R 4 NX, alkylated amino-amides (RCONH—(CH 2 ) n )NR 3 X, alkylimidazolines, alkoxylated amines, and combinations thereof.
