Abstract

Disclosed are compositions and methods for antimicrobial use. The compositions contain a small antimicrobial agent and a permeabilizing agent. The antimicrobial compositions can be antifungal or antibacterial compositions.

Claims (31)

1. An antimicrobial composition comprising an effective amount of a small antimicrobial agent in combination with an effective amount of one or more further agents, wherein the small antimicrobial agent and the one or more further agents are together effective to reduce growth or viability of microbial cells, wherein the one or more further agents comprise a first antimicrobial agent,

wherein the one or more further agents increase the cellular uptake, retention, or both, of the small antimicrobial agent in the microbial cells, wherein the first antimicrobial agent increases the retention of the small antimicrobial agent,

wherein the reduction in growth or viability of the microbial cells is more than the additive reduction achieved by using each agent alone,

wherein the first antimicrobial agent has the structure

2. The composition of claim 1 , wherein the small antimicrobial agent is a small antifungal agent.

3. The composition of claim 1 , wherein the small antimicrobial agent is an anion or a pharmaceutically acceptable salt thereof.

4. The composition of claim 1 , wherein the small antimicrobial agent is selected from the group consisting of fluoride, chloride, bromide, and iodine.

5. The composition of claim 1 , wherein the small antimicrobial agent is selected from the group consisting of fluoride salts, chloride salts, bromide salts, and iodine salts.

6. The composition of claim 1 , wherein the small antimicrobial agent is fluoride or a pharmaceutically acceptable salt thereof.

7. The composition of claim 1 further comprising a carrier, wherein the carrier comprises a cream, paste, fluid, coating, paint, spray, detergent, or a combination.

8. The composition of claim 1 further comprising a carrier, wherein the carrier comprises antimicrobial cream, antimicrobial paste, antimicrobial fluid, antimicrobial coating, antimicrobial paint, antimicrobial spray, antimicrobial detergent, antimicrobial soap, mouthwash, skinwash, nasal wash, toothpaste, toothwash, dish detergent, laundry detergent, dishwasher detergent, nasal spray, mouth spray, throat spray, skin spray, douche fluid, enema fluid, wound cleanser, wound covering, eyewash, shampoo, facial wash, facial cream, or facial soap.

9. A method of treating a microbial condition comprising, administering to a subject in need thereof the composition of claim 1 in an amount effective to reduce growth or viability of microbial cells.

10. The method of claim 9 , wherein the small antimicrobial agent is an antifungal agent.

11. The method of claim 9 , wherein the small antimicrobial agent is an anion or a pharmaceutically acceptable salt thereof.

12. The method of claim 9 , wherein the small antimicrobial agent is selected from the group consisting of fluoride, chloride, bromide, iodine.

13. The method of claim 9 , wherein the small antimicrobial agent is selected from the group consisting of fluoride salts, chloride salts, bromide salts, and iodine salts.

14. The method of claim 9 , wherein the small antimicrobial agent is fluoride or a salt thereof.

15. The method of claim 9 , wherein the composition is administered as a cream, paste, fluid, coating, paint, spray, detergent, or a combination.

16. The method of claim 9 , wherein the one or more further agents further comprise a permeabilizing agent, wherein the permeabilizing agent increases the cellular uptake of the small antimicrobial agent.

17. The method of claim 16 , wherein the permeabilizing agent is not an ion channel-forming peptide or protein.

18. The method of claim 16 , wherein the permeabilizing agent is a polyene macrolide or NP213.

19. The method of claim 18 , wherein the polyene is selected from the group consisting of amphotericin B, amphotericin B deoxycholate, liposomal amphotericin B, amphotericin B lipid complex, amphotec, candidin, candidoin, candidinin, mycoheptin, nystatin, polyfungin, aureofacin, vacidin, trichomycin, candicidin, and pimaricin.

20. The method of claim 19 , wherein the polyene is amphotericin B.

21. An antimicrobial composition comprising an effective amount of a small antimicrobial agent in combination with an effective amount of a permeabilizing agent and an effective amount of a first antimicrobial agent, wherein the small antimicrobial agent, the permeabilizing agent, and the first antimicrobial agents are together effective to reduce growth or viability of microbial cells,

wherein the permeabilizing agent increases the cellular uptake of the small antimicrobial agent, wherein the first antimicrobial agent increases the retention of the small antimicrobial agent,

wherein reduction in microbial growth or viability is more than the additive reduction achieved by using each agent alone, and

wherein the first antimicrobial agent has the structure

22. The composition of claim 21 , wherein the permeabilizing agent is a polyene macrolide or NP213.

23. The composition of claim 22 , wherein the polyene is selected from the group consisting of amphotericin B, amphotericin B deoxycholate, liposomal amphotericin B, amphotericin B lipid complex, amphotec candidin, candidoin, candidinin, mycoheptin, nystatin, polyfungin, aureofacin, vacidin, trichomycin, candicidin, and pimaricin.

24. The composition of claim 23 , wherein the polyene is amphotericin B.

25. A method of treating a microbial condition comprising, administering to a subject in need thereof the composition according to claim 21 .
