Compounds to combat cold sores

New compounds to fight the herpes simplex virus (HSV-1), which causes cold sores, have been made by researchers from Italy. The compounds' antiviral activity could be enhanced further by encapsulating them in a cyclodextrin nanocarrier that acts as a delivery system. 

Giovanni Grassi and colleagues from the University of Messina made indole-3,4-diones that share structural features with inhibitors of kinase - an enzyme linked to many diseases. The inhibitors were recently reported to prevent viral replication in vitro. 'The diones showed remarkable anti HSV-1 activity in vitro,' says Grassi. They then encapsulated the most effective dione in an amphiphilic - both hydrophilic and lipophilic - cyclodextrin. These nanocarriers increased the ability of the antiviral agents to penetrate into target cells. 

The herpes simplex virus is a DNA virus that can cause a variety of conditions from cold sores through to life threatening diseases. Some strains of the virus have become resistant to the current treatment, aciclovir, so researchers are searching for new treatments. Grassi says that his compounds are highly soluble in organic solvents and water and 'could overcome the limited solubility in water and limited oral bioavailability of aciclovir.'

Indole-3,4-diones were encapsulated in cyclodextrin nanocarriers, increasing their ability to penetrate into target herpes simplex virus cells

'Grassi and colleagues have clearly shown that the cyclodextrins have advantages over unmodified cyclodextrins for cell delivery,' says Raphael Darcy, an expert in cyclodextrins from University College Dublin, Ireland.

'Viral infections are one of the most serious threats to human health,' says Grassi. 'Compared with the number of drugs available to treat bacterial infections, the number of antiviral drugs is small.' This is because of the difficulty in obtaining selective toxicity against viruses and the emergence of drug resistant viral mutants.

'Incorporating an antiviral drug in an engineered nanocarrier is a tool to optimise drug distribution in the body, allowing a specific delivery to the target site and limiting undesired effects,' says Grassi. A future challenge will be to incorporate several bioactive guests into the same nanocarrier. This could lead to therapeutic systems with many functions, he adds, to deliver optimised combinations of conventional drugs for customised medicine.

Butylated Hydroxytoluene also known as BHT works well, especially if it is dissolved first in some oil in the right proportion, such as olive oil, cod-liver oil, vegetable oil etc. and will suppress the herpes virus.

Get them every now and then during the winter. Put regular old Chapstick on them right away (reapply often), gone the next day.

Well windex was a reference to “My big fat greek wedding”, but Real Apple Cider Vinegar (not the filtered clear junk), will cure, and keep away a lot of problems. Braggs, for example, is good ACV.

Since I’ve been taking Vitamin D over the last few winters I haven’t gotten a single cold sore... or a cold for that matter.. and I used to get them alot.

Not lighter fluid, starter fluid. Ether. There is a big difference between the two. Lighter fluid contains naphtha and is irritating to the skin.

When I try to light the starter fluid, the match keeps going out.

I'll take ten gallons of whatever that stuff is that has any hope of fighting any type of herpes

It's expensive but is the best solution I have ever found by far...Abreva! (read the reviews at Amazon link)

I havegood luck with Campho-Phenique, or Carmex if that is not available. Must hit it EARLY.

I have had cold sores since I was a child and have used every remedy known to man.

When I first used Abreva, I was stunned at its effectiveness. I kept applying it (rubbed in little dabs) throughout the first day when I noticed a cold sore starting...Abreva stopped it in its tracks by the next morning. I mean the cold sore was DEAD.

I have NEVER found another remedy that works like that. Most remedies seem to reduce the power of the cold sore (a little), but Abreva killed it.
