Early-stage research has identified a compound that stops pesky colds in their tracks – useful as a potential cold cure. Although adults are bothered by an average of 2-3 colds per year, colds can “cause serious complications in people with conditions like asthma and [chronic obstructive pulmonary disease] (COPD),” lead researcher Edward Tate, Chemical Biology Professor at the Imperial College London, told ScienceDaily. “A drug like this could be extremely beneficial if given early in infection.”

The common cold is caused by many different viruses, with the most common being rhinovirus. Because there are over 100 subtypes of rhinoviruses, it’s hard to develop an effective drug against all of them – one of the reasons there is no cure for a cold yet. Viruses also evolve rapidly, making them hard to effectively target with drugs.

That’s where this compound breaks through – it targets a human enzyme (N-myristoyltransferase) that all rhinoviruses need to survive. Viruses usually hijack the enzyme to help make new copies of themselves. Inhibiting the enzyme and cutting off the virus’ ability to replicate would reduce the virus’ infectivity.

By targeting the human enzyme, a broad-spectrum drug can be made that is harder for the virus to develop resistance to and is effective against all the rhinovirus subtypes. Even better, this compound is effective against viruses in the same family as rhinoviruses, such as poliovirus and hepatitis A virus. The best news? This compound seems to completely prevent viral replication without being toxic when added to human cells before, during, and after viral infection.

But is this compound too good to be true? It has only been tested in human cells in the lab so far, so we don’t know quite yet.

“This is an innovative strategy for combating the common cold, but it may have negative side-effects in humans by inhibiting an important enzyme involved in other cellular processes. However, these side-effects may be a small price to pay for protection for those whose common cold may be life-threatening,” commented Jenna Collier, an Immunology Ph.D. student at Harvard University, who was not involved in this study.

However, this research is in the very early stages, far away from becoming a drug.

Peter Barlow, spokesperson for the British Society for Immunology, who was not involved in this study, told Newsweek, “while this study was conducted entirely in vitro, using cells to model rhinovirus infection in the laboratory, it shows great promise in terms of eventually developing a drug treatment to combat the effects of this virus in patients.”

  1. Hello,
    I am a retired pharmacist. In the year of 2000 I developed a formulation using just nutrients to relieve itch caused by peanut. In the Winter of 2008 I had common cold for 3 days. and so with curiosity to see how anti itching formulation would react on common cold , I took one dosage. three hours later the symptom of common cold such as runny nose sneezing ,coughing and scratch throat were all gone without any side effect. Past 10 years when my wife and I have been using this formulation as soon as I feel symptoms of common cold and stay in warm places, common cold gone within one hour. about a few times it took a few days to cure common cold. I believe I have a common cold curing formulation. Thank you.

  2. So let’s get this right we can map the entire human genome some 3.3 000 000 0 base pairs but we can’t produce drugs to target a few hundred different cold viruses ..
    As normal many areas of medicine are still in the Victorian age with no sign of us leaving this era in the forceable future.

  3. I have a serious suggestion that’s going to sound like a joke… I have successfully cured myself of a cold twice using CS riot control gas. The first time was in Marine Corps boot camp at Parris Island. I was near death on the day of gas mask training. Definitely had a fever. Coughing, sinuses, runny nose, sneezing, etc. I refused to go to the clinic for fear of getting rolled back in training. When I left the gas chamber, I was as healthy as an ox. ZERO cold symptoms from there on out.

    The next time I did it on purpose, to test my theory. I had a bad cold, went to my base gas chamber, and came out a 100% healthy man (several buckets of snot later).

    A quick Google search reveals that I’m not the only person who has experienced this. Perhaps it’s worth studying.
