There is no existing cure for the common cold. The reason is simple: it is caused by a family of viruses with hundreds of variants, making it nearly impossible to become immune to or vaccinate against all of them. On top of that, the viruses evolve rapidly, meaning they can quickly gain resistance to drugs.
But there may be some new hope. A paper in Nature Chemistry
discusses a new molecule, IMP-1088, that dual inhibits human N-myristoyltransferases NMT1 and NMT2 protein. Viruses 'hijack' NMT from human cells to construct the protein 'shell', or capsid, which protects the virus genome.
