When Telegraph UK published the article, “Scientists find drug to banish bad memories” the piece was dugg over 1200 times. The article title effectively hypes up the idea that is currently backed up only by the most preliminary experiments. The truth in application remains years away – if indeed application of this idea is possible. That’s because many early scientific experiments of interesting chemicals working in mice and rats are hyped up by the press or by scientists themselves who can benefit from the publicity (translation: potential for future research funding).
What is not emphasized enough for the public is that what may look interesting in petri dishes or lab mice / lab rats remain just that – interesting. Does this interesting result translates to something actually happening in humans? Not always. Still it makes for good sci-fi movies or even a sequel to Eternal Sunshine of the Spotless Mind.
So what exactly is U0126? According to the Promega (a chemical supply company) website: U0126 is a synthetic chemical MEK Inhibitor that blocks the activity of the MAP (mitogen activated protein) kinase kinase (not a duplicate typo), MEK. U0126 is more potent and less toxic than PD098059, another MEK inhibitor that has been under investigation for potential therapeutic use for decades, but hasn’t resulted in a human application.
