Tailor-Made Cancer Drugs

Posted by michael on from the needle-and-thread dept.

pmineiro writes "A researcher at Washington University in St. Louis has developed a method for delivering an inactive drug complex into the body, which is only activated by certain messenger RNA sequences. This allows a drug to be selectively activated only in certain cellular contexts, e.g., cancer or HIV infection."

    In the presence of cosmic rays and background radiation, to say nothing of the computer monitors, cellular phones, and irradicated beef that we surround ourselves with every day, these genetic superdrugs could easily mutate. In their new forms, they'd be essentially unstoppable. One stray gramma ray could spell the end of humanity.

    You would make a great B-Movie script writer.
    Unfortunately, virtually nothing you said can be backed up scientifically. Your flaws are these:

    1) How is this drug going to spread? Drugs are molecules, not viruses or bacteria. The drug will simply stay inside the person they give it to.
    2) If this drug *could* spread, how is it going to reproduce itself? Luckily, drugs dont self-divide or mate to reproduce.
    3) Irratiated beef is NOT radioactive, neither are cell phones. Therefore, harmless beef and cell phones will not alter a drug. (Techinically cell phones give off radiation in the form of radio waves, but visible light gives off far more energetic radiation than a cell phone does.)
    4) Gamma rays, computer monitors, and background radiation could only affect a change in the drug in miniscule amounts. Generally, if one drug molecule was hit by a stray gamma ray, it would change one molecular bond, and perhaps mess up the configuration of the molecule. At absolute worst, a single change alter the drug in such a way that it would kill the person using the drug, but that's *extremely* unlikely.

    Personally, I've read the article, and feel this is a pretty good idea. He uses already approved FDA drugs, and just does a better job targeting them.
