Drug promiscuity, a phenomenon where a single drug affects more than one cell population, has always proven to be a problem for drug makers today. While drug promiscuity is a desirable attribute in some diseases conferring multiple abnormalities, it is undesirable for certain diseases such as cancer. To put things into perspective, cancer cells are essentiallyÂ ourÂ cells, at least they derived fromÂ ourÂ cells. They have the same genetic makeup but different epigenetic profiles. As such, it becomes difficult to target them without affecting our healthy cells. So if one uses a potent toxin against cancer, we are essentially putting our healthy cells in the line of fire.
For example, breast cancer patients taking Herceptin together with a toxic chemotherapy agent experience side effects such as hair loss and discolored nails. The New York Times reported that T-DM1, a drug developed from HerceptinÂ linkedÂ to a chemotherapy agent, has shown to eliminate the most of the severe side effects. Such targeted cancer therapy is not only effective in treating cancer, but also eliminates most side effects. This success did not come easy as the linkers were tricky to develop. The linkers needed to keep the toxin attached to the antibody while in the bloodstream, and only release it inside the cancer cells.
