The art of using chemical agents for medication dates back into
antiquity, although most of the earliest examples used plants,
herbs, and other natural materials. The old Egyptian medical
papyri, which date from before 1400 B. C., contain dozens of
examples of such medicinal plants and animal extracts. In the Old
Testament of the Bible, we can find references to using oil to
soften the skin and sores (Isaiah 1:6), the use of tree leaves for
medicine (Ezekiel 47:12) and various medical balms (Jeremiah 8:22).
Not all these recipes were effective in curing the ailments for
which they were used and sometimes the treatment was worse than the
disease. Nevertheless, the art of using chemical derived agents for
medicines continued to develop and received great impetus during
the present century with the rise of synthetic organic chemistry.
One of the most vexing problems has always been to achieve
specifici ty with the medications. While some medical agents do
indeed possess a relatively high degree of specificity, most agents
are far more systemic than would be desired. Much of the research
efforts to correct this deficiency has centered on modifying the
chemical agents themselves. Unfortunately, there are severe
limitations in this approach since minor modifications often
drastically affect the therapeutic activity and can even render the
drug completely ineffective, or worse."
