Traditionally,
small molecule drugs have been derived from natural products (plants,
microbes, and marine organisms). With the explosion of genetic
information, the creation of nucleic-acid-based therapeutics is now
advancing at a rapid pace. These so-called gene therapies translate
knowledge acquired on the genetic bases of diseases into treatments for
humans. Unlike small molecule drugs that can passively move into and
throughout cells, macromolecular therapeutics must actively be
transported. With nucleic-acid-based drugs, the active transport
involves penetration into the cell and movement to the nucleus. These
demands take drug delivery to new heights by now requiring not only
control of the level and location of the drug within the body, but also
intracellular trafficking to a specified sub-cellular locality
(nucleus). Efforts to design and prepare new synthetic materials for
gene delivery are increasing, and an example highlighting the use of
intelligent materials will be presented. |
