Photopharmacology, an emerging approach in medicine, involves activating and deactivating drugs with light. Clinicians use the energy of light to change the shape and chemical properties of a drug, resulting in different biological activity.[1] This is done to ultimately achieve control of when and where drugs are active in a reversible manner, and to prevent side effects and exposure to the environment of antibiotics.[2] Switching drugs "on" and "off" is achieved by introducing photoswitches such as azobenzene, spiropyran or diarylethene into the drug. Photopharmalogical drugs with a photoswitch have two different states, which light can toggle between. Since both states have a different structure, the activity of the drug is different, hence the "on" and "off" state of the drug.[3][4] An example is photostatin, which is an inhibitor that can be switched on and off in vivo to optically control microtubule dynamics.[5][6][need quotation to verify]
