Fidaxomicin is a novel macrolide antibiotic used in the treatment of diarrhea caused by _Clostridioides_ (formerly _Clostridium_) _difficile_ in adult and pediatric patients over the age of 6 months. Fidaxomicin is a naturally-occurring 18-member macrocycle derived from fermentation. Because fidaxomicin contains an 18-membered lactone ring in its structure, it is referred to as a macrocyclic lactone antibiotic drug. The antibacterial activity of fidaxomicin is distinct from macrolides and rifamycins, as the bactericidal activity is time-dependent, and not concentration-dependent. Fidaxomicin was the first macrocyclic lactone antibiotic with activity against _C. difficile_, and it displays a narrow spectrum of activity against gram-positive anaerobes. It mediates its potent bactericidal action on the bacteria by inhibiting the bacterial RNA synthase
Istradefylline, or KW6002, was developed by Kyowa Hakko Kirin in Japan for the treatment of Parkinson's disease as an adjunct to standard therapy. Unlike standard dopaminergic therapies for Parkinson's, Istradefylline targets adenosine A<sub>2A</sub> receptors in the basal ganglia. This region of the brain is highly involved in motor control. Istradefylline is indicated as an adjunct treatment to [levodopa] and [carbidopa] for Parkinson's disease. This drug was first approved in Japan on 25 March 2013. Istradefylline was granted FDA approval on 27 August 2019.
