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
Enzalutamide is an androgen receptor (AR) inhibitor for the treatment of castration-resistant prostate cancer (CRPC), both metastatic and non-metastatic. It is a second-generation antiandrogen agent that the FDA approved on August 31, 2012.[L40639, A252667] Although androgen deprivation therapy (ADT) is the first-line treatment of prostate cancer and remission can be achieved, arising resistance is inevitable, becoming castration-resistant prostate cancer. Until recently, docetaxel is the only treatment available for metastatic CRPC; however, AR inhibitors have been developed for more targeted therapy, although first-generation AR inhibitors like bicalutamide did not substantially increase the survival rate. Second-generation such as enzalutamide is more efficacious due to a higher affinity to AR and no partial agonist activity compared to bicalutamide.[A252667,A252642] Due to a favorable pharmacological profile, a phase 1 study of enzalutamide was initiated in July 2007. Compared to the average time of 10 to 15 years for a drug to go from pre-clinical to clinical studies, enzalutamide was developed relatively rapidly.
