Anidulafungin (brand names Eraxis (in U.S. and Russia) and Ecalta (in Europe)) is a semi-synthetic echinocandin with antifungal activity and it is active in vitro against many Candida, as well as some Aspergillus. Like other echinocandins, anidulafungin is not active against Cryptococcus neoformans, Trichosporon, Fusarium, or zygomycetes. This drug is indicated for the treatment of candidemia and the following Candida infections: intra-abdominal abscess and peritonitis; and for the treatment of esophageal candidiasis. Anidulafungin inhibits glucan synthase, an enzyme present in fungal, but not mammalian cells. This results in inhibition of the formation of 1,3--D-glucan, an essential component of the fungal cell wall.

Caspofungin is an echinocandin antifungal drug, which is approved and is sold under the brand worldwide name cancidas. Caspofungin inhibits the synthesis of beta (1,3)-D-glucan, an essential component of the cell wall of susceptible Aspergillus species and Candida species. Beta (1,3)-D-glucan is not present in mammalian cells. Cancidas is indicated for the treatment of candidemia and the following candida infections: intra-abdominal abscesses, peritonitis, and pleural space infections in adult and pediatric patients. Also is indicated for the treatment of esophageal candidiasis in adult and pediatric patients and for the treatment of invasive aspergillosis in adult and pediatric patients, but has not been studied as initial therapy for invasive aspergillosis.
