WebEchinocandins are a class of antifungals, mainly used to treat infections caused by candida species and aspergillus species. They work by disrupting the formation of the fungal cell wall, leading to cell death. They inhibit eta-1,3-D-glucan synthase, an enzyme necessary for the synthesis of major fungal cell components known as Beta glucans. WebEchinocandins alone do not completely inhibit in vitro growth of Aspergillus fumigatus, but a powerful antifungal effect is seen in combination with phagocytes. Echinocandins enhance neutrophil activity against Aspergillus and non-Aspergillus hyphae by unmasking β-glucans and activating host antifungal pathways via the dectin-1 receptor. 151,152 law on trusts
