Echinocandin mechanism of action
WebThe echinocandin antifungals, ... The echinocandins are lipopeptide antifungals that inhibit the formation of β-1,3-d-glucans in the fungal cell wall, a mechanism of action that is completely different from that for AMB and the azoles. The prototype drug is caspofungin acetate (Cancidas). Other drugs in this class are micafungin and anidulafungin. WebBecause of the differences in the mechanisms of action and known mechanisms of resistance, the exact cause of azole and echinocandin coresistance in some C. glabrata isolates is unknown. As many patients with invasive candidiasis due to C. glabrata have multiple comorbidities, previous exposure to these antifungal classes may also play a role.

Echinocandins noncompetitively inhibit beta-1,3-D-glucan synthase enzyme complex in susceptible fungi to disturb fungal cell glucan synthesis. Beta-glucan destruction prevents resistance against osmotic forces, which leads to cell lysis. They have fungistatic activity against Aspergillus species. and fungicidal activity against most Candida spp., including strains that are resistant to fluconazole. In vitro and mouse models show echinocandins may also enhance hos… WebMicafungin, an echinocandin antifungal agent with a novel mechanism of action, inhibits beta-(1,3)-D-glucan synthase interfering with fungal cell wall synthesis. It shows excellent antifungal activity against a broad range of Candida spp., including azole-resistant strains, and Aspergillus spp. in in vitro and animal studies.
