antibiotic molecule echinocandin antibiotic Echinocandins are a group of antibiotics, particularly antifungals, that target the target glucan synthase, an enzyme involved in the cell wall biosynthesis of fungi. They typically induce adaptive mechanisms that promote resistance such as heat shock protein 90, cell wall integrity pathway, high osmolarity glycerol pathway, and chitin biosynthesis. The three main echinocandins are caspofungin, micafungin and anidulafungin. antibiotic_resistance ARO:3007496
