WebApr 11, 2024 · Echinocandin B is a natural product that possesses potent antifungal property against a wide array of fungi. This antifungal agent is produced by Emericella rugulosa. The biosynth Echinocandins are a class of antifungal drugs that inhibit the synthesis of β-glucan in the fungal cell wall via noncompetitive inhibition of the enzyme 1,3-β glucan synthase. The class has been termed the "penicillin of antifungals," along with the related papulacandins, as their mechanism of action resembles that of penicillin in bacteria. β-glucans are carbohydrate polymers that are cross-linke…
