Echinoctin B is a naturally occurring circular hexapeptide with acyl side chains. It belongs to a class of antifungal drugs called echinoctin, and is a major component of fungal cell wall glucan synthesis by noncompetitive inhibition of a key enzyme β- (1,3) -d-glucan synthase.

Echinocandin B is a cyclic hexapeptide echinocandin antibiotic. It is the major component to inhibits the synthesis of fungal cell wall glucan, by non-competitive inhibition of a key enzyme β-(1,3)-D-glucan synthase
