WebAntibacterial lipopeptides and methods for their preparation and use转让专利转让专利 Echinocandin B, a lipopeptide, is a naturally occurring cyclic hexapeptide with a linoleoyl side chain. It belongs to a class of antifungal agents called echinocandins, which inhibits the synthesis of glucan, a major component of the fungal cell wall, via noncompetitive inhibition of a crucial enzyme, β-(1→3)-D-glucan synthase. Echinocandin B is a fermentation product of Aspergillus nidulans and the closely related species, A. rugulosus; discovered in 1974 in A. nidulans var. echinulatus strai…
