Ampullosporin (I; Ac-Trp-Ala-Aib-Aib-Leu-Aib-Gln-Aib-Aib-Aib-Gln-Leu-Aib-Gln-Leuol) was isolated from the mycelium of Sepedonium ampullosporum as a new 15-membered peptaibol-type antibiotic. The structure was determined by mass spectrometric and two-dimensional NMR experiments. Ampullosporin displays narrow-spectrum antibacterial and antifungal activity, induces pigment formation by Phoma destructiva, causes hypothermia and decreased spontaneous locomotor activity in mice in dosages > 1 mg/kg.
壶孢菌素(I;Ac-Trp-Ala-Aib-Aib-Leu-Aib-Gln-Aib-Aib-Aib-Gln-Leu-Aib-Gln-Leuol)是从壶孢菌的菌丝体中分离得到的一种新型15元肽菌素类抗生素。其结构通过质谱和二维核磁共振实验确定。壶孢菌素具有窄谱抗菌和抗真菌活性,能诱导毁灭茎点霉形成色素,在剂量>1mg/kg时可导致小鼠体温过低和自发运动活动减少。
