Aselacin C is a cyclic pentapeptolide antagonist of endothelin receptor type A (ETA) and ETB originally isolated from Acremonium.1 It inhibits the binding of endothelin-1 to isolated bovine atrial membranes and porcine cerebral membranes, which endogenously express high levels of ETA and ETB, respectively, with IC50 values of 60 and 80 µg/ml, respectively.

Cyclopeptide Derivatives from the Sponge-Derived Fungus Acremonium persicinum F10
Mar Drugs 2021 Sep 24;19(10):537.PMID:34677436DOI:10.3390/md19100537.
Cyclopeptides usually play a pivotal role, either in the viability or virulence of fungi. Two types of cyclopeptides, six new hydroxamate siderophore cyclohexapeptides (1-6), including acremonpeptides E and F, and their complexes with aluminum and ferric ions; one new cyclic pentapeptolide, aselacin D (9); together with a known compound, Aselacin C (10), were isolated and characterized from the sponge-derived fungus Acremonium persicinum F10. In addition, two new siderophore analogues chelating gallium ions (Ga3+), Ga (III)-acremonpeptide E (7) and Ga (III)-acremonpeptide F (8), using isolated acremonpeptides E and F, were prepared. The planar structures of 1-10 were elucidated by HRESIMS and (1D and 2D) NMR. The absolute configurations of amino acids were determined by means of the advanced Marfey's method and X-ray single-crystal diffraction analysis. X-ray fluorescence (XRF) spectrometer was performed to disclose the elements of compound 1, indicating the existence of aluminum (Al). Al (III)-acremonpeptides E (1), Ga (III)-acremonpeptides E (5), Al (III)-acremonpeptide F (7), and Ga (III)-acremonpeptide F (8) displayed high in vitro anti-fungal activities, which are comparable to amphotericin B, against Aspergillus fumigatus and Aspergillus niger.
