  • Title: Pestaloporonins: Caryophyllene-Derived Sesquiterpenoids from a Fungicolous Isolate of Pestalotiopsis sp.
    Author: Hwang IH, Swenson DC, Gloer JB, Wicklow DT.
    Journal: Org Lett; 2015 Sep 04; 17(17):4284-7. PubMed ID: 26287562.
    Abstract:
    Three new sesquiterpenoids (pestaloporonins A-C; 1-3) related to the caryophyllene-derived punctaporonins were isolated from cultures of a fungicolous isolate of Pestalotiopsis sp. The structures of 1-3 were determined by analysis of NMR and HRMS data, and the structure of 1, including its absolute configuration, was confirmed by X-ray crystallographic analysis. Compounds 1 and 2 contain new bicyclic and tricyclic ring systems, respectively.
