  • two new 5 6 6 polyketide amino acid hybrids from a genetic mutant of Periconia sp f 31
    Journal of Asian Natural Products Research, 2021
    Co-Authors: Min Zhang, Jimei Liu, Ridao Chen, Kebo Xie, Dawei Chen, Jungui Dai
    Abstract:

    Peridecalins C and D (1 and 2), one decalin and one oxygen-decalin containing polyketide-amino acid hybrids with 5/6/6 ring system, was isolated from a genetic mutant of Periconia sp. F-31. Their structures were elucidated through extensive spectroscopic data analysis, including 1 D/2D NMR and HR-MS spectra. Biosynthetically, two proposed Diels-Alder reactions are supposed to be involved in the skeleton construction of 1 and 2.

    Abstract:

    Guided by our biosynthetic hypothesis, pericoannosins C-F, four new PKS-NRPS hybrid metabolites, were discovered from the endophytic fungus Periconia sp. F-31. Their structures and absolute configurations were elucidated by extensive spectroscopic data and electronic circular dichroism analyses. Preliminary biological evaluation revealed that pericoannosins C-D exhibited anti-HIV activities with IC50 values of 15.5 and 13.5 μM. Furthermore, the bioinspired syntheses of pericoannosins C-E have also been completed with high efficiency.
