Polyketides with IDH1 R132h and PTP1B Inhibitory Activities from the Desert-plant-derived Fungus Sp. HM 134
Overview
Affiliations
Five new polyketides named alternafurones A () and B (), alternapyrones M-O (-), together with fourteen known ones (-), were isolated from the desert-plant-derived fungus sp. HM 134. The structures of the new compounds were elucidated from spectroscopic data and ECD spectroscopic analyses. Alternafurones A and B represent polyketides with an unprecedented 6/5/6 skeleton core. Compounds , and showed definite inhibitory activities against isocitrate dehydrogenase 1 gene (IDH1 R132h) with IC values of 29.38, 19.41 and 14.14 μg/ml, respectively. Seven compounds (, , -, ) showed potent protein tyrosine phosphatase 1B (PTP1B) inhibitory activity with IC values ranging from 0.97 μg/ml to 89.80 μg/ml.
