Physalis minima has been traditionally used as a folk herbal medicine in China for the treatment of many inflammatory diseases. However, little is known about its anti-inflammatory constituents and associated molecular mechanisms. In our study, withaphysalin A (WA) and 2, 3-dihydro-withaphysalin C (WC), two major withanolide-type compounds, were obtained(More)
Metabolomics can be used to identify potential markers and discover new targets for future therapeutic interventions. Here, we developed a novel application of the metabonomics method based on gas chromatography-mass spectrometry (GC/MS) analysis and principal component analysis (PCA) for rapidly exploring the anticancer mechanism of physapubenolide (PB), a(More)
Physagulide P (PP), a new natural compound, was isolated from Physalis angulate L. in our laboratory. In this study, we demonstrated that PP potently suppressed cell proliferation by inducing G2/M phase arrest in MDA-MB-231 and MDA-MB-468 cells. Moreover, PP provoked apoptosis by decreasing the mitochondrial membrane potential and elevating the Bax/Bcl-2(More)
In this study, a series of 4-anilinoquinazoline derivatives bearing amino acid moiety were designed, synthesized and evaluated for biological activities. The synthesized compounds were screened for anticancer activity against human hepatocellular carcinoma cell HepG2 using SRB assay. In vitro cell growth inhibition assays indicated that compound 6m(More)
Physagulides M-O, three new withanolides (1-3), were isolated from the aerial parts of Physalis angulata L. Their structures were elucidated through extensive spectroscopic techniques, including 1D and 2D NMR, and HRESIMS. The absolute configurations (22-R) of these new compounds were determined by CD analysis. Compounds 1 and 3 showed significant selective(More)
