A methoxyflavanone derivative from the Asian medicinal herb (Perilla frutescens) induces p53-mediated G(2)/M cell cycle arrest and apoptosis in A549 human lung adenocarcinoma.[Pubmed:28710570]
Cytotechnology. 2018 Jun;70(3):899-912.
Perilla frutescens is an Asian dietary herb consumed as an essential seasoning in Japanese cuisine as well as used for a Chinese medicine. Here, we report that a newly found methoxyflavanone derivative from P. frutescens (Perilla-derived methoxyflavanone, PDMF; 8-Hydroxy-5,7-dimethoxyflavanone) shows carcinostatic activity on human lung adenocarcinoma, A549. We found that treatment with PDMF significantly inhibited cell proliferation and decreased viability through induction of G(2)/M cell cycle arrest and apoptosis. The PDMF stimulation induces phosphorylation of tumor suppressor p53 on Ser15, and increases its protein amount in conjunction with up-regulation of downstream cyclin-dependent kinase inhibitor p21(Cip1/Waf1) and proapoptotic caspases, caspase-9 and caspase-3. We also found that small interfering RNA knockdown of p53 completely abolished the PDMF-induced G(2)/M cell cycle arrest, and substantially abrogated its proapoptotic potency. These results suggest that PDMF represents a useful tumor-preventive phytochemical that triggers p53-driven G(2)/M cell cycle arrest and apoptosis.
A flavanone derivative from the Asian medicinal herb (Perilla frutescens) potently suppresses IgE-mediated immediate hypersensitivity reactions.[Pubmed:27986566]
Biochem Biophys Res Commun. 2017 Jan 29;483(1):674-679.
Perilla frutescens is a dietary leafy herb consumed as a traditional Japanese condiment as well as used for Chinese medicine with anti-inflammatory activity. Here we report a hitherto-unrecognized P. frutescens phytochemical that potently suppresses IgE-mediated type I hypersensitivity reactions. Structural analysis reveals that the purified anti-allergic compound (Perilla-derived methoxyflavanone, PDMF) is identified as 8-Hydroxy-5,7-dimethoxyflavanone. PDMF significantly inhibits IgE-mediated histamine release from RBL-2H3 rat basophilic leukemia cells as compared with those seen in known P. frutescens-derived anti-inflammatory polyphenols. We also show that oral administration of PDMF not only suppresses passive cutaneous anaphylaxis, but also prevents allergic rhinitis-like nasal symptoms in a murine model of Japanese cedar pollinosis. Mechanistically, PDMF negatively regulates Akt phosphorylation and intracellular Ca(2+) influx, both of which are essential for mast cell secretory granule translocation and its exocytosis upon high-affinity IgE receptor (FcepsilonRI) cross-linking. These results represent PDMF as a new potent anti-allergic phytochemical useful for prevention of IgE-driven hypersensitivity reactions.
