2. 6-Prenylnaringenin and 8-prenylnaringenin have anti-cancer potential , dose-dependent reduction of cellular proliferation of human PC-3 prostate cancer and UO.31 renal carcinoma cells upon treatment
3. 6-Prenylnaringenin can inhibit 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced inflammation (1μg/ear) in mice, it also exhibits inhibitory effects on skin-tumor promotion in anin vivo two-stagemouse-skin carcinogenesis test based on 7,12-dimethylbenz[a]- anthracene (DMBA) as initiator and with TPA as promoter.
4. 6-Prenylnaringenin exhibits both mixed and non-competitive inhibitory characteristics against tyrosinase, tyrosinase is the rate-limiting enzyme for the production of melanin and other pigments via the oxidation of l-tyrosine.
1. 6-Shogaol enhances TRAIL-mediated apoptosis in renal carcinoma Caki cells via ROS-mediated cytochrome c release and down-regulation of c-FLIP(L) expression.
2. 6-Shogaol impairs cancer development and lung metastasis by inhibiting the secretion of CC-chemokine ligand 2 (CCL2) in tumor-associated dendritic cells.
3. 6-Shogaol shows significant neuroprotective effects in vivo in transient global ischemia via the inhibition of microglia.
4. 6-Shogaol can inhibit the growth of human pancreatic tumors and sensitize them to gemcitabine by suppressing of TLR4/NF-κB-mediated inflammatory pathways linked to tumorigenesis.
5. 6-Shogaol reduces the inflammatory response and protected the femoral cartilage from damage produced in a CFA monoarthritic model of the knee joint of rats.
6. 6-Shogaol induces apoptosis in human hepatocellular carcinoma cells in relation to caspase activation and endoplasmic reticulum (ER) stress signaling, affects the ER stress signaling by regulating unfolded protein response (UPR) sensor PERK and its downstream target eIF2α.
1. 3'4'7-Trihydroxyflavone can markedly inhibit the receptor activator of nuclear factor kappa B ligand (RANKL) induced osteoclastic differentiation from mouse bone marrow derived macrophages (BMMs), it inhibits osteoclastogenesis via nuclear factor of activated T cells c1 (NFATc1).
