Parkinson's disease (PD) is a neurodegenerative disease affecting up to 80% of dopaminergic neurons in the nigrostriatal pathway. FLZ, a novel synthetic squamosamide derivative from a Chinese herb, has been shown to have neuroprotective effects in experimental PD models. In this study, we carried out a set of in vitro and in vivo experiments to address the(More)
Many deleterious effects on the skin have been associated with the ultraviolet B (UVB) portion of the solar spectrum. The role of green tea polyphenols (GTP) in protecting HaCaT cells against the UVB-induced damages was examined. The promotion effect of low level GTP on cell viability was revealed in a dose-dependent manner. High level GTP had a cytotoxic(More)
Chrysanthemum indicum flower is a traditional Chinese medicine with strong aroma and many previous studies focused on its essential oil. GC/MS and HPLC were used to determine its volatiles, flavonoids and flavonoid glycosides. Sixty three volatiles were detected and the abundant volatiles included 2,6,6trimethyl-bicyclo[3.1.1]hept-2-en-4-ol,(More)
Parkinson’s disease (PD) is a chronic, progressive neurodegenerative disorder characterized by motor impairments and loss of dopaminergic neurons in the substantia nigra. FLZ (formulated as: N-2-(4-hydroxy-phenyl)-ethyl]-2-(2, 5-dimethoxy-phenyl)-3-(3-methoxy-4-hydroxy-phenyl)-acrylamide) is a novel synthetic derivative of squamosamide from a Chinese herb(More)
PURPOSE To examine the protective effect of green tea polyphenols against ultraviolet B (UVB)-induced damage to retinal pigment epithelial (RPE) cells. METHODS Green tea polyphenols (GTP) was used to treat RPE cells before or after exposure to UVB. Viability of RPE cells was tested by 3,(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT)(More)
Neuroinflammation in central nervous system, featured by glial cells activation, can always be found during the development of neurodegenerative diseases. Astrocytes, the most abundant glial cells in the brain, can release both pro-inflammatory and anti-inflammatory factors, thus playing a crucial role in the neuroinflammation. A variety of(More)
Alzheimer's disease (AD) is the most common neurodegenerative disorder in which neuroinflammation plays an important role. FLZ is a novel synthetic derivative of natural squamosamide. Previous studies demonstrated that FLZ had neuroprotective effects on AD models and showed strong anti-inflammatory property in Parkinson's disease models. However, whether(More)
