PAK1 (p21-activated kinase 1) is an emerging target for the treatment of hair loss (alopecia) and cancer; therefore, the search for PAK1 blockers to treat these PAK1-dependent disorders has received much attention. In this study, we evaluated the anti-alopecia and anticancer effects of PAK1

Plants play an important role in anti-cancer drug discovery, therefore, the current study aimed to evaluate the biological activity of Alpinia zerumbet (A. zerumbet) flowers.

The phytochemical and biological criteria of

From a viewpoint of cancer chemoprevention, possible anti-tumour promoting properties of daily food items and some of their active constituents have been investigated by a convenient in-vitro assay, the Epstein-Barr virus (EBV) activation test. In a screening test for the inhibitory activity toward

In recent years, there have been considerable efforts to search for naturally occurring substances for intervention of carcinogenesis. Many components from medicinal or dietary plants have been identified to possess potential chemopreventive properties. For instance, curcumin, a yellow colouring

BACKGROUND Alpinia oxyphylla is a common remedy in traditional Chinese medicine. Yakuchinone A is a major constituent of A. oxyphylla and exhibits anti-inflammatory, antitumor, antibacterial, and gastric protective activities. METHODS Antioxidant and antitumor characteristics of yakuchinone A in

BACKGROUND Flavonoids are a diverse family of natural phenolic compounds commonly found in fruits and vegetables. Epidemiologic studies showed that flavonoids also reduce the risk of colon cancer. Tectochrysin is one of the major flavonoids of Alpinia oxyphylla Miquel. However, the anti-cancer

OBJECTIVE Previous in vitro and in vivo studies have reported that 1'-S-1'-acetoxychavicol acetate (ACA) isolated from rhizomes of the Malaysian ethno-medicinal plant Alpinia conchigera Griff (Zingiberaceae) induces apoptosis-mediated cell death in tumour cells via dysregulation of the NF-κB

The leaves and roots of Alpinia pricei Hayata are used as a traditional wrapping for food and as a cooking substitute for fresh ginger. Our previous study showed that ethanol extracts from the roots of A. pricei Hayata (EEAP) and its phenolic compounds have anti-inflammatory effects. The aims of

Recent advances in mammography screening, chemotherapy, and adjuvant treatment modalities have improved the survival rate of women with breast cancer. Nevertheless, the breast tumor with metastatic progression is still life-threatening. Indeed, combination therapy with Ras-ERK and PI3K inhibitors is

Since the major approach in searching for potential anticancer agents over the last 50 years has been based on selective cytotoxic effects on mammalian cancer cell lines, cell-based methods for cytotoxicity are described and compared. The sulphorhodamine B (SRB) assay is described in detail as the

Chalcones found in fruits and vegetables have promising cancer chemopreventive properties. This study attempts to identify the anticancer efficacies of chalcone flavokawain B (FKB) in the rhizomes of Alpinia pricei Hayata by examining key molecular events in non-small-cell lung cancer (A549) cells.

Galangin is an active pharmacological ingredient from propolis and Alpinia officinarum Hance, and has been reported to have anti-cancer and antioxidative properties. Berberine, a major component of Berberis vulgaris extract, exhibits potent anti-cancer activities through distinct molecular

OBJECTIVE To study the chemical constituents from the seeds of A. katsumadai, and their inhibition on NF-kappaB activation and antitumor effect. METHODS Tweleve compounds were isolated from the seeds of Aplinia katsumadai on repeated column chromatography on silica gel, and Sephadex LH-20, and their

OBJECTIVE The study was formulated with the objective to assess phytochemical constituents, antibacterial activity and anticancer activity of Alpinia purpurata. METHODS The leaves of A. purpurata were washed thoroughly by tap water, shade dried and powdered. The plant powder was extracted with

Two new diarylheptanoids (1, 2), together with two known analogs (3, 4), were isolated from the rhizomes of Alpinia officinarum. The new compounds were elucidated to be (5S)-5-hydroxy-7-(3, 4-dihydroxyphenyl)-1-phenyl-3-heptanone (1) and (5R)-5-hydroxy-7-(3-methoxy-4,
