Scientists are constantly searching for phytochemical compounds with anti-cancer activity. In this study, activity of plant extract NPB001-05 from Piper betle was tested on human chronic myelogenous leukemia (CML) xenograft models. NPB001-05 was active when dosed orally (500 mg/kg) once or twice a
Total chlorophyll content and chlorophyllase (chlorophyll-chlorophyllido hydrolase EC 3.1.1.14) activity in fresh leaves of Piper betle L. landrace KS was, respectively, twofold higher and eight fold lower than KV, showing negative correlation between chlorophyll and chlorophyllase activity.
The deregulated activity of the Bcr-Abl tyrosine kinase provides a rational basis for the development therapeutics in all phases of Chronic Myelogenous Leukemia (CML). Although a well studied imatinib therapy has clinical success against CML, resistance to imatinib due to mutations in the kinase
Areca quid (AQ) chewing has been implicated an independent risk factor for the development of oral cancer. Taiwanese areca quid (AQ) refers to a combination of areca nut (AN), lime, and inflorescence of Piper betle Linn. (IPB) or Piper betle leaf (PBL). Studies of AQ in other countries reported that
Chewing areca quid (AQ) has been implicated as a major risk factor for the development of oral squamous-cell carcinoma (OSCC). Recent studies have suggested that AQ-generated reactive oxygen species (ROS) is one of the contributing factors for oral carcinogenesis. However, the AQ used in Taiwan is
