A chemical investigation of the methanol extract from the roots of Cudrania tricuspidata resulted in the isolation of 16 compounds, including prenylated xanthones 1-9 and flavonoids 10-16. Their structures were identified by NMR spectroscopy and mass spectrometry and comparisons with published data.
OBJECTIVE
The present study was performed to determine the effects of the ethyl acetate extract of Cudrania tricuspidata (EACT) on interleukin (IL)-1beta-stimulated receptor activator of NF-kappaB ligand (RANKL)-mediated osteoclast differentiation.
METHODS
Bone marrow cells were harvested from
Diabetes and obesity represent the major health problems and the most age-related metabolic diseases. Protein-tyrosine phosphatase 1B (PTP1B) has emerged as an important regulator of insulin signal transduction and is regarded as a pharmaceutical target for metabolic disorders. To find novel natural
