Since Notch signaling plays important roles in cell proliferation and differentiation, aberrant activation of this signaling contributes to cancer progression. In neural stem cells, Notch signaling inhibits differentiation by activating HES1 expression. Therefore, Notch signaling inhibitors may be
A homodimeric trypsin inhibitor with a molecular mass of 54 kDa was isolated from the seeds of Clausena lansium (Lour) Skeels with a very simple procedure comprising extraction with an aqueous buffer and ion exchange chromatography on CM-cellulose. It inhibited trypsin with an IC50 of 2.2 nM but was
OBJECTIVE
Mast cells play a central role in allergic and chronic inflammation. Extracts from Clausena lansium (Lour.) Skeels (Rutaceae) possess many pharmacological effects including anti-inflammatory, anti-oxidant, anti-cancer, and anti-trichomonal activities. In addition, the leaves and fruit are
Six compounds were isolated from the stems of Clausena lansium (Lour.) Skeels by repeated sillica gel column chromatography. Their chemical structures were elucidated on the basic of physicochemical and spectroscopic data. Among them, 8-geranyloxypsolaren (3) and
