Mechanism and Anticancer Activity of the Metabolites of an Endophytic Fungi from Eucommia ulmoides Oliv
Backgroud: Pinoresinol (Pin) and pinoresinol monoglucoside (PMG) are plant-derived lignan molecules with multiple functions. We showed previously that an endophytic fungus from Eucommia ulmoides Oliv., Phomopsis sp. XP-8 is able to produce Pin and PMG. Objective: This study was
carried out to test the anti-tumor capability of the culture of XP-8 and identify the major effective compounds. Method: The fungal culture was added in the culture of HepG2 and K562 cells, and the viabilities of these cells were detected and the possible mechanism was analyzed.
Result: The fungal culture showed significant capaiblity in decreasing the viability of tumor cells and induce apoptosis via up-regulation of the expression of apoptosis-related genes. It also significantly inhibited the adhesion and migration of HepG2 cells by blocking MMP-9 expression. Pin
and PMG were isolated from the growth culture and shown to be the major effective components for inhibition. Conclusion: The study indicated the potential application of XP-8 in the production of anti-tumour products by the bioconversion of glucose.
Aims: Pyrrole derivatives represent a very interesting class as biologically active compounds. The objective of our study was to investigate the cytotoxic and apoptotic effects and antioxidant activity of the newly synthesized pyrrole derivatives. Method: A series of novel pyrro ... mehr
Background: Protease activated receptor-1 (PAR1) is a G-coupled receptor activated by α-thrombin and other proteases. Several reports have demonstrated the PAR1 involvement in tumorigenesis and tumor progression. In order to investigate on potential use of PAR1 antagonists as
