A study utilized an OSMAC (One Strain Many Compounds) strategy to investigate the secondary metabolites and anti-inflammatory effects of the endophytic fungus Penicillium herquei JX4 found in the plant Ceriops tagal.
The researchers isolated, purified, and identified compounds from the fungus using various chromatography techniques, leading to the discovery of two new pinophol derivatives, pinophol H(1) and pinophol I(2).
Among these derivatives, pinophol H(1) exhibited strong inhibitory activity against nitric oxide production in mouse macrophage cells, demonstrating its potential as an anti-inflammatory agent with an IC_(50) value of 8.12 μmol
