Abstract:
Sixteen azaphilone derivatives, including four new compounds, penicilazaphilones H and I (1 and 2), 11-epi-geumsanol F (3), and 11-epi-geumsanol B (4), together with twelve known analogues (5–16), were isolated from the algae-derived fungus Penicillium sclerotiorum purified from fresh marine macroalgae Grateloupia sp. The planar structures of 1–4 were identified by HRESIMS, IR, NMR, and UV spectroscopic analyses. Their absolute configurations were unambiguously determined by comparing the NMR and ECD spectra. These secondary metabolites were evaluated on the anti-angiogenic effect in human endothelial progenitor cells (EPCs). As a result, compounds 12, 14, and 16 exhibited anti-angiogenic activities by blocking cell growth, migration, and tube formation of EPCs. Additionally, the structure–activity relationships (SAR) for anti-angiogenic effects of isolated azaphilones were deduced.
