Angiogenesis is the process of new blood vessel formation. Excessive angiogenesis is a critical factor in the progression of cancer, macular degeneration, and other chronic inflammatory diseases. When investigating the effects of crude extracts of cultured marine microorganisms, an extract of the cultured Streptomyces sp. YP127 strain was found to inhibit human umbilical vein endothelial cell (HUVEC) tube formation. Bioassay-guided fractionation and spectroscopic data analyses led to the identification of napyradiomycin A1 (1) as an antiangiogenic component of the extract. Compound 1 inhibited HUVEC tube formation in a concentration-dependent manner. It inhibited endothelial cell proliferation but did not affect human dermal fibroblast proliferation. Compound 1 also suppressed migration and invasion of vascular endothelial cells. In addition, compound 1 suppressed vascular endothelial cadherin expression and increased the permeability of the endothelial cell membrane. These results suggested that compound 1 modulates cell permeability and inhibits the angiogenesis of endothelial cells.
