The adhesion of cancer cells to the extracellular matrix (ECM) is crucial for cell proliferation, survival, and metastasis. Thus, it is necessary to inhibit cell-ECM adhesion by blocking the activation of the associated signaling to control cancer. Here, we identify erybraedin A (EBA) as a potential

Pterocarpans, the second group of natural isoflavonoids, have received considerable interest on account of their medicinal properties. These drugs are employed as antitoxins, but display antifungal, antiviral and antibacterial properties as well. Erybraedin C and bitucarpin A are two new

A new prenylated pterocarpan, named morisianine, was isolated together with the known secondary metabolites erybraedin C, psoralen and angelicin from the seeds of Bituminaria morisiana. The structures of the compounds were elucidated mainly by 1D and 2D NMR experiments as well as mass spectrometry.

Plant-derived isoflavones are currently receiving much attention because of their phyto-estrogenic, antioxidant, anti-mutagenic, and anti-tumor activities. In this study we have evaluated the clastogenic and anti-clastogenic activities in human lymphocytes of two structurally related pterocarpans,

Using cytotoxicity against KB cancer cells as a lead, bioguided-fractionation of the petroleum ether and ethyl acetate extracts of Bituminaria morisiana leaves led to the isolation of two new pterocarpans, namely 3,9-dihydroxy-4-(3,3-dimethylallyl) [6a R, 11a R]-pterocarpan,
