| Abstract: | Two novel cucurbitacins designated as neocucurbitacins A (1), possessing inhibitory activity of polyoma enhancer binding protein 2alphaA (PEBP2alphaA) and osteoclastogenesis-inhibitory factor (OCIF) gene expression in human osteoblast-like cells, and B (2) were isolated from the fruit of Luffa operculata. Their structures have been determined by extensive spectroscopic investigation. |
