Abstract:
The present invention provides Wondonin A of general formula (I), which is extracted from a two-sponge association of phylum Porifera (sponge) and has antiangiogenic activity, and a process for preparing the same. Wondonin A has no cytotoxicity, but has an inhibitory activity against angiogenesis which is one of the crucial mechanisms of cancer cell metastasis, thus, it can be applied not only as an anticancer drug but also as a therapeutic agent of angiogenesis-associated diseases such as cardiac ischemia, rheumatoid arthritis, and diabetes mellitus.
