  • Publication number: 20090221568
    Abstract: FtsZ, the bacterial analog of tubulin, is a promising new target for developing new antibiotics. It has been shown that polyphenols inhibit the GTPase activity of FtsZ, thereby inhibiting Z-ring formation during mitosis. The present invention provides novel polyphenols compounds, which can be accessed by the synthesis of dichamametin and 2??-hydroxy-5?-benzylisouvarinol-B as described herein. These novel compounds are useful in treating infections, particularly infections caused by gram-positive organisms. Methods of preparing the inventive compounds are also provided. The compounds are prepared by the benzylation of pinocembrin or chrysin core structure. Pharmaceutical compositions and method of using the compounds to treat disease are also provided. These compounds may be screened for antimicrobial activity as well as other biological activities such as anti-neoplastic, anti-inflammatory, immunosuppressive, and cytotoxic activity.
