    • 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.
    • FtsZ是微管蛋白的细菌类似物,是开发新型抗生素的有希望的新靶点。 已经表明多酚抑制FtsZ的GTP酶活性,从而抑制有丝分裂期间的Z-环形成。 本发明提供了新的多酚化合物,其可以通过合成如本文所述的二烟酸和2'-羟基-5'-苄基异乙肝酚B来进行。 这些新化合物可用于治疗感染,特别是由革兰氏阳性生物引起的感染。 还提供了制备本发明化合物的方法。 这些化合物是通过苯甲基纤维素或木质素核心结构的苄基化来制备的。 还提供了使用该化合物治疗疾病的药物组合物和方法。 这些化合物可以筛选抗微生物活性以及其它生物学活性,如抗肿瘤,抗炎,免疫抑制和细胞毒活性。
