The synthesis and antimicrobial activity heterocyclic analogs of the diterpenoid totarol are described. An advanced synthetic intermediate with a ketone on the A-ring is used to attach fused heterocycles and a carbon-to-nitrogen atom replacement is made on the B-ring by de novo synthesis. A-ring analogs with an indole attached exhibit, for the first time, enhanced antimicrobial activity relative to
描述了二萜类总酚的合成和抗菌活性杂环类似物。使用在A环上带有酮的高级合成中间体连接稠合的杂环,并通过从头合成在B环上进行碳氮原子取代。相对于母体天然产物,带有吲哚的A-环类似物首次展现出增强的抗菌活性。初步实验表明,吲哚类似物没有针对鱼油中假设的细菌细胞分裂蛋白FtsZ。
