聚醚类抗生素是一类重要的微生物次级代谢产物,其结构特征为分子中含有多个环醚单元,且分子一端有羧基,该类抗生素主要由链霉菌产生,具有离子载体性质,容易络合金属离子,常见的聚醚类抗生素有莫能菌素、南昌霉素、尼日利亚菌素等。聚醚类抗生素家族中含有一类特殊的天然产物,即茚满霉素类,该类化合物含有反式四氢茚满环和吡咯酮结构单元,其代表分子是茚满霉素(indanomycin,X-14547A),最早分离自链霉菌Streptomyces sp. NRRL 8167[1]。与其结构相似的化合物还有cafamycin[2]、16-deethylindanomycin[3]及其类似物[4]、homoindanomycin、stawamycin[5-6]和JBIR-11[7]等。茚满霉素类化合物均具有良好的抗菌、杀虫和抗原虫等活性,其特殊的化学结构和显著的生物活性引起了药物学家们的广泛兴趣,不少化学家对其进行全合成,生物学家也对含有该类特殊结构的天然产物的生物合成机制进行研究。
本文就茚满霉素类化合物的天然发现、生物活性、化学合成和生物合成进行总结,为开发该类天然产物的药用价值提供科学基础,为采用组合生物合成的方法对该类化合物进行结构改造提供新思路。

摘要: 茚满霉素类天然产物是一类具有反式四氢茚满环(indan)结构的微生物次级代谢产物,该类化合物普遍具有良好的抗菌、杀虫以及抗肿瘤等生物活性,因而引起了药物化学家和生物学家的广泛兴趣。对1979年至今有关茚满霉素类化合物的天然发现、生物活性、化学合成以及生物合成等方面的研究进展进行综述,为该类抗生素的基础和应用研究提供科学参考。Abstract: Indanomycins are a class of secondary metabolites of microorganisms with a trans-tetrahydroindan (indane) ring. These compounds generally have good antibacterial, insecticidal and antitumor biological activities, which have caused wide interest for medicinal chemists and biologists. This review summarizes the research progress of the discovery, biological activity, chemical synthesis and biosynthesis of indanomycin compounds since 1979 and provides scientific reference for the research and development of indanomycin antibiotics.
