In the course of our screening for new anticancer compounds produced by marine bacteria, we found that a new genus marine bacterium Pelagiobacter variabilis produced new phenazine antibiotics, pelagiomicins A, B and C. Those compounds were labile in water and alcohols. The absolute structure of the main component; pelagiomicin A, and the structures of the minor ones were determined from the spectroscopic data and by synthesis. Pelagiomicin A exhibits activity against Gram-positive and -negative bacteria and antitumor activity in vitro and in vivo.
在筛选海洋细菌产生的新型抗癌化合物的过程中,我们发现一种新属的海洋细菌 Pelagiobacter variabilis 产生了新的吩嗪抗生素 Pelagiomicins A、B 和 C。这些化合物在水和酒精中不稳定。主要成分的绝对结构;根据光谱数据和合成确定了pelagiomicin A 和次要化合物的结构。 Pelagiomicin A 在体外和体内均表现出抗革兰氏阳性和阴性细菌的活性以及抗肿瘤活性。
