衣原体是广泛分布于人类群体中的病原体,可导致严重的生殖和其他健康问题。在我们从海洋来源的微生物中寻找新的抗衣原体代谢物的过程中,从海绵来源的放线菌中分离到了一个新的(1)和两个已知的(2,3)二聚吲哚衍生物。这些代谢物的化学结构通过核磁共振波谱数据和CD计算得到确证。三种代谢物均以浓度依赖的方式抑制衣原体生长。其中化合物1的抗衣原体活性最强,其IC50值为46.6~96.4μM。化合物似乎通过干扰网状小体复制而不是直接灭活具有感染性的基本体来针对衣原体发育周期的中期。
Chlamydiae are widely distributed pathogens of human populations, which can lead to serious reproductive and other health problems. In our search for novel antichlamydial metabolites from marine derived microorganisms, one new (1), along with two known (2, 3) dimeric indole derivatives were isolated from sponge derived actinomycete Rubrobacter radiotolerans. The chemical structures of these metabolites were elucidated by NMR spectroscopic data as well as CD calculations. All three metabolites suppressed chlamydial growth in a concentration-dependent manner. Among them, compound 1 exhibited the most effective antichlamydial activity with IC50 values of 46.6 ~ 96.4 μM in production of infectious progeny. Compounds appeared to target the mid-stage of the chlamydial developmental cycle by interfering with reticular body replication but not directly inactivating infectious elementary body.
