沙眼衣原体是一种代谢能力有限的专性细胞内细菌,具有富塔洛苷途径来合成甲基萘醌。Futalosine途径酶有望成为窄谱抗生素靶点,但衣原体甲基萘醌生物合成的活性和必要性尚未确定。本研究通过液相色谱-串联质谱法鉴定了甲基萘醌-7 (MK-7)为沙眼沙眼衣原体产生的醌。一项基于免疫荧光的检测显示,用futalosine途径抑制剂二十二碳六烯酸(DHA)治疗沙眼衣原体感染的HeLa细胞可减少包涵体数量、包涵体大小和传染性后代。补充MK-7纳米颗粒恢复了DHA对包合数的影响,表明futalosine途径是DHA在该系统中的靶点。这些结果为甲萘醌生物合成抑制剂在抗衣原体开发中的应用打开了大门。
Chlamydia trachomatis, an obligate intracellular bacterium with limited metabolic capabilities, possesses the futalosine pathway for menaquinone biosynthesis. Futalosine pathway enzymes have promise as narrow-spectrum antibiotic targets, but the activity and essentiality of chlamydial menaquinone biosynthesis have yet to be established. In this work, menaquinone-7 (MK-7) was identified as a C. trachomatis-produced quinone through liquid chromatography-tandem mass spectrometry. An immunofluorescence-based assay revealed that treatment of C. trachomatis-infected HeLa cells with the futalosine pathway inhibitor docosahexaenoic acid (DHA) reduced inclusion number, inclusion size, and infectious progeny. Supplementation with MK-7 nanoparticles rescued the effect of DHA on inclusion number, indicating that the futalosine pathway is a target of DHA in this system. These results open the door for menaquinone biosynthesis inhibitors to be pursued in antichlamydial development.
