Abstract
Antimicrobial resistance (AMR) causes a global health threat and enormous damage for humans. Among them, Methicillin-resistant Staphylococcus aureus (MRSA) resistant to first-line therapeutic β-lactam drugs such as meropenem (MEPM) is problematic. Therefore, we focus on combination drug therapy and have been seeking new potentiators of MEPM to combat MRSA. In this paper, we report the isolation of phomoidrides A–D and its new analog, phomoidride H along with a polyketide compound, oxasetin from the culture broth of Neovaginatispora clematidis FKI-8547 strain as potentiators of MEPM against MRSA.
期刊介绍：
The Journal of Antibiotics seeks to promote research on antibiotics and related types of biologically active substances and publishes Articles, Review Articles, Brief Communication, Correspondence and other specially commissioned reports. The Journal of Antibiotics accepts papers on biochemical, chemical, microbiological and pharmacological studies. However, studies regarding human therapy do not fall under the journal’s scope. Contributions regarding recently discovered antibiotics and biologically active microbial products are particularly encouraged. Topics of particular interest within the journal''s scope include, but are not limited to, those listed below:
Discovery of new antibiotics and related types of biologically active substances
Production, isolation, characterization, structural elucidation, chemical synthesis and derivatization, biological activities, mechanisms of action, and structure-activity relationships of antibiotics and related types of biologically active substances
Biosynthesis, bioconversion, taxonomy and genetic studies on producing microorganisms, as well as improvement of production of antibiotics and related types of biologically active substances
Novel physical, chemical, biochemical, microbiological or pharmacological methods for detection, assay, determination, structural elucidation and evaluation of antibiotics and related types of biologically active substances
Newly found properties, mechanisms of action and resistance-development of antibiotics and related types of biologically active substances.
