Discovery of Novel Antimicrobial Lead Compounds and Innovative Strategies Based on Natural Products

About this Research Topic

Background

Natural products (NPs) have been an important source of drug discovery and development due to their novel structures and wide range of pharmacological activities. Especially in the discovery of antibiotics, most antibiotics are derived from NPs and their derivatives, such as penicillin G, amoxicillin, oxytetracycline, and minocycline. NPs have particular advantages over purely synthetic molecules. They are evolutionarily optimized structurally for specific biological functions, including anti-infective activity, interaction with other organisms, and receptor/protein binding. In addition, NPs have a broader chemical space than typical synthetic small molecule compound libraries, bringing the advantages of scaffold diversity and structural novelty. Due to the large number of sp3 carbon atoms and chiral centers, NPs have the unique ability to interact with receptors and demonstrate targeting selectivity. Therefore, NP-based antimicrobial drug discovery is one of the hot topics in current research.

This Research Topic aims to collate cutting-edge research advances regarding NPs and their analogues as antimicrobial agents, to infuse renewed vigor into this vital field. This solicitation mainly focuses on four aspects: (1) the discovery and characterization of antimicrobial NPs featuring novel chemotypes and unique mechanisms of action; (2) investigation into the strategies NPs employ to counteract bacterial resistance, including their role as resistance-modifying or anti-virulence agents, and their synergistic effects with existing antibiotics; (3) the rational optimization and structural modification of promising NP scaffolds for the development of high-efficacy lead compounds with improved drug-like properties; and (4) the innovative development of NP-based antimicrobial materials (e.g., coatings, implants) and intelligent, targeted delivery systems to enhance therapeutic efficacy.

This Research Topic aims to showcase the latest advancements in harnessing NPs and their analogues to combat antibacterial resistance. We seek to bridge fundamental discovery with translational applications, highlighting the unique role of NPs in inspiring next-generation anti-infective strategies. Specific themes of interest include:
- Discovery of novel NPs with unique chemotypes and mechanisms of action.
- Investigation of NPs as resistance-modifying, anti-virulence, or synergistic agents.
- Optimization of NP scaffolds for high-efficacy lead compound development.
- Development of innovative NP-based antimicrobial materials and smart delivery systems.
We welcome the submission of Original Research, Review, and Mini-Review articles that address these challenges and contribute to revitalizing the antibiotic pipeline.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
