Special Issue Information

Dear Colleagues,

The inappropriate use of antibacterial agents has promoted the emergence of resistant strains of bacteria and poses a significant threat to public health. The pervasive problem of antimicrobial resistance (AMR) is exacerbating healthcare crises worldwide, leading to increased mortality rates and rising healthcare costs. According to the World Health Organization (WHO), antibiotic resistance could cause up to 10 million deaths a year worldwide by 2050. Research into new antibiotics is therefore urgently needed.

This Special Issue aims to present a broad spectrum of research in the field of medicinal chemistry of antibacterial compounds and we welcome manuscripts that address both traditional and computational drug design strategies, from target identification to the application of machine learning and the screening of diverse chemical libraries in the discovery processes. In terms of publication priorities, modern methods, including virulence factor inhibitors, nanoparticles, antimicrobial peptides, phage therapy, and antisense oligonucleotides, are at the forefront. Papers dealing with the design and synthesis of new classes of antibacterial agents that introduce novel mechanisms of action, as well as studies focusing on the chemical synthesis and optimization of existing antibacterial agents, whether semi-synthetic or fully synthetic, are also welcome.

We are keen to publish ground-breaking research on the design and development of novel antibacterial agents for human and veterinary medicine. Authors are encouraged to submit original papers or reviews covering all aspects of this important topic.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Antibiotics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs).

This review explores the potential of antimicrobial metabolites derived from Caucasian medicinal plants as alternatives to conventional antibiotics. With the rise of antibiotic resistance posing a global health threat, there is a pressing need to investigate alternative sources of antimicrobial agents. Caucasian medicinal plants have traditionally been used for their therapeutic properties, and recent research has highlighted their potential as sources of antimicrobial compounds. Representatives of 15 families of Caucasian medicinal plant extracts (24 species) have been explored for their efficacy against these pathogens. The effect of these plants on Gram-positive and Gram-negative bacteria and fungi is discussed in this paper. By harnessing the bioactive metabolites present in these plants, this study aims to contribute to the development of new antimicrobial treatments that can effectively combat bacterial infections while minimizing the risk of resistance emergence. Herein we discuss the following classes of bioactive compounds exhibiting antimicrobial activity: phenolic compounds, flavonoids, tannins, terpenes, saponins, alkaloids, and sulfur-containing compounds of Allium species. The review discusses the pharmacological properties of selected Caucasian medicinal plants, the extraction and characterization of these antimicrobial metabolites, the mechanisms of action of antibacterial and antifungal plant compounds, and their potential applications in clinical settings. Additionally, challenges and future directions in the research of antimicrobial metabolites from Caucasian medicinal plants are addressed. Full article
