Special Issue Information

Dear Colleagues,

The development of new drugs able to counteract pathogenic microbes is crucial in many fields of application due to the large increase in drug-resistant bacterial strains.

The growing problem of resistance to conventional antibiotics and the need for new antibiotics has stimulated interest in the development of new possible human therapy. Much interest has been directed towards natural molecules or antimicrobial peptides. In this respect, the study of their mechanisms of action and the identification of their protein targets could increase their specificity and power of action, leaving pathogens exposed to antibiotic treatments.

This Special Issue will be dedicated not only to the study on new antimicrobial compounds, natural or synthetic, but also to studies on already-existing compounds to identify specific protein targets and develop new molecules with improved antimicrobial profiles.

Manuscript Submission Information

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
In this article, we present polymer materials consisting of polylactide (PLA) and nisaplin (N), as well as PLA and natamax (X). These materials were obtained using the solvent method and tested by various test methods, i.e., functional properties—water vapor permeability, light transmission, gloss, [...] Read more.
In this article, we present polymer materials consisting of polylactide (PLA) and nisaplin (N), as well as PLA and natamax (X). These materials were obtained using the solvent method and tested by various test methods, i.e., functional properties—water vapor permeability, light transmission, gloss, and bactericidal activity against strains E. coli (ATCC 8739P), S. aureus (ATCC 65388), and P. aeruginosa (ATCC 8739). Furthermore, analyses were conducted to evaluate their efficacy against pathogenic fungi, including A. niger, A. flavus, A. glaucus, and A. versicolor. Mutagenicity analyses were performed using the standard Ames Test with Salmonella typhimurium. The main test methods used were ISO 22196, ISO 846. The results obtained confirm the potential suitability of the films of PLA with nisaplin and natamax for applications in the food packaging industry. Full article

Seventeen adamantane derivatives were synthesized according to facile condensation reaction protocols. Spectral analysis (1H NMR and 13C NMR) was applied to confirm the chemical structure of the obtained substances. The synthesized compounds were tested for in vitro antimicrobial activity against a panel of Gram-positive and Gram-negative bacterial strains and towards fungi from Candida spp. Among them, four derivatives numbered 9, 14, 15 and 19 showed the highest antibacterial potential with MIC = 62.5–1000 µg/mL with respect to all Gram-positive bacteria. S. epidermidis ATCC 12228 was the most susceptible among the tested bacterial strains and C. albicans ATCC 10231 among fungi. Additionally, the cytotoxicity for three derivatives was measured with the use of the MTT test on A549, T47D, L929 and HeLa cell lines. Our cytotoxicity studies confirmed that the tested substances did not cause statistically significant changes in cell proliferation within the range of the tested doses. Full article
