Special Issue Information

Dear Colleagues,

Cell metabolism is tightly linked with proliferation, differentiation and functioning. The development of various pathologies, including cancer, autoimmune diseases, and endocrine diseases, is associated with the alteration of metabolic pathways. Inhibitors of metabolic enzymes and metabolite transporters can be used for their treatment, as exemplified by a wide array of drugs such as statins, metformin, sulfasalazine, methotrexate, and eflornithine.

Reactive oxygen species (ROS) comprise a group of oxygen intermediates generated in different cell compartments. Their overproduction is associated with the development of various pathologies. ROS modulate signaling pathways, as they can specifically target the cysteine residues of certain proteins, affecting their activity. Changes in cellular redox status are tightly linked to the dysregulation of metabolic pathways.

Viral infections interfere with various metabolic and redox pathways of host cells. In the current Special issue, we would like to bring together research papers and reviews on an interplay between viral infections and metabolic and redox pathways. The topics include but are not limited to:

  • Alteration of redox and metabolic pathways in infected cells;
  • Role of ROS and metabolic pathways in virus replication;
  • Role of changes in redox and metabolic pathways in virus pathogenesis;
  • Potential activity of antioxidants and inhibitors of metabolic enzymes as antiviral agents or drugs to treat virus-associated diseases;
  • Redox biology and metabolism studies of non-communicable diseases, elements of which can be used in virology.

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. Biomolecules 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 2700 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Rose Bengal (RB) is an anionic xanthene dye with multiple useful biological features, including photosensitization properties. RB was studied extensively as a photosensitizer, mostly for antibacterial and antitumor photodynamic therapy (PDT). The application of RB to virus inactivation is rather understudied, and no RB derivatives have been developed as antivirals. In this work, we used a synthetic approach based on a successful design of photosensitizing antivirals to produce RB derivatives for virus photoinactivation. A series of n-alkyl-substituted RB derivatives was synthesized and evaluated as antiviral photosensitizers. The compounds exhibited similar 1O2 generation rate and efficiency, but drastically different activities against SARS-CoV-2, CHIKV, and HIV; with comparable cytotoxicity for different cell lines. Submicromolar-to-subnanomolar activities and high selectivity indices were detected for compounds with C4-6 alkyl (SARS-CoV-2) and C6-8 alkyl (CHIKV) chains. Spectrophotometric assessment demonstrates low aqueous solubility for C8-10 congeners and a significant aggregation tendency for the C12 derivative, possibly influencing its antiviral efficacy. Initial evaluation of the synthesized compounds makes them promising for further study as viral inactivators for vaccine preparations. Full article
