Special Issue Information
Dear Colleagues,
Hydrogen sulfide (H2S) is now widely acknowledged as the third endogenous gasotransmitter, joining nitric oxide (NO) and carbon monoxide (CO) as a key regulator of diverse biological processes. It influences numerous physiological systems, including vascular regulation, immune responses, redox balance, and mitochondrial function. Despite its important roles, the full characterization of H2S signaling is limited because of its low endogenous concentrations and rapid reactivity within biological systems. To overcome these challenges and to better define the physio-pathological functions of this gas, natural sources of H2S have been used, and significant efforts have been directed toward the development of synthetic H2S sources. In particular, the design of H2S-donor compounds—capable of releasing the gas in a controlled and physiologically relevant manner—has become an essential strategy for elucidating its functions and therapeutic potential.
We invite you to submit your latest research findings or review articles to this Special Issue, as we aim to gather cutting-edge research focused on the chemistry, biology, and pharmacology of H2S and its donors. This Special Issue offers a multidisciplinary platform for advancing our understanding of sulfur-based signaling in both physiological and pathological contexts, highlighting novel pharmacological tools and mechanistic insights.
We look forward to your valuable contributions.

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. Antioxidants 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). 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.
