Sulfur donor

“Sulfur donor” is not the name of a specific molecule, receptor, or canonical drug target. Instead, it is a generic chemical or biochemical term referring to any compound that donates sulfur atoms for incorporation into other molecules or for use in chemical reactions. In chemistry and materials science, “sulfur donors” such as tetramethylthiuram disulfide are used to introduce monosulfide interlinks between polymer molecules during processes like rubber vulcanization[7]. In coordination chemistry, “sulfur-donor ligands” are compounds with sulfur atoms that coordinate to metals[9]. In biochemistry and cell biology, the term may refer to endogenous metabolites or enzymes that provide activated forms of sulfur for biosynthetic pathways—such as cysteine serving as a thiol-reduced sulfur donor for organic molecule synthesis in plants and animals[5], or proteins like IscS/rhodanese acting as enzymatic sources of persulfidic (“activated”) sulfur for cofactor biosynthesis in prokaryotes[2]. More recently, “supersulfide donors” have been studied for their ability to deliver reactive sulfane/supersulfide species into cells with potential antioxidant and anti-inflammatory effects; however these are classes of compounds rather than single targets[4][6]. Because "Sulfur donor" does not refer to one defined molecular entity but rather describes a functional property shared by many different molecules across diverse contexts—chemical reagents, metabolic intermediates/enzymes—it is not considered a therapeutic target such as an enzyme, receptor, transporter etc., nor does it have standardized aliases or abbreviations suitable for structured biomedical databases. If you require information on specific enzymes involved in biological sulfur donation (e.g., cystathionine β-synthase [CBS], IscS), please specify the exact protein/molecule. If you mean synthetic small-molecule donors used experimentally or therapeutically (“supersulfide donors”), those too should be named specifically. In summary: **"Sulfur donor" is not itself a canonical molecular target but rather describes any compound capable of donating sulfur atoms; thus this entry is non-specific and incorrect if treated as an individual druggable target.**
