Zinc acetate dihydrate

Zinc acetate dihydrate (CAS No.: 5970-45-6) is an inorganic zinc salt widely used as a research grade trace metal source and experimental modulator of metal dependent biological processes in biomedical and drug discovery studies, where it is commonly categorized within metal ion reagents for chemical biology, infection biology, and micronutrient signaling research rather than as an organic small molecule probe. In mechanistic contexts, its activity is primarily attributed to delivery of bioavailable zinc ions that regulate zinc binding proteins and zinc responsive transcriptional programs, including induction of metallothionein expression in intestinal and other cell based systems, modulation of cellular metal homeostasis networks that intersect with copper handling pathways, and interference with selected viral enzymatic functions such as retroviral reverse transcriptase associated processes in formulation oriented antiviral screening paradigms. Published research usage generally indicates concentration dependent in vitro effects observed across micromolar to low millimolar exposure ranges depending on cell type, medium composition, and endpoint selection, while precise potency metrics such as IC50 or EC50 are often assay specific and not universally standardized for this reagent class; accordingly, activity is best interpreted in interval based terms from low micromolar to higher micromolar or millimolar conditions under controlled experimental settings. Typical applications include use in cell culture models to study metal responsive gene expression, oxidative and inflammatory stress coupling to trace element status, host pathogen interaction assays, and biochemical or protein level experiments requiring controlled zinc supplementation, as well as use in animal research on systemic metal metabolism where dosing frameworks vary by model, route, and study duration, and the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
