The Biological Activity of Selenium Sulfide

Abstract

The history of selenium sulfide and its chemical nature as a discrete compound are discussed together with its uses within the medical field of dermatology. Evidence for its effects on biological systems are presented and potential mechanisms of action via its antimicrobial activity, effects on cell growth and its role as a catalyst in the enhancement of the activity of sulfur are critically reviewed.

High-efficient photocatalytic treatment of dye and anti-bacterial activity via electrochemically synthesized SeS2nanoparticles

“…Based on literature reports, the chemical kinetic of catalytic dye oxidation in liquid systems can be described by a first-order model. [12] 3.…”

“…[10] SeS 2 is most highly exploited for its biological activity but its capability as a photocatalyst is very less studied. [11,12] Semiconductor SeS 2 nano photocatalyst can use the available source of ultraviolet (UV) radiation from sunlight or artificial light and conduct a chemical reaction to degrade the organic pollutant present in both the liquid and gaseous phases. [13][14][15] However, the need for UV radiation in photodegradation processes has limited both the practicality and environmental benefits on industrially relevant scales.…”

The elimination of selenium(IV) from aqueous solution by precipitation with sodium sulfide

“…In the medical field however, selenium disulfide is prepared by fusing selenium and sulfur at a ratio of 1:2 and not from an aqueous route. Medical literature also generally specifies that selenium disulfide is composed of a mixture of selenium monosulfide existing in equilibrium with a sulfur selenium solid solution [24,25]. It is worth noting that while selenium disulfide has been used for decades in the pharmaceutical industry, selenium monosulfide has recently been classified as carcinogenic [26].…”

Scalp Discoloration from Selenium Sulfide Shampoo: A Case Series and Review of the Literature

“…Increased epidermal proliferation, parakeratosis, and follicular plugging are seen histologically in seborrheic dermatitis (17). Selenium sulfide has been shown to have cytostatic effects on hyperproliferative keratinocytes (18) and keratolytic effects via hydrogen sulfide formation upon interaction with keratinocytes (19).…”
