The pyrithione ligands, which are formally monoanions, are chelated to Zn 2+ via oxygen and sulfur centers. In the crystalline state, zinc pyrithione exists as a centrosymmetric dimer (see figure), where each zinc is bonded to two sulfur and three oxygen centers. [3] In solution, however, the dimers dissociate via scission of one Zn-O bond ...
Pyrithione is the common name of an organosulfur compound with molecular formula C 5 H 5 NOS, chosen as an abbreviation of pyridinethione, and found in the Persian shallot. [4] It exists as a pair of tautomers, the major form being the thione 1-hydroxy-2(1H)-pyridinethione and the minor form being the thiol 2-mercaptopyridine N-oxide; it crystallises in the thione form.

It's powered by pyrithione zinc, an ingredient Kobets say works very well to soothe a dry scalp and provide itch relief. ... "Containing both zinc omadine and coal tar, this high-end shampoo also ...
Imidazole antifungals. Only a few imidazole antifungals are effective against seborrheic dermatitis. Ketoconazole was found to be the most active against Pityrosporum ovale. It is available in both oral and topical formulations. It is also available as cream, gel and tablet. Unlike other drugs, it does not cause skin irritation or phototoxicity.
Piroctone olamine is the ethanolamine salt of the hydroxamic acid derivative piroctone was first synthesized in 1979 by Schwarzkopf-Henkel (Germany). It is often used in anti- dandruff shampoo as a replacement for the commonly used compound zinc pyrithione which was banned in the EU in 2021 because of concerns for environmental toxicity.
Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
Zinc is an inexpensive and effective part of treatment of diarrhea among children in the developing world. Zinc becomes depleted in the body during diarrhea and replenishing zinc with a 10- to 14-day course of treatment can reduce the duration and severity of diarrheal episodes and may also prevent future episodes for as long as three months.

Organozinc chemistry. Organozinc chemistry is the study of the physical properties, synthesis, and reactions of organozinc compounds, which are organometallic compounds that contain carbon (C) to zinc (Zn) chemical bonds. [1][2][3][4] Organozinc compounds were among the first organometallic compounds made. They are less reactive than many other ...
