GENERAL DESCRIPTION & APPLICATIONS
Pyridinethione inhibits the growth of fungi, yeast, mold and bacteria. Sodium and zinc salt of pyrithione N-oxide are widely used in cosmetics and shampoo. In acidic media, amine N-oxides are cationic and can act as a mild conditioner.They are used in body care products. Pyridinethione derivatives, belong to a class of cyclic sulfur organo products containing sulfur atom (S) and often oxygen (O), nitrogen (N), hydrogen (H), as well as other elements, can find application for making biologically active agents such as antiviral, antibacterial, antifungal , antituberculous, antbody and antifungal agents. Pyrimidine is a heterocyclic compound containing nitrogen atoms at positions 1 and 3 in six-membered ring structure molecule. The three major pyrimidines in living systems are cytosine, thymine, and uracil. Pyrimidine and its derivatives are biologically important components of nucleic acids (DNA, RNA) and coenzymes. They can be the parent compound of many drugs, including the barbiturates.
