Generally pyrimidine derivatives such as 2-hydroxy-substitutedpyrimidine, 2-mercapto-substituted-pyrimidine and 2-amino-substituted pyrimidine are studied. Pyrimidines have been isolated from the nucleic acid hydrolysates. Pyrimidines are among those molecules that make life possible, have been some of the building blocks of DNA and RNA. Several analogues of pyrimidines have been used as compounds that interfere with the synthesis and functioning of nucleic acids e.g. fluorouracil, which has been used in cancer treatment. Modifications in the base, sugar and phosphate moieties of...

The actions of many infectious diseases are demanding due to fighting to antimicrobial agents. The emergence of fighting among bacteria to a wide variety of structurally unrelated antibacterial agents such as 6-lactams, macrolides, tetracyclines and fluoroquinolones as well as selected dyes and disinfectants has become a serious public health concern so makes it necessary to continue the search for new antibacterial agents. In recent scenario heterocycles is the different rule in drug synthesis. In that respect pyrimidine plays a significant rule among other heterocycles. From the literature...
