Pyrazine bag se yon eleman nan konpoze divès kalite polyklik nan enpòtans endistriyèl ak byolojik. Manm enpòtan nan pyrazin fanmi yo se fenazin, aloksazin, ak pteridines. Pharmacologically ak byolojik, dyazin ki pi enpòtan yo se pyrimidines. Cytosine, timin, ak uracil se 3 nan baz nukleotid 5 ki konstitye kòd jenetik la nan RNA ak ADN. Anba a se estrikti yo:

Pyrazine ring is a component of various polycyclic compounds of industrial and biological importance. Important members of pyrazine family are phenazines, alloxazines, and pteridines. Pharmacologically and biologically, the most crucial diazines are pyrimidines. Cytosine, thymine, and uracil are the 3 of the 5 nucleotide bases which constitute the genetic code in RNA and DNA. Below are their structures:
