Piperazine is an organic compound consisting of a six-membered ring containing two nitrogen atoms in opposite positions in the ring. The chemical formula of piperazine is C4H10N2, and it is an important pharmaceutical intermediate. Pyrimidines and piperazines are known to be the backbone of many bulk compounds and important core structures for approved drugs; studies have shown that combining a pyridine ring with a piperazine moiety within a single structural framework enhances biological activity.
Triazines are an important class of six-membered aromatic heterocycles with three nitrogen atoms that give rise to three regioisomers: 1,2,4-triazines, 1,2,3-triazines, and 1,3, 5-triazine. 1,2,3-Triazines show remarkable reactivity and have attracted attention for their medicinal value. Triazine compounds fused with other carbon and heterocycles are stable and have a broad spectrum of pharmacological activities.
