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.
Phenanthrene is a crystalline tricyclic aromatic hydrocarbon with the molecular formula C14H10. The centers of the three rings of phenanthrene are not in a straight line and are the isomers of anthracene. In medicine, phenanthrene can synthesize alkaloids. Although phenanthrene is considered a relatively small natural product, discovering new phenanthrene derivatives and evaluating their potential biological activity has become of great interest to many research groups worldwide.
