Pyridazine, also known as o-diazobenzene, is a six-membered heterocyclic compound containing two nitrogen heteroatoms in the 1 and 2 positions with a special structure and a wide biological activity. Pyridazine is more and more popular in drug development, and a variety of pyridazine drugs have been developed and marketed. From the perspective of the therapeutic field, pyridazine drug molecules are mainly used for tumor treatment, but also involve in many therapeutic fields such as inflammation, hypertension and cardiovascular disease. With the increase and in-depth of research, pyridazine drugs will play more roles in the treatment of diseases.
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.
Triazole refers to a heterocyclic compound with the molecular formula C2H3N3, which has a five-membered ring consisting of two carbon atoms and three nitrogen atoms. Neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease already affect many people around the world, and these numbers are increasing rapidly. Treatment for these disorders is often aimed at relieving symptoms and has no cure. Research on new molecules is underway, and heterocyclic compounds have important pharmacological implications. Triazoles and tetrazoles are emerging as new molecules in this field.
