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.
Aziridines are highly strained three-membered heterocyclic molecules composed of one amine group and two carbon units. They are aza analogs of epoxides. Aziridines are a very important class of synthetic building blocks and intermediates in organic synthesis, which are widely used in organic synthesis, especially in the synthesis of nitrogen-containing natural products. Due to the high ring tension of aziridine, its reactivity is high. Under certain conditions, it can undergo cycloaddition reaction with various dipolar reagents to prepare some new nitrogen-containing heterocyclic compounds.
