The use of azepane as a scaffold for drug discovery remains of interest. The azepane linker is the key to efficient activity. A number of seven-membered ring derivatives have been prepared or investigated for their potential or actual pharmacological properties. Examples include azaalkane derivatives as PKB (protein kinase B) inhibitors.
Benzoxazines are a type of heterocyclic compounds consisting of benzene and oxazine rings. Benzoxazine research is developing rapidly because of the many potential applications of the materials.
