Pyrazolopyrimidine scaffolds are one of the most important heterocyclic compounds in drug discovery. This scaffold has various biological activities, among which anticancer is an important one.
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.
