Current Trends in Macrocyclic Drug Discovery and beyond-Ro5.

This chapter will discuss the recent literature of macrocycles and drug-like property space moving beyond the rule of five (bRo5). Trends in chemical classes that fall within this definition are discussed and the impact of the latest technologies in the field assessed. The physicochemical properties, which have provided both successes and challenges, especially in scale-up, are discussed. A recent patent literature is reviewed and the chapter concludes with a perspective on the future of macrocyclic drug discovery.
