Abstract

Despite the continued efforts and advancements in anti-cancer drug discovery, cancer is still considered as one of the leading causes of mortality globally. Hence, the discovery of novel chemotherapeutic agents that displayed a prominent effect against cancer is a pressing need. In this study, an expeditious cascade was used to access a pilot library of indolopyrazine fused to imidazole and pyrimidinone heterocyclic scaffolds. The synthetic strategy utilized a cascade reaction that combined Mannich with aza-Michael addition reactions followed by coupling with a variety of amines. Phenotypic screening of the developed library against HCT116 colon and MCF-7 breast cancer cell lines identified chemotypes that formed the basis for hit-to-lead development of anti-cancer agents. The intriguing architecture and scope of functional variability of these types of pentacyclic molecules made them appropriate motifs for the development of lead drug candidates.
