One-pot synthesis of substituted pyrrole-imidazole derivatives with anticancer activity.

A facile and efficient method to synthesize pyrrole-imidazole was developed via a post-Ugi cascade reaction followed by one purification procedure. Synthesized pyrrole-imidazole was collected by performing a mild reaction and a simple procedure, which could be applicable to a broad scope of functionalized anilines. The screening results demonstrated that compound 7e exhibited a high potency of anticancer activity in human pancreatic cancer cell lines PANC and ASPC-1. Our work shed light on the potential of post-Ugi cascade reaction in combinatorial and medicinal chemistry.
