**Abstract**

Heterocyclic compounds have an essential role in many domains of medicinal chemistry. Many pharmaceutical industries use and investigate nitrogen-containing heterocycles because they are crucial in discovering and developing novel therapeutically active compounds. The benzimidazole moiety is a fundamental component of many heterocyclic scaffolds, which play an important role in producing a wide range of biological activities. Similarly, quinoline is also a versatile bicyclic heterocyclic scaffold with many medicinal applications. It is an essential scaffold for drug discovery leads, and it plays a significant role in medicinal chemistry and has biological activities similar to benzimidazole scaffolds. The present chapter discusses the quinoline-benzimidazole hybrids scaffolds and their potential pharmacological activities.

**Keywords:** quinoline, benzimidazole, hybrid molecules, synthesis, pharmacological activity
