QUINOLINE: A VERSATILE HETEROCYCLIC

Heterocyclic are abundant in nature and are of great significance to life because theirstructural subunits exist in many natural products such as vitamins, hormones, antibiotics and alkaloids, as well as in pharmaceuticals, herbicides, dyes, and many more compounds.1These heterocyclic have great importance in drug discovery as theheteroatoms present in them make hydrogen bonds with the receptors present in thebody and thus giving their significant pharmacological actions. Out of severalheterocyclic compounds, those with Nitrogen atom in their structure give promisingpharmacological activities. According to the literature quinoline and piperazine derivatives are one of the emerging drugs of therapeutic importance showing a widespectrum of biological activities which are discussed here in this chapter.
