The book entiled "Biological importance and synthetic overview on Imidazole hybrids'' describes biological studies and synthesis of imidazole hybrids. Nitrogen containing heterocycles are present in large number of biologically as well as medicinally potent molecules. Among five-membered heterocycles, imidazole has many pharmacological properties like anticancer, antibacterial and antifungal, antitubercular, anti-inflammatory, antioxidant, anti-depressant, anti-parasitic, antiviral, anti-leishmanial and anti-toxoplasmic activity. Further, the imidazole synthesis reactions are also incorporated in this.
