Heterocyclic Chemistry is the backbone of medicinal compounds that exhibits numerous biological activities. Pyrazole and its derivatives possess nitrogen atom along with carbon atom as a substitution and show a diversity of biological activities such as antibacterial, antimicrobial, anti-inflammatory, antioxidant, antidiabetic, anticancer, antifungal, antidepressant, anticonvulsant, analgesic, and monoamine oxidases (MAOs)as shown by pyrazoline prepared from chalcone(Intermediate). The synthesized compounds are checked by the TLC and further analyzed by the IR, NMR, and UV spectroscopy.
