Abstract
Aims:
The study aims to synthesize hybrid molecules containing pyrazole and aryldiazenyl/arylhydrazono
fragments with promising anticancer activity.
Background:
The clinical effectiveness of anticancer drugs is limited by their adverse side effects and patient resistance.
Therefore, the development of safer classes of drugs through rational drug design is imperative.
Objective:
Considering the anticancer potential of the pyrazole moiety, the study was carried out with the objective of
synthesizing some hybrid pyrazole derivatives with anticancer potential.
Method:
The anticancer potential of these pyrazolyl analogues were evaluated by sulforhodamine B assay using three
cancer cell lines MCF-7, HepG2, and HCT-116.
Result:
HCT-116 was the most sensitive cell line against these pyrazolyl analogues. Among these newly synthesised
derivatives, 1-(4-((4-bromophenyl)diazenyl)-3,5-dimethyl-1H-pyrazol-1-yl)-2-(naphthalen-2-yloxy)ethan-1-one (5e)
emerged as a promising anticancer agent (IC50 3.6-24.6 μM), having a xanthine oxidase inhibitory effect (IC50 10.87
μM). To obtain further insights into the binding interactions of these molecules, molecular docking studies were also
carried out.
Conclusion:
In summary, our findings suggest that these hybrid pyrazolyl derivatives can be considered as potential
lead molecules for anticancer agents.
