Recent updates in medicinal chemistry and SAR profile of therapeutically important pyrazole hybrid analogues...

Pyrazole motif is a privileged heterocyclic scaffold in drug discovery owing to its conformational rigidity, hydrogen-bonding potential and favorable pharmacokinetic properties. Pyrazole analogues possess numerous pharmacological effects including anticancer, antimicrobial, antidiabetic and anti-inflammatory actions etc. Also, favorable substitution pattern in published pyrazoles works as a suitable rationale to design and develop novel pyrazolyl analogues with improved therapeutic efficacy and lesser extent of toxicity. The present review focuses on following major outcomes: 1) To emphasize keen biological potential of pyrazole-based molecules with potent antimicrobial, anticancer, anti-inflammatory, antidiabetic and many more activities; 2) To compile recent literatures (2022-2025) that are dedicated toward therapeutic potential of pyrazole or pyrazolyl hybrid analogues; 3) To explore structure-activity relationship data in order to correlate structural features of most active molecules with promising therapeutic outcomes; 4) Several series demonstrated low-micromolar to nanomolar potency corroborated by docking and ADMET predictions to underscore role of computational approaches in validating binding hypotheses. This article consolidates advances in biological evaluation and in silico studies of therapeutically relevant pyrazole derivatives along with SAR highlights. The insights emphasize need for more holistic pipelines to combine green synthesis, predictive computational modeling and mechanistic biological validation in future to accelerate transition of pyrazole-based leads.
