Discovery of Pyrazoline Benzenesulfonamide Derivatives as Anticancer Agents: A Review.
Review in Drug design, development and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Pyrazoline benzenesulfonamide derivatives represent a distinctive class of heterocyclic compounds that synergistically combine the pharmacological versatility of the pyrazoline scaffold with the enzyme-inhibitory prowess of benzenesulfonamide moieties. These hybrids have emerged as promising candidates in anticancer drug discovery. This review systematically examines various synthetic strategies employed to prepare these derivatives, including classical Claisen-Schmidt condensation as well as modern ultrasound- and microwave-assisted protocols. These methods facilitate efficient structural diversification, incorporating a wide range of heterocyclic and aromatic substituents such as morpholine, pyrazole, benzodioxole, tetrazole, and ferrocene. Biological evaluations, integrating both in vitro cytotoxicity assays and in silico molecular docking studies, were analyzed to elucidate the anticancer potential and mechanistic insights of these compounds, particularly their selective inhibition of tumor-associated enzymes such as matrix metalloproteinases (MMP-2, MMP-9), carbonic anhydrase isoforms (hCA IX, hCA XII), and cyclooxygenase-2 (COX-2). The results reveal that several derivatives exhibit potent antiproliferative activity across multiple cancer cell lines, including lung (A549), breast (MCF-7), cervical (HeLa), colon (COLO 205), and oral squamous carcinoma, demonstrating significant tumor selectivity and low toxicity toward normal cells. Structure-activity relationship analyses further underscore the critical influence of electronic substituents and their positioning on aromatic rings in modulating both efficacy and selectivity. These findings highlight the therapeutic potential of pyrazoline benzenesulfonamide derivatives and support the continued optimization of synthetic strategies and mechanistic studies to facilitate their development as effective anticancer agents capable of overcoming clinical challenges such as drug resistance and adverse side effects.
