Article in Current organic synthesis, 2026. 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
introductionSulfonamide compounds are widely used in pesticide chemistry. This study aims to synthesize novel diphenyl sulfonamide derivatives with improved pesticidal properties. MATERIALS AND
methodsFifty-five diphenyl sulfonamide derivatives were designed and synthesized using Suzuki, Wittig, and Sonogashira couplings, as well as propargyl etherification. The compounds were characterized by spectroscopic techniques, and their insecticidal activities against Mythimna separata were evaluated. Their mechanisms of action were further explored through electrophysiological tests using a Drosophila melanogaster model and molecular docking analyses.
resultsCompounds S6-3 and S6-4 demonstrated high insecticidal activity, with LC50 values of 0.474 and 0.401 mg/mL, respectively, both superior to L-1. S6-4 affected Drosophila melanogaster neuromuscular junctions in a manner similar to bafilomycin A1, and molecular docking indicated binding to the H subunit of V-ATPase. DISCUSSION: Structure-activity relationship analysis revealed the key structural features influencing insecticidal activity, providing guidance for further compound optimization.
conclusionThe synthesized derivatives targeting V-ATPase exhibited potent insecticidal activity and showed strong potential for the development of novel pesticides.
