Diarylidene-N-Methyl-4-Piperidones and Spirobibenzopyrans as Antioxidant and Anti-Inflammatory Agents.
Article in Chemistry & biodiversity, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Curcumin has antioxidant properties resulting from its radical scavenging ability and inhibition of inflammation-associated factors. However, its lack of solubility, instability, and poor bioavailability are impediments to its therapeutic use. As potential alternatives, we synthesized and performed chemical analysis of thirty diarylidene-N-methyl-4-piperidone (DANMP), diheteroarylidene-N-methyl-4-piperidone (DHANMP), and spirobibenzopyran (SBP) derivatives, one of which was also characterized by single crystal X-ray diffraction. All compounds were evaluated for antioxidant activity via 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and for drug-like properties in silico. A subset of five compounds was investigated in terms of aqueous solubilities, which were significantly improved compared to that of curcumin. In vitro assessments of cellular and anti-inflammatory effects were conducted via real time polymerase chain reaction (RT-PCR) and Griess assays to evaluate the presence of inflammatory/activated (M1) markers and production of nitric oxide (NO) species, which are associated with inflammation. The five compounds reduced levels of markers and NO to extents similar to or better than curcumin in inflamed cells, and showed no adverse effects on cell viability. We show that these compounds possess anti-inflammatory properties and may be used as curcumin-substitutes with improved characteristics.
