Experimental, spectroscopic, thermodynamic, and DFT study of a novel cyanomethylchrome nopyridinecarbonitrile (CCPC).
Article in Scientific reports, 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
A novel heterocyclic system, 5-cyanomethylchromeno[4,3-b]pyridine-3-carbonitrile (CCPC, 3), was synthesized via the reaction of 3-(6,8-dimethylchromonyl)acrylonitrile (1) with cyanoacetamide (2) under basic conditions. The transformation proceeds through a cascade mechanism involving Michael addition, γ-pyrone ring opening, and double recyclization. The structure of CCPC was confirmed by analytical and spectral data. Density functional theory (DFT/B3LYP/6-311 + + G(d, p)) was used to optimize its molecular geometry and investigate electronic properties, global reactivity descriptors, molecular electrostatic potential, and intramolecular charge transfer characteristics. Thermokinetic behavior was evaluated using KiSThelP, while UV–Vis spectra were simulated via TDDFT, showing solvent-dependent absorption shifts. SwissADME analysis indicated favorable drug-likeness according to Lipinski’s and Veber’s rules. Overall, the combined experimental and computational study provides insight into the structure, reactivity, stability, and potential applications of CCPC.
