Synthesis of Benzopyrans and Quinolines with Nitrogenated Chain and Their Cytotoxicity Against Human Cancer Cell Lines.
Article in ChemMedChem, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Cancer caused 9.9 million deaths in 2020, and natural products and/or their structural analogs represent the greatest number of approved small-molecules antitumor agents. Benzopyran and quinoline heterocycles have demonstrated cytotoxic activity against different cancer cell lines. Due to its high therapeutic potential, we report the synthesis of 2-propanamide- and 2-propanamine-dihydrobenzopyrans bearing different amine moieties in the side chain, as well as the 7-carbon prenylated derivatives (analogous to natural polyalthidin). Next, we synthesized the 2-substituted and 2,3-disubstituted quinolines as benzopyran analogs. We evaluated the cytotoxic activity of all nitrogenated derivatives against human cancer cell lines, including A549 (lung cancer), A2058 (melanoma), HepG2 (hepatocellular carcinoma), MCF-7 (breast cancer), and Mia PaCa-2 (pancreas cancer) by the MTT assay. Structure-activity relationship analysis revealed: (i) the benzopyran core was twofold more cytotoxic than quinoline analogs and reached ED
