Synthesis and Antitumor Activity of Some New
Article in Current organic synthesis, 2024. 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
backgroundHydrazonoyl chloride, accessible from the respective 5-amino-8-fluoro- 4-oxoquinoline-3-carboxylate, undergoes a reaction with sec-cyclic amines to generate N1-(1- ethyl-8-fluoro-4-oxoquinolin-5-yl)amidrazone carboxylates.
introductionA novel set of N1-(1-ethyl-8-fluoro-4-oxoquinolin-5-yl)amidrazone carboxylates (7a-h) incorporating N-piperazines or related congeners was synthesized
aimsThis study aimed at the synthesis of novel N1-( 4-oxoquinolin-5-yl)amidrazone carboxylate derivatives and investigated their potential as anticancer agents.
objectiveThe reaction of hydrazonoyl chloride with the appropriate sec-cyclic amine was applied to synthesize a novel set of N1-(1-ethyl-8-fluoro-4-oxoquinolin-5- yl)amidrazone carboxylates that incorporate N piperazines.
methodsA direct reaction of piperazines and related sec-cyclic amines with N-(4-oxoquinolin-5- yl)nitrile imine (1,3-dipole) was carried out for 8-10 h.
resultsThe 1,3-dipole, generated in situ from its hydrazonoyl chloride precursor in the presence of trimethylamine, is suitable for the facile synthesis of N1-(1-ethyl-8-fluoro-4-oxoquinolin-5- yl)amidrazone carboxylates.
conclusionThis study led to the successful synthesis of novel N1-(8-fluoro-4-oxoquinolin-5- yl)amidrazones. All the examined compounds showed moderate activity with reasonable IC50 values in the micromolar range compared to Doxorubicin.
