Isofloridoside: a novel inhibitor of Streptococcus mutans biofilm formation and glucosyltransferase activity.
Article in BMC research notes, 2025. 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
objectiveIsofloridoside, a galactose-containing heteroside derived from marine red algae, has potential applications as a sweetener because it can activate the sweetness receptors T1R2/T1R3. The purpose of this study was to investigate the effects of isofloridoside on the growth and sucrose-dependent biofilm formation of the cariogenic bacterium Streptococcus mutans, to evaluate its potential as a caries-preventing agent.
resultsThe results showed that S. mutans did not grow when isofloridoside was the sole carbon source. Isofloridoside inhibited sucrose-dependent biofilm formation by S. mutans in a concentration-dependent manner, similar to galactose and glucose, but unlike melibiose and galactose-containing disaccharides. Biofilm inhibition induced by isofloridoside was associated with inhibition of glucosyltransferase activity. Isofloridoside exhibited biofilm inhibition comparable to xylitol, an alternative sugar known to inhibit biofilm formation. The differential effects of isofloridoside and melibiose on biofilm formation may result from the structural differences that affect their interactions with S. mutans enzymes. These findings highlight the potential of galactose and its polysaccharides as regulators of S. mutans biofilm formation, and suggest that isofloridoside is a promising alternative sweetener for caries prevention.
