1 · What the graph read from it

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.

2 · The registry

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

Flavonoids and stilbenes are phenylpropanoid-derived secondary metabolites found in plants, fungi, and microorganisms. They serve important physiological functions and offer a range of pharmacological benefits, including antioxidant, anti-inflammatory, anticancer, and antimicrobial effects. However, many native flavonoids and stilbenes have limited pharmacology and industrial use due to poor bioavailability and low metabolic stability. O-methylation is a key post-biosynthetic modification that improves the physicochemical and pharmacokinetic properties of these compounds. This process, catalyzed by S-adenosyl-L-methionine [SAM]-dependent O-methyltransferases [OMTs], increases lipophilicity, chemical stability, and membrane permeability, often resulting in greater bioactivity. As a result, methylated derivatives such as sakuranetin, acacetin, isorhamnetin, and pterostilbene frequently show enhanced therapeutic efficacy, even though they are less abundant in nature. Advances in metabolic engineering and synthetic biology have enabled efficient biosynthesis of methylated flavonoids and stilbenes in microbial hosts such as Escherichia coli, Saccharomyces cerevisiae, and Streptomyces species. Strategies including pathway optimization, SAM regeneration, enzyme engineering, and CRISPR-based genome editing have significantly improved production yields and regioselectivity, with some systems surpassing native producers. Despite this progress, challenges remain in enzyme specificity, metabolic bottlenecks, and downstream processing. This review summarizes recent developments in understanding methylation biosynthetic pathways, OMT diversity, and microbial engineering strategies. It also highlights the pharmacological significance of methylation and the potential of engineered microbial platforms for sustainable, scalable production of methylated flavonoids and stilbenes for pharmaceutical and nutraceutical use.
