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

Antimicrobial resistance (AMR) poses a significant global health threat, with multidrug-resistant pathogens undermining the effectiveness of conventional antibiotics. Natural alkaloids, a diverse group of nitrogen-containing compounds mainly derived from plants, are gaining attention as potential antimicrobial agents due to their broad-spectrum activity, structural variety, and unique mechanisms of action. This review examines the antimicrobial properties of natural alkaloids, classifying them by chemical structure (e.g., quinoline, isoquinoline, pyridine, indole, and imidazole alkaloids). Their antibacterial, antifungal, and antiviral activities are discussed, along with the mechanisms by which they target pathogenic microorganisms, including disruption of cell walls and membranes, inhibition of protein synthesis, interference with DNA replication, and viral assembly. The review also explores the synergistic effects of alkaloids when combined with conventional antimicrobial agents. Alkaloids demonstrate potent antimicrobial activity against various pathogens. Quinoline alkaloids, such as quinine, inhibit DNA replication and damage cell membranes. Isoquinoline alkaloids like berberine and sanguinarine exhibit broad-spectrum antibacterial effects. Pyridine alkaloids, including nicotine, disrupt bacterial membranes. In fungi, alkaloids such as sanguinarine and indole derivatives prevent cell wall synthesis and spore germination. Antiviral alkaloids like lycorine target viral RNA polymerases. Additionally, alkaloids enhance the activity of traditional antibiotics by overcoming resistance. Natural alkaloids represent a promising source of antimicrobial agents with diverse mechanisms to combat AMR. Future research should focus on optimizing alkaloid structures, ensuring safety and efficacy, and exploring combination therapies to address the escalating AMR challenge.
