Deep-Learning Driven Identification of Novel Antimicrobial Peptides.
Article in Chemistry (Weinheim an der Bergstrasse, Germany), 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
In this study, we report the identification of novel antimicrobial peptides (AMPs) via a machine learning-driven pipeline. Short Trp-rich peptide sequences were obtained using the HydrAMP deep learning (DL) algorithm, followed by the in silico screening for antimicrobial activity via the AMPlify DL model. Three candidates, namely AMP1, AMP2, and AMP3, were selected for synthesis and experimental validation. The antimicrobial activity was evaluated in vitro against a panel of Gram-positive and Gram-negative bacterial strains. Among them, AMP3 demonstrated the broader antibacterial spectrum. To investigate the mechanisms of action, we conducted detailed biophysical analyses of AMP3 interaction with liposomal models of bacterial membranes. The data revealed significant perturbation of membrane bilayer stability, supporting the proposed membrane-targeting activity of AMP3. Overall, our results underscore the potential of DL approaches for the accelerated discovery and mechanistic characterization of novel AMPs.
