Repurposing Etalocib suppresses multidrug-resistant Staphylococcus aureus by disrupting the bacterial membrane.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundThe emergence of multidrug-resistant (MDR) Staphylococcus aureus (S. aureus) seriously poses a serious threat to human health and presents a significant clinical challenge. Therefore, it is urgent to explore alternative treatments and develop novel antimicrobial agents. To investigate the antibacterial activity of Etalocib against S. aureus and elucidate its underlying mechanism of action.
resultsEtalocib, a drug previously investigated in clinical trials, exhibited notable antibacterial activity against S. aureus, with a minimum inhibitory concentration (MIC) of ≤ 25 μM. Time-kill curves demonstrated concentration-dependent bactericidal effects. Etalocib could significantly inhibited biofilm formation and kill bacteria within mature biofilms. Moreover, permeability assays revealed that Etalocib treatment caused bacterial membrane damage, accompanied by dissipation of membrane potential. Checkerboard analysis showed that bacterial membrane phospholipids, including phosphatidylglycerol and cardiolipin, could neutralize the antibacterial activity of Etalocib in a dose-dependent manner. These findings suggest that the primary mechanism of action involves disruption of the bacterial membrane, potentially through interactions with membrane phospholipids, alterations in protein homeostasis, and disturbances in energy and metabolic processes. Notably, Etalocib significantly improved the survival rate of the Galleria mellonella in the methicillin-resistant S. aureus (MRSA) infection model.
conclusionsThe findings highlight the potential of Etalocib as an effective antibacterial agent for combating MDR S. aureus infections. It holds significant promise as a novel therapeutic option for the treatment of severe infections caused by Gram-positive pathogens.
