Broad-spectrum therapeutic potential of 4-phenylbutyrate in neurological and systemic diseases of viral and non-viral origin.
Review in Frontiers in pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
4-Phenylbutyrate (4-PBA), initially recognized for treating urea cycle disorders, has emerged as a potent therapeutic agent with broad-spectrum potential. As a chemical chaperone, 4-PBA modulates protein folding and reduces endoplasmic reticulum stress. 4-PBA has demonstrated efficacy in treating ocular herpes simplex virus type 1 (HSV-1) infection and HSV-1-induced encephalitis, highlighting its potential as a novel anti-herpetic therapy. Beyond its antiviral properties, 4-PBA's therapeutic reach extends to neurological disorders linked to HSV-1 infection, including Parkinson's, Alzheimer's, Huntington's diseases, and primary open-angle glaucoma. Furthermore, 4-PBA shows promise in treating a diverse array of conditions beyond neurology. Its potential has been explored in atherosclerosis, Adriamycin-induced cardiac injury, non-alcoholic fatty liver disease, rifamycin-induced liver injury, chronic kidney disease, diabetic nephropathy, NSAID-induced kidney injury, and chronic wound healing. This review synthesizes the multifaceted therapeutic potential of 4-PBA, emphasizing its role as a broad-spectrum agent capable of addressing a wide range of pathological conditions, particularly its role in combating HSV-1 and associated neurological disorders. The growing evidence suggests that 4-PBA may be a versatile and valuable addition to the therapeutic arsenal against multiple diseases.
