Off-target effects of the NADPH oxidase inhibitor mitoapocynin-encapsulated nanoparticles and free-drug oral treatment in a rat DFP model of neurotoxicity.
Article in Journal of drug targeting, 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
Acute exposure to diisopropylfluorophosphate (DFP), an organophosphate (OP), produces chronic neurological effects such as spontaneous seizures and behavioural comorbidities. Achieving optimal drug bioavailability in the brain by conventional routes to treat OP-induced neurotoxicity is challenging. Therefore, we investigated polyanhydride nanoparticles (NPs)-mediated drug delivery via the intramuscular route in rats for improved bioavailability of an antioxidant, NADPH oxidase inhibitor mitoapocynin (MPO). We evaluated the tolerability of blank NPs (4 mg, i.m.), MPO-encapsulated NPs (MPO-NP, 4 mg, i.m., single dose) and free MPO-oral (60 mg/kg, daily for three days) after exposure to DFP. Bodyweight, serum biochemistry, and kidney, lung and liver histology revealed no adverse responses to blank NPs. Markers of oxidative stress, neuronal loss and astrocyte reactivity were also no different from control. In DFP-exposed animals treated with MPO-NP and MPO-oral, there was significant weight loss, abnormal liver and kidney parameters, and elevated GP91phox and astrocytes in the brain. Our findings demonstrate that NP delivery via the intramuscular route is safe. DFP and MPO induced off-target effects, but not DFP or MPO treatment alone, which highlights the complexity of dosing regimens in OP models. Intranasal MPO-NP delivery and dose optimisation in the DFP model are required to determine the efficacy of MPO in future studies.
