In vitro cytotoxic mechanisms of Pt(O,O'-acac)(γ-acac)(DMS): mitochondrial dysfunction and impaired autophagy in U251 cell line.
Article in Cell death discovery, 2026. 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
Glioblastoma stands as the deadliest primary brain malignancy in adults, primarily due to its resistance to conventional treatments and the restrictive nature of the blood-brain barrier (BBB). Cisplatin (CDDP), a widely used chemotherapeutic, demonstrates limited efficacy against glioblastoma owing to systemic toxicity and insufficient BBB penetration. To overcome these hurdles, we tested the platinum(II) complex [Pt(O,O'-acac)(γ-acac)(DMS)], indicated as Pt(acac)₂(DMS), known for its improved lipophilicity, ability to disrupt mitochondrial function, and reduced neurotoxic profile. Compared to CDDP, Pt(acac)₂(DMS) induced a targeted and prolonged cytotoxic response in U251 glioblastoma cells, promoting mitochondrial dysfunction, cell cycle arrest, and modulation of autophagy, while sparing primary human astrocytes. Our findings indicate that Pt(acac)₂(DMS) may overcome key limitations of cisplatin, including toxicity issues and resistance associated with autophagic adaptation, highlighting its promise as a potential therapeutic candidate for glioblastoma treatment.
