1 · What the graph read from it

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.

2 · The registry

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

Cancer treatment is challenging, mainly due to high levels of drug toxicity and the resistance of tumours to chemotherapy. Hydroxamic acid derivatives have recently aroused attention due to their potential to treat malignancies. In the present study, we sought to investigate the anticancer effects of a new series of synthetic acetohydroxamates. The in vitro cytotoxic and antiproliferative effects of 11 synthetic acetohydroxamates were evaluated against the melanoma cell line A375. Apoptosis, cell cycle, and autophagy assays were employed to elucidate the cell death pathways induced by the compounds. The in vivo pharmacokinetic profiles of the most promising compounds were determined in CD-1 mice, while the in vivo antitumour efficacies were evaluated using the A375 melanoma xenograft model in nude mice. MTT assays revealed that all compounds presented concentration-dependent cytotoxicity against the A375 cell line. AKS 61 produced the most favourable antiproliferative activity according to the sulphorhodamine B and clonogenic assays. AKS 61 treatment resulted in decreased mitochondrial membrane potential and increased apoptosis and autophagy in the A375 cell line. However, AKS 61 failed to prevent in vivo tumour growth in a melanoma xenograft, whereas compound AKS 7 was able to inhibit tumour growth when administered orally. These in vivo findings may be explained by a more favourable pharmacokinetic profile presented by AKS 7 when compared to AKS 61. Taken together, these results suggest that acetohydroxamates have potential anticancer effects and will guide future optimisation of these molecules to allow for further non-clinical development.
