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

Waixenicin A (WaixA) is a marine natural product that has emerged as a potential drug lead for the treatment of hypoxic ischemic brain injury. WaixA specifically blocks the divalent ion channel transient receptor potential melastatin 7 (TRPM7), preventing the influx of calcium into the cell and triggering apoptotic pathways. We applied pharmacophore-directed retrosynthesis to this natural product, leading us to prepare a series of highly simplified derivatives bearing our proposed minimal pharmacophore, namely, the pyranyl vinylogous acetal. The synthesis of these derivatives and their ability to inhibit TRPM7 is described. Inhibition in the 9-57% range was found for these simplified structures in patch-clamp experiments; however, the ability of these highly simplified derivatives to exhibit inhibition provides information regarding minimal structural requirements for bioactivity.
