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

Spiroacetal compounds are ubiquitous in nature, and their stereospecific structures are responsible for diverse pharmaceutical activities. Elucidation of the biosynthetic mechanisms that are involved in spiroacetal formation will open the door to efficient generation of stereospecific structures that are otherwise hard to synthesize chemically. However, the biosynthesis of these compounds is poorly understood, owing to difficulties in identifying the responsible enzymes and analyzing unstable intermediates. Here we comprehensively describe the spiroacetal formation involved in the biosynthesis of reveromycin A, which inhibits bone resorption and bone metastases of tumor cells by inducing apoptosis in osteoclasts. We performed gene disruption, systematic metabolite analysis, feeding of labeled precursors and conversion studies with recombinant enzymes. We identified two key enzymes, dihydroxy ketone synthase and spiroacetal synthase, and showed in vitro reconstruction of the stereospecific spiroacetal structure from a stable acyclic precursor. Our findings provide insights into the creation of a variety of biologically active spiroacetal compounds for drug leads.
