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

Selective access to a targeted isomer is often critical in the synthesis of biologically active molecules. Whereas small-molecule reagents and catalysts often act with anticipated site- and stereoselectivity, this predictability does not extend to enzymes. Further, the lack of access to catalysts that provide complementary selectivity creates a challenge in the application of biocatalysis in synthesis. Here, we report an approach for accessing biocatalysts with complementary selectivity that is orthogonal to protein engineering. Through the use of a sequence similarity network (SSN), a number of sequences were selected, and the corresponding biocatalysts were evaluated for reactivity and selectivity. With a number of biocatalysts identified that operate with complementary site- and stereoselectivity, these catalysts were employed in the stereodivergent, chemoenzymatic synthesis of azaphilone natural products. Specifically, the first syntheses of trichoflectin, deflectin-1a, and lunatoic acid A were achieved. In addition, chemoenzymatic syntheses of these azaphilones supplied enantioenriched material for reassignment of the absolute configuration of trichoflectin and deflectin-1a based on optical rotation, CD spectra, and X-ray crystallography.
