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

Angucyclines and angucyclinones are aromatic polyketides with a tetracyclic benz[a]anthracene skeleton. The benz[a]anthracene scaffold is biosynthesized by type II polyketide synthases that catalyze the decarboxylative condensation of a short acyl-CoA starter and nine extender units. Angucyclines and angucyclinones, the largest group of polycyclic aromatic polyketides, achieve structural diversity via subsequent oxidation, ring cleavage, amino acid incorporation, and glycosylation. We here report the discovery of 14 angucyclinones and two angucyclines (1-16) from Streptomyces sp. CB01913, identifying 12 new compounds featuring various oxidations on rings A and C (1, 2, and 4), different sugar moieties attached to rings A and B (3 and 6), and C-ring cleavage (5 and 10-14) and expansion (8). These new structural features, highlighted by C-ring cleavage and expansion, enrich the structural diversity of angucyclines and angucyclinones. All compounds were tested for cytotoxicity and antibacterial activities, with 1, 5, 15, and 16 showing moderate activities against selected cancer cell lines or bacterial strains.
