Valgamicin C, a novel cyclic depsipeptide containing the unusual amino acid cleonine, and related valgamicins A, T and V produced by Amycolatopsis sp. ML1-hF4.

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.
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
In the course of optimizing pargamicin A production in Amycolatopsis sp. ML1-hF4, we discovered novel cyclic depsipeptide compounds in the broth and designated them valgamicins A, C, T and V. The structures of these molecules were determined by spectroscopic studies, advanced Marfey's method and X-ray crystal structural analysis. Valgamicin C contains the extremely rare amino acid cleonine. To our knowledge, this is the first report of a cleonine-containing metabolite from a naturally isolated microorganism without any breeding or mutation treatment. None of the valgamicins showed potent antibacterial activity against either Gram-positive or -negative bacteria. Valgamicins A, C and T exhibited moderate cytotoxicity against human tumor cell lines.The Journal of Antibiotics advance online publication, 15 November 2017; doi:10.1038/ja.2017.135.
