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

Septacidin is an adenine nucleoside antibiotic with antifungal and antitumor activities. During the efforts to construct a better septacidin producer, we obtained a high yield strain S. albus 1597 by putting the biosynthetic gene cluster (BGC) of septacidin under the control of the constitutive strong promoter ermE*. S. albus 1597 could produce new septacidin congeners SEP-538 and SEP-552 with shorter fatty acyl chains. Moreover, SEP-624 with an unprecedented hydroxylated fatty acyl chain was also isolated from this titre improved strain, enriching the diversity of septacidins. SEP-552 showed moderate inhibitory effects against Epidermophyton floccosum 57312 with MIC value 62.5 μM, while SEP-538 and SEP-624 only exhibited weak antifungal activities. The structure-activity relationship investigation revealed that the antifungal activity of septacidins is significantly influenced by the length of and the decoration on their fatty acyl chains.
