Total Synthesis of Lipopeptide Bacilotetrin C: Discovery of Potent Anticancer Congeners Promoting Autophagy.

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
A convergent strategy for the first total synthesis of the lipopeptide bacilotetrin C has been developed. The key features of this synthesis include Crimmins acetate aldol, Steglich esterification, and macrolactamization. Twenty-nine variants of the natural product were prepared following a systematic structure-activity relationship study, where some of the designed analogues showed promising cytotoxic effects against multiple human carcinoma cell lines. The most potent analogue exhibited a ∼37-fold enhancement in cytotoxicity compared to bacilotetrin C in a triple-negative breast cancer (MDA-MB-231) cell line at submicromolar doses. The study further revealed that some of the analogues induced autophagy in cancer cells to the point of their demise at doses much lower than those of known autophagy-inducing peptides. The results demonstrated that the chemical synthesis of bacilotetrin C with suitable improvisation plays an important role in the development of novel anticancer chemotherapeutics, which would allow future rational design of novel autophagy inducers on this template.
