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

A series of combretastatin A-4 (CA-4) analogues have been prepared from (Z)-substituted diarylacrylonitriles (1a-1p) obtained in a two-step synthesis from appropriate arylaldehydes and acrylonitriles. The resulting 4,5-disubstituted 2H-1,2,3-triazoles were evaluated for their anti-cancer activities against a panel of 60 human cancer cell lines. The diarylacrylonitrile analogue 2l exhibited the most potent anti-cancer activity in the screening studies, with GI₅₀ values of <10 nM against almost all the cell lines in the human cancer cell panel and TGI values of <10 nM against cancer cell lines SF-539, MDA-MB-435, OVCAR-3 and A498. Furthermore, in silico docking studies of compounds 2l, 2e and 2h within the active site of tubulin were carried out in order to rationalize the mechanism of the anti-cancer properties of these compounds. From the in silico studies, compound 2e was predicted to have better affinity for the colchicine binding site on tubulin compared to compounds 2l and 2h. Analogue 2e was also evaluated for its anti-cancer activity by colony formation assay against 9LSF rat gliosarcoma cells and afforded an LD₅₀ of 7.5 nM. A cell cycle redistribution assay using analogue 2e was conducted to further understand the mechanism of action of these CA-4 analogues. From this study, analogues 2e and 2l were the most potent anti-cancer agents in this structural class, and were considered lead compounds for further development as anti-cancer drugs.
