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

introductionThe von Hippel-Lindau (VHL) E3 ubiquitin ligase has seen extensive research due to its involvement in the ubiquitin proteasome system and role as a tumor suppressor within the hypoxia signaling pathway. VHL has become an attractive target for proteolysis targeting chimeras (PROTACs), bifunctional molecules that can induce degradation of neo-substrate proteins. The development of VHL inhibitors and PROTACs has seen rapid development since disclosure of the first non-peptidic VHL ligand (2012). AREAS COVERED: Due to the demand for more diverse and sophisticated VHL ligands that can be applied to PROTACs, the number of patents disclosed has risen significantly in the past 5 years. Herein, the wide range of VHL modifications that have been patented since 2019 is covered. Specifically, any new or unique chemical modification to established VHL ligands or PROTACs will be discussed. EXPERT OPINION: The VHL chemical space continues to expand within the patent literature. There are exciting new modifications that can enhance the physiochemical properties of VHL PROTACs and other alterations can improve the affinity of the VHL ligand itself. Further optimization of the VHL chemical space will no doubt lead to the development of more VHL-based therapies and clinical candidates.
