Using NMR to identify binding regions for N and C-terminal Hsp90 inhibitors using Hsp90 domains.
Article in RSC medicinal chemistry, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
We present the first NMR study of the interaction between heat shock protein 90 (Hsp90) and amino (N)-terminal inhibitors 17-AAG, and AUY922, and carboxy (C)-terminal modulators SM253, and LB51. We show that the two ATP mimics, 17-AAG and AUY922, bind deeply within the ATP binding pocket of the N-terminal domain, consistent with the crystal structures. In contrast, SM253, a C-terminal Hsp90 modulator, binds to the linker region between the N and middle domains. We also show that C-terminal inhibitor LB51 binds to the C-terminus with a more significant spectroscopic change than previously reported using NMR binding studies of C-terminal inhibitors novobiocin and silybin. These data provide key insights into how the allosteric inhibitor SM253 controls the C-terminal co-chaperones and confirms the binding domain of LB51.
