Optimization of Brain Penetrant SARM1 Orthosteric Inhibitors and Discovery of Their Paradoxical Subinhibitory Activation.
Article in ACS medicinal chemistry letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
SARM1 (sterile alpha and Toll/interleukin-1 receptor motif-containing 1) has recently emerged as a promising therapeutic target for several neurodegenerative diseases. Herein, we detail our optimization of SARM1 orthosteric base exchange inhibitors. Early chemical matter was found to be substrates for either Pgp/MDR1 or breast cancer resistant protein (BCRP), resulting in compounds with poor overall brain exposure in rodents. Using structure-based drug design, we identified the crucial interactions for driving adduct formation and subsequently optimized the molecules to eliminate the MDR1 and BCRP efflux, yielding tool compounds with sufficient brain penetration to have a pharmacodynamic (PD) effect. Ultimately, we found these compounds activated SARM1 at low doses, leading to serious adverse events in vivo. These preclinical findings highlight the liability for these base exchange inhibitors for further progression.
