SC75741, A Novel c-Abl Inhibitor, Promotes the Clearance of TDP25 Aggregates
Article in Frontiers in pharmacology, 2021. 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
Abnormal accumulation of TDP43-related mutant proteins in the cytoplasm causes amyotrophic lateral sclerosis (ALS). Herein, unbiased drug screening approaches showed that SC75741, a multi-target inhibitor, inhibited inflammation-induced aggregation by inhibiting NF-κB and also degraded already aggregated proteins by inhibiting c-Abl mediated autophagy-lysosomal pathway. We delineate the mechanism that SC75741 could markedly enhance TFEB nuclear translocation by an mTORC1-independent TFEB regulatory pathway. In addition, SC75741 enhanced the interaction between p62 with TDP25 and LC3C, thus promoting TDP25 degradation. Taken together, these findings show that SC75741 has beneficial neuroprotective effects in ALS. Our study elucidates that dual-targeted inhibition of c-Abl and NF-κB may be a potential treatment for TDP43 proteinopathies and ALS.
