Decreased DNA Damage and Improved p53 Specificity of RITA Analogs.
Article in Molecular cancer therapeutics, 2022. 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
Reactivation of p53 tumor-suppressor function by small molecules is an attractive strategy to defeat cancer. A potent p53-reactivating molecule RITA, which triggers p53-dependent apoptosis in human tumor cells in vitro and in vivo, exhibits p53-independent cytotoxicity due to modifications by detoxification enzyme Sulfotransferase 1A1 (SULT1A1), producing a reactive carbocation. Several synthetic modifications to RITA's heterocyclic scaffold lead to higher energy barriers for carbocation formation. In this study, we addressed the question whether RITA analogs NSC777196 and NSC782846 can induce p53-dependent apoptosis without SULT1A1-dependent DNA damage. We found that RITA analog NSC782846, but not NSC777196, induced p53-regulated genes, targeted oncogene addiction, and killed cancer cells upon p53 reactivation, but without induction of DNA damage and inhibition RNA pol II. Our results might demonstrate a method for designing more specific and potent RITA analogs to accelerate translation of p53-targeting compounds from laboratory bench to clinic.
