8-Nitrotryptanthrin inhibits colorectal cancer progression via TGF-β/SMAD and PI3K/AKT/mTOR pathways.
Article in Frontiers in pharmacology, 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
Objective: To investigate the anticancer effects and underlying mechanisms of 8-nitrotryptanthrin (8-Nitrotryp) against colorectal cancer (CRC). Methods: The effects of 8-Nitrotryp on proliferation, colony formation, and migration were evaluated in HCT116 and SW480 cells, with comparisons to its parent compound tryptanthrin (Tryp). Mitochondrial membrane potential (MMP) was assessed using JC-1 staining, and early apoptosis was analyzed by flow cytometry. Proteomic analysis and Western blotting were employed to examine the modulation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mechanistic target of the rapamycin (mTOR) pathway and transforming growth factor-β (TGF-β)/Sma- and Mad-related proteins (SMAD) signaling pathways, as well as epithelial-mesenchymal transition (EMT). Results: 8-Nitrotryp significantly inhibited proliferation of HCT116 (IC Conclusion: 8-Nitrotryp inhibits CRC progression by modulating the TGF-β/SMAD and PI3K/AKT/mTOR pathways, highlighting its potential as a multi-target therapeutic agent for CRC and warranting its further investigation. Novelty and Impact: CRC is a global health challenge with limited treatments for advanced stages. This study provides the first evidence of 8-Nitrotryp's antitumor efficacy in CRC, demonstrating its dual inhibitory activity on the TGF-β/SMAD and PI3K/AKT/mTOR pathways. Compared to Tryp, 8-Nitrotryp exhibits markedly enhanced potency, with lower IC
