Characterization of Five Natural Anthraquinone Compounds as Potent Inhibitors against CYP1B1: Implications for Cancer Treatment.
Article in Current drug metabolism, 2024. 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
backgroundHuman cytochrome P450 1B1 (CYP1B1) is an extrahepatic enzyme that is overexpressed in many tumors and is associated with tumor development and acquired resistance. Few studies have reported that anthraquinone compounds have inhibitory activity against the CYP1B1 enzyme. Cassiae semen (Leguminosae) is a well-known traditional Chinese medicine containing more than 70 compounds. The crude extracts and pure compounds of
objectiveAloe-emodin, chrysophanol, obtusifolin, aurantio-obtusin, and rhein have a wide range of pharmacological activities and have been found to have good anti-tumor and antioxidant effects. However, the underlying mechanisms of these pharmacological activities remain poorly understood. This study aimed to investigate the inhibitory effects of five natural anthraquinones on the activity of CYP1B1 and to analyze the structure- activity relationship of these compounds. MATERIALS AND
methodsIn this study, 7-ethoxyresorufin O-deethylation (EROD) was used as the fluorescent substrate of CYP1B1 to investigate the inhibition effect, and molecular docking was performed to further determine the structural-activity relationship of the compound molecules.
resultsWe found that aloe-emodin and chrysophanol had strong inhibitory effects on CYP1B1 with IC
conclusionThe present study provided a comprehensive analysis of the inhibitory effects of five natural anthraquinones, namely aloe-emodin, chrysophanol, obtusifolin, aurantio-obtusin and rhein, on CYP1B1 activity, and elucidated the structure-activity relationship. Molecular docking simulations further revealed the specific amino acid residues within the active site of CYP1B1, where these compounds exerted their actions. These findings offer novel insights into investigating the potential antitumor properties of natural anthraquinones.
