Multifaceted In Silico and DFT-Based Analysis of 2‑Aminosuccinic Acid on Ferroptosis-Related Targets.

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
Metabolic reprogramming and redox imbalances in cancer cells play a significant role in tumor growth and development of treatment resistance. In recent years, ferroptosis, a type of programmed cell death characterized by iron-dependent lipid peroxidation, has emerged as a promising target for cancer therapy. Amino acid transport, glutathione (GSH) homeostasis, and antioxidant defense mechanisms are critically important in the regulation of ferroptosis. In this study, the interactions of 2-aminosuccinic acid, involved in amino acid metabolism, with key molecular targets associated with ferroptosis were investigated using an in silico molecular docking approach. Docking analyses revealed that the compound showed significant binding affinities with SLC1A1 (EAAT3), SLC7A11 (xCT), and the GPX4/GSH system. The observed binding energy of -5.0 kcal/mol with SLC7A11 is noteworthy in terms of modulating intracellular cysteine/glutathione balance and regulating ferroptosis sensitivity. These findings suggest that 2-aminosuccinic acid may be a potential molecule capable of influencing ferroptosis in cancer cells via amino acid transport and redox regulation. In addition, the structural, electronic, spectroscopic, and thermodynamic properties of 2-aminosuccinic acid were extensively investigated using density functional theory (DFT) with the 6-311G basis set. The molecule's geometry was optimized to a stable conformation, and the calculated bond lengths followed values reported in the literature. The HOMO-LUMO energy gap (Δ
