Evaluating the multitargeted potency of Pixuvri against cell cycle regulation proteins in cervical cancer.

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
Cervical cancer, primarily caused by persistent infection with high-risk human papillomavirus strains, leads to abnormal cell growth in the cervix. Globally, it accounts for over 600,000 new cases and 340,000 deaths annually, with the highest burden in low- and middle-income countries due to limited screening and vaccination. Early detection is challenging as initial stages are asymptomatic, while advanced cases are challenging to treat. Current options, including surgery, radiotherapy, and chemotherapy, face issues like toxicity, limited efficacy, recurrence, and drug resistance caused by tumor heterogeneity and adaptive mechanisms. Multitargeted drug design offers a solution by modulating multiple cancer pathways, enhancing efficacy, minimizing resistance, and reducing side effects. In this study, we screened Selleckchem approved library against cervical cancer proteins that regulate the cell cycle, particularly during mitosis and cell division (PDBIDs: 2VFX, 2WVI, 3KND, 4N14) using HTVS, SP, and XP docking followed by MMGBSA post-processing. Pixuvri (Pixantrone Maleate) emerged as the top candidate with docking scores of -5.234 to -9.218 kcal/mol and MMGBSA scores of -39.22 to -53.87 kcal/mol. Pixuvri is approved for non-Hodgkin lymphoma and exhibits minimal cardiotoxicity compared to anthracyclines. Interaction fingerprints highlighted key residues (4GLN, 4GLU, 3TRP), while pharmacokinetics, DFT computations, and WaterMap hydration site analysis supported its potential. Molecular dynamics (100 ns, NVT ensemble at 300K) validated stability by deviation and fluctuation studies and found many interactions to stabilize the complex, with binding free energy computations confirming its affinity. While the results support Pixuvri's repurposing for cervical cancer, experimental validation is essential for clinical application.
