1 · What the graph read from it

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.

2 · The registry

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

contextFLT3 is a critical therapeutic target for acute myeloid leukemia (AML), and its inhibition remains a key strategy in AML management. In this study, we optimized the known compound CHEMBL4444839 to design a novel analogue, CHEMBL4444839-Analogue, showing improved pharmacological and structural characteristics. Pharmacokinetic profiling evaluation revealed that the analogue had enhanced drug-likeness, metabolic stability, and intestinal permeability, along with reduced predicted toxicity. Molecular docking revealed that CHEMBL4444839-Analogue exhibited a binding energy of -10.4 kcal/mol versus -8.7 kcal/mol for the parent compound, forming additional hydrogen bonds and hydrophobic contacts with GLU661, CYS694, LEU818, and PHE830 in the ATP binding pocket. Molecular dynamics simulation over 100 ns demonstrated lower average RMSD (1.78 Å vs 2.34 Å) and reduced RMSF fluctuations at the activation loop and DFG-out region, indicating enhanced conformational stability. Free energy calculations confirmed higher thermodynamic stability of the analogue versus CHEMBL4444839. The analogue also restricted domain motion and improved residue correlation, indicating better stabilization of FLT3 in its inactive conformation. Incorporation of a fluorocyclobutane moiety significantly contributed to enhanced rigidity and optimized interaction geometry, collectively establishing CHEMBL4444839-Analogue as a more promising and selective FLT3 inhibitor for AML therapy.

methodsDocking of CHEMBL4444839 and its designed analogue was performed to analyze binding interactions and guide structural modifications. Pharmacokinetic and toxicity parameters were predicted using SwissADME, ADMETlab 2.0, and ProTox-II. Molecular dynamics simulations were executed with GROMACS 2023 using the CHARMM36 force field to assess conformational stability, followed by MM-PBSA and dynamic cross-correlation analyses. The integrated computational results demonstrated that CHEMBL4444839-Analogue achieved stronger binding affinity, reduced flexibility, and superior stability compared to the parent molecule, validating its potential as an optimized FLT3 inhibitor candidate for further biochemical and therapeutic evaluation.
