Computer aided study on cyclic tetrapeptide based ligands as potential inhibitors of Proplasmepsin IV.
Article in Scientific reports, 2025. 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
The belief that we could always stay ahead of the pathogens was forced upon scientists in the whole world by antimicrobial resistance. According to several reports, there are medications that are yet to be made public in the pipeline and there are little motivations to design novel antimicrobials to combat the worldwide drug resistance issues. Presently, the desire to design and develop efficient novel anti-bacterial agents is very high by researchers; thus, this study focuses on identifying the interactions between the studied ligands and Proplasmepsin IV, as well as examining the relationship between the calculated descriptors and binding affinities. This work shows successful prediction of the reacting and inhibiting efficiency of ten (10) cyclic tetra-peptides using insilico method. The optimization of the studied compound revealed the proficiency of methyl (3S,9S,12S)-12-(1,3-dioxoisoindolin-2-yl)-9-(2-(methylthio)ethyl)-5,8,11-trioxo-4,7,10-triaza-1(1,3)-benzenacyclotridecaphane-3-carboxylate (F5) and 2-((3S,9S,12S)-12-(1,3-dioxoisoindolin-2-yl)-3-(methoxycarbonyl)-5,8,11-trioxo-4,7,10-triaza-1(1,3)-benzenacyclotridecaphane-9-yl)acetic acid (F7) to react more than the remaining molecules in term of HOMO and LUMO energies. In comparison, compound F9 demonstrated a higher inhibitory activity than the reference drug, Chloroquine, based on binding affinity. Molecular dynamics simulations over a 100 ns period further explored the binding affinity between F9 and the reference drug. The results showed that the reference drug (- 21.91 ± 1.16 kcal/mol) had a slightly stronger binding affinity than the F9_complex (- 13.85 ± 0.72 kcal/mol). Additionally, pharmacokinetic studies for F9 were compared with those of the reference compound and presented accordingly.
