Molecular docking analysis of nitisinone with homogentisate 1,2 dioxygenase.
Article in Bioinformation, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Alkaptonuria is an inherited disease that is caused by homogenticate accumulation. Deficiency or mutation in Homogentisate 1,2 dioxygenase gene (chromosome 3q21-q23) leads to production of incorrectly folded or truncated enzyme. Several studies indicated that competitive inhibitors of Homogentisate 1,2 dioxygenase like Nitisinone could be used for Alkaptonuria treatment. Therefore, it is of interest to design better inhibitors of the enzyme. We used subset 3_p.0.5 from Zinc database as the virtual screening library by PyRx software relaying on Lamarckian genetics algorithm. Top 10 hits with more efficient binding affinity were analyzed and hit No#5 and No# 7 was selected for further design. In Lig No#5, we decreased the hydrophobicity by adding oxygen in the hydrophobic tail of the molecule at positions C5 and C10. The new compound of (2Z, 5Z, 8Z)-6,9-Dihydroxy-2-(2-hydroxy-5-oxo-1,3-cyclohexadien-1-yl)-2,5,8-decatrienoic acid satisfied Lipinski rules as well as PhysChem and FafDrugs filters. Moreover, the modified version of Lig No# 7 with the IUPAC name of [2-(Carboxymethyl)-3,5-dihydroxyphenyl] acetic acid satisfies the Lipisnki, FafDrugs and Physchem.
