In vitro glucuronidation of methyl gallate and pentagalloyl glucopyranose by liver microsomes.
Article in Drug metabolism and pharmacokinetics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Methyl gallate (MG) and pentagalloyl glucopyranose (PGG) are bioactive phenolic compounds that possess various pharmacological activities. However, the knowledge of hepatic metabolism of MG and PGG is limited. The purpose of this study was to investigate the in vitro glucuronidation of MG and PGG using liver microsomes from human (HLMs) and rats (Sprague-Dawley, SDRLMs; Wistar, WRLMs; and Gunn, GRLMs), and recombinant human uridine 5'-diphospho-glucuronosyltransferases (UGT) 1A1 and 1A9. The results demonstrated that liver microsomes catalyzed two mono-glucuronided MG (M1 and M2) formations but that UGT1A1 and 1A9 catalyzed only M1 formation. For PGG, a mono-glucuronided metabolite was mediated by liver microsomes or UGT1A9. However, a PGG glucuronide was absent in the UGT1A1 system. Additionally, all metabolites showed susceptibility to β-glucuronidases. Furthermore, the glucuronidation activities of PGG were lower than those of MG. The kinetic parameters of MG glucuronidation demonstrated that the SDRLMs and GRLMs were more similar to the HLMs than the WRLMs for the formations of M1 and M2, respectively and that the SDRLMs and HLMs preferentially contributed to M1, whereas the WRLMs and GRLMs showed the favored formation of M2. In conclusion, MG and PGG were subjectively glucuronided by liver microsomes to demonstrate species- and strain-dependent metabolism.
