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

The metabolic stability of compounds is often assessed at an early stage in drug discovery programs by profiling with hepatic microsomes. Exclusion of the reduced form of nicotinamide adenine dinucleotide phosphate (NADPH) in these assays provides insight into non-cytochrome P450 (CYP)-mediated metabolism. This report uses a matched molecular pair (MMP) application to assess which chemical substituents are commonly susceptible to non-NADPH-mediated metabolism by microsomes. The analysis found the overall prevalence of metabolism in the absence of NADPH to be low, with esters, amides, aldehydes, and oxetanes being among the most commonly susceptible functional groups. Given that non-CYP enzymes, such as esterases, may be expressed extrahepatically and lead to lower confidence in predicted pharmacokinetic profiles, an awareness of the functional groups that commonly undergo non-NADPH-mediated metabolism-as well as options for their replacement based on experimental MMP data-may help researchers derisk metabolic stability issues at an earlier stage in drug discovery.
