Inhibition of Butyrylcholinesterase with Fluorobenzylcymserine, An Experimental Alzheimer's Drug Candidate: Validation of Enzoinformatics Results by Classical and Innovative Enzyme Kinetic Analyses.
Article in CNS & neurological disorders drug targets, 2017. 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
backgroundSelective butyrylcholinesterase (BuChE)-inhibition, increases acetylcholine (ACh) levels. In rodents, this inhibition is known to boost cognition. Also, this occurs without the typical unwanted adverse effects of acetylcholinesterase-inhibitors or AChE-Is. The novel compound, fluorobenzylcymserine (FBC), is derived from our effort to design a selective BuChE-inhibitor. Also, we wanted to check whether butyrylcholinesterase-inhibitors (BuChE-Is) possessed an edge over AChE-Is in Alzheimer's disease (AD) in terms of efficacy and/or tolerance.
methodFBC was synthesized as reported earlier while enzymatic activity of BuChE was calculated by Ellman-technique. Molecular docking was performed using Autodock4.2. We applied classical as well as innovative analyses of enzyme-kinetics for exploring "FBC:human BuChE-interaction". The mode of inhibition and kinetic parameters were also determined.
resultsDocking results displayed two strong interacting sites for FBC. One of these binding sites was previously identified as a deep narrow groove having polar aromatic residues while a second site was identified during this study which displayed better interaction and was lined with aliphatic and sulphur containing residues. At low concentrations of BuChE, the IC50 was found to be very low i.e. 4.79 and 6.10 nM for 12 and 36 µg, respectively, whereas it increased exponentially by increasing the units of BuChE.
conclusionThese analyses indicate that FBC is an interesting AD drug candidate that could provide a potent and partial mixed type of inhibition of human BuChE.
