The phrase "a selectivity over" is not correct in standard written English.
It is typically used incorrectly; the correct preposition would be "in" or "for" depending on the context.
Example: "The study demonstrated a selectivity in the response to different stimuli."
Alternatives: "a preference for" or "a focus on".
In an 80% aqueous solution, KB2 responded to Hg2+ in a ratiometric manner with a good selectivity over a range of metal cations.
One gold silver catalyst exhibits a constant selectivity over a wide potential range.
Then, the performance of the best AC was selected to evaluate and compare with the relative affinity for developing a selectivity order over a range of concentration.
Kinase assays were conducted and showed that compound 11 inhibited CDK5 with an inhibitory concentration of 160 nM with a moderate selectivity over GSK3 compared to the reference C which exhibited a slightly lower activity on CDK5 (1.5 μM).
The most active catalyst Au/Cu Al2O3 shows a conversion of 50% at 483 K and a N2 selectivity over 90%.
The graphitic carbon membrane, obtained by heat treatment at 600 °C, exhibited excellent gas separation properties, including a remarkable CO2 permeability of 5040 Barrer with a high selectivity over CH4 of 38.
A pseudo-ring formed by an intramolecular hydrogen bond constrained the conformation of 3-chloro-4-methoxybenzylamino and 3,4,5-trimethoxybenzoyl substituents and led to the discovery of T-6932 (19a) with a potent PDE5 inhibitory activity (IC50 = 0.13 nM) and a high selectivity over PDE6 (IC50 ratio: PDE6/PDE5 = 2400).
This compound exhibited a binding affinity value of 0.094 nM toward human 5-HT4R and a high selectivity over other serotonin receptor subtypes (5-HTR).
6,7-Dimethoxycoumarin derivatives carrying a protonatable benzylamino group, linked to position 3 by suitable linkers, exhibited fairly good AChE inhibitory activity and a high selectivity over BChE.
