Binding Constants of Substituted Benzoic Acids with Bovine Serum Albumin

Pharmaceuticals, 2020
Experimental data on the affinity of various substances to albumin are essential for the development of empirical models to predict plasma binding of drug candidates. Binding of 24 substituted benzoic acid anions to bovine serum albumin was studied using

The Substituent Effect on the Radical Scavenging Activity of Apigenin

Molecules, 2018
Flavonoids widely found in natural foods are excellent free radical scavengers. The relationship between the substituent and antioxidative activity of flavonoids has not yet been completely elucidated. In this work, the antioxidative activity of apigenin

Synergistic effects between acidity and the crystalline phases of thermally activated layered Zn hydroxide nitrate on the methanolysis of acidic soybean oils

Heliyon, 2023
Layered hydroxyl salts (LHS) is a promising catalyst in the field of methanolysis (transesterification and esterification reactions) of oil feedstocks. The catalytic activity of the catalyst can be enhanced with heat treatment.

Borosulfates Hosting Se42+ Ions—Crystal Structures, Chemical Bonding, Optical Spectroscopy, and Magnetism

Angewandte Chemie, EarlyView.
Apart from (transition) metal (oxo)halides only few hosts stabilize chalcogenide cations in purely oxoanionic coordination environment. Herein, we report on five borosulfates containing the Se42+ ion and characterize the compounds using X‐ray diffraction, diffuse reflectance spectroscopy, density functional theory (DFT) calculations along with magnetic

Resonance Effect in Hammett Relationship. IV. Linear Free Energy Relationship based on the Normal Substituent Constants [PDF]

Bulletin of the Chemical Society of Japan, 1966
Abstract A set of normal substituent constants, σ0, was derived from the rates of alkaline hydrolysis of m- and p-substituted ethyl phenylacetates in 60% (v/v) aqeuous acetone at 25.0°C. The obtained values of σ0-constants were generally identical with Taft’s values within experimental uncertainty.
