Abstract:
The influence of a series of acyclic and cyclic aminophosphonates on the physicochemical properties of model (planar lipid membranes-BLM) and biological (erythrocytes-RBC) membranes was studied. The results obtained were compared with the results of physiological tests performed on the aquatic plant Spirodela oligorrhiza. It was found that the inhibition of plant growth by the compounds studied correlated, although not very highly, with the observed changes in the properties of membranes used. It was also found that both the biological activity of aminophosphonates and their efficiency at modifying the physicochemical parameters of membranes depended on their structural features.

Acid Halides to Amides: Aminolysis
In the first step of the aminolysis mechanism, the amine attacks the carbonyl carbon of the acyl chloride to form a tetrahedral intermediate. In the second step, the carbonyl group is re-formed with the elimination of a chloride...
Basicity of Aliphatic Amines
To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates higher...

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
