Guanidine Derivatives: Conformation, Capability for Chelation, Study as Reversible Inhibitors of Cholinesterases of Different Origin

Study of spatial structure of biologically active guanidine derivatives by the method of molecular mechanics has shown that in an anticoccidial drug, 1,3-bis ( p-chlorobenzylidenamino)guanidine (Cl-BAG) the most preferable are convolute conformations, in which the chlorine atoms that are distant in the valent chain are approached to each other at a distance of 3.7 Å. This indicates predisposition of the optimal conformations to form chelate …
