Schiff base ligands play important role in the synthesis of Schiff base complexes, since they have ability of forming stable complexes with metal ions (Arquero et al., 1985).
During the past two decades, considerable attention has been paid to the chemistry of the metal complexes with nitrogen and oxygen donor atoms ligands [1-3].
Repligen Corporation announced an agreement with Navigo Proteins for the advancement of exclusive novel affinity ligands used in monoclonal antibody and non-mAb downstream purification processes.
Polymer-metal complexes are an important class of polymers formed by coordination of polymeric ligands with transition metal ions [1].
categorised metal anticancer compounds based on their mode of action, which could be divided into five different classes: [9] (1) the metal has a functional role, (2) the metal has a structural role, (3) the metal is a carrier for main ligands that are delivered in vivo, (4) the metal compound behaves as a catalyst in vivo, and (5) the metal compound is photoactive.
G-protein coupled receptors (GPCRs) play an important role that involves detecting molecules or ligands from the outside of a cell and activating internal signal transduction pathways and cellular responses.
Until recently, this kinetic analysis has rarely been used because of the complexity of kinetic models that describe the possibilities of simultaneous binding and isomerization steps for two ligands. In order to analyze the kinetic behavior of this complex assay system, a kinetic model for a rather general ligand--receptor interaction scheme (Scheme 2) was compiled, taking into consideration different modes of ligand binding and isomerization steps and the simulated influence of ligands A and B on the kinetics of the reporter ligand binding.
The thermodynamic effect of cooperativity may be due to changes in the macromolecule's conformation or redistribution of the electron density at the site due to the influence through oligomers bonds or by the MI between bound ligands via space [17].
In this context, TLR7 ligands are especially promising since they induce robust Th1-biased immune responses [2].
