WebJan 13, 2024 · Ligands are small molecules that transmit signals in between or within cells. Ligands exert their effects by binding to cellular proteins called receptors. The ligand is like the baton, and the ... WebGiven the wide substrate scope of the CuAAC “click” reaction used to construct the ligands, it should be possible to prepare a library of helicates that would enable convenient structure-activity studies. Herein we report the synthesis and biological properties [60,61,62,63,64,65,66,67,68,69] of a small family of Fe(II) “click” helicates.
The interaction of ligands with their binding sites can be characterized in terms of a binding affinity. In general, high-affinity ligand binding results from greater attractive forces between the ligand and its receptor while low-affinity ligand binding involves less attractive force. In general, high-affinity binding results in a higher occupancy of the receptor by its ligand than is the case for low-affinity … WebPublisher Summary. This chapter describes the potential ligands that could be involved in binding metals in metalloproteins. These can divided into naturally occurring amino acids in the protein itself; amino acids that have been chemically modified in order to bind specific metal ions, such as Ca 2+; low-molecular weight inorganic ligands, such as carbonate, …
WebMetallic nanodot arrays are created on glass coverslips and are then used as anchors for the immobilization of biological ligands via thiol linking chemistry. The nanodot size is controlled by both lithography and metallization. The reagent concentration in self-assembly can be adjusted to ensure single-molecule occupancy for a given dot size.

WebApr 14, 1998 · The biological ligands now known bind to PPARγ with relatively low affinity (K d = 2–50 μM), compared with the affinity (typically K d < 1 nM) for most bona fide ligands for nuclear receptors. Whether the known PPARγ ligands represent endogenous activators for this receptor is not clear.
