Chelators & Bifunctional Chelators

Chelators and bifunctional chelators bind metal ions through several donor atoms of one molecule. The coordinating groups hold the ion in a ring structure, which lowers its free concentration and changes its redox behavior and availability. Calcium-selective chelators such as BAPTA buffer intracellular calcium in cell biology and electrophysiology experiments. Iron chelators form the largest group here and include HBED, deferitazole, VK-28 and CN128 hydrochloride, used in studies of iron metabolism and oxidative stress. Penicillamine and succimer bind copper, lead and other heavy metals through thiol and amine donors. Bifunctional chelators add a reactive group for coupling to peptides or proteins, as in DTPA-tetra (t-Bu ester), a protected form of diethylenetriaminepentaacetic acid (DTPA).
