NCIt definition : The hydrochloride salt form of a metal chelating agent with potential anti-angiogenic
activity. Trientine chelates excess copper (Cu) ions in the body; the excess copper
is subsequently removed from the body through the kidneys. As Cu is an essential cofactor
for cuproenzymes, such as superoxide dismutase 1 (SOD1), depletion of copper may inhibit
the activation of signal transduction pathways required for cellular proliferation
and angiogenesis. In addition, trientine may inhibit copper-induced secretion of interleukin-8
(IL-8).;
