Title:
胆汁酸抱合体、それらの金属錯体との誘導体、及び関連する使用方法
Document Type and Number:
Japanese Patent JPH10501528
Kind Code:
A
Abstract:
Novel paramagnetic metal ion chelates and their use as contrast agents in the diagnostic technique known as "magnetic resonance imaging" (M.R.I.) of the gastrointestinal tract and particularly of the liver, are described. The novel compounds result from the conjugation of a bile acid with a chelating agent and are capable of chelating the ions of bivalent and trivalent metals. The compounds have formula A-L-B in which A is the residue of a bile acid and derivatives of a bile acid, B is the residue of a chelating agent of a bivalent or trivalent metal ion having an atomic number of 20 to 31, 39, 42, 43, 44, 49, 57 to 83, L is a ligand between A and B.
