Description
Technical field
What the application related to is a kind of ligand chemical compound, this preparation process of mixture that is used for diagnostic imaging, and this image diagnosis chemical compound and be used for the midbody compound that it prepares this ligand chemical compound accordingly.
Background technology
Carbohydrate metabolism is active to be an important metabolic characteristics of tumor cell.One of metabolic main feature of malignant cell is that its glucose uptake increases and the anerobic glycolysis effect strengthens.Be called as " century molecule " glucalogue 18 fluorodeoxyglucose (
18F-FDG) can be absorbed by tumor cell, in the tumor tissues
18The F-FDG level distribution is apparently higher than tumor tissues normal structure and benign lesion on every side, be used to clinically to the Differential Diagnosis of innocent and malignant tumour focus, pernicious focus by stages with classification, differentiate the recurrence of tumor focus and variation due to the treatment back, the curative effect of various anticancer therapies monitored and the prognosis judgement of the state of an illness etc. that clinical meaning is great.But
18F-FDG PET (positron computer layer video picture) needs to produce with cyclotron, the cost height, and the half-life short (only 110 minutes), used in addition nuclear medicine PET imager costs an arm and a leg, and these have all limited its penetration and promotion in basic medical unit is clinical and have used.
In addition,
99mTc has ideal nuclear physics performance, long half time (6.02 hours), and the gamma-rays of emission 40KeV,
99mThe Tc generator obtains easily, thereby is optimal γ video picture radionuclide.With
99mTc labelled glucose analog will have the important clinical meaning, and be used widely.Yang DJ was at Radiology 2003 in 2003; Among the 226:465-473, once reported synthetic ethylenedicysteine (EC)-D-glucose (DG), and used
99mThe Tc labelling; Right
99mThe distribution research prompting of Tc-ECDG: tumor/brain and tumor/muscle ratio are higher than
18F-FDG,
99mThe Tc-ECDG video picture can clear demonstration malignant tumor focus.Therefore
99mTc-ECDG with
18F-FDG all can be absorbed by malignant tumor and as malignant tumor functional molecular developer.But because
99mThe distribution of Tc-ECDG shows that its tumor and tumor/lung ratio less than 1.0, are lower than
18F-FDG, thereby
99mTc-ECDG also is not ideal
99mTc labelling DG developer, with
18F-FDG has big gap.Therefore, it is low to study a kind of tumor uptake height, tumor/background height, bio distribution and video picture ideal and cost
99mThe DG derivant of Tc labelling is necessary.
