Pyrroloquinoline quinone (PQQ), an essential nutrient, antioxidant, redox modulator and nerve growth factor found in a class of enzymes called quinoproteins, was labeled with 99mTc by using stannous fluoride (SnF2) method. Radiolabeling qua...
Why is monoalkylation versus bis-alkylation of the Ni(II) complex of the Schiff base of (S)- N-(2-benzoylphenyl)-1-benzylpyrrolidine-2-carboxamide and glycine so selective? MP2 modelling and topological QTAIM analysis of chiral metallocomplex synthons of α-amino acids used for the preparation of radiopharmaceuticals for positron emission tomography [0.03%]
为什么(S)-N-(2-苯甲酰基苯基)-1-苯甲基吡咯烷-2-甲酰胺和甘氨酸的希夫碱的Ni(II)配合物单烷基化与双烷基化的选择性如此之高?用于制备正电子发射断层扫描放射性药物的手性金属合成子α-氨基酸配合物的MP2建模及拓扑QTAIM分析
