Comparative biological evaluation between 99mTc(CO)3 and 99mTc-Sn (II) complexes of novel quinoline derivative: a promising infection radiotracer

A novel quinoline derivative, 2,2′-[(5-chloro-8-hydroxyquinoline-7-yl) methylazanediyl] diacetic acid (CHQMADA) was labeled with 99m Tc using SnCl 2 ·2H 2 O as a reducing agent to give a complex with a labeling yield 94 %. Also [ 99m Tc(H 2 O) 3 (CO) 3 ] + was prepared by heating at 100 °C for 30 mi...
