已知具有生理活性的α-皮考啉酸的硫酰替芳胺类化合物C_5H_4N·CS·NH·C_6H_4R常以S、N原子与Ni(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ)等过渡金属离子形成螯合物。为了探索具有抗
It is known that the physiologically active α-picolinic acid compounds S_5H_4N · CS · NH · C_6H_4R often undergo transitions of S, N atoms with Ni (II), Cu (II), Zn Metal ions form chelates. To explore with resistance
