Novel 2-pyridinecarboxaldehyde thiosemicarbazones Ga(III) complexes with a high antiproliferative activity by promoting apoptosis and inhibiting cell cycle

Two types of 2-pyridinecarboxaldehyde thiosemicarbazones Ga(III) complexes, which are 2:1 and 1:1 ligand/Ga(III) complexes, were synthesized and determined by X-ray single crystal diffraction. The antiproliferative activity of these Ga(III) complexes have been examined to illuminate the structure-activity relationships essential to form Ga(III) complexes with remarkable anticancer activity. In addition, Ga(III) complexes where the metal/ligand...
