This study examined if complexation with metals increased the antiproliferative activities of chelators of the pyridoxal isonicotinoyl hydrazone (PIH) class. Addition of iron(III) to some PIH analogs markedly depressed their activities, whereas it had little effect on others. The gallium(III) complex of PIH, but not its copper(II) complex, was more efficient than the apochelator at inhibiting [3H]thymidine incorporation.
本研究考察了与金属络合是否会增强吡啶醛异烟酰腙(PIH)类螯合剂的抗增殖活性。向一些PIH类似物中添加铁(III)会显著降低其活性,而对其他类似物影响不大。PIH的镓(III)络合物而非其铜(II)络合物在抑制[3H]胸腺嘧啶核苷掺入方面比游离螯合剂更有效。
