翻译如下，希望有所帮助：
the anti-tumor mechanism of hydrazones compounds is mainly based on  chelating metal ion which has something to do with the  rapid proliferation of tumor tissues. Another possible mechanism is to inhibit the  enzyme activity(Nucleotide reductase , acetylation enzyme , acyl transferase),also,it is likely to form  toxic metal complex(producing toxic active free radicals by redox) to insert into the DNA of tumor tissues，

已经给翻译了，为什么不回应呢？
