The methods of step by step synthesis of N-Acetyl-1, 6-diaminohexane (NADAH) onto the diol silica have developed. Hexamethylene bisacetamide (HMBA) and metabolite NADAH are inducers of leukemia cells differentiation. The results show that some calf thymus DNA has stronger hydrophobic interaction since some DNA were eluted out while the ion intensity was decreased very low until below that of the normal physiological conditions, but no notable ion-exchange. These suggested that HMBA and NADAH should exist the hydrophobic interaction with some DNA in the process of their inducing tumor cells differentiation.
