Three unsymmetrically substituted polyamine analogues demonstrate significant and selective antitumor effects. |
The flexible polyamine spermine displays a high presence in the minor groove but does not form long-lived and structurally defined complexes. |
The reaction between the aldehyde and the organic amine or polyamine is usually conducted in the presence of an inert solvent. |
Greater problems arise from the hardener component of the resins, typically polyamine or anhydrides, which can displace ligands from TL materials based on metal complexes. |
This unique endemic cruciferous species from the subantarctic zone is subjected to strong environmental constraints and shows high polyamine contents. |
During reflow of the solder joints of the electronic module by heating, the modified passivation reacts with the polyamine at the amine functionality. |
