New aminoadamantane derivatives with antiproliferative activity

1-Benzyl-2-aminoadamantanes 2a–c, conformationally constrained aminoadamantanes 3a, b and 4 and diaminoadamantanes derivatives 5a–c, 6a–c were synthesized and tested as antiproliferative agents. The in vitro biological evaluation showed a significant difference in activity between 1-phenyl and 1-benzyl derivatives.
