title: Tubulin-polymerization inhibitors derived from thalidomide.
abstract: 2-(2,6-Diisopropylphenyl)-5-hydroxy-1H-isoindole-1,3-dione (5HPP-33), which was obtained during our previous structural development studies on thalidomide, was revealed to possess potent tubulin-polymerization-inhibiting activity, comparable to that of the known tubulin-polymerization inhibitors, rhizoxin and colchicine. A major metabolite of thalidomide, 5-hydroxythalidomide, which possesses a hydroxyl group at the position corresponding to that of 5HPP-33, also showed moderate inhibitory activity.
