Original cytotoxic bisindolealkaloids with a 1,2,3,4-tetrahydroquinoline bridge were synthesized by reductive amination with various anilines. The most cytotoxic compounds display a high and dose-dependent cell cycle effect with accumulation in the G1 phase. Influence of substitution of the starting aniline on the reaction and on cytotoxicity of produced dimers was pointed out.

The serine protease urokinase (uPa) has been implicated in the progression of both breast and prostate cancer. Utilizing structure based design, the synthesis of a series of substituted 4-[2-amino- 1,3-thiazolyl]-thiophene-2-carboxamidine is described. Further optimization of this series by substitution of the terminal amine yielded urokinase inhibitors with excellent activities. (C) 2001 Elsevier Science Ltd. All rights reserved.
