Design, synthesis, and biological evaluation of prazosin-related derivatives as multipotent compounds.

ABSTRACT

To combine in the same molecule alpha(1)-adrenoreceptor blocking and antioxidant properties, compounds 2-5 were designed and synthesized. All compounds were effective alpha(1)-adrenoreceptor antagonists and were tested in both functional and binding assays. In addition, compounds 2 and 5 also displayed significant capacity to inhibit intracellular oxidative stress, whereas 3-5 exerted potent antiproliferative activity in lymph node carcinoma of prostate cells.
