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.

designed as inhibitors of the parasite specific enzyme trypanothionereductase (TR), and their biological activities were evaluated. Some of our compounds inhibited TR, showed selectivity for TR over human glutathione reductase, and inhibited parasite growth in vitro. We propose that the quinazoline framework is a privileged structure that can be purposely modified to design novel TR inhibitors. Furthermore
