Synthesis and antiproliferative activity of benzocyclobutacarbazol derivatives. A new class of potential antitumor agents.

Several benzocyclobutacarbazol derivatives were synthesized and evaluated for their potential cytotoxic properties. A number of these compounds exhibited significant antiproliferative activity with concomitant interaction with the cell cycle and represent a new class of potential anticancer agents.

Novel indole-2-carboxamide and cycloalkeno[1,2-b]indole derivatives. Structure-activity relationships for high inhibition of human LDL peroxidation.

Series of indole-2-carboxamide and cycloalkeno[1,2-b]indole derivatives were synthesized and evaluated in order to determine the necessary structural requirements for a high inhibition of human LDL copper-induced peroxidation. Various modulations were systematically performed on the indole and cycloalkeno[1,2-b]indole nuclei as well as on the carboxamide moiety. The best compounds (3c, 3e, 7c, 7f, 7h, 7g, and 7o) are between 5 and 30 times more active than probucol itself.
