Abstract

Previous studies established some Ti compounds as having marked activity against tumors of the gastrointestinal tract and lack of side effects common to widely used cytostatic agents. We describe pertinent structural features of known antitumor Ti agents and other potentially active compounds. Particularly noteworthy features are thatTi-Obonds are short andTi-O-Tibond angles are large, demonstrating that in these compounds the O binding has high s-character approaching sp hybridization.
