Abstract
Novel cinchona alkaloid compounds have been synthesized and discovered to have potent cytotoxic activity against cancer cells both in vitro and in vivo. Cinchona alkaloids, including trimeric cinchona alkaloids as well as their polymers can be used as catalysts of complex chemical reactions in organic chemistry, for example for the enantioselective desymmetrization of cyclic anhydrides, asymmetric synthesis of amino acids (Ayyanar Siva, Eagambaram Murugan.
