Synthetic, novel dimeric cinchona alkaloid compounds having potent cytotoxic activity against human cancer cells. The compounds are effective agents for inhibiting cellular proliferation, for example, in cancer cells. The compounds cause apoptotic cell death in and cause inhibition of clonogenic growth of human breast cancer, prostate cancer, leukemia, lymphoma cells at nanomolar concentrations. The chemical structure of the compound includes dimeric cinchona alkaloid and derivatives containing various groups attached in their structure. The compounds also possess hydroxy group functionality in the structure to enable the preparation of pharmaceutically applicable salts to enhance their solubility for ease of systemic administration in animals and in humans, for example, in cancer patients.

Synthetic dimeric cinchona alkaloids against cancer

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.

Methods for increasing the elimination half-life of key metabolites such as d4T by administering an aryl phosphate derivative of d4T having an electron withdrawing substituent on the aryl group and an amino acid substituent on the phosphate group are described. A preferred aryl phosphate derivative of d4T is HI-113 (d4T-5&prime;-&lsqb;p-bromophenyl methoxyalaninyl phosphate&rsqb;). The administration of HI-113 results in more prolonged systemic exposure to the key metabolites, Ala-d4T-MP and d4T, than administration of an equimolar dose of either metabolite. Each metabolite has a significantly longer elimination half life when formed in vivo from the administration of HI-113 than when the metabolite is administered directly.
