    摘要： A family of hexadentate Fe(II) chelators having marked antiproliferative activity against tumor cells is disclosed. The cytotoxic metal chelators and complexes of the present invention are represented by the general formula below: wherein: X1, X3, and X5 are N, O or S, wherein the X1, X3, and X5 atoms are at the 1, 3, and 5 positions of a cyclohexyl group and are in a cis, cis disposition; B, B′, and B″ are aliphatic, branched aliphatic, or aryl groups, or any combination thereof, wherein the number of atoms between X and Y is about 2 to about 4; Y, Y′ and Y″ contain N, O, or S atoms that originate from either aliphatic, branched aliphatic, aryl, or heterocyclic groups, or any combination thereof, and/or Y, Y′ and Y″ are NH2 or NHR, OH, or SH, CO2H, P(O)(OH)2, RP(O)OH, ROP(O)OH groups or a combination thereof, and R is H, aliphatic, branched aliphatic, or aryl groups, or any combination thereof that may or may not be identical in Y, Y′ and Y″; s, s′, and s″ are 0 to about 2; and t, t′, and t″ are 0 to about 2. Application of the metal chelators of the present invention as chemotherapeutic agents is also disclosed.

    摘要： Disclosed are novel sulfenate esters and thiosulfinate esters that induce the expression of metabolic enzymes, particularly Phase II enzymes such as glutathione-s-transferase, DT-diaphorase and Ferritin H when administered to a subject. Also disclosed, such compounds are effective to displace a zinc ion from retroviral zinc finger nucleocapsid proteins effective to inhibit HIV replication. The present invention is further directed to novel methods of making these compounds, and any compounds produced by the process of making these novel compounds.
