Abstract
Co-Administration of CuII chelates are reported to decrease life threatening Cisplatin [PtII(NH3)2(CL)2]-induced acute degenerative renal, gastrointestinal, thymic, and bone marrow states consistent with serious necrotizing and immunemediated inflammatory disease. Initially it was found that copper sulfate treatment completely prevented lethality as well as gastric and nephrotoxicity without compromising PtII(NH3)2(CL)2 antineoplastic activity, which led to suggestions that prior CuIItreatment be used clinically to prevent serious side effects of PtII(NH3)2(CL)2-treatment. In the course of these studies it was discovered that CuII-treatments alone inhibited neoplastic growth and increased survival of rat and mouse models of cancer. Subsequently it was discovered that a stable non-toxic and non-polar lipophilic chelate, CopperII 2(3,5-diisopropylsalicylate)4, caused redifferentiation of cultured neuroblastoma and mouse muscle-implanted mammary adenocarcinoma without neoplastic cell killing. Another stable non-toxic and non-polar lipophilic chelate, CopperII 2(3,5-ditertiarybutylsalicylate)4, was found to prevent Bax-initiated and caspases-3-activation mediated apoptosis. These remarkable observations are concluded to be due to enzyme-mimetic or modulating reactivities of CuII chelates and/or facilitation of CuII or I-dependent enzyme syntheses required to overcome inflammatory-neoplastic disease states. Further, approaches to treating neoplastic diseases by removal of Cu from tissues with ammonium tetrathiomolybdate in an anticopper approach to therapy are not well founded based upon existing scientific literature.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
