The invention provides particular mono- and dinucleoside 5'-phosphorothioate analogues, more particularly mono- or di- adenosine or uridine 5'-di- or tri- phosphorothioate analogues in which at least one of the bridging oxygen atoms of the phosphorothioate is replaced by a group such as -CH2-, and at least one of the non- bridging atoms or negatively-charged atoms of the phosphorothioate is either a sulfur atom or a sulfur ion; and pharmaceutical compositions thereof. These compounds are useful for treatment of neurodegenerative diseases or disorders such as Alzheimer's disease.
Metal chelators are potential therapeutic agents for treating diseases such as Wilson’s and Alzheimer’s where the pathology involves an excess of metal-ions (Cu(II) and Zn(II)/Cu(II)/Fe(II/III), respectively). In addition to the high affinity of the metal-ion to the chelators, metal selectivity of the chelators is essential to achieve the therapeutic goal, that is, the successful removal of excess

A 13-membered methylenediphosphonotetrathioate–crown ether hybrid is a water-soluble, air-stable, high-affinity Zn(ii)-chelator, exhibiting selectivity to Zn(ii)vs.Mg(ii), Na(i), and Li(i).
