The present invention relates to metal thiourea complexes comprising N-substituted thiourea ligands and sulfur-coordinated metal ions, and methods for using the metal thiourea complexes for delivering otherwise unstable or impermeable metal ions to mammalian cells, for inhibiting cancer cell growth and inflammation, and for inhibiting the activities of associated drug targets under in vitro and in vivo conditions. The metal complexes of N-substituted thiourea are defined by the following formula (Ia or Ib) wherein R
1
can be H, alkyl, alkenyl, alkynyl, aryl or heterocyclic groups; R
2
can be H, alkyl, alkenyl, alkynyl or aryl groups; n=1 to 4; X
−
is a pharmaceutically acceptable anion (chloride, bromide, iodide, hexafluorophosphate, or triflate) and M is a coinage metal (Au, Ag, or Cu).
