Cancer is one of the leading causes human death among all major diseases. Metal-based complexes are considered as most promising vital part in existing arsenal cytotoxic candidates used cancer therapy and diagnostics. The efforts many scientific groups resulted development numerous metal-based compounds featuring different biologically active organic ligands order to modulate their bioactivity. Along with main representatives potential therapeutic agents, such Pt(II)/Pt(IV), Pd(II), Ru(II)/Ru(III), Ag(I), Au(I)/Au(III), Ti(IV), V(IV) Ga(III), other transition metal lanthanide possessing antiproliferative activity widely discussed literature. However, drugs remain outside scope this review. purpose current study review group metal- metalloid-based against common cell types, carcinomas (lung, liver, breast, kidney, gastric, colorectal, bladder, ovarian, cervical, prostate, etc.); sarcomas; blastomas; lymphomas; multiple myeloma; melanoma. Overcoming long disregard organometallic metals metalloids from groups, a growing number emerging anticancer agents remarkably prove field offers an extensive variety new options for design innovative unexplored chemopharmaceutics.
