<p>The present invention relates to ligand-targeted molecules and ligand drug conjugates (LDCs) comprising a ligand connected to a functional group, which is connected to a linker, wich in turn is bonded to a drug. The LDCs of the present invention also comprise platinum coordination complex wherein the platinum is connected to the linker through monocarboxylato and O->Pt coordinate bonds. The present invention also relates to methods for preparing these ligand drug conjugates. The present invention further relates to methods for the treatment of tumours using the ligand drug conjugates of the present invention.</p>
