The square-planar heteroleptic Pt(II) coordination compound [Pt(bpy)(dicnq)](NO3)(2) (1) and the quaternized dicnq ligand, namely 12,13-dicyano-5,6-dihydrodipyrazino[2,3-f:1',2',3',4'-lmn] [1,10] phenanthroline-4,7-diium dibromide (2) (Fig. 1) were synthesized and fully characterized by means of FTIR, NMR, MALDI-TOF MS and the purity was confirmed by CHN analyses. The DNA binding profiles of 1 and 2 were identified in an identical condition. The biological activities of these compounds were investigated by the assays of transcription and replication inhibition, cytotoxic and antimicrobial activity.
