Abstract

Pt(C^N)(phe) (1, C^N = 2-(2′-thienyl)pyridine, phe = phenylalanine) shows a high binding affinity (ca. 10⁶ dm³ mol⁻¹) and selectivity towards human serum albumin (HSA) and such binding is accompanied by an enhancement of photoluminescence at 562 nm; both the protein binding affinity and cytotoxicities of [Pt(C^N)(phe) (1), Pt(C^N)(trp) (2, trp = tryptophan) and Pt(C^N)(gly) (3, gly = glycine)] are affected by the amino acid ligand with 1 having an IC₅₀ of up to 1 μM against a number of carcinoma cell lines.
