INFLUENCE OF σ DONATION AND π ACCEPTANCE PROPERTIES OF SPECTATOR LIGANDS ON SUBSTITUTION REACTIONS IN BIFUNCTIONAL MONONUCLEAR PLATINUM(II) COMPLEXES: EXPLORING REACTIVITY PATTERN OF ANTITUMOR COMPOUNDS
and Parnajyoti Karmakar
Chemistry and Chemical Technology, 2025
Kinetics and mechanism of ligand substitution reactions on square planar platinum (II) complexes have been explored continuously over the last few decades. This was after the fortuitous discovery of the antiproliferative activity of cisplatin by Barnett Rosenberg in 1965, which attracted much attention from various other investigators to design new Pt(II) drugs with better activity and fewer side effects. Cisplatin's clinical success as a chemotherapeutic drug has promoted the discovery of succeeding generations with efficacy and less toxicity. The focal aim of these investigations was based on tailoring the steric and electronic properties of spectator ligands to influence the solubility, pKa, and molecular association or reactivity of the platinum complexes to promote the potential of the antitumor drugs. This mini-review provides accounts on: i) the mechanisms of substitution at the Pt(II) complexes in general and the key factors that control the reactivity, and ii) the trends in experimentally measured rate data and how they are controlled by varying the σ-donation and π-acceptance abilities of the spectator ligand. Furthermore, the reactivity patterns of platinum complexes are analyzed, highlighting how σ-donating and π-accepting ligands influence their biological activities. The insights gained from kinetic and mechanistic studies are essential for the development of more effective and less toxic platinum-based anticancer drugs.

A brief overview of mechanistic studies on the reactions of cis-[Pt(dap)(H2O)2]2+ (1) and cis-[Pt(pipen)(H2O)2]2+ (2) (where dap and pipen are 1,3-diaminopropane and 2-aminomethylpiperidine respectively) with 2-thiouracil (LH), a nitrogen and sulfur-donor bio molecule, is presented. All the substitution reactions have been monitored at 327(for 1) and 326 (for 2) nm respectively where the differences in abosorbances between the reactants and products are maximum. At pH 4.0, the kinetics shows two consecutive processes, i.e., they show a non linear dependence on the concentration of ligand: first process is [ligand] dependent but the second step is [ligand] independent. The activation parameters and the thermodynamic parameters were also calculated, which supports the spontaneous formation of an outer sphere association complex. The product of this reaction has been characterized with the help of Job's method, IR and ESI-MS spectroscopic analysis. The purpose of this work is to improve the understanding of the mechanism of action of Pt(II) complexes as potential anti-tumour drugs in the human body.
Mechanistic aspects of ligand substitution on the cis-diaqua-chloro-tris(dimethyl sulfoxide)ruthenium(II) complex by some sulfur-containing bioactive ligands in aqueous medium

Progress in Reaction Kinetics and Mechanism, 2018
The synthesis and interactions of the cis-diaqua-chloro-tris(dimethyl sulfoxide)ruthenium(II) complex with selected sulfur-containing ligands such as 2-thiouracil, glutathione and L-cysteine have been studied by UV-Vis spectrophotometry in aqueous medium at pH 4.5. From experimental data it is clear that all three reactions proceed via two steps: the first one being a rate-limiting ligand-dependent replacement of one water molecule, followed by a ligand-independent ring closure step with the expulsion of the second water molecule. The substituted products have been characterised by Job's method, FTIR spectroscopy and electrospray ionisation mass spectrometry. Activation parameters (Δ H≠ and Δ S≠) and thermodynamic parameters (Δ H0 and Δ S0, from the temperature dependence of the outer-sphere association equilibrium constant) are presented. Consistent with the experimental findings, an associative interchange mechanism is proposed.

The substitution of the chelating oxalate group by a group of nucleophiles, viz. thiourea (L1), 2‐thiouracil (L2), diethyldithiocarbamate (L3), dl‐penicillamine (L4), and thiosemicarbazide (L5) was studied under pseudo–first‐order conditions as a function of concentration and temperature using UV–vis spectrophotometry and stopped‐flow technique. π‐Accepting effects are often used to account for the unusual high lability of Pt(bipy) complexes. The complexes [Pt(dach)(oxalate)] (1) (dach = cis‐1,2‐diaminocyclohexane) and [Pt(bipy)(oxalate)] (2) (bipy = 2,2'‐bipyridine) and substituted products were isolated and characterized by FTIR and ESI‐MS spectroscopic analysis. The negative entropies of activation support a strong contribution from bond making in the transition state of the substitution processes.
