Our focus this month is on the dithiocarbamate (DTC) complexes whose synthesis is described in the paper by Malin Backlund Walker, Kimberly Edwards, and Patrick J. Farmer (1). Molecules added to the collection include disulfiram, the diethyldithiocarbamate anion (deDTC), and copper and zinc complexes of diethyldithiocarbamate (Figure 1).Dithiocarbamate complexes are found for both transition metals and main group elements, and have broad applications in medicine and other fields, as mentioned in ref 1. One might envision introducing the primary literature to a group of students, in either majors or nonmajors courses, with assignments that involve finding how such complexes are currently being used, and the nature of ongoing research involving these species. Additionally, Volume 53 of Progress in Inorganic Chemistry is devoted entirely to dithiocarbamate complexes across the periodic table (2).Dithiocarbamate complexes are also interesting from a structural viewpoint. They exhibit a wide range of coordination geometries and modes of bonding. Diethyldithiocarbamate is found as a unidentate ligand, a bridging ligand, and as a bidentate in both symmetrical and unsymmetrical environments (3). These complexes can serve as the basis for a number of exercises in computational chemistry. Included in the collection are the copper(II) and zinc(II) complexes synthesized in ref 1. The structures that are given arise from DFT (B3LYP/631-G(d)) calculations on gas phase molecules. The copper complex has a slightly distorted square planar arrangement about the copper, and the zinc complex, as expected, shows a distorted tetrahedral coordination structure. Students could be asked to predict, and then calculate, structures with different metals and/or different oxidation states, to assess the effect of these on the overall structure. They might find that the calculations are more tractable using model compounds, and included here is a copper complex with dithiocarbonate that might serve as a starting point for calculation. Many other questions could be

The principles governing metal-ligand complex stability and specificity depend on the properties of both the metal and the chelating agent. The exploration of coordination chemistry offers the real prospects of providing new understanding of intractable diseases and of devising novel therapeutics and diagnosis agents. Refinement in the approach to chelator design has come with a more subtle understanding of binding kinetics, catalytic mechanisms and donor interactions. Ligands that effectively bind metal ions and also include specific features to enhance targeting, reporting, and overall efficacy are driving innovation in areas of disease, diagnosis and therapy. In this contribution the topics of bioinorganic medicinal chemistry, chelating agents in the treatment of metallic ion overload in the body, and expanding the notion of chelating agent in medicine are successively dealt with, paying then attention to platinum, gold, iron, copper and aluminium ion metal complexes having medicinal interest. A tabular summary containing selected applications of ligands and complexes of therapeutic interest is also shown to including the most relevant and current bibliography. A number of papers concerning miscellaneous topics based on selected key words are also tabulated. Metal chelation principles offer wide new opportunities in the drug design field in addition to the classical answer of metal sequestration or elimination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
