Copper is an essential trace element with vital roles in many metalloenzymes; it is also prominent among nonplatinum anticancer metallodrugs. Copper-based complexes are endogenously biocompatible, tenfold more potent than cisplatin, exhibit fewer adverse effects, and have a wide therapeutic window. In cancer biology, copper acts as an antitumor agent by inhibiting cancer via multiple pathways. Herein, we present an overview of advances in copper complexes as 'lead' antitumor drug candidates, and in understanding their biochemical and pharmacological pathways over the past 5 years. This review will help to develop more efficacious therapeutics to improve clinical outcomes for cancer treatments.

The Schiff base metal complexes containing the transition metal ions Co(II), Ni(II) and Cu(II) were synthesized using their nitrate and acetate salts. An octahedral environment encircling metal complexes has been demonstrated by the findings of multiple spectroscopic approaches that were employed to demonstrate the structure of the metal complexes. The Coats-Redfern method of thermal analysis was employed to carry out the kinetic and thermodynamic calculations.

Catalytic transformation of carbene species constitutes a fundamental part in organic synthesis, and the research in this direction has been dominated by transition metals while organic catalysts are difficult to mimic such transition-metal-like reactivity. It would significantly advance carbene chemistry if organic catalysts enable achieving classical metal-carbene approaches otherwise unrealizable reactions. Herein, we report that chalcogen bonding catalysis can solve reactivity problem to achieve an elusive Buchner ring expansion of aryl ketones appending a cyclopropene moiety as carbene precursor.

The synthesis, isolation, and full characterization of a series of NHC-copper perfluoro-alkoxide complexes are reported. Their exceptional stability resides with the steric hindrance of the nonafluoro--butyl alkoxide moiety, which exhibits a strong electron withdrawing effect. These new Cu(I) complexes are synthons that can permit the activation of acidic N-H and S-H bonds.

A cation exchange (CE) reaction offers a remarkable opportunity to create versatile metal sulfide nanocrystals (NCs) with arbitrary complexity in composition, structure, and functionality. The concept of regioselectivity has been discovered and developed to build the target heterostructures through CE reactions, yet a general principle of regioselectivity remains unclear. In this work, we establish connections between experimental results and theoretical insights to elucidate the determinants of regioselectivity using designed aliovalent CE reactions on a two-dimensional template.

Many industries use copper metal ions (Cu ions), and their salts are utilized as supplemental materials in both agriculture and medicine. Identifying and monitoring these Cu ions in biological and environmental specimens is crucial due to their association with several health issues. In this investigation, we have designed a simple quinoline-based receptor (E)-3-(((2,4-di-tert-butyl-5-hydroxyphenyl)imino)methyl)-6-methoxyquinolin-2(1H)-one (QAP) containing imine functional groups to inspect its capability to identify metal ions in a semi-aqueous medium.
