Platinum(II)-based antitumor drugs are widely used in clinics but limited by severe side effects and resistance. Multi-target Platinum(IV) complexes are emerging as ideal alternatives. Heme oxygenase-1 (HO-1) works as a rate-limiting step in heme degradation and is overexpressed in malignant tumors.

Low-lying and small tropical coral reef islands around the world are extremely vulnerable to the effects of global environmental change caused by the combination of anthropogenic climate change and escalating extreme hydrodynamic events. Erosion and inundation are anticipated to physically destabilize the tropical coral reef islands, rendering them uninhabitable within the next century. Therefore, it is crucial to assess the repercussions of these hazardous events on the delicate reef island ecosystem in order to conserve and ensure sustainable management.

Although two examples of σ-bonded -bent [RSbSbR] (R = bulky organo- or Ga-groups) that formally contain the Sb radical trianion moiety are known in p-block chemistry, d- or f-element Sb radical trianion complexes, with or without R-substituents, have remained elusive. Here, we report that reduction of a 77:23 mix of [{Th(Tren)}(μ-η:η-Sb)] (, Tren = {N(CHCHNSiPr)}):[{Th(Tren)}(μ-SbH)] () with 1.5 equiv of KC in the presence of 1.

[CuL(tmen)] is a sequence of four ternary mononuclear Schiff base copper(II) complexes that are derived from L-valine, suitable 5'-substituted-2'-hydroxyacetophenones (where the substituents are -Cl for L, -Me for L, -OMe for L, and -H for L), and tmen (where tmen-N,N,N',N' tetramethyl ethylenediamine). Without isolating the Schiff base ligand or producing any other intermediate products, all of the complexes were synthesised. These compounds were identified using elemental analysis, molar conductance, UV-Vis, FTIR, EPR, VSM-RT, and CD spectra.

Relaxation-induced dipolar modulation enhancement (RIDME) is a pulse EPR experiment originally designed to determine distances between spin labels. However, RIDME has several features that make it an efficient tool in a number of "nonconventional" applications, away from the original purpose of this pulse experiment. RIDME appears to be an interesting experiment to probe longitudinal electron spin dynamics, e.
