Cu(II)-mediated tautomerization for the pyrazole-nitrile coupling reaction.

This study investigates the mechanism of prototropic tautomerization in metal-bound asymmetric pyrazole (R-PzH) ligands during Cu(II)-mediated PzH-MeCN coupling reactions. Intrinsic prototropic tautomerization of metal-bound ligands has not been previously documented. Various new bis-pyrazolylamidino Cu(II) complexes, [Cu(R-Pz(HNC(Me)))(ClO)], from the coupling reaction, and tetrakis pyrazole Cu(II) complexes, [Cu(R-PzH)(ClO)], with symmetric and asymmetric -monosubstituted R-PzH ligands were synthesized and characterized.

Theory-driven EEG indexes for tracking motor recovery and predicting the effects of hybridizing tDCS with mirror therapy in stroke patients.

Stroke remains a leading cause of adult disability, underscoring why research continues to focus on advancing new treatment methods and neurophysiological indexes. While these studies may be effective, many lack a clear theoretical framework. The current study first determined the optimal combination effects of mirror therapy (MT) with transcranial direct current stimulation (tDCS) on the premotor or primary motor cortex on its short-term and sustained clinical outcomes.

Targeting DNA junction sites by bis-intercalators induces topological changes with potent antitumor effects.

Targeting inter-duplex junctions in catenated DNA with bidirectional bis-intercalators is a potential strategy for enhancing anticancer effects. In this study, we used d(CGTATACG)2, which forms a tetraplex base-pair junction that resembles the DNA-DNA contact structure, as a model target for two alkyl-linked diaminoacridine bis-intercalators, DA4 and DA5. Cross-linking of the junction site by the bis-intercalators induced substantial structural changes in the DNA, transforming it from a B-form helical end-to-end junction to an over-wounded side-by-side inter-duplex conformation with A-DNA characteristics and curvature.
