Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.Access to pyrazoles arylated at C4 and C5 positions remains challenging due to their similar reactivity under Pd‐catalyzed C–H activation conditions. Herein, we report on the synthesis of 4‐aryl‐5‐heteroarylpyrazoles involving Suzuki‐coupling, followed by Pd‐catalyzed C–H heteroarylation.

Mechanisms of base selection by the E.coli mispaired uracil glycosylase [PDF]
, 2008 The repair of the multitude of single-base lesions formed daily in the cells of all living organisms is accomplished primarily by the base-excision repair (BER) pathway that initiates repair through a series of lesion-selective glycosylases.

Fluidization of collisionless plasma turbulence
, 2018 In a collisionless, magnetized plasma, particles may stream freely along magnetic-field lines, leading to phase "mixing" of their distribution function and consequently to smoothing out of any "compressive" fluctuations (of density, pressure, etc ...

Archiv der Pharmazie, Volume 359, Issue 4, April 2026.Biomimetic supramolecular hosts in water affect outcomes and behavior of E/Z‐isomerizations. A deeper understanding of such effects can pave the way to understanding photochemical processes in more complex biological environments. The review displays examples of supramolecular hosts affecting the outcomes of E/Z‐isomerizations and subsequently ...

Synthesis, IR and NMR spectral correlations in some symmetrical diimines
Bulletin of the Chemical Society of Ethiopia, 2014 A series of diimines have been synthesized by coupling of diamine with substituted benzaldehydes. The purities of these diimines were checked by their analytical and spectroscopic data. The spectral frequencies νCN (cm-1), NMR chemical shifts (δ, ppm) of
