Overexpression of Rubisco Activase Improves Photosynthesis and Plant Growth in Rice Under Fluctuating Light Under Future High CO2 Conditions

open access: yesPlant, Cell &Environment, Volume 49, Issue 9, Page 6653-6667, September 2026.
ABSTRACT Rubisco activase mediates the activation of Rubisco, the key photosynthetic CO2‐fixing enzyme, and plays a crucial role in regulating photosynthesis and plant growth. Rubisco activase restores catalytic competence to Rubisco active sites by promoting the release of inhibitors in an ATP‐dependent manner.

From o‐Phenylenediamine to Flavin Derivatives: A Potential Prebiotic Carbon Skeleton Expansion With Formaldehyde, Cyanide, and CO2

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.
A Strecker‐type reaction of aromatic ortho‐diamines with various aldehydes and cyanide assembles the bicyclic amidine core of flavin‐derived heterocycles under mild conditions. Subsequent oxidation, radical or photochemical cyanation, carboxylation with CO2, and CO2‐mediated cyclization build the three‐ring alloxazine scaffold. This sequence provides a

Actinomycin Derivatives: Structural Diversification and Biological Activities

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

Structural and Functional Insights Into (S)‐5′‐C‐Guanidinopropyl Uridine‐Modified Oligonucleotides With 2′‐O‐Methyl and 2′‐Fluoro Substitutions for RNAi Therapeutics

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Novel (S)‐5′‐guanidinopropyl uridine analogs bearing 2′‐O‐methyl or 2′‐fluoro substitutions enhance nuclease resistance and mismatch discrimination while preserving A‐form RNA structure and potent RNAi activity. These modifications provide a promising strategy for improving the stability, specificity, and therapeutic potential of siRNA‐based medicines.

Contribution of One‐Electron Oxidation of Purine and Pyrimidine Bases to the Photo‐ and Radiation‐Induced Damage to Cellular DNA

open access: yesChemPhysChem, Volume 27, Issue 15, 14 August 2026.
One‐electron oxidation of purine and pyrimidine bases of isolated and cellular DNA generates related reactive base radical cations that are converted into final decomposition products through deprotonation and hydration. In the case of guanine, the most susceptible nucleobase to one‐electron oxidants, 8‐hydroxy‐7,8‐dihydroguanyl radical, thus formed by
