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.

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
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.

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.

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
