An Aromatic Intermediate in the Bacterial Oxidation of Quinic Acid [PDF]
Strains of Pseudomonas and Achromobacter spp. isolated from soil, utilized quinic acid as a sole source of carbon. Protocatechuic acid was produced as an intermediate in this oxidation. Protocatechuic acid was also produced in the course of oxidation of p-hydroxybenzoic acid by these organisms.

ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.
