Ribosomal translation of fluorinated non-canonical amino acids for biologically active fluorinated macrocyclic peptides.

Fluorination has emerged as a promising strategy in medicinal chemistry to improve the pharmacological profiles of drug candidates. Similarly, incorporating fluorinated non-canonical amino acids into macrocyclic peptides expands chemical diversity and enhances their pharmacological properties, from improved metabolic stability to enhanced cell permeability and target interactions. However, only a limited number of fluorinated non-canonical amino acids, which are canonical amino acid analogs, have been incorporated into macrocyclic peptides by ribosomes for construction and target-based screening of fluorinated macrocyclic peptides.

Hydrochar did not reduce rice paddy NH volatilization compared to pyrochar in a soil column experiment.

Pyrochar (PC) is always with high pH value, and improper application might increase rice paddy ammonia volatilization (PAV), which is the main nitrogen loss through air during rice production. Differently, hydrochar (HC) takes the advantages of high productive rate and always with lower pH value compared with PC. However, effect pattern and mechanism of HC on PAV are still unclear.

Degradation of norfloxacin by copper-doped BiWO-induced sulfate radical-based visible light-Fenton reaction.

In this work, a series of Cu(ii)-doped BiWO nanomaterials with good photo-response properties were facile synthesized and used to obtain efficient peroxymonosulfate (PMS) activation activity for norfloxacin (NOF) removal under visible LED light irradiation. It was found that Cu-BiWO presents superior catalytic performance for NOF degradation in comparison with pristine BiWO, attributed to the partial substitution of Bi by Cu ions. Moreover, the effects of experimental conditions were carefully investigated, including PMS concentration, catalyst dosage and initial pH, and the experimental data fitted well with the pseudo-first-order model.
