Aromatic amines could be produced from organic wastes via catalytic pyrolysis with ammonia that served not only as a carrier gas but also as a reactant. Aromatic amines of 14.2 C% with selectivity of 57.6% were obtained from phenol-formaldehyde resins via pyrolysis over commercial HZSM-5-3 zeolite (Si/Al ratio of 80) catalyst at 650 °C. Significant synergetic effects have been observed when lignin was added, which improved aromatic amines yield by 32.2% to 11.8 C% at the mixing weight ratio of lignin to PF resins of 1:1. HZSM-5-3 was slightly deactivated after 3 cycles with acid sites loss. Catalytic co-pyrolysis of plastics and biomass wastes is a fast and effective method to produce aromatic amines.

The direct discharge of cationic surfactants into environmental matrices has exponentially increased due to their wide application in many products. These compounds and their degraded products disrupt microbial dynamics, hinder plant survival, and affect human health. Therefore, there is an urgent need to develop electroanalytical assessment techniques for their identification, determination, and monitoring.

Amide compounds are widely present in drug molecules and natural products, which can be synthesized by acid-amine condensation. It is urgent to design new photocatalysts for achieving both nitroaromatic reduction and C-H oxidation to obtain raw materials, carboxylic acids, and aromatic amines. Herein, a novel isopolymolybdate-incorporated photoactive metal-organic framework, -TPT, was constructed by combining the oxidation catalyst [MoO], Ni(II) cation, and photosensitive ligand 2,4,6-tri(4-pyridyl)-1,3,5-triazine (TPT).

The metabolic conversion of aromatic amines to N-acetylated forms in skin and keratinocytes depends on N-acetyltransferase-1 (NAT1). Common hair color ingredient such as para-phenylenediamine (PPD) causes allergic contact dermatitis. We explored how different electronic substituents on PPD aided NAT1 enzyme biotransform oxidative arylamine (AA) compounds G1-G13 by N-acetylation, NAT-1 activity assays, metabolism, and in vitro clearance investigations in human keratinocytes, while identifying NAT-1 protein levels by Western blot and qRT-PCR.

Pyrrolnitrin, a potent antifungal compound originally discovered in Pseudomonas strains, is biosynthesized through a secondary metabolic pathway involving four key enzymes. Central to this process is PrnB, a heme enzyme that catalyzes the complex transformation of 7-Cl-L-tryptophan. Despite its structural similarity to indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3-dioxygenase (TDO) and its classification within the histidine-ligated heme-dependent aromatic oxygenase (HDAO) superfamily, PrnB has remained relatively unexplored due to challenges in reconstituting its in vitro activity.
