A degradation pathway of 2-chloro-4-aminophenol (2C4AP) was studied in an Arthrobacter sp. SPG that utilized 2C4AP as its sole source of carbon and energy. The 2C4AP degradation was initiated by a 2C4AP-deaminase that catalyzed the conversion of 2C4AP into chlorohydroquinone (CHQ) with removal of ammonium ion. In the next step, a CHQ-dehalogenase dehalogenated CHQ to hydroquinone (HQ) that clea...

In this study, new benzoxazole-linked pyrrolidinone heterocyclic compounds were synthesized by an eco-efficient strategy using substituted benzylamines and 2-aminophenol under ultrasonic irradiation in the presence of a newly designed metal-free deep eutectic solvent (DES). This DES was prepared mixture urea glycine-derived ionic liquid. X-ray diffraction infrared spectroscopy employed to inves...

measured by CO-reduced difference spectroscopy (Omura & Sato, 1964) was retained on this column. The concentrated CM-cellulose eluate was dialyzed to pH7.4, and then applied to a DEAE-Sephadex or QAE [diethyl-(2-hydroxypropyl)aminoethyl]-Sephadex column. Peak I eluted from the DEAE-Sephadex exhibited UTP-glucuronyltransferase activity. UDP-glucuronyltransferase activity towards various substrat...

Rigid dendrimers with flexible ferrocenyltriazolyl termini serve as excellent supports for remarkably efficient and recyclable Pd Au nanocatalysts biphasic reduction of 4-nitrophenol to 4-aminophenol at 20 °C.

Hydrolysis of paracetamol in acidic media was studied using electrochemical technique in different reaction temperatures. Based on the fact that both paracetamol (PAR) and its hydrolyzed product, p-aminophenol (PAP) are both electroactive and their voltammetric peaks do not overlap, differential pulse voltammetry was used for the determination of the remained PAR concentration in the reaction v...
