AbstractThis paper proposes a new type of molecular device that is able to act as an inverse proton sponge to slowly decrease the pH inside a reaction vessel. This makes the automatic monitoring of the concentration of pH‐sensitive systems possible. The device is a composite formed of an alkyl chloride, which kinetically produces acidity, and a buffer ...

The effect-kinetics of the new benzodiazepine midazolam was evaluated in six subjects after single oral (7.5 and 15 mg) and intravenous (0.075 mg/kg) doses and infusion programs. The drug is bound to plasma proteins by 94%, and less than 0.5% is excreted unchanged in urine.

Piperacillin was administered to normal, healthy volunteers by an intravenous infusion over 30 min at dosage regimens of 12 gm daily (4 gm every 8 hr) and 24 gm daily (6 gm every 6 hr) for 5 consecutive days. Mean peak serum level after 12 gm daily was 244 ± 24 (SE) βg/ml and after 24 gm daily, 353 ± 7 βg/ml.

Annual Review of Biochemistry, 2022
Biochemistry and molecular biology rely on the recognition of structural complementarity between molecules. Molecular interactions must be both quickly reversible, i.e., tenuous, and specific. How the cell reconciles these conflicting demands is the subject of this article.

Flavoproteins are ubiquitous proteins involved in diverse biological processes ranging from redox catalysis and light emission to DNA repair (1). Based on their function, flavoproteins can be divided into several subclasses including electron transferases, photolyases, synthases, dehydrogenases, disulfide reductases, oxidases, and monooxygenases.

Biophysics of Structure and Mechanism, 1980
Three mechanisms have been suggested to describe the inhibition of acetylcholinesterase (EC. 3.1.1.7) by an excess of acetylcholine. (i) Substrate inhibition occurs through the reaction of acetylcholine with acetylated enzyme. The deacetylation of this ternary complex is supposed to be completely inhibited.

Captopril, an angiotensin-converting enzyme inhibitor with antihypertensive properties, was given by mouth and intravenously in 10-mg doses to five healthy subjects. After intravenous dosing, semilogarithmic plots of captopril blood levels : time showed a triexponential decay. Data were analyzed using an open three-compartment model. The average volume
