Class C beta-lactamases from Pseudomonas aeruginosa and several species of the Enterobacteriaceae have been observed to undergo a rapid burst in hydrolysis of beta-lactam antibiotics before relaxation to a steady-state rate of hydrolysis. The amplitude of the burst corresponds to

Reactions using fluorous reagents and scavengers are compared side-by-side with their solid-supported counterparts. Fluorous triphenylphosphine is used in the bromination reaction of alcohols, fluorous thiol is used as an electrophile scavenger for alpha-bromoketones, fluorous isatoic anhydride is used as a

Isatoic anhydride reacts with nucleophile groups of proteins to yield o-aminobenzoyl protein conjugates. The fluorescence emitted by the chromophore decays in a multiexponential manner with average fluorescence lifetimes ranging from 9.9 to 10.7 ns. The steady emission anisotropy, measured upon

A simple and efficient protocol for one-pot three-component coupling of isatoic anhydride, amines, and aldehydes in water using magnetically recoverable Fe(3)O(4) nanoparticles is reported. This methodology results in the synthesis of a variety of 2,3-dihydroquinazolin-4(1H)-ones in high yields. The catalyst

Derivatives of isatoic anhydride were prepared and tested as inhibitors of serine proteases. A number of isatoic anhydrides with positively charged substituents irreversibly inactivated several trypsin-like enzymes and preferentially inactivated trypsin over chymotrypsin. Further selectivity was obtained by introduction of
