The reaction could be controlled by judicious choice of the solvent. 3-Hydroxy-oxindoles and 3,3-bis(indol-3-yl)indolin-2-ones were obtained in aprotic (DCE) and protic solvent (MeOH), respectively; the reactions proceeded at 30掳C with a broad substrate scope in each case. Several ...

But how much is the outcome of an enzyme reaction controlled by the destabilization of unwanted transition states? Here, we revive and critically review the hypothesis that the active site of enzymes also features elements of ‘negative catalysis’. We provide examples that show that enzyme ...
Because this method relies on a weak interaction between the enzyme and the support, the biocatalyst can easily desorb during the reaction due to changes in the conditions of the reaction media (pH, ionic strength, temperature, pressure, etc.). However, the weak interactions generally do not ...

they are not always ideal catalysts for practical applications because they are generally unstable and they inactivate rapidly through several mechanisms. In order to enhance enzyme stability, many strategies have been pursued in recent years. The present article is an attempt to provide detailed inform...
(300 U/mg). They found that the efficiency of stain removal was marginally increased with the addition of mixed enzymes compared to single enzymes, probably due to a synergistic reaction between protease and amylase. For example, the stain removal from a polyester/cotton fabric soiled with blood...
There is no documented benefit to maintaining nil per os orders longer than 1 to 2 days, especially if vomiting is reasonably controlled. Water tolerance should be tested first, and if there is no vomiting, food can then be offered. Some patients may not be able to tolerate oral or ...
It was not until the spread of antibiotics that the trend of bacterial infections was effectively controlled. However, the overuse and misuse of antibiotics has led to the emergence of drug-resistant strains of bacteria, posing a great threat to public health and the environment [2]. It is ...
