Existence of an internal carbonic anhydrase was demonstrated in the cyanobacterium Synechocystis PCC 6714. The enzyme, present at a low specific activity, was inducible by limitation in inorganic carbon and inhibited both in vivo and in vitro by acetazolamide. The internal inorganic carbon pool as determined by mass spectrometry, was similarly modulated by the actual inorganic carbon growth reg...

Capsaicin, the component responsible for the pungency of chili peppers, shows beneficial effects in many diseases, although the underlying mechanisms remain unclear. In the present study, the potential targets of capsaicin were predicted using PharmMapper and confirmed via chemical-protein interactome (CPI) and molecular docking. Carbonic anhydrase 2 was identified as the main disease-related t...

Mgz+. The enzyme assays were accompanied by measurements of the phosphorylation with [pJZP]ATP. After incubation of intact rabbit erythrocytes with adrenaline (Fig. l), maximal activation of carbonic anhydrase occurred within 5min. In chicken erythrocytes, one of the two isolated isoenzymes could be activated and phosphorylated (for conditions, see the legend of Fig. 2). The carbonic anhydrase ...

Ocular oxygen concentration by the process of counter current multiplication in rainbow trout (Salmo gairdneri) was rapidly suppressed after intraperitoneal injections of the carbonic anhydrase inhibitor CL-11,366. The rapidity with which this drug acted suggested a short circuiting of the choroidal rete mirabile. A comparison was made between the time after injection of inhibitor at which oxyg...

Two new small-molecule enzyme mimics of carbonic anhydrase were prepared and characterized. These complexes contain the salen-like ligand bis(hydroxyphenyl)phenanthroline. This ligand is similar to the salen-type ligands previously incorporated into carbonic anhydrase mimics but contains no hydrolyzable imine groups and therefore serves as a promising ligand scaffold for the synthesis of a more...

Binary Logistic Regression (BLR) has been developed as non-linear models to establish quantitative structure- activity relationships (QSAR) between structural descriptors and biochemical activity of carbonic anhydrase inhibitors. Using a training set consisted of 21 compounds with known ki values, the model was trained and tested to solve two-class problems as active or inactive on the basi...

Cryptophane Biosensors for Targeting Human Carbonic Anhydrase Cryptophanes represent an exciting class of xenon-encapsulating molecules that can be exploited as probes for nuclear magnetic resonance imaging. A series of carbonic anhydrase-targeting, xenon-binding cryptophane biosensors were designed and synthesized. Isothermal titration calorimery and surface plasmon resonance measurements conf...
