Several cycline dependent kinase 2 (CDK2) inhibitors with different chemical structures have been introduced. The hinge region of CDK2 (residues 81–84) contains a set of hydrogen bond donor and acceptor sites some of which must be satisfied for potent inhibitor binding. The benzimidazolone skeleton may provide such interactions. Accordingly, 3-sulfonamide substituted benzamido-benzimidazolones ...

α-amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2zncl2 as a bio lewis acidic ionic liquid. mild lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.

Chloride channels were previously purified from bovine kidney cortex membranes using a drug affinity column. Reconstitution of the purified proteins into artificial liposomes and planar bilayers yielded chloride channels. A 64 x 10(3) M(r) protein, p64, identified as a component of this chloride channel, was used to generate antibodies which depleted solubilized kidney membranes of all chloride...

1. Total body, intracellular, and extracellular electrolyte and acid-base changes were studied following sodium nitrate-induced potassium and chloride depletion and subsequent selective chloride repletion. 2. It was found that potassium and chloride depletion was associated with markedly decreased extracellular Na, K, CI and water content. Intracellular Na increased, intracellular K decreased a...

When iodides are administered in ordinary doses excretion takes place rapidly. Heavy doses can usually be administered before toxic symptoms develop. The same is true to an even greater extent of bromides. The bromide ion appears to be capable of replacing the chloride ion to a Considerable degree in the body fluid of mammals without the production of distinct toxic symptoms. Thus Frey (1910--1...

Antimicrobial chemicals are widely applied to clean and disinfect food-contacting surfaces. However, the cellular response of bacteria to various disinfectants is unclear. In this study, the physiological and genome-wide transcriptional responses of Bacillus cereus ATCC 14579 exposed to four different disinfectants (benzalkonium chloride, sodium hypochlorite, hydrogen peroxide, and peracetic ac...
