Expanding the chemical diversity of CK2 inhibitors

None of the already described CK2 inhibitors did fulfill the requirements for successful clinical settings. In order to find innovative CK2 inhibitors based on new scaffolds, we have performed a high-throughput screening of diverse chemical libraries. We report here the identification and characterization of several classes of new inhibitors. Whereas some share characteristics of previously known CK2 inhibitors, others are chemically unrelated and may represent new opportunities for the development of better CK2 inhibitors. By combining structure-activity relationships with a docking procedure, we were able to determine the binding mode of these inhibitors. Interestingly, beside the identification of several nanomolar ATP-competitive inhibitors, one class of chemical inhibitors displays a non-ATP competitive mode of inhibition, a feature that suggests that CK2 possess distinct druggable binding sites. For the most promising inhibitors, selectivity profiling was performed. We also provide evidence that some chemical compounds are inhibiting CK2 in living cells. Finally, the collected data allowed us to draw the rules about the chemical requirements for CK2 inhibition both in vitro and in a cellular context.

New aerobic oxidation of benzylic compounds: efficient catalysis by N-hydroxy-3,4,5,6-tetraphenylphthalimide (NHTPPI)/CuCl under mild conditions and low catalyst loadingElectronic supplementary information (ESI) available: experimental details. See http://www.rsc.org/suppdata/cc/b4/b403004d/

Efficient aerobic oxidation of benzylic compounds using NHTPPI, a new NHPI analogue, as a key catalyst combined with CuCl, have been achieved under mild conditions and using as little as 1 mol% catalyst.

Efficient and Highly Selective Oxidation of Primary Alcohols to Aldehydes by N-Chlorosuccinimide Mediated by Oxoammonium Salts

2,2,6,6-Tetramethyl-1-piperidinyloxy catalyzes efficient oxidation of primary alcohols to aldehydes by N-chlorosuccinimide, in a biphasic dichloromethane-aqueous pH 8.6 buffer system in the presence of tetrabutylammonium chloride. Aliphatic, benzylic, and allylic alcohols are readily oxidized with no overoxidation to carboxylic acids. Secondary alcohols are oxidized to ketones with a much lower efficiency. Very high chemoselectivities are observed when primary alcohols are oxidized in the presence of secondary ones. Primary-secondary diols are selectively transformed into hydroxy aldehydes, with, in some cases, no detectable formation of the isomeric keto alcohols.

Use of stresscath for diagnosing stress incontinence

The modified fluid bridge (flow) test (MFBT) is a simple procedure for detecting bladder neck incompetency using a fluid-filled catheter. The Stresscath (Hollister) female diagnostic catheter is an improved version of the MFBT. We evaluated the ability of the Stresscath to detect bladder neck incompetence in the first 66 female patients referred for urodynamics. The absence or presence of stress incontinence was based on the results from history and physical examinations. The results from the Stresscath correlated with the history showed that the Stresscath had a sensitivity of 0.73 and a specificity of 0.88 in determining stress incontinence due to bladder neck incompetency. The results from the Stresscath correlated with the physical examination (Marshall test) showed that the Stresscath had a sensitivity of 0.86 and a specificity of 0.87 in determining stress incontinence due to bladder neck incompetence. The Stresscath was at least as accurate as the urethral pressure profile in the diagnosis of stress incontinence, at less capital cost.

The effect of sacral nerve stimulation for bladder control during pregnancy: a case report

Neural stimulation was used to reduce bladder hyperreflexia and incontinence in a woman with myelodysplasia. The stimulation was delivered via an electrode placed in a sacral foramen and attached to a stimulator placed subcutaneously. The patient activated the device to inhibit the bladder and deactivated it to allow voiding. The device proved to be helpful in reducing bladder hyperreflexia and its use during pregnancy did not seem to have any adverse effect.
