Discovery of histone deacetylase 8 selective inhibitors
摘要:
We have developed an efficient method for synthesizing candidate histone deacetylase ( HDAC) inhibitors in 96-well plates, which are used directly in high-throughput screening. We selected building blocks having hydrazide, aldehyde and hydroxamic acid functionalities. The hydrazides were coupled with different aldehydes in DMSO. The resulting products have the previously identified 'cap/linker/biasing element' structure known to favor inhibition of HDACs. These compounds were assayed without further purification. HDAC8-selective inhibitors were discovered from this novel collection of compounds. (C) 2011 Elsevier Ltd. All rights reserved.

the electronic properties of silylethers, thus enabling selective oxidation of benzylic and allylic silylethers, despite steric factors. A subsequent one-pot reduction accomplishes the formal deprotection to the corresponding benzylic and allylic alcohols. This catalytic system allows the direct oxidative desymmetrization of bis-benzylic and bis-allylic silylethers to access synthetically useful

chemoselective one-pot cleavage and oxidation of silyl ethersusing catalytic amount of TsOH·H2O and IBX in DMSO. The oxidation of primary alkyl TBS ethers afforded the corresponding aldehydes in 51–94% yields, in the presence of aryl TBS, MOM, and PMB ethers, as well as N-Boc and acetonide groups. Secondary benzyl TBS ethers bearing aryl TBS ethers were also oxidized to ketones in moderate yields. A

A fluorous analogue of TBAF has been developed for its use in the clean removal of silicon-derived protecting groups. Purification of the crude mixtures by fluorous solid-phase extractions allowed alcohols, amines, and carboxylic acids to be obtained in high purity, with no need of chromatographic separations. The moderate reactivity of fluorous TBAF was exploited in selective deprotections of several bifunctional molecules.
