methodology was applied to the synthesis of a diverse 150-member library with substituents in three positions of the piperazinone core. Screening results from a luciferase reporter assay indicate that a number of library members are novel repressors of LEF-1/β-catenin-mediated transcription, and may be effective agents against colorectal tumors. Two secondary libraries (100 members each) designed from

Pharmaceuticals, kits and methods are provided for use with DPP-IV and other S9 proteases that comprise a compound with the formula: (I) where the labeled substituents are as described herein.
The high yield stepwise synthesis of 18-membered dioxa-, dithia- and diazatetralactams is described. The two key steps are: i) the dissymetrization of the reactivity of a diacid via its cyclic anhydride and ii) the activation-cyclization of the intermediate diamide diacid avoiding the high-dilution technique. Two series of diazatetralactamderivatives are prepared: bibranched compounds bearing various
描述了18元二恶英,二硫杂和二氮杂四内酰胺的高产率逐步合成。这两个关键步骤是:i)二酸通过其环酐的反应异构化,以及ii)避免高稀释技术的中间二酰胺二酸的活化环化。制备了两种二氮杂四内酰胺衍生物:带有各种取代基的双支化化合物和带有菲咯啉单元的大双环或大三环物种。通过13 C nmr和分子建模发现二氧杂内酰胺的主要构象异构体具有D 2对称性,而在真空中的双硫杂四内酰胺和固态的Boc取代的二氮杂内酰胺具有C 2对称性。

Liquidphase parallel synthesis has been developed to synthesize a novel series of iminodiacetic acid derivatives targeting the integrin receptors. This library was synthesized using a four-step reaction sequence. In each step of the sequence, the PEG-bound products were precipitated selectively and the excess reagents and the by-products were removed by simple filtration. The most notable result was
