Structure-based virtual screening of a commercial library identified pentanedioic acid derivatives (6 and 13b) as a kind of novel scaffold farnesyltransferase inhibitors (FTIs). Chemical modifications of the lead compounds, biological assays and analysis of the structure-activity relationships (SAR) were conducted to discover more potent FTIs. Some of them displayed excellent inhibition against FTase, and among them, the most active compound 13n with an IC50 value of 0.0029 μM and SAR analysis might be helpful to the discovery of more potent FTIs.

The invention provides specific small molecule compounds that allosterically regulate the activity or modulate protein-protein interactions of AGC protein kinases and the Aurora family of protein kinases, methods for their production, pharmaceutical compositions comprising same, and their use for preparing medicaments for the treatment and prevention of diseases related to abnormal activities of AGC protein kinases or of protein kinases of the Aurora family.
4-benzimidazolyl-3-phenylbutanoic acids as novel pif-pocket-targeting allosteric inhibitors of protein kinase PKCΧ

Protein kinase inhibitors with an allosteric mode of action are expected to reach, in many cases, higher selectivity for the target enzyme than ATP-competitive compounds. Therefore, basic research is aiming at identifying and establishing novel sites on the catalytic domain of protein kinases which might be targeted by allosteric inhibitors. We previously published the first structure-activity relationships (SARs) for allosteric activators of protein kinase PDK1. Here, we present the design, synthesis, and SAR data on a series of novel compounds, 4-benzimidazolyl-3-phenylbutanoic acids, that inhibit the atypical protein kinace C (PKC) Χ via binding to the PIF-pocket. Key positions were identified in the compounds that can be modified to increase potency and selectivity. Some congeners showed a high selectivity toward PKCΧ, lacking inhibition of the most closely related isoform, PKC1, and of further AGC kinases. Furthermore, evidence is provided that these compounds are also active toward cellular PKCΧ without loss of potency compared to the cell-free assay.

Enantioselective alcoholysis of meso-glutaric anhydrides catalyzed by Cinchona-based sulfonamide catalysts

supporting information; experimental part, p. 2211 - 2217 (2010/11/19)
The bifunctional Cinchona-based sulfonamide catalysts showed the highest levels of enantioselectivity reported to date in the alcoholytic desymmetrization of meioglutaric anhydrides. Density functional theory (DFT) computational studies provide detailed insight into the observed sense of enantioselectivity. Moreover, detailed experimental studies and single crystal X-ray analysis confirmed that these bifunctional organocatalysts 3 do not form Hbonded self-aggregates in both solution and solid state. The synthetic utility of this methodology was also demonstrated in the synthesis of pharmaceutically important γ-amino acids, such as (S)-pregabalin. Of the many asymmetric syntheses of enantiomerically pure (S)-pregabalin reported to date, our synthesis requires the least number of and the simplest steps.
An efficient synthesis of (R)- and (S)-baclofen via desymmetrization
Ji, Lei,Ma, Yuheng,Li, Jin,Zhang, Liangren,Zhang, Lihe
scheme or table, p. 6166 - 6168 (2009/12/26)
A short and highly enantioselective synthesis of both enantiomers of GABA agonist baclofen in four steps with total yields of 32.8% [for (S)-isomer] and 35.1% [for (R)-isomer] is reported. The key step involved desymmetrization of cyclic anhydride with mo
A one-pot synthesis of 3-arylglutaric anhydrides by reaction of ketene with aromatic aldehydes and ketones
Matsunaga, Hirokazu,Ikeda, Kiyoshi,Iwamoto, Ken-ichi,Suzuki, Yumiko,Sato, Masayuki
experimental part, p. 2334 - 2336 (2009/09/06)
Aromatic aldehydes and ketones react with ketene under Lewis acid catalysis to produce β-lactones, which in situ react with another molecule of ketene to produce 3-arylglutaric anhydrides. The mechanism, scope, and limitation of this one-pot synthesis of 3-substituted glutaric anhydrides are discussed.

We describe a series of 2,5 thiazole containing compounds, which are potent antagonists of the integrin αvβ3 and show selectivity relative to the other integrins, such as αIIbβ 3 and αvβ6. These analogs were demonstrated to have high bioavailability relative to other relative heterocyclic analogs.
Enzymatic desymmetrization of 3-arylglutaric acid anhydrides
Fryszkowska, Anna,Komar, Marta,Koszelewski, Dominik,Ostaszewski, Ryszard
, p. 2475 - 2485 (2007/10/03)
Optically active (R)- and (S)-3-arylglutaric acid monoesters 3 were synthesized in quantitative yields and good stereoselectivities by lipase-catalyzed desymmetrization of the corresponding 3-arylglutaric anhydrides 2 with alcohols. It was observed that the stereochemical outcome of the reaction was influenced by the substituents present on the aromatic ring. The influence of the enzyme, alcohol, and solvent was systematically examined. Absolute configurations of the monoesters 3 were assigned by chemical correlation to corresponding lactones 4.
