Design, synthesis, and biological activity of novel PPARgamma ligands based on rosiglitazone and 15d-PGJ2

To develop novel PPARgamma ligands, we synthesized thirteen 3-{4-(2-aminoethoxy)phenyl}propanoic acid derivatives, which are designed based on the structures of rosiglitazone and 15d-PGJ2. Among these compounds, compound 9 was found to be as potent as rosiglitazone in a binding assay and a preadipocyte differentiation test. Molecular modeling suggested that the nonyl group of 9 interacted with hydrophobic amino acid residues constructing the hydrophobic region of PPARgamma protein where the alkyl chain of 15d-PGJ2 is expected to be located.

Glucosamine-based primary amines as organocatalysts for the asymmetric aldol reaction

Glucosamine derivatives have been synthesized starting from commercially available N-acetyl-D-glucosamine/glucosamine hydrochloride and have been employed successfully as efficient organocatalysts for the direct asymmetric aldol reaction between cyclohexanone and aryl aldehydes having diversified substituents. Furthermore, the anomeric effect of various groups present at the anomeric position on the catalytic activity of these organocatalysts was also studied.

Structures of triterpenoids from the leaves of Lansium domesticum

From the methanolic extract of the leaves of Lansium domesticum, three new onoceranoid-type triterpenoids, lansium acids X?XII and a new cycloartane-type triterpene, lansium acid XIII, were isolated. The chemical structures of the isolated new compounds were elucidated on the basis of chemical/physicochemical evidence. For new onoceranoid-type triterpenoids, the absolute configurations were established by comparison of experimental and predicted electronic circular dichroism (ECD) data. The isolated onoceranoid-type triterpenoids showed antimutagenic effects in the Ames assay against 3-amino-1,4-dimethyl-5H-pyrido[4,3-b]indole (Trp-P-1).

Dimolybdenum complexes of bis(2-pyridyl)amine (Hdpa) ligand and its anion (dpa-); Transformation of chelating eta2-Hdpa to bridging eta2-dpa-

The reaction of trans-Mo2(O2CCR3)2X 2(PPh3)2 with 1 equiv. of Hdpa (Hdpa=bis(2-pyridyl)amine) in CH2Cl2 afforded the complex cis-Mo2(O2CCR3)2X 2(eta2-Hdpa) (R=H, X=Cl, 1; R=H, X=Br, 2; R=F, X=Cl, 3, R=F, X=Br, 4). Layering of a Mo2(O2CCF3)4 solution in CH2Cl2 with Hdpa in ether produced red and yellow crystals, which were characterized as Mo2(eta2-dpa)4 (5), and Mo2(O2CCF3)4(eta 1-HO2CCF3)2 ¡¤ 2Hdpa (6), respectively. Complex 5 can also be prepared by reaction of trans-Mo2(O2CCR3)2X 2(PPh3)2 with excess Hdpa. Their UV-Vis and IR spectra have been recorded and the structures of 4, 5 and 6 have been determined. The Hdpa ligand in 4 is coordinated to the metal centers via two terminal pyridine nitrogen atoms with a cis-N conformation. The dpa- ligands in 5 are bridged to the metal centers via one terminal nitrogen atom and the central nitrogen atom. The aligned-N conformation of the dpa- ligand is stabilized by both the intramolecular MoN and C-HN interactions. In 6, the CF3COOH ligands coordinate to the metal centers in the axial positions with eta1-bonding modes and the Hdpa molecules adapt cis-N conformations.

Synthesis of n-alkyl terminal halohydrin esters from acid halides and cyclic ethers or thioethers under solvent- and catalyst-free conditions

An efficient and eco-friendly protocol has been developed for the preparation of n-alkyl terminal halohydrin esters under solvent- and catalyst-free conditions. Ring opening of cyclic ethers by organic acid halides affords the 1,4- and 1,5-halohydrins, OH-protected by different acyl groups. The green reaction conditions, simple work-up procedures, high yields and broad substrate scope of the reaction highlight the positive features of this method. This journal is

Highly selective c-Jun N-terminal kinase (JNK) 2 and 3 inhibitors with in vitro CNS-like pharmacokinetic properties prevent neurodegeneration

In this Letter, we describe the discovery of selective JNK2 and JNK3 inhibitors, such as 10, that routinely exhibit >10-fold selectivity over JNK1 and >1000-fold selectivity over related MAPKs, p38alpha and ERK2. Substitution of the naphthalene ring affords an isoform selective JNK3 inhibitor, 30, with approximately 10-fold selectivity over both JNK1 and JNK2. A naphthalene ring penetrates deep into the selectivity pocket accounting for the differentiation amongst the kinases. Interestingly, the gatekeeper Met146 sulfide interacts with the naphthalene ring in a sulfur-pi stacking interaction. Compound 38 ameliorates neurotoxicity induced by amyloid-beta in human cortical neurons. Lastly, we demonstrate how to install propitious in vitro CNS-like properties into these selective inhibitors.

Synthesis and characterization of monosaccharide derivatives and application of sugar-based prolinamides in asymmetric synthesis

For the first time, the beta-anomer of N-acetylglucosamine derivative methyl 2-acetamido-3,4,6-tri-O-benzyl-2-deoxy-beta-D-glucopyranoside (9b) was synthesized, isolated, and used in the synthesis of sugar-based primary amine 4b. Sugar-based primary amine 5a, an anomeric pair of monosaccharide derivatives 6a and 6b, and precursors to all these compounds were also synthesized, isolated, and well studied by standard spectroscopic methods, including 2D NMR spectroscopy experiments such as 1H-1H COSY and HSQC. Then sugar-based primary amines 4a, 5a, 6a, and 6b were converted into the corresponding prolinamide organocatalysts (i.e., 1a, 2a, 3a, and 3b) in high yields. The catalytic activity of these sugar-based prolinamide organocatalysts was demonstrated in asymmetric aldol reactions in various solvents and at different temperatures. The oraganocatalyst 3a was shown to be an efficient and powerful organocatalyst for the enantioselective aldol reaction of various cyclic or acyclic ketones with aromatic aldehydes in a mild and facile reaction, which gave the corresponding aldol adducts with high levels of diastereoselectivity (up to 99:1) and enantioselectivity (up to >99 %) in almost all cases.
