Fatty acid-binding protein 4 (FABP4) and fatty acid-binding protein 5 (FABP5) are promising therapeutic targets for the treatment of various metabolic diseases. However, the weak potency, low selectivity over FABP3, or poor pharmacokinetic profiles of currently reported dual FABP4/5 inhibitors impeded further research. Here, we described the characterization of a series of dual FABP4/5 inhibitors with improved metabolic stabilities and physicochemical properties based on our previous studies. Among the compounds, D9 and E1 exhibited good inhibitory activities against FABP4/5 and favorable selectivity over FABP3 in vitro. In cell-based assays, D9 and E1 exerted a decrease of FABP4 secretion, a strong anti-lipolytic effect in mature adipocytes, and suppression of MCP-1 expression in THP-1 macrophages. Moreover, D9 and E1 possessed good metabolic stabilities in mouse hepatic microsomes and acceptable pharmacokinetics profiles in ICR mice. Further in vivo experiments showed that D9 and E1 could potently decrease serum FABP4 levels and ameliorate glucose metabolism disorders in obese diabetic db/db mice. These results demonstrated that D9 and E1 could serve as lead compounds for the development of novel anti-diabetic drugs.

Fatty acid binding protein 4 (FABP4) and fatty acid binding protein 5 (FABP5) are mainly expressed in adipocytes and/or macrophages and play essential roles in energy metabolism and inflammation. When FABP4 function is diminished, FABP5 expression is high

Electrophilic halogenation is used to produce a wide variety of halogenated compounds. Previously reported methods have been developed mainly using a reagent-based approach. Unfortunately, a suitable "catalytic" process for halogen transfer reactions has yet to be achieved. In this study, arylamines have been found to generate an N-halo arylamine intermediate, which acts as a highly reactive but selective catalytic electrophilic halogen source. A wide variety of heteroaromatic and aromatic compounds are halogenated using commercially available N-halosuccinimides, for example, NCS, NBS, and NIS, with good to excellent yields and with very high selectivity. In the case of unactivated double bonds, allylic chlorides are obtained under chlorination conditions, whereas bromocyclization occurs for polyolefin. The reactivity of the catalyst can be tuned by varying the electronic properties of the arene moiety of catalyst.

The relative stabilities of three conformational isomers of 2,2′-binaphthalene-1,1′-diol diisobutyrate and the energy barriers to rotation about the pivotal aryl-aryl bond and the two aryl-oxygen bonds were investigated by variable-temperature NMR spectroscopy in conjunction with DFT computations. The experimental and calculated data were found to be in very good agreement and provide new insights into the dynamic stereochemistry of BINOL-derived tropos ligands.

A stereodynamic probe for determination of the absolute configuration and enantiomeric composition of chiral amines, diamines, amino alcohols, amino acids, and α-hydroxy carboxylic acids is described. The chirality sensing is based on spontaneous asymmetric transformation of the first kind with stereolabile binaphtholate boron and zinc complexes. The substrate binding and chiral amplification processes yield a distinctive chiroptical sensor output at high wavelength that can be used for rapid and accurate ee detection of minute sample amounts.

The introduction of 1,2-bis[(o-anisyl)-(phenyl)phosphino]ethane (DiPAMP) as a P-stereogenic ligand for rhodium(I)-catalyzed hydrogenation by Knowles et al. came after their evaluation of several diphosphines. However, no in-depth study was carried out on incorporating various substituents on its P-o-anisyl groups. In this work, we have prepared a large series of enantiopure and closely related DiPAMP analogues possessing various substituents (MeO, TMS, t-Bu, Ph, fused benzene ring) on the o-anisyl rings. The new ligands were evaluated in rhodium-catalyzed hydrogenation of several model substrates: methyl α-acetamidoacrylate, methyl (Z)-α-acetamidocinnamate, methyl (Z)-β-acetamidocrotonate, dimethyl itaconate, and atropic acid. They displayed enhanced activities and increased enantioselectivities, particularly the P-(2,3,4,5-tetra-MeO-C6H)-substituted ligand (4MeBigFUS). Interestingly enough, 88% ee was obtained in the hydrogenation of atropic acid using the Rh-(4MeBigFUS) catalyst under mild conditions (10 bar H2, room temperature) versus 7% ee using Rh-DiPAMP. Conversely, the ligand possessing P-(2,6-di-MeO-C6H3) groups proved to slow down considerably the hydrogenation. X-Ray structures of their corresponding Rh complexes are presented and discussed.
