Farnesoid X receptor (FXR), a bile acid-activated nuclear receptor, regulates the metabolism of bile acid and lipids as well as maintains the stability of internal environment. FXR was considered as a therapeutic target of liver disorders, such as drug-induced liver injury, fatty liver and cholestasis. The previous reported FXR partial agonist 6 was a suitable lead compound in terms of its high potent and low molecular size, while the docking study of compound 6 suggested a large unoccupied hydrophobic pocket, which might be provided more possibility of structure-activity relationship (SAR) study. In this study, we have performed comprehensive SAR and molecular modeling studies based on lead compound 6. All of these efforts resulted in the identification of a novel series of FXR partial agonists. In this series, compound 41 revealed the best activity and strong interaction with binding pocket of FXR. Moreover, compound 41 protected mice against acetaminophen-induced hepatotoxicity by the regulation of FXR-related gene expression and improving antioxidant capacity. In summary, these results suggest that compound 41 is a promising FXR partial agonist suitable for further investigation.

Pd-catalyzed, highly selective C(sp2)-Br bond coupling reactions of o-(or m-, or p-) chloromethyl bromobenzene with arylboronic acids

Highly selective C(sp2)–C(sp2) cross-coupling of dihalogenated hydrocarbons comprising C(sp2)–Br and C(sp3)–Cl bonds with arylboronic acids is reported. This highly selective coupling reaction of the C(sp2)–Br bond is successfully achieved using Pd(OAc)2 and PCy3·HBF4 as the palladium source and ligand, respectively. A series of chloromethyl-1,1′-biphenyl compounds are obtained in moderate-to-excellent yields. Moreover, this protocol can be extended to the one-pot dual arylation of 1-bromo-4-(chloromethyl)benzene with two arylboronic acids, leading to diverse unsymmetrical 4-benzyl-1,1′-biphenyl derivatives.

The free fatty acid receptor 1 (FFA1) has emerged as an attractive anti-diabetic target that mediates glucose-stimulated insulin secretion. Several FFA1 agonists have been reported, but many of them possessed somewhat high lipophilicity and/or molecular weight. Herein, we describe the identification of sulfone-carboxylic acid moiety with the multiple advantages of reducing lipophilicity, cytotoxicity and β-oxidation associated with compound 2. Further structure-activity relationship study based on the previleged scaffolds led to the discovery of 2-{(4-[(2’-chloro-[1,1’-biphenyl]-3-yl)methoxy]phenyl)sulfonyl}acetic acid (compound 20), which showed a better balance than compound 2 in terms of physicochemical properties, cytotoxicity profiles and pharmacokinetic properties. Subsequent in vivo studies demonstrated that compound 20 robustly improves the glucose tolerance both in normal and type 2 diabetic models without the risk of hypoglycemia. Compared to the high risk of TAK-875 induced liver toxicity, there was no significant adverse effects such as hepatic and renal toxicity were observed in the chronic toxicity studies of compound 20 even at the higher dose.

A copper-catalyzed Suzuki-Miyaura coupling of benzyl halides with arylboronates is described. Varieties of primary benzyl halides as well as more challenging secondary benzyl halides with β hydrogens or steric hindrance could be successfully converted into the corresponding products. Thus it provides access to diarylmethanes, diarylethanes and triarylmethanes. This journal is the Partner Organisations 2014.

The palladium-catalyzed decarboxylative benzylation of α-cyano aliphatic carboxylate salts with benzyl electrophiles was discovered. This reaction exhibits good functional group compatibility and proceeds under relatively mild conditions. A diverse range of quaternary, tertiary and secondary β-aryl nitriles can be conveniently prepared by this method. Copyright
Dichloro-bis(aminophosphine) complexes of palladium: Highly convenient, reliable and extremely active suzuki-miyaura catalysts with excellent functional group tolerance
Bolliger, Jeanne L.,Frech, Christian M.
experimental part, p. 4075 - 4081 (2010/08/05)
Dichloro-bis(aminophosphine) complexes are stable depot forms of palladium nanoparticles and have proved to be excellent SuzukiMiyaura catalysts. Simple modifications of the ligand (and/or the addition of water to the reaction mixture) have allowed their formation to be controlled. Dichlorobis[1- (dicyclohexylphosphany1)piperidine]palladium (3), the most active catalyst of the investigated systems, is a highly convenient, reliable, and extremely active Suzuki catalyst with excellent functional group tolerance that enables the quantitative coupling of a wide variety of activated, nonactivated, and deactivated and/or sterically hindered functionalized and heterocyclic aryl and benzyl bromides with only a slight excess (1.1-1.2 equiv) of arylboronic acid at 80°C in the presence of 0.2 mol % of the catalyst in technical grade toluene in flasks open to the air. Conversions of >95% were generally achieved within only a few minutes. The reaction protocol presented herein is universally applicable. Side-products have only rarely been detected. The catalytic activities of the aminophosphine-based systems were found to be dramatically improved compared with their phosphine analogue as a result of significantly faster palladium nanoparticle formation. The decomposition products of the catalysts are dicyclohexylphosphinate, cyclohexylphosphonate, and phosphate, which can easily be separated from the coupling products, a great advantage when compared with non-water-soluble phosphine-based systems.

A series of novel N3/8-disubstituted-3,8-diazabicyclo[3.2.1]octanes in order to improve the in vitro activity of the prototype 3,8-bis[2-(3,4,5-trimethoxyphenyl)pyridyl-4-yl)methylpiperazine (1) were synthesized and evaluated by assays of growth inhibition against several tumor cell lines. Compounds 2a,b,f and m demonstrated not only growth-inhibitory activities against leukemia cancer cells, but also fairly good activities against the growth of certain solid tumors. Among them, 2a is the most potent one with IC50 values in the low micromolar range. Moreover, compound 2a has been selected for in vitro testing on MCF-7 cell to evaluate the mode of action of this lead compound.
