Solvent- and ligand-free palladium-catalyzed amination of aryl halides

An environmentally friendly and economically favorable approach to the formation of C-N bonds is presented. The methodology is particularly interesting in that the reaction is realized under both solvent- and ligand-free conditions and involves the use of a low loading of a palladium catalyst dispersed with the reactants on a suitable solid support. The reaction proceeds rapidly under microwave irradiation. Georg Thieme Verlag Stuttgart New York.

Topical Intestinal Aminoimidazole Agonists of G-Protein-Coupled Bile Acid Receptor 1 Promote Glucagon Like Peptide-1 Secretion and Improve Glucose Tolerance

The role of the G-protein-coupled bile acid receptor TGR5 in various organs, tissues, and cell types, specifically in intestinal endocrine L-cells and brown adipose tissue, has made it a promising therapeutical target in several diseases, especially type-2 diabetes and metabolic syndrome. However, recent studies have shown deleterious on-target effects of systemic TGR5 agonists. To avoid these systemic effects while stimulating glucagon-like peptide-1 (GLP-1) secreting enteroendocrine L-cells, we have designed TGR5 agonists with low intestinal permeability. In this article, we describe their synthesis, characterization, and biological evaluation. Among them, compound 24 is a potent GLP-1 secretagogue, has low effect on gallbladder volume, and improves glucose homeostasis in a preclinical murine model of diet-induced obesity and insulin resistance, making the proof of concept of the potential of topical intestinal TGR5 agonists as therapeutic agents in type-2 diabetes.

AMIDINES. PART IX. INFLUENCE OF SUBSTITUTION AT IMINO AND AMINO NITROGEN ATOMS ON THE BASICITY OF N,N’-DIPHENYLBENZAMIDINES

A series of 15 unreported N1-metylo-N1,N2-diphenylbenzamidines containing two different substituents at phenyl rings have been synthesized and their pKa values in 99.8percent ethanol were determined.It was found that the basicities of these amidines obeyed the diparameter Hammett’s equation where the parameters are ? constants of the two substituents.The influence of substitution at either of nitrogen atoms on the basicity of amidine group is compared with formerly studied formamidines is discussed.

Light-induced cleavage of model phenylalanine conjugates based on coumarins and quinolones

In order to evaluate the application of quinolone as a new photocleavable protecting group, in comparison with coumarin, a series of model phenylalanine conjugates were prepared by reaction with chloromethylated O and N heterocycles. The photophysical properties of the resulting ester conjugates were evaluated as well as the photosensitivity under irradiation at 250, 300, 350, and 419 nm. The results obtained showed that the quinolone conjugates were readily photolysed, with complete release of the amino acid in short irradiation times and could be considered a new addition to the family of photocleavable protecting groups for the carboxylic acid function of amino acids. Springer-Verlag 2010.

A facile and efficient process for the preparation of various tertiary aminobenzenes and carbazole derivatives via photoinduced cross-coupling of amines with 1,2-diiodobenzene is reported. Mechanistic investigations indicate that the transformation proceeds via nucleo-philic addition of an amine to the benzyne intermediate accompanied with a proton transfer process, followed by an oxidative cyclization of the generated diphenylamine to furnish the corresponding carbazole products.

Abstract A series of twenty seven oxa/azaspiro[4,5]trienone derivatives were synthesized and their anticancer properties have been explored. GI50 values of all these compounds were evaluated against four types of human cancer cell lines, i.e. MCF-7 (breast), DU-145 (prostate), A549 (lung) and HepG2 (liver). Five compounds of the series exhibited good anticancer potential against MCF-7 with GI50 values less than 2 muM. Detailed biological studies of the two representative compounds 9b and 9e revealed that they arrest cell cycle in G0/G1 phase and induce mitochondria mediated apoptosis, that was further confirmed by measurement of mitochondrial membrane potential (DeltaPsim), intracellular ROS generation, caspase 9 activity and Annexin V-FITC assay. Furthermore, western blot analysis suggested that these compounds up-regulate the levels of p53, p21, p27 and Bax, and down-regulate the level of Bcl-2 confirming the apoptosis inducing properties.
