Synthesis and electronic properties of 3,7-dianilino substituted N-hexyl phenothiazines

3,7-Diaminophenothiazine derivatives are readily synthesized via two-fold Buchwald-Hartwig coupling of 10-hexyl 3,7-dibromo-10H-phenothiazine with a series of primary and secondary anilines and amines. All derivatives possess two reversible oxidations at low potentials with remarkable semiquinone formation constants. The electronic structure of this novel class of phenothiazinyl- oligoanilines is additionally studied and rationalized by DFT computations and correlation studies between selected experimental and computational electronic data.

Synthesis of isoxazolyl oxadiazolines and thiazolidinones

4-(5-Methyl-3-isoxazolyl)-3,5-diaryl-Delta2-1,2,4-oxadiazolines have been prepared by benzonitrile oxide addition to 3-benzalamino-5-methyl isoxazoles. The Schiff bases have been obtained by the condensation of aromatic aldehydes with 3-amino-5-methyl isoxazole. The reaction between these Schiff bases and 2-mercaptopropanoic acid (thiolactic acid) in refluxing benzene, provides a mixture of diastereomeric thiazolidinones. Similarly the condensation of 4-benzalamino-3-methyl-5-styrylisoxazoles with 2-mercaptopropanoic acid also led to the formation of a mixture of diasteromeric thiazolidinones. Attempts have been made to separate them by using column chromatography and their ratios determined through 1H NMR data.

G protein-coupled receptors as promising cancer targets

G protein-coupled receptors (GPCRs) regulate an array of fundamental biological processes, such as growth, metabolism and homeostasis. Specifically, GPCRs are involved in cancer initiation and progression. However, compared with the involvement of the epidermal growth factor receptor in cancer, that of GPCRs have been largely ignored. Recent findings have implicated many GPCRs in tumorigenesis, tumor progression, invasion and metastasis. Moreover, GPCRs contribute to the establishment and maintenance of a microenvironment which is permissive for tumor formation and growth, including effects upon surrounding blood vessels, signaling molecules and the extracellular matrix. Thus, GPCRs are considered to be among the most useful drug targets against many solid cancers. Development of selective ligands targeting GPCRs may provide novel and effective treatment strategies against cancer and some anticancer compounds are now in clinical trials. Here, we focus on tumor related GPCRs, such as G protein-coupled receptor 30, the lysophosphatidic acid receptor, angiotensin receptors 1 and 2, the sphingosine 1-phosphate receptors and gastrin releasing peptide receptor. We also summarize their tissue distributions, activation and roles in tumorigenesis and discuss the potential use of GPCR agonists and antagonists in cancer therapy.

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.

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.

Biodegradation of sulfamethoxazole by a bacterial consortium of Achromobacter denitrificans PR1 and Leucobacter sp. GP

In the last decade, biological degradation and mineralization of antibiotics have been increasingly reported feats of environmental bacteria. The most extensively described example is that of sulfonamides that can be degraded by several members of Actinobacteria and Proteobacteria. Previously, we reported sulfamethoxazole (SMX) degradation and partial mineralization by Achromobacter denitrificans strain PR1, isolated from activated sludge. However, further studies revealed an apparent instability of this metabolic trait in this strain. Here, we investigated this instability and describe the finding of a low-abundance and slow-growing actinobacterium, thriving only in co-culture with strain PR1. This organism, named GP, shared highest 16S rRNA gene sequence similarity (94.6?96.9%) with the type strains of validly described species of the genus Leucobacter. This microbial consortium was found to harbor a homolog to the sulfonamide monooxygenase gene (sadA) also found in other sulfonamide-degrading bacteria. This gene is overexpressed in the presence of the antibiotic, and evidence suggests that it codes for a group D flavin monooxygenase responsible for the ipso-hydroxylation of SMX. Additional side reactions were also detected comprising an NIH shift and a Baeyer?Villiger rearrangement, which indicate an inefficient biological transformation of these antibiotics in the environment. This work contributes to further our knowledge in the degradation of this ubiquitous micropollutant by environmental bacteria.
