The reactions of RuCl2[P(C6H5) 3]3 with excesses of various aromatic amines led to six coordinate, pseudo-octahedral complexes. Thus, three equivalents of pyridazine or 3-methylpyridazine could be incorporated, or two equivalents of pyrazole or phthalazine, all as monodentate ligands. Reaction with 1,8-naphthyridine led to the incorporation of one bidentate ligand. X-ray structural data were obtained for the pyridazine, phthalazine and 1,8-naphthyridine complexes.

Despite significant advances in the catalytic direct arylation of heteroarenes, the application of this reaction to pyridines has been met with limited success. An oxidative nucleophilic arylation strategy has been developed to overcome this problem. Pyridine, pyrazine, quinolone, and related electron-deficient N-heteroarenes can be arylated at the most electrophilic site using the developed nickel-catalyzed reaction. This protocol serves as a complementary method to catalytic direct arylation reactions. Less is more: Pyridine, pyrazine, quinoline and related electron-deficient N-heteroarenes can be arylated at the most electrophilic site using organozinc reagents through nickel catalysis.

As circulating monocytes enter the site of disease, the local microenvironment instructs their differentiation into tissue macrophages (MPhi). To identify mechanisms that regulate MPhi differentiation, we studied human leprosy as a model, since M1-type antimicrobial MPhi predominate in lesions in the self-limited form, whereas M2-type phagocytic MPhi are characteristic of the lesions in the progressive form. Using a heterotypic co-culture model, we found that unstimulated endothelial cells (EC) trigger monocytes to become M2 MPhi. However, biochemical screens identified that IFN-gamma and two families of small molecules activated EC to induce monocytes to differentiate into M1 MPhi. The gene expression profiles induced in these activated EC, when overlapped with the transcriptomes of human leprosy lesions, identified Jagged1 (JAG1) as a potential regulator of MPhi differentiation. JAG1 protein was preferentially expressed in the lesions from the self-limited form of leprosy, and localized to the vascular endothelium. The ability of activated EC to induce M1 MPhi was JAG1-dependent and the addition of JAG1 to quiescent EC facilitated monocyte differentiation into M1 MPhi with antimicrobial activity against M. leprae. Our findings indicate a potential role for the IFN-gamma-JAG1 axis in instructing MPhi differentiation as part of the host defense response at the site of disease in human leprosy.

Fibrosis is the formation of abnormal scar tissue following repeated tissue injury, leading to the disruption of extracellular matrix homeostasis with loss of tissue architecture and function. In the developed world, fibrosis is a leading cause of morbidity and mortality whereby multiple organs can be individually affected. Over the last decade the alphav integrins have emerged as a target class with significant potential to intervene in multi-organ fibrosis due to their role in the activation of the key pro-fibrotic cytokine, transforming growth factor-beta. Although drug discovery efforts have been directed at members of this integrin sub-family in the past, the alphav integrins are currently undergoing a renaissance due to recent compelling target validation in fibrotic diseases. Historical drug discovery initiatives highlighted the challenges in both chemical tractability and design of robust pre-clinical and clinical studies in this area. The majority of approved drugs have targeted the alphaIIbbeta3 integrin for thrombosis, which demonstrates that only a small proportion of the integrin family have been shown to be tractable drug targets, probably as a result of their complex functional roles in both normal physiology and disease pathobiology. Recently, there has been large investment by the pharmaceutical industry into alphav-integrin drug discovery research that has facilitated the advancement of new small molecule therapeutics to clinical use. The aim of this chapter is to summarise the evidence for the alphav integrins in fibrotic disease, offer insight into alphav inhibitor small molecule drug design and provide an overview of the competitor and clinical landscapes to date.

We present a theoretical study of the electronic absorption spectrum of the 2-ferrocenyl-1,8-naphthyridine (FcNP) complex using the time-dependent density functional theory (TD-DFT) approach. The calculations were carried out at the DFT/LANL2DZ(Fe)/6-31++G(d) level of theory with nine DFT functionals of the type GGA (PBE, B97D), HGGA (B3LYP, PBE0), HMGGA (M05, M06) and range-separated (wB97XD, CAM-B3LYP, LC-wPBE) in the condensed phase (CH2Cl2). The experimental spectrum for FcNP presents three electronic absorption bands (A, B, C) in the UV region and one band (D) in the visible region. We found that there is no unique functional that reproduces the entire electronic spectrum. GGA and LC-wPBE functionals predict large errors (up to 0.57 eV) for the UV bands. On the contrary, HGGA (PBE0), HMGGA (M05, M06) and range-separated (wB97XD, CAM-B3LYP) functionals give small errors for these bands, 0.18, 0.12 and 0.25 eV, respectively. Band D is well described by all the functionals with errors up to 0.26 eV, except by the M05 and M06 functionals, which fail in this region with significant errors (0.52 and 0.56 eV). The analysis of the excitation energies shows that the PBE0, wB97XD and CAM-B3LYP functionals predict the best agreement with the experimental data. The two stronger bands (A, B) in the UV region are assigned to a ligand?ligand charge transfer (L-LCT) that involves the cyclopentadienyl rings (Cp) and the naphthyridine fragment (NP), and then associated with pi ? pi? electronic transitions. The two weaker bands (C, D) are assigned to a charge transfer from ligand (Cp) to metal (Fe)-ligand (NP) (L-MLCT) which is mainly addressed through the dxy and dz2 atomic orbitals, respectively. No charge transfer is observed between metal and NP ligand. It was shown that the theoretical methods used for understanding the electronic absorption properties of FcNP were adequate because the results showed an excellent agreement with experimental ones.

A number of 4-aminopyrazolo[3,4-b]pyridines 5-carboxylic acid esters (2-8) were synthesized and evaluated for their binding affinity at the A1, A2A, and A3 adenosine receptors (AR), in bovine cortical membranes, as well as for their affinity toward human A1AR (hA 1AR). Some of the new compounds were characterized by a high affinity and selectivity toward the A1 receptor subtype, showing a significant improvement in comparison with other pyrazolo-pyridines previously reported in the literature. In particular the methyl ester 2h as well as the isopropyl ester 5h, both of them bearing a p-methoxyphenylethylamino side chain at the position 4, presented K1 values of 6 and 7 nM, respectively. To rationalize the relationships between structure and affinity of the novel compounds, a 3D QSAR model was also generated starting from compounds belonging to different classes of known A1AR antagonists. 2005 American Chemical Society.

Reactions of the dinuclear palladium(I) complex [Pd2Cl2(RNC)4] (R = 2,4,6-Me3C6H2) 1 with the N-donor compounds 2,2?-bipyridyl (bipy), 1,10-phenanthroline (phen), and 2,9-dimethyl-1,10-phenanthroline (dmphen) gave dipalladium(I) complexes with chelating N-donor ligands, [Pd2(RNC)2L2] [PF6]2 (L = bipy 2, phen 3 or dmphen 4). The structures of 2 and 4 were characterized by X-ray crystallography. The cation of 2 is composed of two Pd atoms joined by a sigma bond [2.518(3) A] each of which has a square-planar co-ordination involving a terminal isocyanide and a chelating bipy ligand. Complex 3 is expected to have a structure similar to 2 on the basis of spectroscopic data. Complex 4 exhibits a distorted dinuclear structure due to the steric bulk of the N-donor ligand. The Pd-Pd bond length is 2.599(2) A. Each dmphen ligand chelates to a Pd atom and the isocyanide acts as a semibridging ligand. The similar reactions of complex 1 with 2,2?-biquinoline (bquin) and 1,8-naphthyridine (napy) afforded the isocyanide-bridged dipalladium(I) complexes, [Pd2(mu-RNC)2(bquin)2]-[PF6] 2 5 and [Pd2(mu-RNC)2(napy)4][PF6] 2 6, in 24-36% yields. Complex 6 comprises a dinuclear palladium(I) core bridged by two isocyanide ligands [Pd-Pd 2.747(4) A] with four terminal napy ligands co-ordinated in a monodentate fashion.

A series of naphthyridine and naphthyridinone allosteric dual inhibitors of Akt1 and 2 have been developed. These compounds have been optimized to have potent dual activity against the activated kinase as well as the activation of Akt in cells. One molecule in particular, compound 17, has potent inhibitory activity against Akt1 and 2 in vivo in a mouse lung and efficacy in a tumor xenograft model.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1,8-Diazanaphthalene, you can also check out more blogs about254-60-4
