Electric Literature of 1931-44-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1931-44-8, 7-Amino-1,8-naphthyridin-2(8H)-one, introducing its new discovery.

Several novel fluorogenic N-aminoacylnaphthyridine substrates were synthesized in good yield and tested for their ability to detect pathogenic bacteria in agar-based cell culture. Simple 2-N-(beta-alanyl)amino-5,7- dialkylnaphthyridine substrates were selectively hydrolysed by beta-alanylaminopeptidase expressing bacteria, but were subject to diffusion in the agar medium. Diffusion was reduced in the 2-N-(beta-alanyl)amino-7- alkylnaphthyridine substrates with longer alkyl chains, but inhibition of growth was increased. 2-N-(beta-Alanyl)amino-7-octylnaphthyridine inhibited the growth of all species tested, except for strains resistant to colistin/polymyxin, providing a rationale for the development of substrates for the selective detection of drug resistant species in clinical samples.

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.

Reference of 254-60-4, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst.

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.

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.
