The urgent need for new treatments for the chronic lung disease idiopathic pulmonary fibrosis (IPF) motivates research into antagonists of the RGD binding integrin alpha v beta 6, a protein linked to the initiation and progression of the disease. Molecular dynamics (MD) simulations of alpha v beta 6 in complex with its natural ligand, pro-TGF-beta 1, show the persistence over time of a bidentate Arg-Asp ligand-receptor interaction and a metal chelate interaction between an aspartate on the ligand and an Mg2+ ion in the active site. This is typical of RGD binding ligands. Additional binding site interactions, which are not observed in the static crystal structure, are also identified. We investigate an RGD mimetic, which serves as a framework for a series of potential alpha v beta 6 antagonists. The scaffold includes a derivative of the widely utilized 1,8-naphthyridine moiety, for which we present force field parameters, to enable MD and relative free energy perturbation (FEP) simulations. The MD simulations highlight the importance of hydrogen bonding and cation-pi interactions. The FEP calculations predict relative binding affinities, within 1.5 kcal mol(-1), on average, of experiments.

Besides, a new class of analogues of compounds 1 and 2, bearing a Mannich base moiety at the 9-position (12a-d), as well as the novel N,N-diethyl-5-(isobutylamino)-8-methyl-10-oxo-10H-pyrimido[1,2-a][1,8]naphthyridine-6-carboxamide (15) were prepared and tested. Compounds 1c-g exhibited very interesting anti-inflammatory properties in rats, whereas compounds 2b-d and 15 proved to be endowed with prevalent analgesic activity frequently associated with sedative effects in mice. On the contrary, the Mannich bases 12a-d resulted inactive. The most effective (80% inhibition of oedema) and potent (threshold dose 1.6 mg kg(-1) with 31% inhibition of oedema) anti-inflammatory compound 1d did not show gastrolesive effects following 100 mg kg(-1) oral administration in rats.

Now introduce a scientific discovery about this category, SDS of cas: 39156-41-7.

Response surface methodology was designed to optimize the process parameters for the preparation of the tosufloxacin tosylate/hydroxypropyl-beta-cyclodextrin inclusion complex by supercritical antisolvent method (SAS). The optimum inclusion conditions were temperature 45 degrees C, pressure 12 MPa, molar ratio 1:1, and mixed solvent 20% DCM, in which case the inclusion efficiency was 15.18%. Three-dimensional response plots revealed that molar ratios and mixed solvents have a more pronounced effect on inclusion efficiency than temperature and pressure. Characterization results of SEM, EDX, PXRD and FT-IR confirmed that the inclusion complex was successfully prepared, and the inclusion sites of all inclusion complexes were located on the phenyl ring A, pyrrolidine and naphthyridine ring protons. The dissolution of the inclusion complex in the pH 6.8 buffer solution was up to 68.14%, indicating that the inclusion complex prepared by the SAS process could significantly improve the dissolution of tosufloxacin tosylate.

Nine novel fused indolo [1,8] naphthyridine derivatives were synthesized using the Povarov reaction, in a one-pot system, and were fully characterized by spectroscopic techniques such as FT-IR, NMR, TOF-MS, and elemental analysis. Furthermore, their antibacterial activities against six bacterial strains were assessed. The results of the bioassay demonstrated that compounds 4a, 4c, and 4i showed good inhibitory effect with a MIC value ranging from 0.04687 to 0.09375 mu M against Bacillus cereus and Staphylococcus aureus. The toxicity of 4a-i, evaluated through mutagenicity test against Salmonella typhimurium TA 98 and TA100 strains, revealed that there was no significant increase in the number of revertant colonies in comparison with the control, sodium azide.

In a patnet, author is Andersen, Marie B., once mentioned the new application about 96-49-1.

The continuous need for the development of new small molecule anti-cancer drugs calls for easily accessible sensor systems for measuring the effect of vast numbers of new drugs on their potential cellular targets. Here we demonstrate the use of an optical DNA biosensor to unravel the inhibitory mechanism of a member of a new family of small molecule human topoisomerase I inhibitors, the so-called indeno-1,5-naphthyridines. By analysing human topoisomerase I catalysis on the biosensor in the absence or presence of added drug complemented with a few traditional assays, we demonstrate that the investigated member of the indeno-1,5-naphthyridine family inhibited human topoisomerase I activity by blocking enzyme-DNA dissociation. To our knowledge, this represents the first characterized example of a small molecule drug that inhibits a post-ligation step of catalysis. The elucidation of a completely new and rather surprising drug mechanism-of-action using an optical real time sensor highlights the value of this assay system in the search for new topoisomerase I targeting small molecule drugs.

In this study, bearing 4-methyl-7-acetamide-1,8-naphthyridyl group as the fluorophore and the receptor, we designed and synthesized a new-type Schiff-base ligand 1 which was identified as a Zn2+ fluorescent probe. The excellent selectivity and high sensitivity of this as-synthesized fluorescent probe 1 towards Zn2+ over other various biogenic metal ions were observed, for that only Zn2+ induced a drastic enhancement by about 63-fold in intensity of fluorescence emission at 504 nm, and the limit of detection (LOD) could reach 7.52 nM. Moreover, the formation of a 2:1 complex between this probe 1 and Zn2+ was determined, and the perfect invertibility and renewability of this probe 1 for sensing Zn2+ were also demonstrated. As a result, the practical applications of 1 were broadened for sensing and monitoring Zn2+ environmentally and biologically.
