We report that a polyhedral oligomeric silsesquioxane (POSS) core in a dendrimer can enhance the affinity of the molecular recognition via hydrogen bonds between 1,8-naphthyridine and guanosine nucleotides. The complexation of the naphthyridine ligands with a series of guanosine nucleotides was investigated, and it is shown that the POSS core should play a significant role in the stabilization of the complexes via hydrogen bonds. Finally, we demonstrate that the 1,8-naphthyridine ligand can selectively recognize guanosine triphosphate by assisting with the POSS-core dendrimer.

On the basis of the very interesting pharmacological properties shown by the 5-amino[1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamide derivatives 1, previously described by us, we have now prepared the 5-aminoimidazo[1,2-a][1,8]naphthyridine-6-carboxamide derivatives 2a-o (a new structural class) whose tricyclic system is isosteric to that of compounds 1. Both compounds 2 and some new properly substituted compounds 1 (1f-k) now synthesized were tested in vivo for their analgesic and anti-inflammatory activities: on the whole, compounds 2 showed notable analgesic properties, whereas many compounds 1 exhibited a very potent anti-inflammatory activity, coupled to scarce analgesic activity. All the effective compounds proved to be completely devoid of acute gastrolesivity (gastric damage) in rats (at the 200 mg kg(-1) oral dose). (C) 2009 Elsevier Masson SAS. All rights reserved.

Currently, a search for selective antagonists of luteinizing hormone (LH) receptor, which are necessary to suppress steroidogenesis in hormone-dependent tumors and to prevent the ovarian hyperstimulation syndrome, is carried out. One approach to solving this problem is the development of low-molecular-weight antagonists of the allosteric site of this receptor located in its transmembrane domain. The aim of this work was to develop the heterocyclic compounds, the derivatives of thieno[2,3-d]pyrimidine (TP31), pyrimido [4,5,6-de] [1,6]naphthyridine (PP10), and pyrido[3,4-d]pyrimidine (PP17), and to study their ability to influence the functional activity of the LH receptor in the in vitro and in vivo conditions. It was shown that at micromolar concentrations TP31 suppressed stimulating effects of human chorionic gonadotropin (hCG) on the adenylyl cyclase activity in rat testicular membranes. Yet more pronounced was the suppressing effect of TP31 on the stimulating effect of TP03, an allosteric agonist of the LH receptor. This was due to a higher selectivity of the TP31 antagonist with respect to the cAMP-dependent signaling cascades, predominantly activated by TP03 and realized through Gs proteins. PP17 inhibited stimulatory effects of hCG and TP03 on the adenylyl cyclase activity to a similar extent but was less potent than TP31. Upon intratesticular (10 mg/kg) or intraperitoneal (45 mg/kg) administration to male rats, TP31 and PP17 decreased the baseline plasma level of testosterone and inhibited the testosterone production stimulated by hCG (100 IU/rat); the inhibitory effect of TP31 was much more pronounced than that of PP17. PP10 exhibited a weaker antagonistic activity than TP31 and PP17 in the in vitro and in vivo conditions. The data obtained indicate that TP31, the most active functional antagonist among the studied compounds, by binding to the allosteric site of the LH receptor, makes it less accessible to allosteric agonists and impairs the hormonal signal transduction through the LH receptor. This suggests the prospects of the development of TP31-based inhibitors of LH-dependent pathways and steroidogenesis.

A series of novel complexes of the Ru(L)(2)(CO)(2) L = 2-(3′ methoxyphenyl)-1,8-naphthyridine (complex 1), and type Ru(acac)(2)(L)(CO) with L = 2-(3′ methoxyphenyl)-1,8-naphthyridine (complex 2), 2-(2′-bromophenyl)-1,8-naphthyridine (complex 3) and 2-phenyl-1,8-naphthyridine (complex 4) was synthesized and characterized. We found that the complexes 2, 3, and 4 can be directly synthesized from Ru-3(CO)(12). The complex Ru(acac)(2)(L)(CO) L = 2-(3′ methoxyphenyl)-1,8-naphthyridine (2) was characterized by X-ray single crystal analysis which confirms the monodentate coordination mode of the 1,8-naphthyridine derivate and the cis arrangement of the acac ligands. Preliminary studies in transfer hydrogenation of acetophenone in the presence of 2-propanol show the good catalytic activity of complex 2 with 92% conversion. (C) 2012 Elsevier B.V.

A highly efficient and simple procedure has been developed for the synthesis of 9-(3-fluoro-4-methoxyphenyl)-6-aryl-[1,2,4]triazolo[4,3-a][1,8] naphthyridines by ionic liquid Cu(II) oxidative cyclization of 2-(2-(3-fluoro-4-methoxybenzylidene)hydrazinyl)-3-phenyl-1,8-naphthyridine under microwave irradiation. Synthesized compounds have been described by microanalysis, infrared, H-1 NMR spectroscopy, and mass spectrometry. Sixteen of the synthesized compounds were evaluated for their antimicrobial activity against bacteria, such as Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Klebsiella pneumoniae, as well as fungi, such as Aspergillus flavus and Fusarium oxysporum. Results of the antimicrobial screening showed that the compounds 3b, 3g, and 3j have maximal zones of inhibition against the tested bacterial strains. Docking studies were carried out for the three most active compounds 3b, 3g, and 3j along with the inactive compound 3a.

The human luteinizing hormone receptor (hLH-R) is a member of the glycoprotein hormone family of G-protein-coupled receptors (GPCRs), activated by luteinizing hormone (hLH) and essentially involved in the regulation of sex hormone production. Thus, hLH-R represents a valid target for the treatment of sex hormone dependent cancers and diseases (polycystic ovary syndrome, uterine fibroids, endometriosis) as well as contraception. Screening of the Bayer compound library led to the discovery of tetrahydrothienopyridine derivatives as novel, small molecule (SMOL) hLH-R inhibitors and to the development of BAY-298, the first nanomolar hLH-R antagonist reducing sex hormone levels in vivo. Further optimization of physicochemical, pharmacokinetic, and safety parameters led to the identification of BAY-899 with an improved in vitro profile and proven efficacy in vivo. BAY-298 and BAY-899 serve as valuable tool compounds to study hLH-R signaling in vitro and to interfere with the production of sex hormones in vivo.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 89343-06-6. Computed Properties of https://www.ambeed.com/products/89343-06-6.html.
