The apical sodium dependent bile acid transporter (ASBT) is the main transporter to promote re-absorption of bile acids from the intestinal tract into the enterohepatic circulation. Inhibition of ASBT could increase the excretion of bile acids, thus increasing bile acid synthesis and consequently cholesterol consumption. Therefore, ASBT is an attractive target for developing new cholesterol-lowering drugs. In this report, a series of 1-(2,4-bifluoropheny1)-7-dialkylamino-1,8-naphthyridine-3-carboxamides were designed as inhibitors of ASBT. Most of them demonstrated potency against ASBT transport of bile acids. In particular, compound 4a(1) was found to have the best activity, resulting in 80.1% inhibition of ASBT at 10 mu mol/L.

Bacillus sp. are well-known biocontrol agents against various fungal plant pathogens. The present work was conducted for characterization of antagonistic Bacillus sp., isolated from tomato rhizosphere, and its control mechanisms against Fusarium oxysporum f. sp. lycopersici. A collection of 49 Bacillus isolates was obtained from the rhizosphere of tomato plants from infested field. Dual culture antagonism assay was carried out to assess the potential role of the strains against the pathogen. The evaluation of the strains was done for their antifungal ability and plant growth promoting properties including beta-1,3-glucanase, protease, chitinase, ammonia, siderophore, hydrogen cyanide, IAA and biofilm formation. Strain B44, identified as Bacillus sp. based on ribotyping (Accession no. MG779639), which exhibited maximum number of antifungal properties tested, was selected for further study. The strain was capable of producing hydrolytic enzymes such as beta-1,3-glucanase (15.61 U ml(-1) min(-1)), protease (1608.15 U ml(-1) min(-1)), and chitinase (129 U ml(-1) min(-1)), volatiles and non-volatile metabolites. Volatiles were extracted by solid phase micro extraction (SPME) technique. The major compounds identified by GC-MS analysis were 1,2-benzenedicarboxylic acid (23.99%), 6-undecylamine (6.61%), 2-methyloctacosane (5.91%), 9-octadecenoic acid (5.13%) and 1-tetradecanamine, N,N-dimethyl (5.05%). The prominent compounds identified by UPLC-MS were tert-butyl difluorophosphine (31.45%), 5-(4,4,5,5-tetramethyl-1, 3, 2-dioxaborolan-2-yl)-3,6-dihydro-2H-pyran (14.76%), 6-bromo-4-tert-butyl-1,1-dimethyl-1,2-dihydronaphthalene (8.35%), 2-amino-N-butyl-1,8-naphthyridine-3-carboxamide (6%), N,N-diethyl-2-[(ethylamino)methyl]-3-phenyloxirane-2-sulfonamide (5.12%). The isolate showed approx. 36% reduction in disease incidence in tomato plant under green house conditions and could serve as an efficient agent for biocontrol of wilt disease in tomato.

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.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. 709-63-7, Name is 4-(Trifluoromethyl)acetophenone, SMILES is C1=C(C=CC(=C1)C(C)=O)C(F)(F)F, belongs to naphthyridine compound.

The mechanism of oxygen activation at a dicobalt bis-mu-hydroxo core is probed by the implementation of synthetic methods to isolate reaction intermediates. Reduction of a dicobalt(III, III) core ligated by the polypyridyl ligand dipyridylethane naphthyridine (DPEN) by two electrons and subsequent protonation result in the release of one water moiety to furnish a dicobalt(II, II) center with an open binding site. This reduced core may be independently isolated by chemical reduction. Variable-temperature H-1 NMR and SQUID magnetometry reveal the reduced dicobalt(II, II) intermediate to consist of two low spin Co(II) centers coupled antiferromagnetically. Binding of O-2 to the open coordination site of the dicobalt(II, II) core results in the production of an oxygen adduct, which is proposed to be a dicobalt(III, III) peroxo. Electrochemical studies show that the addition of two electrons results in cleavage of the O-O bond.

The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research.
