The p38 mitogen-activated protein kinase (MAPK) is a key mediator in cytokine-induced signaling events that are activated in response to a variety of extracellular stimuli such as stress factors, apoptosis, and proliferation. Therefore, the MAPK family plays an integral role in disease states including oncogenesis, autoimmune diseases, and inflammatory processes. Inhibition of these protein kin...

The title complex, [Mn2(glu)(L)2(HL)2]·0.5H2O (H2glu = glutaric acid, HL = 2-(2-chloro-6-fluorophenyl)-1Himidazo[4,5-f][1,10]phenanthroline) has been synthesized using a hydrothermal method and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal data: C162H88Cl8F8Mn4N32O9, triclinic, space group P1̄, a = 14.932(5), b = 16.414(5), c = 17.891(5) Å, α ...

As a plausible explanation for the large interindividual variability in the pharmacokinetics of the neuroleptic agent haloperidol, the contributions of CYP3A isozymes (CYP3A4 and the polymorphic CYP3A5) predominantly involved in haloperidol bioactivation to the neurotoxic pyridinium species 4-(4-Chlorophenyl)-1-[4-(4-fluorophenyl)-4-oxobutyl]-pyridinium (HPP ) were assessed in human liver micro...

Zaragozic acid A analogues are produced by an unidentified sterile fungus when it is exogenously supplied with 2-thiophenecarboxylic acid, 3-thiophenecarboxylic acid, 2-furoic acid, 2-fluorobenzoic acid, 3-fluorobenzoic acid, or 4-fluorobenzoic acid. The analogues carry 2-thiophenyl, 3-thiophenyl, 2-furyl, o-fluorophenyl, m-fluorophenyl, or p-fluorophenyl group, respectively, at C-6' of the C-1...

The synthesis and pharmacological characterization of a series of N-substituted 3-(4-fluorophenyl)tropane derivatives is reported. The compounds displayed binding characteristics that paralleled those of cocaine, and several had substantially higher affinity at cocaine recognition sites. Conjugate addition of 4-fluorophenyl magnesium bromide to anhydroecgonine methyl ester gave 2 beta-(carbomet...

Compounds that interact with microtubules, such as paclitaxel, have been shown to possess protective properties against beta-amyloid (Abeta) induced neurodegeneration associated with Alzheimer's disease. In this work, the novel agent (3R,5S,7as)-(3,5-bis(4-fluorophenyl)tetrahydro-1H-oxazolo[3,4-c]oxazol-7a-yl)methanol was investigated for effectiveness in protecting neurons against several toxi...

A series of twenty new N-[(4-arylpiperazin-1-yl)-propyl]-2-aza-spiro[4.4]nonane- and [4.5]decane-1,3-dione derivatives were synthesized and their anticonvulsant activity was evaluated in maximal electroshock (MES) and sc pentertazole (sc PTZ) tests. Their neurotoxicity was examined as well. Although no antiseizure properties of the investigated compounds were found in the MES model, eight of th...
