Synthesis and Biological Evaluation of Chromenylurea and Chromanylurea Derivatives as Anti-TNF-a agents that Target the p38 MAPK Pathway

A series of 1-aryl-3-(2H-chromen-5-yl)urea and 1-aryl-3-(chroman-5-yl)urea derivatives were designed, synthesized and evaluated for their inhibitory activities towards TNF-a production in lipopolysaccharide-stimulated THP-1 cells. The most active compound, 40g, inhibited TNF-a release with an IC50 value of 0.033 muM, which is equipotent to that of BIRB796 (IC50 = 0.032 muM).

Selective CB2 receptor agonists. Part 2: Structure-activity relationship studies and optimization of proline-based compounds

Through a ligand-based pharmacophore model (S)-proline based compounds were identified as potent cannabinoid receptor 2 (CB2) agonists with high selectivity over the cannabinoid receptor 1 (CB1). Structure-activity relationship investigations for this compound class lead to oxo-proline compounds 21 and 22 which combine an impressive CB1 selectivity profile with good pharmacokinetic properties. In a streptozotocin induced diabetic neuropathy model, 22 demonstrated a dose-dependent reversal of mechanical hyperalgesia.

Analytical Studies on Isoxazoles. V. Colorimetric Determination of Isouron and Its Isomer with p-Dimethylaminocinnamaldehyde

Isouron (1) and its isomer, 1-(3-tert-butylisoxazol-5-yl)-3,3-dimethylurea (2), were determined by a colorimetric method with p-dimethylaminocinnamaldehyde (DACA) as the reagent.Compounds 1 and 2 were hydrolyzed to give 3-amino-5-tert-butylisoxazole (3) and 5-amino-3-tert-butylisoxazole (4), respectively, which were transformed into colored substances by reaction with DACA.The former colored product was a Schiff base but the latter product had a different absorption maximum from the corresponding Schiff base.The latter color reaction resulted in a batochromic shift as compared with Schiff base formation at the 5-position.Traces of 2 (more than 0.05 percent) in 1 could be estimated precisely together with the quantitation of 1 by making use of this batochromic effect.Keywords – isouron; 1-(3-tert-butylisoxazol-5-yl)-3,3-dimethylurea; herbicide; colorimetric assay method; p-dimethylaminocinnamaldehyde; hydrolysis of isouron; 3-amino-5-tert-butylisoxazole; 5-amino-3-tert-butylisoxazole; Schiff base.

N-(4-halo-isoxazolyl)-sulfonamides and derivatives thereof that modulate the activity of endothelin

N-(4-halo-isoxazolyl)sulfonamides and methods for modulating or altering the activity of the endothelin family of peptides are provided. In particular, N-(4-halo-3-isoxazolyl)sulfonamides and N-(4-halo-5-isoxazolyl)benzenesulfonamides and methods for inhibiting the binding of an endothelin peptide to an endothelin receptor or increasing the activity of endothelin peptides by contacting the receptor with a sulfonamide are provided.

General procedure: To a stirred solution of ynamide 4a (57.0 mg, 0.2 mmol) in DCE (2.0 mL, 0.1 M) was added isoxazol-5-amine 8a (21.6 mg, 0.22 mmol, 1.1 equiv), followed by AgNTf2 (3.9 mg, 5 mol %). The resulting mixture was placed into an oil bath of 80 C with stirring for 2 h generally, monitoredby TLC. After completion, the reaction mixture was cooled and the desired product was precipitated. The solid was filtered and washed with DCM twice, then dried in a vacuum drying oven at 50 C for 24 h to give the pure pyrrole product 10aa, 75.8 mg, 99% yield. For products 10ab-ae, 10ka-la, the purification method was as follows: evaporation of volatiles under reduced pressure to give the residue, which was suffered from column chromatographyon silica gel (petrol ether/ethyl acetate 1:1-1:2, v/v) to afford the pure pyrrole.

a. Formation of 1-[3-(1,1-dimethylethyl)-5-isoxazolyl]-3-methylurea A 50 milliliter flask with a magnetic stirring bar was charged with 1.3 grams (0.0093 mole) of 3-(1,1-dimethylethyl)-5-isoxazolamine and 25 milliliters of benzene. To this was added 1.7 grams of methyl isocyanate and one (1) drop of triethylamine; and the mixture was allowed to stand overnight, after which it was heated to reflux for 7.5 hours and then allowed to stand at room temperature for two (2) days. Thin layer chromatography showed only partial reaction, so a trace of 4-dimethylaminopyridine and several milliliters of methyl isocyanate were added and the mixture heated at reflux for 4.5 hours. The mixture was then concentrated on a rotary evaporator to give 2.6 grams of a viscous red brown oil. Chromatography on alumina with chloroform/ethyl acetate monitored by TLC gave fractions containing a single component. These fractions were combined and evaporated to give 0.67 gram of a pale yellow solid of 1-[3-(1,1-dimethylethyl)-5-isoxazolyl]-3-methylurea, M.P. 188¡ã-196¡ã C., which showed a molecular ion at 197 in the mass spectrum.
