Discovery of 1,4-disubstituted 3-cyano-2-pyridones: A new class of positive allosteric modulators of the metabotropic glutamate 2 receptor

The discovery and characterization of compound 48, a selective and in vivo active mGlu2 receptor positive allosteric modulator (PAM), are described. A key to the discovery was the rational exploration of the initial HTS hit 13 guided by an overlay model built with reported mGlu2 receptor PAM chemotypes. The initial weak in vitro activity of the hit 13 was quickly improved, although compounds still had suboptimal druglike properties. Subsequent modulation of the physicochemical properties resulted in compounds having a more balanced profile, combining good potency and in vivo pharmacokinetic properties. Final refinement by addressing cardiovascular safety liabilities led to the discovery of compound 48. Besides good potency, selectivity, and ADME properties, compound 48 displayed robust in vivo activity in a sleep-wake electroencephalogram (sw-EEG) assay consistent with mGlu2 receptor activation, in accordance with previous work from our laboratories.

Measurement and prediction of enthalpies of combustion and formation of oxygen and nitrogen heterocycles

Enthalpies of combustion and formation are reported for six O-heterocyclic and four N-heterocyclic compounds in crystalline or liquid phases. By the use of estimated enthalpies of fusion and vaporisation, liquid and gas enthalpies of formation were derived and compared with values predicted directly by the NIST Structures and Properties program and by the Pedley method. The results are discussed in relation to ring strain energies and the strength and weaknesses of the predictive methods are compared.

Synthesis of modified Trichinella spiralis disaccharide epitopes and a comparison of their recognition by chemical mapping and saturation transfer difference NMR

A rat monoclonal antibody 9D4 raised against the cell surface N-glycan of the parasite Trichinella spirallis protects rats against further infection. The terminal disaccharide beta-d-Tyvp(1?3)beta-d-GalNAcp (2) represents the immunodominant portion of the antigenic determinant. Chemical mapping of the antibody binding site by functional group modification employing monodeoxy and mono-O-methyl congeners identified key polar contacts and topography of the bound disaccharide. We report here a comparison of the chemical mapping studies with the antigen topography inferred from saturation transfer difference (STD) NMR experiments. During chemical mapping several congeners of compound 2 showed substantially enhanced binding. Pairing of these functional group modifications to create derivatives 6 and 7 did not show additive free energy gains and STD NMR data point to small variations in mode of binding as a probable cause. Improved syntheses of disaccharides 2-7 are reported.

EXPERIMENTAL STUDIES OF THE ANOMERIC EFFECT. PART I. 2-SUBSTITUTED TETRAHYDROPYRANS.

Variable temperature (1)H and (13)C n.m.r. studies in CFCl3/CDCl3 of equilibria in 2-substituted- and 2-substituted-4-methyl-tetrahydropyranes have given conformational enthalpy differences and conformational entropy differences for chloro, methoxy, hydroxy and methylamino substituents.For DeltaHoa->e, the values obtained, in kcal /mol, were 1.67 (Cl), 0.03 (OCH3), -0.63 (OH) and -1.75 (NHCH3); for DeltaSoa->e the values obtained, in cal K-1mol-1 were -1.69 (Cl), -2.52 (OCH3), -2.50 (OH) and -0.60 (NHCH3).The trend in DeltaHo values confirms the importance of antiperiplanar n-?* stabilisation as a contributor to the explanation of the anomeric effect, and supports a suggestion that endo- and exo-anomeric effects which occur in the same conformation are competitive.A variable temperature (13)C n.m.r. study of (Me-(13)C)-4-methyl-tetrahydropyran in CD2Cl2 has given a conformational enthalpy difference (DeltaHoa->e) of -1.86 kcal/mol and a conformational entropy difference (DeltaSoa->e) of -0.07 cal K-1mol-1 for a methyl substituent at the 4-position of a tetrahydropyran.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 7525-64-6 is helpful to your research., Synthetic Route of 7525-64-6

Simple sulfinate synthesis enables C-H trifluoromethylcyclopropanation

A simple method to convert readily available carboxylic acids into sulfinate salts by employing an interrupted Barton decarboxylation reaction is reported. A medicinally oriented panel of ten new sulfinate reagents was created using this method, including a key trifluoromethylcyclopropanation reagent, TFCS-Na. The reactivity of six of these salts towards C-H functionalization was field-tested using several different classes of heterocycles.

Accessing iron amides from dimesityliron

A new phase of dimesityliron has been crystallized from diethylether; the crystal structure shows a dinuclear complex with co-crystallized solvent. Crystalline [Fe2(mes)2(mu2-mes)2]·Et2O is a convenient starting material and reacts with di(2-pyridyl)amine to yield rare iron di(2-pyridyl)amido complexes. Crystal structures of air-sensitive [Fe2(mes)2(dpa)2], [Fe2(dpa)3Cl] and [Fe4(dpa)6O] were determined. [Fe4(dpa)6O] is known, and the dinuclear complexes [Fe2(mes)2(dpa)2] and [Fe2(dpa)3Cl] represent only the second and third reports of homometallic iron dpa- complexes. Long Fe … Fe distances of 3.043(1) and 3.104(2) A in [Fe2(mes)2(dpa)2] and [Fe2(dpa)3Cl], respectively, and very unsymmetrically coordinated amido groups, indicate that the iron atoms are not involved in M-M bonding. This fact, and the relatively low coordination numbers of the high spin Fe(II) atoms are consistent with sensitivity of these compounds towards O2. DFT calculations were employed to rationalize the formation of the unusual architectures displayed by the dpa- complexes of iron.
