Potent mGluR5 antagonists: pyridyl and thiazolyl-ethynyl-3,5-disubstituted-phenyl series.

ABSTRACT: We report the synthesis of four series of 3,5-disubstituted-phenyl ligands targeting the metabotropic glutamate receptor subtype 5: (2-methylthiazol-4-yl)ethynyl (1a-j,), (6-methylpyridin-2-yl)ethynyl (2a-j), (5-methylpyridin-2-yl)ethynyl (3a-j,), and (pyridin-2-yl)ethynyl (4a-j,). The compounds were evaluated for antagonism of glutamate-mediated mobilization of internal calcium in an mGluR5 in vitro assay. All compounds were found to be full antagonists and exhibited low nanomolar to subnanomolar activity.

Photoconductive Properties and Electronic Structure in 3,5-Disubstituted 2-(2'-Pyridyl)Pyrroles Coordinated to a Pd(II) Salicylideneiminate Synthon.

Project description:The synthesis and the electrochemical, photophysical, structural, and photoconductive properties of three new heteroleptic Pd(II) complexes with various 3',5'- disubstituted-2-(2'-pyridil) pyrroles H(N^N) as coordinated ligands are reported. The coordination of the metal center was completed by a functionalized Schiff base H(O^N) used as an ancillary ligand. The [(N^N)Pd(O^N)] complexes showed highly interesting photoconductive properties which have been correlated to their electronic and molecular structures. Theoretical density functional theory (DFT) and time-dependent DFT calculations were performed, and the results were confronted with the organization in crystalline phase, allowing to point out that the photoconductive properties are mainly a consequence of an efficient intramolecular ligand-to-metal charge transfer, combined to the proximity between the central metal and the donor moieties in the solid-state molecular stacks. The reported results confirm that these new Pd(II) complexes form a novel class of organometallic photoconductors with intrinsic characteristics suitable for molecular semiconductors applications.

4-(Dimethyl-amino)phenyl ethynyl telluride.

Project description:The title compound, C(10)H(11)NTe, is the first organyl ethynyl telluride, R-Te-C C-H, to be structurally characterized. In the L-shaped mol-ecule, the aryl moiety, viz. Me(2)NC(6)H(4)Te, is almost perpendicular to the Te-C C-H fragment. The Te-Csp(2) bond [2.115 (3) Å] is significantly longer than the Te-Csp bond [2.041 (4) Å]. The Te-C C group is approximately linear [Te-C-C = 178.5 (4)° and C C = 1.161 (5) Å], while the coordination at the Te atom is angular [C-Te-C = 95.92 (14)°]. In the crystal structure, there are Csp-H⋯N hydrogen bonds which are perpendicular to the CNMe(2) group; the N atom displays some degree of pyramidalization. Centrosymmetrically related pairs of mol-ecules are linked by Te⋯π(ar-yl) inter-actions, with Te⋯Cg = 3.683 (4) Å and Csp-Te⋯Cg = 159.1 (2)° (Cg is the centroid of the benzene ring). These inter-actions lead to the formation of zigzag ribbons which run along c and are approximately parallel to (110).

3,5-Difluoro-phenyl phenyl sulfone.

Project description:In the title compound, C(12)H(8)F(2)O(2)S, which is a precursor of functionalised poly(aryl-ene ether sulfone) polymers, the dihedral angle between the aromatic ring planes is 84.43 (8)°. In the crystal structure, aromatic π-π stacking [centroid-centroid separations = 3.808 (3) and 3.867 (3) Å] helps to establish the packing. A short C-H⋯F contact also occurs.

4-Ethynyl-N,N-di-phenyl-aniline.

Project description:The asymmetric unit of the title compound, C20H15N, comprises two crystallographically independent mol-ecules (A and B). In each mol-ecule, the N atom adopts an approximately trigonal planar geometry, lying 0.009?(1) or 0.003?(1)?Å from the plane defined by the C atoms of the aromatic substituents to which it is attached. In the crystal, mol-ecules are linked via C-H?? inter-actions, forming a three-dimensional structure.

Structure-activity relationships of substituted 1-pyridyl-2-phenyl-1,2-ethanediones: potent, selective carboxylesterase inhibitors.

Project description:Inhibition of intestinal carboxylesterases may allow modification of the pharmacokinetics/pharmacodynamic profile of existing drugs by altering half-life or toxicity. Since previously identified diarylethane-1,2-dione inhibitors are decidedly hydrophobic, a modified dione scaffold was designed and elaborated into a >300 member library, which was subsequently screened to establish the SAR for esterase inhibition. This allowed the identification of single digit nanomolar hiCE inhibitors that showed improvement in selectivity and measured solubility.

Discovery of a Novel 2,6-Disubstituted Glucosamine Series of Potent and Selective Hexokinase 2 Inhibitors.

Project description:A novel series of potent and selective hexokinase 2 (HK2) inhibitors, 2,6-disubstituted glucosamines, has been identified based on HTS hits, exemplified by compound 1. Inhibitor-bound crystal structures revealed that the HK2 enzyme could adopt an "induced-fit" conformation. The SAR study led to the identification of potent HK2 inhibitors, such as compound 34 with greater than 100-fold selectivity over HK1. Compound 25 inhibits in situ glycolysis in a UM-UC-3 bladder tumor cell line via (13)CNMR measurement of [3-(13)C]lactate produced from [1,6-(13)C2]glucose added to the cell culture.

4-Amino-3,5-di-2-pyridyl-4H-1,2,4-triazole.

Project description:In the crystal structure of the title compound, C(12)H(10)N(6), the mol-ecules deviate slightly from planarity. The plane of the central triazole ring makes angles of 6.13 (9) and 3.28 (10)° with the pyridyl ring planes. Intra-molecular N-H⋯N inter-actions form six-membered closed rings. The crystal packing also shows weak C-H⋯π and C-H⋯N inter-actions.

Simple two-step synthesis of 2,4-disubstituted pyrroles and 3,5-disubstituted pyrrole-2-carbonitriles from enones.

Project description:The cyclocondensation of enones with aminoacetonitrile furnishes 3,4-dihydro-2H-pyrrole-2-carbonitriles which can be readily converted to 2,4-disubstituted pyrroles by microwave-induced dehydrocyanation. Alternatively, oxidation of the intermediates produces 3,5-disubstituted pyrrole-2-carbonitriles.

Synthesis of 3,5-Bis(trifluoromethyl)phenyl-Substituted Pyrazole Derivatives as Potent Growth Inhibitors of Drug-Resistant Bacteria.

Project description:Enterococci and methicillin-resistant S. aureus (MRSA) are among the menacing bacterial pathogens. Novel antibiotics are urgently needed to tackle these antibiotic-resistant bacterial infections. This article reports the design, synthesis, and antimicrobial studies of 30 novel pyrazole derivatives. Most of the synthesized compounds are potent growth inhibitors of planktonic Gram-positive bacteria with minimum inhibitory concertation (MIC) values as low as 0.25 µg/mL. Further studies led to the discovery of several lead compounds, which are bactericidal and potent against MRSA persisters. Compounds 11, 28, and 29 are potent against S. aureus biofilms with minimum biofilm eradication concentration (MBEC) values as low as 1 µg/mL.
