The resulting complexes were formulated via EA, IR, and SCXRD, and the TGA of all the complexes was also evaluated. The X-ray studies reveal that these complexes present mononuclear to dinuclear structures with tetrahedral geometry around each Zn2+, and octahedral/pentagonal bipyramidal geometry for Cd2+ The Hdmpzs in all compounds are coordinated only in monodentate fashion with its neutral N. The carboxylates at 1-4 and 3-9 function only as unidentate coordination units, the CO2- in 5 has the chelating bidentate coordination mode. Compound 6 contains both unidentate bridging and bidentate chelating COO-. The free carboxylate 0 at 2-4 and 7-8 accept the intramolecular N-H…O H-bonds, at 1 and 7 the uncoordinated O participate in the intermolecular N-H…O H-bonds. For 6 there is intermolecular N H-0 H-bond from the NHCO and H2O, and intramolecular N-H…O H-bonds from the NH at Hdmpz, the NHCO (acceptor), and one 0 at the bismonodentate coordinated COO-. One anion at 6 also gives the intramolecular N H-H-bonds from the NHCO(donor) and one O at the bismonodentate coordinated COO-. The intermolecular N-H…O H-bonds are from the phenol at both 4 and 5, and from the H2O at 9. The CH3 at Hdmpz in all compounds are participated in the noncovalent bonds except 3. The intricate intra-and intermolecular N-H…O and O-H…O H-bonds as well as C-H…N, C-H, O..O, Br…O, CH3…CH, CH2…C, CH3…C, C-H..O, CH2…O, CH3…O, C-H…S, C-H…CH3- rt, and pi…phi associations are elucidated by the X-ray crystallographic studies, which unite the discrete units into high-dimensional ordered supramolecular structures.

Two new coordination compounds viz. [Ni(2,6-PDC)(Hdmpz)(H2O)(2)]center dot H2O (1) and [Zn(3-CNpy)(2)Cl-2] (2) (2,6-PDC = 2,6-pyridinedicarboxylate, Hdmpz = 3,5-dimethylpyrazole, 3-CNpy = 3-cyanopyridine) have been synthesized and characterized using elemental analysis, thermogravimetric analysis, electronic, infrared spectroscopy and single crystal X-ray diffraction techniques. Crystal structure analyses reveal the presence of supramolecular assemblies involving interesting dimers with unconventional contacts in the compounds. DFT (Density Functional Theory) calculations on the supramolecular dimers in the crystal structure of 1 reveal that the sum of contributions of anion-pi, pi-pi and other long range interactions due to the approximation of the bulk monomers is energetically significant. Molecular Electrostatic Potential (MEP) surface and Quantum Theory of Atoms in Molecules (QTAIM) analyses on the interesting supramolecular dimers of the crystal structures of 2 reveal the presence of unconventional anion center dot center dot center dot pi contacts involving coordinated chlorido ligands and C-H center dot center dot center dot pi(nitrile) interactions involving the pi-system of the nitrile moiety of 3-cyanopyridine. Remarkably, Atoms in Molecules analysis also confirms the existence of energetically significant unconventional anti-parallel nitrile center dot center dot center dot nitrile interaction in the crystal structure of 2. Cell cytotoxicity of the compounds performed in Dalton’s lymphoma (DL) malignant cancer cell line showed effective potency with negligible cytotoxicity in normal cells (similar to 12%). It is interesting that compound 1has excellent cytotoxic potency with IC50 closer to cisplatin and can bind different biological targets with similar signalling pathways. Structure activity relationship (SAR) analyses of 1 and 2 based on pharmacophore modelling reveal that the molecular features associated with the structures of the compounds play important role in the biological activities.

The complex [MoO(O-2)(2)(pyrazole)(2)] (1) is an effective catalyst for the oxidation of organic sulfides (methyl-phenylsulfide and diphenylsulfide). Reactions can be run in water as the only medium, at low temperature (25 degrees C), with low catalyst loadings (0.2 mol%) and excellent H2O2 efficiency with no significant non-productive decomposition of the oxidant. Under conditions that favor sulfone formation, the overall process, including isolation of the precipitated product (by filtration or centrifugation) and recycling of the aqueous phase con-taining the catalyst, can be performed in the absence of organic or ionic liquid solvents. Catalytic results with the recycled aqueous phase were the same as those obtained in the first cycle. With water as the sole solvent, 1 is a superior catalyst to the 3,5-dimethylpyrazole complexes [MoO(O-2)(2)(dmpz)(2)] (2) and [Hdmpz](4)[Mo8O25.8(O-2)(0.2)(dmpz)(2)]center dot 4H(2)O (3). Crystal structures for 1 and 3 are presented.

Deregulation of the transcriptional repressor BCL6 enables tumorigenesis of germinal center B-cells, and hence BCL6 has been proposed as a therapeutic target for the treatment of diffuse large B-cell lymphoma (DLBCL). Herein we report the discovery of a series of benzimidazolone inhibitors of the protein-protein interaction between BCL6 and its co-repressors. A subset of these inhibitors were found to cause rapid degradation of BCL6, and optimization of pharmacokinetic properties led to the discovery of 5-((5-chloro-2-((3R,SS)-4,4-difluoro-3,5-dimethylpiperi din-1-yl) pyrimidin-4-yl) amino)-3-(3-hydroxy-3-methylbutyl)-1-methyl-1,3-dihydro-2H-benzo[d]imidazol-2-one (CCT369260), which reduces BCL6 levels in a lymphoma xenograft mouse model following oral dosing.

Reported herein is the pyrazole-directed iridium-catalyzed enantioselective borylation of unbiased methylene C-H bonds at the position beta to a nitrogen center. The combination of a chiral bidentate boryl ligand, iridium precursor, and pyrazole directing group was responsible for the high regio- and enantioselectivity observed. The method tolerated a vast array of functional groups to afford the corresponding C(sp(3))-H functionalization products with good to excellent enantioselectivity.

A facile one-pot protocol for the synthesis of 2-amino-3-cyanopyridins using SBA-15@Triazine/H(5)PW(10)V(2)O(40)as an efficient catalyst under ultrasonic conditions has been developed. The nanohybrid catalyst was prepared by the chemical anchoring of Keggin heteropolyacid H(5)PW(10)V(2)O(40)onto the surface of SBA-15 mesoporous silica modified with 2-APTS -4,6-bis(3,5-dimethyl-1H-pyrazol- 1-yl)-1,3,5-triazine (ADMPT) linker. Then the nanohybrid was used as a green, efficient, eco-friendly, and highly recyclable catalyst for the one-pot and multi-component synthesis of 2-amino-3-cyanopyridin derivatives from the reaction of aldehydes, malononitrile, cyclic ketones and ammonium acetate under ultrasound waves with good to excellent yields (79-95%) and in a short span of time. This nanocatalyst was characterized by using FT-IR, XRD, SEM, TEM, BET, and EDX techniques.

Prototropic tautomerism was used as a tool for the reductive dehalogenation of (hetero) aryl bromides and iodides, or dehalogenative sulfonation of (hetero) aryl chlorides and fluorides, using sodium sulfite as the sole reagent in an aqueous medium. This protocol does not require a metal or phase transfer catalyst and avoids using organic solvent as the reaction medium. This method is especially suitable for substrates that readily tautomerize (such as 2-or 4-halogenated aminophenols and 4-halogenated resorcinols), for which dehalogenation or sulfonation proceeds under mild reaction conditions (<= 60 degrees C). As sodium sulfite is an inexpensive, safe, and environmentally less hazardous reagent, this method has at least three potential applications: (i) in the deprotection of halogens as protecting groups, using sodium sulfite as a reducing agent; (ii) in the sulfonation of aromatic halides under mild reaction conditions avoiding hazardous and corrosive reagents/ solvents; and (iii) in the transformation of toxic halogenated aromatics into less harmful compounds.

Catalytic enantioselective alpha-fluorination reactions of carbonyl compounds are among the most powerful and efficient synthetic methods for constructing optically active alpha-fluorinated carbonyl compounds. Nevertheless, alpha-fluorination of alpha-nonbranched carboxylic acid derivatives is still a big challenge because of relatively high pK(a)values of their alpha-hydrogen atoms and difficulty of subsequent synthetic transformation without epimerization. Herein we show that chiral copper(II) complexes of 3-(2-naphthyl)-l-alanine-derived amides are highly effective catalysts for the enantio- and site-selective alpha-fluorination ofN-(alpha-arylacetyl) andN-(alpha-alkylacetyl) 3,5-dimethylpyrazoles. The substrate scope of the transformation is very broad (25 examples including a quaternary alpha-fluorinated alpha-amino acid derivative). alpha-Fluorinated products were converted into the corresponding esters, secondary amides, tertiary amides, ketones, and alcohols with almost no epimerization in high yield.
