Chelation versus cyclometalation in a cationic Dppn-RhI complex – A unique rearrangement of norbornadiene via C-H activation of the pyridazine ring

The tetradentate ligand 3,6-bis(2-pyridyl)pyridazine (dppn) was treated with cationic RhI precursors. The mononuclear complexes [Rh(dppn)(NBD)]BF4 (1) and [Rh(dppn)(COD)]BF4 (5) were obtained in quantitative yield when treating dppn with [Rh(NBD)2]BF4 or [Rh(COD)2]BF4 respectively. Treatment of 1 with a second equivalent of the metal precursor [Rh(NBD)(CH3CN)2]BF4 led to the dinuclear complex [Rh2(dppn-H)(NBD)(eta-C7H9) (CH3CN)2](BF4)2 (2) [dppn-H = mu-C4HN2(C5H4N)2-3, 6], a mixed RhI-RhIII complex. This complex arises from C-H activation of the pyridazine ring, followed by a unique rearrangement of the NBD ligand. Compound 2 was also obtained directly by treating dppn with 2 equiv. of [Rh(NBD)(CH3CN)2]BF4. The complex [Rh2(dppn-H)(NBD)(eta1-C7H9) (CH3OH)2(CH3CN)](BF4)2 (4) was obtained by dissolving 2 in methanol. Full characterization of compounds 1, 4 and 5 included an investigation by 1H-15N GHMBC NMR spectroscopy and single-crystal X-ray structures of 1 and 4.

Discovery of imidazopyridazines as potent Pim-1/2 kinase inhibitors

High levels of Pim expression have been implicated in several hematopoietic and solid tumor cancers, suggesting that inhibition of Pim signaling could provide patients with therapeutic benefit. Herein, we describe our progress towards this goal using a screening hit (rac-1) as a starting point. Modification of the indazole ring resulted in the discovery of a series of imidazopyridazine-based Pim inhibitors exemplified by compound 22m, which was found to be a subnanomolar inhibitor of the Pim-1 and Pim-2 isoforms (IC50values of 0.024?nM and 0.095?nM, respectively) and to potently inhibit the phosphorylation of BAD in a cell line that expresses high levels of all Pim isoforms, KMS-12-BM (IC50?=?28?nM). Profiling of Pim-1 and Pim-2 expression levels in a panel of multiple myeloma cell lines and correlation of these data with the potency of compound 22m in a proliferation assay suggests that Pim-2 inhibition would be advantageous for this indication.

Dirhodium-catalyzed C-H arene amination using hydroxylamines

Primary and N-alkyl arylamine motifs are key functional groups in pharmaceuticals, agrochemicals, and functional materials, as well as in bioactive natural products. However, there is a dearth of generally applicablemethods for the direct replacement of aryl hydrogens with NH2/NH(alkyl) moieties. Here, we present a mild dirhodium-catalyzed C-H amination for conversion of structurally diverse monocyclic and fused aromatics to the corresponding primary and N-alkyl arylamines using NH2/NH(alkyl)-O-(sulfonyl)hydroxylamines as aminating agents; the relatively weak RSO2O-N bond functions as an internal oxidant. The methodology is operationally simple, scalable, and fast at or below ambient temperature, furnishing arylamines in moderate-to-good yields and with good regioselectivity. It can be readily extended to the synthesis of fused N-heterocycles.

Compositions and methods of inhibiting N-acylethanolamine-hydrolyzing acid amidase

Compounds and pharmaceutical compositions are contemplated that inhibit N-acyl-ethanolamine-hydrolyzing acid amidase (NAAA) to so increase the concentration of the substrate of NAAA, palmitoylethanolamide (PEA). NAAA inhibition is contemplated to be effective to alleviate conditions associated with a reduced concentration of PEA. Among other uses, various NAAA inhibitors are especially contemplated as therapeutic agents in the treatment of inflammatory diseases.

Adenosine receptors: Synthesis, structure-activity relationships and biological activity of new 6-amino purine derivatives

The synthesis and evaluation of the biological activity of a series of pyridazin-3(2H)-one derivatives is reported. The compounds were tested in radioligand binding assays for affinity at A1 and A(2A) adenosine receptors in bovine brain cortical membranes, and bovine brain striatal membranes, respectively. None of the compounds shows any affinity towards A(2A) receptor, while compounds in which the 6-chloro-pyridazin-3(2H)-one or 6-phenyl-pyridazin-3(2H)-one group is linked through a chain of two carbon atoms in the 6 position of the adenosine, show a good affinity towards A1 adenosine receptor, particularly compound 8 in which a phenyl-pyridazinone group is present shows highest affinity with K(i) values 6.6 nM.
