(alpha-Fe2O3)-MCM-41-SO3H as a novel magnetic nanocatalyst for the synthesis of N-aryl-2-amino-1,6-naphthyridine derivatives

The new (alpha-Fe2O3)-MCM-41-SO3H catalyst was prepared directly through the reaction of chlorosulfonic acid with silica-coated nanoparticles (alpha-Fe2O3)-MCM-41 and used as a magnetically recyclable catalyst for an efficient one-pot synthesis of N-aryl-2-amino-1,6-naphthyridine derivatives. The catalyst with 10 wt% of loaded iron oxide nanoparticles could be recovered from the reaction mixture by an external magnet and reused without significant decrease in activity even after 5 runs.

Naphthyridines as Novel BET Family Bromodomain Inhibitors

Bromodomains (BRDs) are small protein domains found in a variety of proteins that recognize and bind to acetylated histone tails. This binding affects chromatin structure and facilitates the localisation of transcriptional complexes to specific genes, thereby regulating epigenetically controlled processes including gene transcription and mRNA elongation. Inhibitors of the bromodomain and extra-terminal (BET) proteins BRD2-4 and T, which prevent bromodomain binding to acetyl-modified histone tails, have shown therapeutic promise in several diseases. We report here the discovery of 1,5-naphthyridine derivatives as potent inhibitors of the BET bromodomain family with good cell activity and oral pharmacokinetic parameters. X-ray crystal structures of naphthyridine isomers have been solved and quantum mechanical calculations have been used to explain the higher affinity of the 1,5-isomer over the others. The best compounds were progressed in a mouse model of inflammation and exhibited dose-dependent anti-inflammatory pharmacology.

Design, Synthesis, and Biological Evaluation of 4-Quinoline Carboxylic Acids as Inhibitors of Dihydroorotate Dehydrogenase

We pursued a structure-guided approach toward the development of improved dihydroorotate dehydrogenase (DHODH) inhibitors with the goal of forming new interactions between DHODH and the brequinar class of inhibitors. Two potential residues, T63 and Y356, suitable for novel H-bonding interactions, were identified in the brequinar-binding pocket. Analogues were designed to maintain the essential pharmacophore and form new electrostatic interactions through strategically positioned H-bond accepting groups. This effort led to the discovery of potent quinoline-based analogues 41 (DHODH IC50 = 9.71 +/- 1.4 nM) and 43 (DHODH IC50 = 26.2 +/- 1.8 nM). A cocrystal structure between 43 and DHODH depicts a novel water mediated H-bond interaction with T63. Additional optimization led to the 1,7-naphthyridine 46 (DHODH IC50 = 28.3 +/- 3.3 nM) that forms a novel H-bond with Y356. Importantly, compound 41 possesses significant oral bioavailability (F = 56%) and an elimination t(1/2) = 2.78 h (PO dosing). In conclusion, the data supports further preclinical studies of our lead compounds toward selection of a candidate for early-stage clinical development.

Multi-Step Synthesis of Biologically Active Novel N-Benzyl-3,5-Bis(Arylidene)-Piperidin-4-Ones and Some Derived Bicyclic and Tricyclic Ring Systems as Macromolecules

This study reports the synthesis of some new bicyclic and tricyclic heterocyclic macromolecules incorporated pyrano[3,2-c]pyridine, 1,6-naphthyridine, and pyrimidonaphthyridine rings starting from new dienones, N-benzyl-3,5-bis(arylidene)-piperidin-4-ones. The chemistry involved the cyclocondensation of dienones with malononitrile in the presence of piperidine yielded the target 2-aminopyranopyridine-3-carbonitriles. The reaction of dienones with malononitrile or ethyl cyanoacetate in the presence of excess ammonium acetate afforded the corresponding 2-aminonaphthyridines and/or 2-oxonaphthyridine derivatives, respectively, in good yields. The 2,4-disubstituted pyrimido[4,5-b][1,6]naphthyridines were successfully achieved from the reaction of the 2-aminonaphthyridine derivatives with the appropriate reagents. The structures of the isolated products were determined by elemental analysis and spectral methods (FT-IR, H-1-NMR, and C-13-NMR). The cytotoxicity of some of the prepared derivatives was also investigated. [GRAPHICS] .
