Abstract
On the basis of 4-(thien-2-yl)-3-aminopyridine-2(1H)-one, the corresponding chloroacetamide and condensed 1H-pyrido[2,3-b][1,4]oxazine-2(3H)-one were synthesized by the reaction of acylation with chloroacetyl chloride. Thioureide derivatives of 3-aminopyridine-2(1H)-one were obtained by reactions with a number of isothiocyanates. It was shown that the carbamothionylmethacrylamide derivative cyclizes rather easily into substituted 1,3-thiazine. Molecular docking of synthesized derivatives for antithrombotic activity was carried out, which showed that the presence of a thiourea fragment in the pyridone core leads to an increase in affinity for the selected protein. The hemorheological study of the compounds using the in vitro model of the increased blood viscosity syndrome also showed activity at the level of the reference drug pentoxifylline.

Abstract
Sulfonamides and trimethoprim (TMP) drugs are normally used to inhibit the action of dihydropteroate synthase (DHPS) and dihydrofolate reductase (DHFR) enzymes, respectively. In this work, a new series of N-sulfonamide 2-pyridone derivatives that combine the inhibitory activities of DHPS and DHFR into one molecule were synthesized and evaluated for its in vitro antimicrobial activity and the ability to inhibit the action of both enzymes simultaneously. The synthesis was carried out via the reaction of novel benzothiazol sulfonylhydrazide with ketene dithioacetal derivatives, and the structures of the resultant compounds were confirmed using spectral and elemental techniques. Among the synthesized compounds, five compounds 3b, 5a, 5b, 11a, and 11b were found to possess significant antimicrobial activities against tested bacterial and fungi strains. The compounds were also examined for their cytotoxicity on HFB4 human dermal fibroblast cell line using MTT assay. The in vitro enzyme assay study of these compounds against DHPS and DHFR enzymes showed that compound 11a was the most potent inhibitor against both enzymes with IC50 values of 2.76 and 0.20 μg/mL, respectively. Docking studies showed that this compound has occupied both the p-aminobenzoic acid and pterin binding pockets of DHPS as well as the pterin binding pocket of DHFR. The results of these investigations confirmed that compound 11a is the most potent dual DHPS/DHFR inhibitor.

Abstract
6-Amino-5-cyano-2-oxo-N-(pyridin-2-yl)-4-(p-tolyl)-2H-[1,2'-bipyridine]-3-carboxamide and 6-amino-5-cyano-4-(4-fluorophenyl)-2-oxo-N-(pyridin-2-yl)-2H-[1,2'-bipyridine]-3-carboxamide were synthesized through three-component reaction between N1,N3-di(pyridin-2-yl)-malonamide, aldehyde and malononitrile in water using triethylamine as a base at room temperature. Synthesized compounds were characterized by using different techniques (FT-IR, NMR and X-ray diffraction). Additionally, the mentioned compounds were investigated by computational chemistry methods. Obtained results were supported with calculated results. Additionally, NLO properties and molecular docking analyses of related compounds were examined in detail. The binding modes of the compounds 4a and 4b were explored with the colchicine binding site of tubulin, from molecular docking studies, remarkable interactions have been observed for 4a and 4b near to the colchicines binding site of tubulin that may contribute to the inhibition of tubulin polymerization and anticancer activity.

Abstract
Two series of novel 5-arylazo-3-cyano-2-(2″,3″,4″,6″-tetra-O-acetyl-β-d-galacto pyranosyloxy) pyridines and 3-cyano-2-(2″,3″,4″,6″-tetra-O-acetyl-β-d-galactopyranosyloxy) pyridines were synthesized in high yields utilizing a microwave-assisted synthesis tool guided by the principles of green chemistry. The chemical structures of the new substances were confirmed on the basis of their elemental analysis and spectroscopic data (FT-IR, 1D, 2D-NMR). Activity against different bacterial strains was studied. The anticancer potential of the new compounds is also discussed. Molecular docking was used as a tool in this research work to get better insight into the possible interactions, affinities, and expected modes of binding of the most promising derivatives of the potential chemotherapeutic target (DHFR).

Abstract
A specific N-alkylation of 2-hydroxypyridines is achieved by reacting with organohalides under catalyst- and base-free conditions. The observed HX-facilitated conversion of pyridyl ether intermediates to 2-pyridone products may account for the success and specific N-alkylation of the reaction under the unexpectedly simple conditions. This new reaction may provide a useful alternative for the synthesis of 2-pyridones and analogous structures because of its >99% N-selectivity, relatively broad scopes of both substrates, and no mandatory use of catalysts and bases.

Abstract
N-Alkyl 2-pyridones and other enolizable heterocycles are important synthetic constructs, due to their prevalence in natural products and pharmaceutical targets and their capacity to serve as models for a number of biological and chemical processes. The disclosed Au(I)-catalyzed reaction utilizes 2-propargyloxypyridines to access N-alkylated 2-pyridone products derived from both 5-exo and 6-endo addition of the nitrogen to the pendent alkyne. Experimental and computational studies suggest that the desired 5-exo N-alkenyl 2-pyridonyl ethers are formed reversibly in the transformation. After extensive optimization, biaryl Au(I) catalyst 21 was found to overcome the inherent preference for the 6-endo pathway and provide the highest combination of 5-exo selectivity and yield. Herein, we report the application of this new Au(I)-catalyzed C-N bond formation to the preparation of a variety of N-alkenyl 2-pyridonyl ether analogues, which have the potential to serve as an entry point for the synthesis of complex N-alkyl 2-pyridone-containing frameworks.

Abstract
A cationic Ir(I) complex-catalyzed O-to-N-alkyl migration in 2-alkoxypyridines bearing a secondary alkyl group on the oxygen atom by C-O bond cleavage is described. The present transformation gave various N-alkylpyridones in moderate to good yields. The addition of sodium acetate played a key role in suppressing β-hydrogen elimination.

Abstract
Herein is described the design, synthesis, and enzymatic activity of a series of substituted pyrazinones as inhibitors of the TF/VIIa complex. These inhibitors were designed to explore replacement and variation of the P1 amidine described previously [J. Med. Chem.2003, 46, 4050]. The P1 needle replacements were selected based upon their reduced basicity compared to the parent phenyl amidine (pKa approximately 12). A contributing factor towards the oral bioavailability of a compound is the ionization state of the compound in the intestinal tract. The desired outcome of the study was to identify an orally bioavailable TF-VIIa inhibitor.

Abstract
We describe the structure-based design, synthesis, and enzymatic activity of a series of substituted pyrazinones as inhibitors of the TF/VIIa complex. These inhibitors contain substituents meta to the P(1) amidine designed to explore additional interactions with the VIIa residues in the so-called 'S(1) side pocket'. A crystal structure of the designed inhibitors demonstrates the ability of the P(1) side pocket moiety to engage Lys192 and main chain of Gly216 via hydrogen bond interactions, thus, providing additional possibility for chemical modification to improve selectivity and/or physical properties of inhibitors.

Abstract
Targeted 2-pyridones were selected as tissue Factor VIIa inhibitors and prepared from 2,6-dibromopyridine via a multistep synthesis. A variety of chemical transformations, including regioselective nucleophilic addition, selective nitrogen alkylation, and a Suzuki coupling, afforded the targeted tissue Factor VIIa inhibitors. The pyridone core was selected as a replacement for the pyrazinone core of noncovalent tissue Factor VIIa inhibitors and designed such that their substitution pattern would occupy and interact with the S(1), S(2), and S(3) pockets of the tissue Factor VIIa enzyme. These compounds were tested in several serine protease enzyme assays involved in the coagulation cascade exhibiting modest activity on tissue Factor VIIa with excellent selectivity over thrombin and Factor Xa. Finally, an X-ray crystal structure of inhibitor 14a bound to tissue Factor VIIa was obtained and will be described.
