Abstract
Two series of novel 3-cyano-2-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxo) pyridines and 3-cyano-2-(2,3,5-tri-O-acetyl-β-D-ribofuranosyloxy)-4-trifluromethyl-6-phenyl pyridine were synthesized using efficient microwave methods. The targeted compounds were obtained in high yields by reacting 2-(1H)-pyridone or its salt with activated sugars using SiO₂ under solvent-free conditions. Ammonolysis of the resulted acetylated nucleosides produced 3-cyano-2-(β-D-glucopyranosyloxo)-pyridines and 3-cyano-2-(β-D-ribofuranosyloxy)-4-trifluoromethyl-6-phenyl pyridine. These new products were fully characterized using 1D and 2D NMR. These compounds were screened for their antibacterial activities against G(+) and G(-) bacteria and some found to exhibit better antibacterial activities than the control drug.

Abstract
The synthesis of a novel series of 4-arylhydrazono-5-methyl-1,2-dihydropyrazol-3-ones 4a-h, and their N (2)-alkyl and acyclo, glucopyranosyl, and ribofuranosyl derivatives is described. K(2)CO(3) catalyzed alkylation of 4a-h with allyl bromide, propargyl bromide, 4-bromobutyl acetate, 2-acetoxyethoxymethyl bromide, and 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide proceeded selectively at the N (2)-position of the pyrazolinone ring. Glycosylation of 4a with 1,2,3,5-tetra-O-acetyl-β-D-ribofuranose under Vorbruggen glycosylation conditions gave the corresponding N (2)-4-arylhydrazonopyrazolone ribofuranoside 9a in good yield. Conventional deprotection of the acetyl protected nucleosides furnished the corresponding 4-arylhydrazonopyrazolone nucleosides in good yields. Selected numbers of the newly synthesized compounds were screened for antimicrobial activity. Compounds 4b, 12a, and 14 d showed moderate activities against Aspergillus flavus, Penicillium sp., and Escherichia coli.

Abstract
Reaction of pyridin-2(1H)-one 1 with 4-bromobutylacetate (2), (2-acetoxyethoxy)methyl bromide (3) gave the corresponding nicotinonitrile O-acyclonucleosides, 4 and 5, respectively. Deacetylation of 4 and 5 gave the corresponding deprotected acyclonucleosides 6 and 7, respectively. Treatment of pyridin-2(1H)-one 1 with 1,3-dichloropropan-2-ol (8), epichlorohydrin (10) and allyl bromide (12) gave the corresponding nicotinonitrile O-acyclonucleosides 9, 11, and 13, respectively. Furthermore, reaction of pyridin-2(1H)-one 1 with the propargyl bromide (14) gave the corresponding 2-O-propargyl derivative 15, which was reacted via [3+2] cycloaddition with 4-azidobutyl acetate (16) and [(2-acetoxyethoxy)methyl]azide (17) to give the corresponding 1,2,3-triazole derivatives 18 and 19, respectively. The structures of the new synthesized compounds were characterized by using IR, (1)H, (13)C NMR spectra, and microanalysis. Selected members of these compounds were screened for antibacterial activity.

Abstract
A new series of substituted 2(1H)-pyridones (4a-i) and their glucosides (5, 6a-e) were prepared as potential agents against leukemia (HL-60) cells. Glucosides (5,6a-e) were synthesized using three independent methods. Microwave protocol as an ecologically new method was used to synthesize the target compounds. Structures of the new products were confirmed using one- and two-dimensional NMR spectroscopy. In vitro exposure of pyridones substituted at position 4 with a 2-thienyl or 2-(trifluoromethyl)phenyl were found to exhibit high antiproliferation activities; in particular, 3-cyano-4-(thien-2'-yl)-6-(4''-chlorophenyl)-2(1H)-pyridone (4c) and its glucoside analogue (6c) had the highest activity.

Abstract
A series of S-glycosyl and S-alkyl derivatives of 4-amino-3-mercapto-6-(2-(2-thienyl)vinyl)-1,2,4-triazin-5(4H)-one (1)were synthesized using different halo compounds such as preacetylated sugar bromide, 4-bromobutylacetate, 2-acetoxyethoxy-methyl bromide, 3-chloropropanol, 1,3-dichloro-2-propanol, epichlorohydrin, allyl bromide, propargyl bromide, phthalic and succinic acids in POCl3. The structures of the synthesized compounds have been deduced from their elemental analysis and spectral (IR, 1H-NMR, and 13C-NMR) data. Some of the synthesized compounds were screened as anticancer agents. Significant anticancer activities were observed in vitro for some members of the series, and compounds 4-Amino-3-(3-hydroxypropylthio)-6-(2-(2-thienyl)vinyl)-1,2,4-triazin-5(4H)-one (12) and 3-(4-Oxo-3-(2-(2-thienyl)vinyl)-4H-[1,3,4]thiadiazolo-[2,3-c][1,2,4]tr-iazin-7-yl)propanoic acid (18) are active cytotoxic agents against different cancer cell lines.

Abstract
5-Acetyl-2-aryl-6-methyl-4-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosylmercapto)pyramidines 3a-c were obtained by the reaction of 5-acetyl-2-aryl-6-methyl-pyrimidine thiol 1a-c with 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranosyl bromide (2) in aq. KOH/acetone. The reaction of 1a-c with peracetylated galactose 5 and peracetylated ribose 8 under MW irradiation gave 5-acetyl-2-aryl-6-methyl-4-(2,3,4,6-tetra-O-acetyl-beta-D-galactopyranosylmercapto)pyrimidine 6a-c and 5-acetyl-2-aryl-6-methyl-4-(2,3,5-tri-O-acetyl-beta-D-ribofuranosylmercapto)pyrimidines 9a-c. The deprotection of 3a-c, 6a-c, and 9a-c in the presence of methanol and TEA/H(2)O yielded the deprotected products 4a-c, 7a-c, and 10a-c. The structures of the compounds were confirmed by using IR, (1)H, (13)C spectra and microanalysis. Selected members of these compounds were screened for antimicrobial activity.
