الملخص الملخص [1,2,4]Triazolo[4,3-a]quinoxaline: synthesis, antiviral, and antimicrobial activities A series of novel [1,2,4]triazolo[4,3-a]quinoxa-line derivatives and their isosteres,pyrimido-quinoxaline, were synthesized as potential antiviral and antimicrobial agents. The new compounds were synthesized via aromatic nucleophilic substitution of 4-chloro-8-menthyI[1,2,4]triazolo[4,3-a]quinoxaline-1-amine with different amines and triazole-2-thiol. Some of the synthesized compounds were subjected to antiviral and cytoxtoxicity screening using plaque-erduction assay . Most of the tested compounds exhibited cytotoxicity at concentration 160 mg/mI and compound 8b showed promising antivitral activity. In virto antimicrobial screening against different pathogenic organisms using agardiffusion method demonstrated that compounds 4d,6c,7b and 8a exhibit antibacterial and/or antifungal activities

الملخص الملخص Cyanoacetamide in heterocyclic chemistry: Synthesis, antitumor and antioxidant activities of some new benzothiophenes Cyanoacylation of 2-amino-tetrahydrobenzothiophene-3-carboxylate ethyl ester with 3-(3,5-dimethyl-1H-pyrazol-1-yl)-3-oxopropanenitrile afforded cyanoacetamide 2. The later was utilized as key intermediate for the synthesis of 3-substituted 2-iminocoumarins 3–6 and acrylamides 7a, bvia Knoevenagel condensation with 2-hydroxy-1-naphthaldehyde; 2-hydroxybenzaldehyde; 1-nitrosonaphthalen-2-ol; 7-hydroxy-5-methoxy-2-methyl-4-oxo-4H-chromene-6-carbaldehyde; 4-dimethylamino-benzaldehyde; and 4-piperidin-1-yl-benzaldehyde in EtOH/piperidine. The derivatives 7a, b did not afford the pyrazoles 8a, b upon treating with phenyl hydrazine. Furthermore, coupling of 2 with 4-amino-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one and 4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-3-amine afforded the hydrazone derivatives 9 and 10, respectively. The later derivative 10 was cyclized in acetic acid to afford the pyridopyrazolotriazine 11. Finally, 2 was treated with dimethylformamide-dimethylacetal (DMF-DMA) to afford the dimethylaminoacrylamide 12 which underwent transamination with 4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-3-amine to afford the pyrazole 13. Cyclization of compound 13 in acetic acid or pyridine was unsuccessful. The antitumor and antioxidant activities of the synthesized products were evaluated; several were found to exhibit promising antioxidant activities. J. Heterocyclic Chem., (2011).

الملخص الملخص Efficient Regioselective Three-Component Domino Synthesis
of 3-(1,2,4-Triazol-5-yl)-1,3-thiazolidin-4-ones as Potent
Antifungal and Antituberculosis Agents In research for promising antibacterial and antifungal compounds, a series of 2-aryl 3-[1,2,4]triazol-5- yl 4-thiazolidinones 1 were synthesized by a domino reaction of 5-amino-1H-[1,2,4]triazoles 3, aromatic aldehydes, and a-mercaptoacids in boiling toluene in the presence of molecular sieves 4 A° . Of the twenty novel 3-[1,2,4]triazol-5-yl 4-thiazolidinone derivatives, four compounds 2-benzo[d][1,3]dioxol-6- yl-3-[(3-morpholin-4-yl)-1H-1,2,4-triazol-5-yl)]-1,3-thiazolidin-4-one (1i), 2-(4-chlorophenyl)-5-methyl-3-[3- (4-methylpiperazin-1-yl)-1H-1,2,4-triazol-5-yl]-1,3-thiazolidin-4-one (1p), 2-benzo[d][1,3]dioxol-6-yl-3-[3- (4-methylpiperazin-1-yl)-1H-1,2,4-triazol-5-yl]-1,3-thiazolidin-4-one (1s), 2-benzo[d][1,3]dioxol-6-yl-5- methyl-3-[3-(4-methylpiperazin-1-yl)-1H-1,2,4-triazol-5-yl]-1,3-thiazolidin-4-one (1t) exhibited MICs of 4 mg/mL or less versus Mycobacterium tuberculosis. Moreover, these compounds were screened against Candida albicans. Compounds 1p, 1s gave MICs of 1 mg/mL or less, and were fungicidal. Finally, compound 1s was evaluated against an expanded fungal panel and showed good activity against Cryptococcus neoformans. In addition, compound 1s also appeared to be fungicidal against Aspergillus arrhizus, with MIC <1 mg/mL.

الملخص الملخص Dicationic phenyl-2,20-bichalcophenes and analogues as antiprotozoal agents A series of phenyl-2,2’-bichalcophene diamidines 1a–h were synthesized from the corresponding dinitriles either via a direct reaction with LiN(TMS)2, followed by deprotection with ethanolic HCl or through the bis-O-acetoxyamidoxime followed by hydrogenation in acetic acid and EtOH over Pd–C. These diamidines show a wide range of DNA affinities as judged from their DTm values which are remarkably sensitive to replacement of a furan unit with a thiophene one. These differences are explained in terms of the effect of subtle changes in geometry of the diamidines on binding efficacy. Five of the eight compounds were highly active (below 6 nM IC50) in vitro against Trypanosoma brucei rhodesiense (T. b. r.) and four gave IC50values less than 7 nM against Plasmodium falciparum (P. f.). Only one of the compounds was as effective as reference compounds in the T. b. r. mouse model for the acute phase of African trypanosomiasis
