Novel 2-thiazolylphthalazine derivatives were efficiently synthesized underultrasoundirradiation, resulting in high yields and short reaction times after optimization of the reaction conditions. All prepared compounds were fully characterized using spectroscopic methods. They were screened for their antimicrobial activity against Gram-positive and Gram-negative bacteria as well as for antifungal

4-diazabicyclo[2.2.2] octane) as an eco-friendly catalyst using the solvent-drop grinding method. The structure of the synthesized compounds was elucidated using elemental and spectroscopic analyses (IR, NMR, and Mass). The activity of these compounds against human hepatocellular carcinoma cell line (HepG2) was tested and the results showed that the pyrazoline 11f, which has a fluorinesubstituent, is the most

Abstract Unsymmetrical azines were synthesized from reaction of C-coumarinoyl-N-arylformohydrazonoyl bromide with different alkyl carbodithioates. In addition, reactions of hydrazonoylhalides with thioanilide and methyl dithioates were studied. The structures of newly synthesized compounds were confirmed by elemental analyses, spectroscopic tools, and alternative syntheses whenever possible.

pharmacological activities. Objective: Synthesis of new chalcones and utilizing them as a building block for constructing a series of thiazole derivatives and evaluating some of them as anticancer agents. Method: The new compounds were synthesized via stirring at room temperature or thermal heating. Cytotoxic evaluation of the new synthesized compounds was testedusing the method of Skehan et al. Moreover

A new series of 7-arylazo-5$H$-3-(trifluoromethyl)-6-methyl-1,2,4-triazolo-[3,4-$b$]-1,3,4-thiadiazines was prepared by reaction of 4-amino-3-trifluoromethyl-5-mercapto-1,2,4-triazoles with $N$-aryl-2-oxo-propane hydrazonoyl chloride in dioxane under reflux in the presence of triethylamine. Furthermore, Schiff bases of 4-amino-5-mercapto-1,2,4-triazole derivatives were reacted with a variety of hydrazonoyl chlorides and gave the respective hydrazonothioates. In addition, the novel \textitbis}-(1,2,4-triazole-3-thione) was reacted with the appropriate hydrazonoyl chloride in dioxane under reflux in the presence of triethylamine to give the corresponding \textitbis}-(1,2,4-triazolethiohydrazonoate). The structures of the new compounds were established based on elemental and spectral data. The mechanism of the studied reaction was also discussed. Moreover, some of the new products were screened for their anticancer activity and the results obtained are promising and indicate that compounds \textbf4a }and \textbf4i} are the most active inhibitors against HEPG-2 and compounds \textbf4a} and \textbf13b} are active against HCT cell lines.
