New and efficient approach for synthesis of novel bioactive [1,3,4]thiadiazoles incorporated with 1,3-thiazole moiety
摘要:
A series of novel 1,3,4-thiadiazoles incorporated with thiazole moiety was synthesized by reaction of 5-acetyl-2-benzoylimino-3-phenyl-1,3,4-thiadiazole thiosemicarbazone 2 with each of N-phenyl 2-oxopropanehydrazonoyl chloride 3 and ethyl (N-aryl-hydrazono) chloroacetate 5 in dioxane in basic medium. Also, another series of 1,3,4-thiadiazole incorporated with thiazole moiety was prepared by reaction of 5-acetyl-2-benzoylimino-3-phenyl-1,3,4-thiadiazole thiocarbohydrazone with each of hydrazonoyl chlorides 3, 5 and 18 under the same reaction conditions. The mechanisms of the studied reactions were discussed and the assigned structure for each of the new products was identified via elemental and spectral data and by alternative method whenever possible. Moreover, the antimicrobial activity for some selected products was screened, and the results obtained exploring the high potency of some of the tested compounds compared with the employed standard bactericides and fungicide.

the new derivatives. The antitumor activities of synthesized N-phenylmorpholine-thiazole derivatives were investigated against three tumor cells namely, TK-10, MCF-7 and UACC-62. The results of such investigation indicated that some derivatives showed good potential to inhibit the growth of the two cells of the tested tumor cells. One of the tested compounds, N-ethyl thiosemicarbazone derivative 7 revealed

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

Two series of 6-arylazothiazol[2,3-c][1,2,4]triazoles were prepared via oxidative cyclization of the respective aldehyde N-(5-arylazo-4-methylthiazol-2-yl)-hydrazones. The structures of the latter hydrazone precursors and the azo compounds were confirmed by spectral and elemental analyses. The solvatochromism of the title azo dyes is evaluated by means of the Kamlet--Taft equation and discussed.
