Studies on heterocyclic compounds. I - Synthesis of some new 1,2,4-triazole derivatives.
In the present study, starting compound 4 was prepared by deamination of compound 2 in the presence of hypophosphorous acid and sodium nitrite. Treatment of compound 4 with ethyl bromoacetate produced ethyl[3-(4-chlorophenyl)-5-(4-methoxybenzyl)-4H-1,2,4-triazol-4-yl]acetate (5), which was converted to the hydrazide derivative (6) by treatment with hydrazine hydrate. The reaction of compound 6 ...
متن کاملStudies on the Synthesis of Novel 2,4-Thiazolidinedione Derivatives with Antidiabetic Activity
A new series of thiazolidinedione derivatives were synthesized. The structures of these compounds were established by means of IR, 1H-NMR and elemental analysis. All of the compounds were screened for antidiabetic activity on albino rats. Most of the compounds showed significant antidiabetic activity when compared with the standard drug glibenclamide.
متن کاملSynthesis and studies on antioxidants: ethoxyquin (EQ) and its derivatives.
In our study ethoxyquin (EQ) and its two complexes with flavonoids were obtained from ethoxyquin (1,2-dihydro-6-ethoxy-2,2,4-trimethylquinoline, EQ) and quercetin (EQ-Q, 1:1) or rutin (EQ-R, 1:1). Cytotoxicity of the tested compounds was studied using the trypan blue exclusion method and the properties of the studied compounds were also analyzed with the TUNEL method evaluating their ability to...
متن کاملStudies on pyrazine derivatives. XLVII. Synthesis and antibacterial activity of novel pyrazine derivatives with amidoxime moiety.
The new pyrazine derivatives exhibiting an antibacterial activity have been synthesized. Initial amidoxime 1 was obtained in the reaction of pyrazinecarbonitrile with hydroxylamine. Upon treatment of amidoxime with methyl iodide O-methyl derivative 2 was formed. Both amidoximes were transformed into imidoyl chlorides 3, 4. Then the chloride atom in those derivatives was substituted with various...
