The title compound, C(9)H(12)N(2)O(3), was synthesized by the reaction of ethyl 2-(4-meth-oxy-phen-oxy)acetate with hydrazine hydrate in ethanol. In the acetohydrazide group, the N-N bond is relatively short [1.413 (2) Å], suggesting some degree of electronic delocalization in the mol-ecule. In the crystal, mol-ecules are linked into sheets lying parallel to the ab plane by N-H⋯N and N-H⋯O hydr...

In the title compound, C(8)H(9)ClN(2)O(2), the two planar fragments, i.e. the chloro-phenyl and C-C(=O)-N groups, are inclined at 14.93 (17)°. In the crystal, relatively weak inter-molecular N-H⋯N, C-H⋯O and N-H⋯O hydrogen bonds connect the mol-ecules into layers. The hydro-phobic parts of mol-ecules stick outside these layers and are connected with the neighbouring layers only by van der Waals...

A series of novel uracil derivatives, bearing N-(4-phenoxyphenyl)acetamide moiety at N3 of a pyrimidine ring, has been synthesized. Their antiviral activity has been evaluated. It has been found that the novel compounds possess high inhibitory activity against replication of human cytomegalovirus (AD-169 and Davis strains) in HEL cell cultures. In addition, some of the derivatives proved to be ...

Purpose: To evaluate antibacterial activity of a series of molecules bearing 1,3,4-oxadiazole and azomethine moieties. Methods: The 4-chlorobenzoic acid (1) was precursor to N'-substituted-2-(5-(4-chlorophenyl)-1,3,4oxadiazol-2-ylthio)acetohydrazide, 8a-p, through a multistep synthesis of corresponding ester, 2, hydrazide, 3 and 1,3,4-oxadiazole, 4. The molecule, 4, was subjected to electrophil...

To investigate the cytotoxicity mechanism of quinocetone from the perspective of chemical structure, quinocetone and other new quinoxaline-1, 4-dioxide derivatives were synthesized, and evaluated for their activities, and analysed for the metabolic characteristics. Quinocetone and other new quinoxaline-1,4-dioxide derivatives were synthesized, and evaluated for their activities, and analysed fo...
