Abstract Background Dengue virus (DENV) infection is spreading rapidly, especially in the subtropical and tropical regions, placing a huge percentage of global population at risk causing repeated outbreaks. DENV protease inhibition has been suggested as viable therapeutic strategy. Using computer-aided design approach structure-based drug approach, ten 1, 2, 4-oxadiazole derivatives were design...

The synthesis of some new 1,3,4-oxadiazole derivatives and 1,2,4-triazine-5-one has been described. IR, H NMR and mass spectral data support the structures of newly synthesized compounds. All the compounds have been tested in vivo for their anti-inflammatory activity by carrageenin-induced rat paw edema method. The compounds, which show good antiinflammatory activity, have been screened for the...

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...

in the last three decades investigations in the field of oxadiazoles have been intensified due to their diverse therapeutic uses. oxadiazole are well known to have a wide range of therapeutic activities namely anti-inflammatory, analgesic, antipyretic, anticonvulsant, antiparasitic, antimicrobial etc. in this study, we have evaluated the antimicrobial activity of some carboxymethyl derivatives ...

A series of substituted 1,3,4-oxadiazole derivatives 2a-e and 4a-e have been synthesized from diphenyl acetic acid hydrazide under various reaction conditions. These compounds have been tested in-vivo for their anti-inflammatory and analgesic activities. The compound 2-[(5-diphenylmethyl-1,3,4-oxadiazol-2-yl)sulfanyl]-N-(3-chloro-4-fluro-phenyl)acetamide 4b has emerged as the most active compou...

In the title compound, C(23)H(20)F(3)N(5)O, the piperazine ring adopts a chair conformation. The quinoline ring makes dihedral angles of 56.61 (11), 49.94 (12) and 42.58 (14)° with the piperazine ring, the 1,3,4-oxadiazole ring and the benzene ring, respectively. An intra-molecular C-H⋯O hydrogen bond generates an S(7) ring motif. In the crystal, mol-ecules are linked into infinite chains along...
