Glycogen phosporylase (GP) is a promising target for the control of glycaemia. The design of inhibitors binding at the catalytic site has been accomplished through various families of glucose-based derivatives such as oxadiazoles. Further elaboration of the oxadiazole aromatic aglycon moiety is now reported with 3-glucosyl-5-amino-1,2,4-oxadiazoles synthesized by condensation of a C-glucosyl am...

The title compound, [Cu(C(11)H(11)N(4)O(2))(2)], was prepared by solvothermal synthesis using 2-amino-5-(4-methoxy-phen-yl)-1,3,4-oxadiazole and copper sulfate penta-hydrate in an acetonitrile solution. The Cu(II) atom lies on an inversion center and is four-coordinated in a slightly distorted square-planar geometry by four N atoms of the ligands obtained from the formation of a bond between th...

The title compound, C(18)H(23)N(3)O(3), crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The phenyl ring and the 1,2,4-oxadiazole ring are inclined to one another by 19.9 (3)° in mol-ecule A and 7.3 (3)° in mol-ecule B. The absolute structure of the title compound was referred to the transfered chiral center (S) of one of the starting reacta-nts. In the crystal, A ...

In the present investigation, two novel series of 2-[3-(4-chlorophenyl)propan-3-one]-5-(substituted phenyl)-1,3,4-oxadiazole and 2-[3-(4-ethylphenyl)propan-3-one]-5-(substituted phenyl)-1,3,4-oxadiazole were synthesized and tested for their antiinflammatory, analgesic, ulcerogenic and antibacterial actions. A fair number of compounds were found to have very good antiinflammatory activity in car...

In the title compound, C(10)H(8)N(2)O(3), the oxadiazole ring is essentially planar, with a maximum deviation of 0.006 (1) Å for the two-connected N atom. The mean planes through the aldehyde unit and the methyl-substituted phenyl ring make inter-planar angles of 13.60 (9) and 59.69 (4)°, respectively, with the oxadiazole ring. In the crystal structure, adjacent mol-ecules are inter-connected i...

In the title compound, C(20)H(22)N(2)O(5), the central 1,3,4-oxadiazole ring is essentially planar [r.m.s. deviation from the best plane of 0.0011 Å] and makes dihedral angles of 4.10 (3) and 13.32 (4)° with the two benzene rings. In the crystal structure, the packing is stabilized by weak non-classical inter-molecular C-H⋯N hydrogen bonds, which link the mol-ecules into an extended network.

A variety of sulfonamidomethane linked 1,3,4-oxadiazoles and 1,3,4-thiadiazoles were prepared and tested for antioxidant activity. The methyl substituted arylsulfonylaminomethyl-1,3,4-oxadiazole 9b showed excellent antioxidant activity.

     New derivatives of 2-[2-(2-Chlorophenoxy)phenyl]-1,3,4-oxadiazole as candidates for agonistic effect on benzodiazepine receptors were synthesized. Conformational analysis and superimposition of energy minima conformers of the novel compounds on estazolam, a known benzodiazepine agonist, revealed that the main proposed benzodiazepine pharmacophores were well matched. In pharmacological eval...
