In the title complex, C(8)H(7)N(3)O, the C-O [1.369 (2) and 1.364 (3) Å] and C=N [1.285 (3) and 1.289 (3) Å] bond lengths in the oxadiazole ring are each almost identical within systematic errors, although different substituents are attached to the ring. The phenyl ring is inclined to the planar oxadiazole ring [r.m.s. deviation 0.002 Å] by 13.42 (18)°. In the crystal, molecules are linked via ...

In the title compound, C(16)H(14)ClN(3)O(2), the 2,3-dihydro-1,3,4-oxadiazole ring [maximum deviation = 0.030 (1) Å] and the pyridine ring [maximum deviation = 0.012 (1) Å] are inclined slightly to one another, making a dihedral angle of 11.91 (5)°. The chloro-substituted phenyl ring is almost perpendicular to the 2,3-dihydro-1,3,4-oxadiazole and pyridine rings at dihedral angles of 86.86 (5) a...

Introduction: Leukemia is considered one of the main causes of death, and current chemotherapeutic agents are unable to provide optimal responses due to chemo-resistance. Therefore, there is a constant need for new drugs. Cyclooxygenase- 2 (COX-2) inhibitors can be helpful by reducing the necessary dose of routine chemotherapeutic drugs. Herein, we evaluated the cytotoxicity activity as well...

Disc-shaped liquid crystals designed by introducing oxadiazole functional units into a heterocoronene system were explored in thin-film space-charge limited current (SCLC) devices. They found to exhibit ambipolar semiconducting behavior.

Three new 1,3,4-oxadiazole, 1,3-thiazolidine and 1,2,4-triazole derivatives were obtained starting from furan-2-carbohydrazide. Then, 1,2,4-triazole compound was converted to the corresponding Mannich bases using several secondary amines including piperidine, piperazine, morpholine or thiomorpholine moiety. The synthesis of 5-(furan-2-yl)-4-{[(4-methoxyphenyl)methylidene]amino}-4H-1,2,4-triazol...

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 derivativ...

The reaction of p-bromoanilino acetohydrazide(II) with aromatic aldehydes in alcohol yielded 2-[4-bromo aniline] N-substituted benzylidine hydrazides (IIIa-IIIj), which in presence of yellow mercuric oxide and iodine in DMF, yielded corresponding 4-bromo[(N-5-substituted 1,3,4 oxadiazole-2 -yl)methyl]aniline (IVa-IVj). Structures of the compounds synthesized were confirmed by IR, (1)HNMR and MA...
