We designed and synthesized a single polymer with TADF characteristics by grafting the TADF emitter, 10-(4-(5-phenyl-1,3,4-oxadiazol-2-yl)phenyl)-10H-phenoxazine, onto the side chain of the polymer backbone of polycarbazole. Employing these copolymers as emitting layers, an efficient bluish-green polymer LED with a maximum external quantum efficiency of 4.3% was achieved, corresponding to a hig...
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...
5-Isopropyl-6-(5-methyl-1,3,4-oxadiazol-2-yl)-N-(2-methyl-1H-pyrrolo[2,3-b]pyridin-5-yl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (BMS-645737) is a potent and selective vascular endothelial growth factor receptor-2 antagonist. In this study, liquid chromatography/tandem mass spectrometry and NMR were used to investigate the biotransformation of BMS-645737 in vitro and in the cynomolgus monkey, dog, ...
In the crystal structure of the title compound, C(9)H(9)N(3)O, adjacent mol-ecules are linked through N-H⋯N hydrogen bonds into a three-dimensional network.
5-(3-methoxyphenyl)-3-(5-methyl-1,2,4-oxadiazol-3-yl)-2-oxo-1,2-dihydro-1,6-naphthyridine (AC-3933) is a novel cognitive enhancer with central benzodiazepine receptor partial inverse agonistic activity. AC-3933 is predominantly metabolized to hydroxylated metabolite [SX-5745; 3-(5-hydroxymethyl-1,2,4-oxadiazol-3-yl)-5-(3-methoxyphenyl)-2-oxo-1,2-dihydro-1,6-naphthyridine] in dog. Initially, we ...
New 3-substituted 1-(3-hydroxyphenyl)-5-oxopyrrolidine derivatives containing hydrazone, azole, diazole, oxadiazole fragments, as well as 2-phenoxy- and 2,3-diphenoxy-1,4-naphthoquinone derivatives were synthesized. The structure of all compounds has been confirmed by NMR, IR, mass spectra, and elemental analysis data. Methyl 1-{3-[(3-chloro-1,4-dioxo-1,4-dihydro-2-naphthalenyl)oxy]phenyl}-5-ox...
In the title syndone (1,2,3-oxadiazol-3-ylium-5-olate) compound, C(21)H(16)ClN(5)O(4)S, the dihedral angle between the benzene and oxadiazole rings is 55.62 (11)° and that between the triazine and the chloro-substituted phenyl rings is 82.45 (9)°. There is an intra-molecular C-H⋯S hydrogen bond, which generates an S(5) ring motif. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrog...
Matrix metalloproteinases (MMPs) are important proteases involved in tumor progression including angiogenesis, tissue invasion, and migration. Therefore, MMPs have been reported as potential diagnostic and prognostic biomarkers in many types of cancer. New oxadiazole, thiadiazole, and triazole derivatives were synthesized and evaluated for their anticancer effects on A549 human lung adenocarcin...
5-Phenyl/methyl-5-morpholinomethyl/pyrrolidinomethyl-2-(5- aryl-1,3,4-oxadiazol-2-yl)imino]-4-thiazolidinones (5a-m) were synthesized by the reaction of 5-phenyl/methyl-2-[(5-aryl-1,3,4-oxadiazol -2-yl)imino]-4-thiazolidinones (4a-j) with formaldehyde and morpholine or pyrrolidine. The structures of the compounds were determined by analytical and spectral (IR, 1H-NMR, EIMS) methods. The antibac...
