Abstract:

The synthesis and properties of explosive urea and triazine derivatives is investigated on behalf of the explosive parameters and the full characterization of the molecules. (Chapter I-III) The class of oxadiazole derivatives is enhanced from the known explosive 1,2,5 oxadiazole (furazane) derivatives to the 1,2,4 oxadiazole derivatives. This molecule class is thoroughly investigated by all terms of chemical and explosive material matter and especially the 1,2,4-oxadiazol-5-one derivatives are compared to the corresponding tetrazole derivatives which were by far the most investigated molecule

Diese Arbeit befasst sich mit dem Einfluss der molekularen Struktur von 2,5-Diphenyl-1,3,4-Oxadiazol-Derivaten auf die Präparierung dünner Schichten mittels Vakuumdeposition. Dünne Schichten von diesen Substanzen wurden auf Si/SiO2 aufgedampft und ihre Struktur systematisch mittels XSR, AFM und IR untersucht. Das Ergebnis zeigt, dass die Schichtstrukturen offenbar von Substratetemperatur (Ts) abhängig sind. Im untersuchten Ts-Bereich bilden etherverbrückte Oxadiazole immer geordnete Schichten und die Schichtperiodicität hängt linear von der Längen der aliphatischen Ketten, während sich bei den

Abstract:

Signal Transducers and Activators of Transcription factors (STATs) are a class of latent cytoplasmic proteins that regulate cell growth and survival by modulating the expression of specific target genes. One member of the STAT family, STAT3, has received particular attention since it has been found constitutively activated in a broad spectrum of cancer cell lines and human tumors. These compelling results, combined with a well-known selectivity of STAT3 inhibitors for tumor cells, validated STAT3 as a promising anticancer drug target.

Abstract:

Considering the importance of nitrogen-rich heterocycles in drug discovery, a novel strategy towards heterocycle synthesis was envisioned using cyanamide chemistry. Synthesis which involve mild conditions, avoids multi-step sequence and non-toxic reagents are desirable for generation of large combinatorial libraries of drug molecules. We envisaged that the NCN linkage of the cyanamide as well as the concomitant use of the nucleo-and electrophilic centres of the cyanamide could provide a novel synthetic route towards nitrogen heterocycles.

博士<br>國立臺灣大學<br>化學研究所<br>97<br>In this thesis, we synthesized multi-(1,3,4-oxadiazo-2-yl)benzene and biphenyl derivatives. The conformational and substitution effects were studied by photophysical properties and cyclic voltammetry. For the fluorescence and phosphorescence of 2,2’-(1,3,4-oxadiazo-2-yl)biphenyl(BOBP) showed good spectra matching with absorption spectra of MLCT1 and MLCT3 transition of Ir(ppy)3. While BOBP was used as host material for Ir(ppy)3 in PHOLED device, the maximum brightness of 43,000 cd/m2 with efficiency of 26 cd/A at 200 cd/m2 was achieved. The first-reduction pote

碩士<br>國立交通大學<br>應用化學系碩博士班<br>101<br>In part 1, we successfully synthesized 1,2,4-oxadiazloe derivatives 24, 30a, 30b and 30c using 1,3-dipolar cycloaddtion reaction of anthryl nitrile oxide with a nitrile group. Compound 24 was found to show a high selectivity toward Fe3+ (among 18 different metal ions) in CH3CN with a strong fluorescence quenching. Compound 24 underwent a Fe3+-induced irreversible oxidation to afford compound X1 as the major product and compounds 25 and 26 as minor products. Compounds X1, 25 and 26 were isolated and characterized by organic spectroscopic data; furthermore, th
