1Advances in dye-sensitized solar cell显示文摘THE conversion of visible light to electricity using semiconductors as light absorbers has beenan important area of research for many years. In the 1970s, highly efficient photovoltaiccells based on silicon were developed (the light-to-electrical conversion efficiency≥25%),which provides energy to aircrafts. Then semiconductor liquid-junction photoelectrochemicalcell started to be investigated. Generally speaking, highly efficient liquid-junction photoelec-trochemical solar cells can be obtained by using semiconductors such as Si, GaAs and WSe.(band gap≈(1.3±0.3) eV). Conversion efficiencies over 15% have been acquired on solarcells consisting of single crystals of Si or GaAs. But the serious photocorrosion and highJing, BW Zhang, MH Shen, T 1997Chinese Science Bulletin1997,42,23:6
2Design,synthesis,and anti-inflammatory evaluation of a series of novel amino acid-binding 1,5-diarylpyrazole derivatives显示文摘Aim: To design and synthesize a series of novel amino acid-binding 1,5-diarylpyrazole derivatives, which are intended to act as prodrugs with better aqueous solubility than celecoxib, and which will exert potent anti-inflammatory activi-ties after being converted to their parent compounds in vivo. Methods: To introduce an amino acid, celecoxib analogs containing amino or methylamino group were synthesized first through multi-step chemical reactions. All the synthesized compounds were screened in an intact cell-based assay in vitro and in carrageenan-induced mouse paw edema in vivo. Some active compounds were selected for further evaluation in a carrageenan-induced rat paw edema model. The preliminary pharmacokinetics experiments were conducted using high performance liquid chromatography/mass spectrometry (HPLC/MS). Results: Celecoxib, 6 of the 1,5-diarylpyrazole class of celecoxib analogs, and their amino acid derivatives (hydrochloride salts) were synthesized. In vitro screening, the hydrochloride salts showed decreased inhibitory effects on cyclooxygenase (COX)- 1 and COX-2 compared with their parent compounds, but some exhibited potent anti-inflammatory activity in vivo. Compound 4a was selected for further evaluation, and its anti-inflammatory effect was equivalent to that of celecoxib after oral administration in the carrageenan-induced rat paw edema model. At three doses (25 mg/kg, 50 mg/kg, and 100 mg/kg) the percentage inhibition on edema was 20.7%, 52.6%, and 62.6% (for compound 4a) and 27.8%, 38.4%, and 40.1% (for celecoxib), respectively. Preliminary pharmacokinetic evaluations support the hypothesis that compound 4a was actually converted to its parent compound, compound 4. Conclusion: The compound bound with amino acid acts like prodrug, which can exert anti-inflammatory effect similar to celecoxib after being converted to its parent compound. This finding will be of great benefit in carrying out structural modifications of prodrug-like selective COX-2 inhibitors.Li MH Yin LL Cai MJ Zhang WY Huang Y Wang X Zhu XZ Shen JK 2005Acta Pharmacologica Sinica2005,26,7:2
