Chemical Research in Chinese Universities 2008年第4期24卷 454-458页

作者： LIU Xin-hua ZHI Li-ping SONG Bao-an XU Hong-li Key Laboratory of Anhui Educational Department Faculty of Mathematics ＆ Physics Anhui University of Technology Ma ＇anshan 243002 P R. China Key Laboratory of Green Pesticide and Agriculture Bioengineering Ministry of Education Guizhou University Guiyang 550025 P. R. China

Eleven new 1-{5-[4-（benzyloxy）phenyl]-3-methyl-4,5-dihydropyrazol-l-yl} oxime ester dcrivatives were synthesized and characterized by elemental analysis, HRMS, ^1H NMR data. All the compounds were screened for their antibacterial potential in vitro against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The results indicate that compounds 8c and 8f possess potent activity with the minimum inhibitory concentrations（MIC） of 1.562--3.125 ug/mL against all the four bacteria. Compounds 8c, 8e and 8f show moderate inhibition against the DNA gyrase（IC50=1.9--2.5 ug/mL）. On the basis of the biological activities, structure-activity relationship was discussed.

Synthesis and Anticancer Activity of 2,3,4-Trimethoxyacetophenoxime ester Containing Benzothiazole Moiety

引用

Chinese Journal of Chemistry 2005年第9期23卷 1236-1240页

作者：宋宝安刘新华杨松胡德禹金林红张华 Key Laboratory of Green Pesticide and Agricultural Bioengineering Ministry of Education Center for Research and Development of Fine Chemicals Guizhou University Guiyang Guizhou 550025 China

A series of 2,3,4-trimethoxyacetophenoxime esters containing benzothiazole moiety were synthesized by the reaction of oxime with acyl chloride in alkaline medium. Their structures were established by elemental analysis, IR, and ^1H NMR spectra. The bioassay tests showed that these title compounds exhibit moderate anticancer activity in vitro by MTT method and compounds 6c and 6d could inhibit ERK phosphorylation in NIH 3T3 cell induced by PDGF.
