A set of novel hydrazone derivatives were synthesized and analyzed for their biological activities. The compounds were tested for their inhibitory effect on the phosphorylating activity of the protein kinase CK2, and their antioxidant activity was also determined in three commonly used assays. The hydrazones were evaluated for their radical scavenging against the DPPH, ABTS and peroxyl radicals. Several compounds have been identified as good antioxidants as well as potent protein kinase CK2 inhibitors. Most hydrazones containing a 4-N(CH3)2 residue or perfluorinated phenyl rings showed high activity in the radical-scavenging assays and possess nanomolar IC50 values in the kinase assays. 相似文献

In this study the rational design, synthesis, and anticancer activity of quinoline‐derived trifluoromethyl alcohols were evaluated. Members of this novel class of trifluoromethyl alcohols were identified as potent growth inhibitors in a zebrafish embryo model. Synthesis of these compounds was carried out with an sp3‐C?H functionalization strategy of methyl quinolines with trifluoromethyl ketones. A zebrafish embryo model was also used to explore the toxicity of ethyl 4,4,4‐trifluoro‐3‐hydroxy‐3‐(quinolin‐2‐ylmethyl)butanoate ( 1 ), 2‐benzyl‐1,1,1‐trifluoro‐3‐(quinolin‐2‐yl)propan‐2‐ol ( 2 ), and trifluoro‐3‐(isoquinolin‐1‐yl)‐2‐(thiophen‐2‐yl)propan‐2‐ol ( 3 ). Compounds 2 and 3 were found to be more toxic than compound 1 ; apoptotic staining assays indicated that compound 3 causes increased cell death. In vitro cell proliferation assays showed that compound 2 , with an LC50 value of 14.14 μm , has more potent anticancer activity than cisplatin. This novel class of inhibitors provides a new direction in the discovery of effective anticancer agents. 相似文献

将异佛尔酮二胺(IPDA)和甲基丙烯酸十二氟庚酯(DFMA)进行Micheal加成反应,合成端仲胺基的有机氟化合物(DFMA-IPDA)。以该化合物为扩链剂、聚醚改性聚二甲基硅氧烷(PDMS)为二元醇,与异佛尔酮二异氰酸酯(IPDI)、聚氧化丙烯二醇(PPG)、二羟甲基丙酸(DMPA)聚合制备了有机氟和硅改性的水性聚氨酯(WPU),研究了有机氟和/或硅用量对WPU乳液性能和胶膜性能的影响。结果表明:用该方法合成的DFMA-IPDA纯度达99.2%,和一定量的PDMS共改性可合成稳定的WPU乳液。随两者用量的增加,WPU乳液的平均粒径增大,胶膜的热稳定性、耐水性提高,表面水接触角增大。PDMS可提高WPU胶膜的柔性,而DFMA-IPDA可提高胶膜的韧性。用PDMS和DFMA-IPDA共改性能获得综合性能优异的WPU,当扩链剂完全采用DFMA-IPDA,PDMS用量为4%时,WPU胶膜的吸水率为4.5%,水接触角达到102.3°。 相似文献
