A series of new pyrazole oxime compounds bearing a 1,2,3-thiadiazole ring were designed, synthesized, and evaluated for their insecticidal, acaricidal and antitumor activities. Bioassays demonstrated that some title compounds displayed satisfactory insecticidal and acaricidal properties. Especially, compounds 8d and 8h exhibited 90% insecticidal activities against Aphis craccivora at the concentration
设计,合成了一系列带有1,2,3-噻二唑环的新型吡唑肟化合物,并对其杀虫,杀螨和抗肿瘤活性进行了评估。生物测定表明,某些标题化合物具有令人满意的杀虫和杀螨特性。特别地,化合物8d和8h在100μg/ mL的浓度下表现出对蟹蚜的90%的杀虫活性。有趣的是,某些目标化合物在体外具有对四种人类癌细胞系的显着抗肿瘤活性。其中,化合物8e(IC50 =7.19μM),化合物8l(IC50 =6.56μM),化合物8m(IC50 =8.12μM)和化合物8r(IC50 =7.06μM)对HCT-116细胞的抑制作用均优于对照物5-氟尿嘧啶(IC50 =29.50μM)。此外,化合物8j,8m,
