摘要：磺胺是应用最早的一类化学合成抗菌药,在治疗感染性疾病中起着重要作用,因此许多研究致力于磺胺类化合物的深入开发.母体结构对氨基苯磺酰胺经化学结构修饰后呈现广泛的生物活性,显示出巨大的药用潜力和开发价值,相关研究异常活跃.结合本课题组研究,参考国内外近5年文献,本文系统地综述了磺胺母体结构不同部位的化学结构修饰及其衍生物,包括其金属超分子络合物在抗微生物、抗癌、抗寄生虫、消炎镇痛、抗惊厥、抗青光眼、抗糖尿病、抗癫痫及相关神经性疾病和利尿药等药用研发新情况,并展望了其发展趋势.希望为广谱性、高活性和低毒性磺胺类新药分子的合理设计提供指导,为开拓磺胺类化合物的用途提供新思路.

摘要：A series of chalcone-benzotriazole conjugates as new potential antimicrobial agents were synthesized and char- acterized by ^1H NMR, ^13C NMR, IR and HRMS spectra. Antimicrobial assay manifested that some target com- pounds gave moderate to good antibacterial and antifungal activities. The N- 1 derived benzotriazole 5e and N-2 de- rived benzotriazole 6a exhibited valuable inhibitory efficacy against some tested strains. Especially, derivative 6a gave superior antifungal efficacies against C. utilis, S. cerevisiae and A. flavus （MIC^0.01, 0.02, 0.02 gmol/mL, respectively） to Fluconazole. The drug combination of compound 5e or 6a with antibacterial Chloromycin, Nor- floxacin and antifungal Fluconazole respectively showed stronger antimicrobial efficiency with less dosage and broader antimicrobial spectrum than their separated use alone. The preliminary interaction with calf thymus DNA revealed that compound 6a could intercalate into DNA to form 6a-DNA supramolecular complex which might be a factor to exert its powerful bioactivity. Molecular docking study indicated strong binding of compound 6a with DNA gyrase. The structural parameters such as molecular orbital energy and molecular electrostatic potential of compound 6a were also investigated, which provided better understanding for its good antimicrobial activity.
