Eu(III) and Tb(III) Schiff base complexes are applicable in various fields such as sensing, assays, screening protocols in vitro, and imaging studies in vitro or in vivo. Fluorescent europium and terbium complexes and their interaction with cell penetrating peptide (KKKRKC) can represent an excellent key for understanding pathway of peptide transportation though cell membrane and the application of
Eu(III)和Tb(III)Schiff碱配合物可用于各种领域,例如传感,测定,体外筛选方案以及体外或体内成像研究。荧光euro和complex络合物及其与细胞穿透肽(KKKRKC)的相互作用可能是理解肽通过细胞膜转运途径以及席夫碱复合物作为潜在抗菌药物的应用的极佳钥匙。测试了席夫碱金属配合物及其与肽的结合物对铜绿假单胞菌和鼠伤寒沙门氏菌的抗菌活性。与肽结合的席夫碱金属配合物对正常人PNT1A细胞毒性较小,对铜绿假单胞菌具有很高的抗菌活性和鼠伤寒沙门氏菌,其中铜绿假单胞菌和鼠伤寒沙门氏菌的IC50分别降至125.9和/或36.1 µM 。我们的结果有力地表明,与肽结合的席夫碱金属配合物具有很大的潜力,可以被开发成高效的抗菌药物。
