Synthesis, characterization, and biological properties of nano-rare earth complexes with L-glutamic acid and imidazole

Synthesis and Biological Studies of Some Lanthanide Complexes of Schiff Base

“…The bacterium suspension concentration was controlled as 5 £ 10 5 to 5 £ 10 6 cfu mL ¡1 ; The diameters of filter paper were 5 mm, and for the experiments flat plates were incubated at 37 C (bacterium) for 18-24 h. Their inhibition diameter (including filter paper) was measured with a Vernier caliper. [30] The experiments were repeated three times and the results were expressed in average values.…”

“…Because of the importance of lanthanide complexes and our interest in the synthesis of lanthanide complexes, [3,9,15,29,30] we report herein the synthesis, spectroscopic studies, thermal investigation, and biological activities of lanthanide complexes with isoniazid furalacylhydrazone and sodium salicylate, in continuation of our research to develop some new antitumor and antibacterial agents that may provide useful basis for the application in biological activities for lanthanide complexes and other related fields. [3] Experimental Materials Ln(NO 3 ) 3 ¢6H 2 O was purchased from Aladdin; RPMI 1640 and tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) were purchased from Sigma; fetal calf serum (FCS) was purchased from GiBCo, No.1165723; sodium dodecylsulfate (SDS)was purchased from Sino-American Biotechnology.…”

Study on the antibacterial mechanism of copper ion- and neodymium ion-modified α-zirconium phosphate with better antibacterial activity and lower cytotoxicity

“…As seen, Na@ZrP showed poor antibacterial activity, because the viable colonies of E. coli and S. aureus remained essentially unchanged. The definite antibacterial activity of Nd@ZrP was observed because the viable colonies of E. coli and S. aureus was reduced, which was due to the release of many free hydroxyl radicals [20,21]. Cu@ZrP showed excellent antibacterial effect against E. coli or S. aureus, which was because of the "contact killing" process of Cu 2+ when it contacted the bacteria [7].…”

Synthesis, crystal structure, luminescent property and antibacterial activity of lanthanide ternary complexes with 2,4,6-tri(2-pyridyl)-s-triazine

“…In vitro antibacterial activity of the ligands and rare earth complexes against Escherichia coli (E. coli)was studied by using the filter paper disc diffusion method [26,27]. 0.004, 0.008 and Scheme 1.…”

“…However, studies on biological activities of the rare earth metal complexes with TPTZ have not been reported. In vitro antibacterial activity of the ligands and rare earth complexes against E. coli was studied by using the filter paper disc diffusion method [26,27,50]. As shown in Table 5 and Fig.…”
